The Cold Trade

Britain is on course for its hottest summer on record. Domestic air-conditioning installation requests ran 320% above last year — against an installed base of just 4.3% of English homes. And across 3,849 UK cooling, refrigeration and ventilation companies, EBITDA had already risen 23.8% in two years before the heat arrived, with the median company's headcount unchanged.

Key findings
  • 30.7% have at least one director aged 60 or over. In refrigeration alone it is 40.1%, and 12.2% have a director past 70.
  • 20.3% is the same figure for the wider plumbing and heating trade these firms are normally counted inside. The cooling specialists are half again as old.
  • £195,000 is the typical company's annual revenue. The typical firm has two staff, three quarters employ four or fewer, and only 28 turn over more than £10m.
  • 23 companies own more than one business in this trade, covering 54 between them. The biggest owns four.
  • 44.2% of the trade's measurable revenue is in the hands of owners aged 60 or over — 945 companies carrying £637m.
  • +320% year-on-year rise in domestic air-conditioning installation requests during the June 2026 heat, against an installed base of just 4.3% of English homes.

The summer that moved the demand curve

Britain is on course for its hottest summer on record.

Domestic air-conditioning installation requests ran 320% above last year. Only 4.3% of English homes have air conditioning today, and government modelling puts that near 30% by 2050. That is a decade of pent-up demand arriving at once.

What makes it interesting for acquirers is that these businesses were already growing before the heat arrived.

Across 3,849 UK cooling, refrigeration and ventilation companies, EBITDA rose 23.8% over two years — accounts covering roughly 2023 to 2025, well before this summer. And the median company's headcount did not move at all. They are running harder, not hiring. The constraint is engineers, not demand.

On 13 August 2026 the temperature at Kew Gardens reached 38.1°C — the fifth hottest day ever recorded in the United Kingdom. It was not the peak that made the summer unusual. It was the length of it.

By the Met Office's count, 2026 now holds the record for the most days at or above 36°C (four) and at or above 37°C (three). England had its warmest June in a series running back to 1884, its driest July since records began in 1836 — 6.5mm, a tenth of the average — and, along with Wales, its sunniest calendar month of any kind. Between 1 June and 10 August the UK ran 1.88°C above the 1991–2020 average, and the Met Office's mid-August assessment was that a new record British summer had become "increasingly likely".

The human cost arrived first. The UK Health Security Agency put red heat-health alerts in force across six English regions on 24 and 25 June — only the second time a red alert has ever been raised, the first being the 40.3°C episode of July 2022 — and its interim monitoring estimates 2,877 heat-associated deaths in England across the May and June episodes alone. The Grantham Research Institute at LSE put the economic cost of the June heatwave at £1.15 billion and 24 million lost working hours.

Then came the scramble. MyBuilder recorded domestic air-conditioning installation requests running 320% above the same period in 2025 — the highest level in the platform's history. Currys reported air-conditioning unit sales up 330% and fan sales up nearly 3,000% over a single heatwave weekend, with its chief executive describing supply as "pretty tight". And in the background, less visible to the public and far more consequential commercially, chilled and frozen aisles began going dark: fridge and freezer failures were reported across Sainsbury's, M&S, Morrisons and Tesco stores through late June, with stock withdrawn where temperature control could not be guaranteed.

The Cold Chain Federation issued a formal warning on 25 June that infrastructure underpinning roughly half the nation's food supply "was not designed for sustained 40°C temperatures". More than half of Britain's 460 cold storage facilities are over twenty years old.

The trade that has to absorb it

Official statistics have no code for air conditioning. Cooling is filed inside plumbing, alongside 32,559 companies that are mostly plumbers. So this study starts somewhere else: with the company name. It counts every active business whose registered name contains a cooling, refrigeration or ventilation trade word — air conditioning, refrigeration, ventilation, air handling, climate control, chiller, cooling, HVAC, heat pump. That is 3,849 companies, measured against the live Companies House register on 22 August 2026.

How many companies are there really?

Published counts for this trade range from about 4,000 to 65,000, and the spread is entirely a question of what is being counted.

The counts are NOT nested: only 1,768 of the 3,849 carry an HVAC-anchored SIC code at all, so at least 2,081 of this cohort fall outside any SIC-43220 count. They are five overlapping populations drawn on five different definitions.
Sources: ExitRadar / Companies House (cohort measured 22 August 2026) · DEFRA · ACRIB · commercial lead-list vendors — Two things drive the spread. BREADTH OF CODE — SIC 43220 is a plumbing bucket with air conditioning attached to the end of its name, so filtering on it returns mostly plumbers, and lead lists widen that further with directory entries and duplicates. And LEGAL FORM — Companies House holds only incorporated businesses, so no register-based count, including ours, can see a sole trader with a van. That tail is real and unmeasurable from here, which is one more reason to read the first row as a floor. The F-gas figure is the closest thing to an answer, because certification is compulsory to touch the equipment.

Two things drive it. Breadth of code: SIC 43220 is a plumbing bucket with air conditioning attached to the end of its name, so filtering on it returns mostly plumbers, and lead lists widen that further by adding directory entries and duplicates. And legal form: Companies House holds only incorporated businesses, so no register-based count — including this one — can see a sole trader with a van. That tail is real but unmeasurable from here, and it is one more reason to read 3,849 as a floor.

The 7,500 F-gas figure is the closest thing to an answer. Anyone installing or servicing this equipment must hold that certification, so it is the only count here tied to a legal obligation rather than a self-declared code — and it counts sole traders and partnerships as well as companies.

What that method catches, it catches accurately — every company in the set advertises cooling or ventilation work in its own trading name, and a hand check found fewer than one wrong match in a hundred. What it misses, it misses completely: a general contractor fitting air conditioning under a plain surname is invisible to it. Only 1,768 of the 3,849 carry an official trade code that mentions air conditioning at all, and they are scattered across more than twenty different activity classes. So 3,849 is a floor on the number of specialists, not a headcount of the whole sector.

What sits inside that floor is small. The typical company turns over £195,000 and employs two people. Three quarters employ four or fewer. Just 28 companies turn over more than £10m. Across the 3,472 that report a figure, these companies employ 24,199 people between them — against roughly 40,000 service technicians in the wider refrigeration and air-conditioning service sector on DEFRA's estimate, published by the industry board ACRIB, and 204,000 employees in the plumbing, heating and air-conditioning installation industry as a whole.

Half of it is one person. 49.8% have a single individual owner; 56.5% have exactly one director; 27.5% are family businesses in which two or more directors or owners share a surname. The typical company is 9.5 years old, about eighteen months older than the average British business. This is a settled, long-established, highly fragmented trade — not a start-up wave.

Profits up, headcount flat

The single most useful thing here is not the growth. It is what the growth did not come with.

Almost none of these companies publish a turnover figure. Small and micro-entity accounts are not required to carry one, and only 84 of the 3,849 ever have. That is why almost every revenue figure published about this trade — including most in this article — is an estimate rather than a reported number.

What every company must file, however small, is what the business owns, is owed and holds in cash. Where the same company can be compared with itself two years apart on the same measure, the change can be read directly rather than inferred from the sector.

941 companies can be compared that way on EBITDA — 24.4% of the trade, and between 254 and 941 depending on the measure. Read it as what it is: the companies we can measure twice are the larger end of the trade, so this describes the measurable quarter rather than all 3,849. The direction is consistent across six independent measures, which is what makes it worth showing.

The median company's headcount was unchanged, and 52.9% of companies reported exactly the same number of staff two years apart.
Source: ExitRadar / Companies House · cohort measured 22 August 2026 — Revenue and EBITDA are ESTIMATED for the majority of these companies, so read this as a change in the measured figure rather than in a reported one. Each measure compares the same company with itself across two accounting periods, so none of it is a segment median or a cross-sectional comparison. The sample differs per measure because a company has to carry the same line in both periods to appear in it, which is why the count is a column rather than a footnote. The companies that can be measured twice are the larger end of the trade. Employees is the only measure that fell.

EBITDA — a measure of trading profit — rose 23.8% in two years across the companies that published it in both periods. Total assets rose 20.6%. Trade debtors, the money customers owe and the nearest thing to a sales figure in accounts this small, rose 20.7%, and that detail matters: it means the growth is real trading, not assets being marked up on paper. Over the same two years the total number of people employed fell 14.6%, the median company's headcount was unchanged, and 52.9% of companies reported exactly the same number of staff two years apart. Fixed assets — vans, tools, plant — were flat at the median. These firms are not building capacity. They are running the capacity they already have harder.

That is a trade charging more because it cannot do more. The evidence on why is not subtle.

The Institute of Refrigeration's workforce study, published February 2026 on a survey of its members taken the previous October, found that 59% of employers were finding it harder to hire engineers than three years ago, while 73% expected demand for them to keep rising. Its central finding was about age: the workforce bunches between 45 and 60, with a "missing middle" where the 25-to-40-year-olds should be. (The survey drew 54 responses — small, and worth saying so.) An apprenticeship study published in June 2026 counted 150 job openings for every apprentice who qualifies as a refrigeration engineer — and only one apprentice in five finishes the course. A 2023 government survey found two-thirds of UK installers were already over 45.

Prices moved accordingly. The BCIS index of building maintenance prices rose 5.4% in the year to March 2026, up from 3.3% the year before, and is forecast to rise another 15.7% over five years — its chief economist naming labour as "the dominant pressure". The national pay agreement for plumbing and mechanical trades locked in 3.4% for 2026 and another 3.4% for 2027. Meanwhile the ONS measure of repair and maintenance work actually carried out did not grow at all in June 2026. Costs up, volume flat: that is what a bottleneck looks like in the numbers.

Three clocks now running

Underneath the weather sit three government deadlines. Each one turns equipment that is already installed and working into equipment that will have to be changed — and by law, only a certificated engineer can do that work.

The gas inside the equipment is being rationed

Every air conditioner, chiller and refrigeration system runs on a working fluid — a refrigerant — and most of what is installed across Britain today uses gases that are potent greenhouse agents. The government does not ban them outright. It rations them: a fixed quantity may be sold into Great Britain each year, and that quantity is cut on a published schedule until the gases price themselves out of use. Northern Ireland follows the tighter European version of the same scheme; England, Scotland and Wales do not.

The ration has been level since 2024. On 1 January 2027 it falls by just under a quarter in a single step. DEFRA consulted in late 2025 on cutting deeper still and, in May 2026, decided not to legislate this year — so the 2027 step stands exactly as already written into law.

Wholesalers have already repriced. Beijer Ref UK, the country's largest refrigeration and air-conditioning distributor, raised prices on 20 May 2026: the two refrigerants sitting in most existing equipment went up 60%, a third by 35%, and even the newer low-impact replacement gas by 30%. Across the EU the same refrigerants had been drifting down 3% a year earlier. This is a British rationing effect, not a world shortage.

A second deadline sits behind it. Since 2020, the most damaging refrigerants — the kind common in older supermarket and cold-store systems — cannot be used to top up a large installation if the gas is newly manufactured; only recycled stock is allowed, and that permission ends in 2030. Every business still running equipment built for those gases therefore has a date by which it must convert or replace. Both jobs are legally restricted to a certificated engineer.

The first UK subsidy pointed at cooling

The Warm Homes Plan, published January 2026, commits £15bn over the Parliament. Buried in it is something the air-conditioning trade has waited a long time for: the Boiler Upgrade Scheme now pays £2,500 for an air-to-air heat pump — equipment the plan itself describes as "able to provide cooling". It is the first time British public money has been directed at kit that cools.

The gate on that money is refrigeration skill. Under MCS's April 2026 rules, an installation business doing this work must put a supervisor in charge who is qualified to Level 3 in refrigeration and air conditioning — the trade certificate held by the companies in this article. A government heating policy now runs through a refrigeration qualification.

And one clock that stopped

Two things widely believed about this market are no longer true, and a serious buyer should know both. The energy-efficiency rating that commercially let buildings were due to reach by 2027 has been dropped. The June 2026 decision replaces it with a higher rating by 2031, applying only to privately rented commercial buildings over 1,000m², and landlords keep the existing get-out where the work would not pay for itself within seven years. Europe has gone further than rationing: it has set dates after which particular types of cooling equipment simply cannot be sold. Britain has not copied that. Those bans apply in Northern Ireland only. So on this side of the Irish Sea, what forces equipment to be replaced is the price and scarcity of the gas — not the kit itself being outlawed.

Meanwhile the heat pump story is going backwards. Certified heat pump installations in the first half of 2026 ran 17% below the same period in 2025 — the only major technology falling, inside a record 210,000 certified renewable installations of all kinds. Around three quarters of those installations only happen because a grant pays for part of them. The government wants 600,000 a year by 2028. In 2025 it got just over 60,000.

The consolidation ladder

This trade is not evenly fragmented. It is fragmented at the bottom and bought up at the top, and the switch happens over a remarkably narrow band of size.

Source: ExitRadar / Companies House · cohort measured 22 August 2026 — Ownership is the public register of people with significant control. The size bands are ESTIMATED revenue, so the base is the 2,419 companies that can be sized at all, not the whole cohort — a company with no revenue figure is in no band. Estimated revenue places a company in a band; it is never used to describe an individual company.

Corporate ownership runs at 3.4% below £250,000 of revenue, 9.3% between £250,000 and £1m, 26.4% between £1m and £5m, and 57.4% above £5m.

The money follows the same line. The 357 company-owned businesses are 9.3% of the trade but hold 39.6% of its measurable revenue — £915m out of £2.31bn. The typical one turns over £1,487,000. The typical independent turns over £170,000. That is a gap of nearly nine times.

And yet nobody is rolling it up. Of the 337 companies that appear as owners on the public ownership register, only 23 own more than one business in this trade, covering 54 between them. The biggest owns 4. Overseas money is barely present either: just 3.0% have a foreign owner, amounting to a handful of Japanese, Swedish, Danish, Belgian, Irish and Australian parents.

Source: ExitRadar / Companies House · cohort measured 22 August 2026 — The two series are different kinds of event and are never added together. A notification is a filing — a company telling the register it now has a corporate owner. A detected change is our own reading of the register moving. Neither is a count of completed transactions, because a share sale is not itself a filing event.

Against the wider market, that reads as early rather than finished. Britain's building-services and property-maintenance sector saw 181 businesses change hands in 2025, up 54% on 2024. Private equity did half of them, and more than four in five of those were small firms folded into a larger group rather than new platforms being built from scratch. Mitie absorbed Marlowe for £366.4m; Sureserve, itself taken private by Cap10 in 2023, bought Kinovo for £56.4m and then made its eighth add-on and first international acquisition in November 2025. And when Rockpool sold Mecsia — a building-services group assembled from smaller firms and taken from £15m to over £100m of revenue in about three years — it returned seven times the money its investors had put in.

In refrigeration specifically, the visible active buyer is Nordic Climate Group, backed by Altor: roughly €600m of revenue and 2,300 employees group-wide, with UK and Ireland operations now past €80m. It has bought ten UK businesses since November 2025, the most recent in July 2026. One of them, MC Refrigeration in Wellingborough, was founded in 2004 by a husband and wife and was being run by their daughter — which is, in a sentence, the transaction this whole article is about.

For scale, look at the United States, where the same trade was consolidated a decade earlier. There are over 126,000 privately owned US HVAC companies, and private-equity and venture-backed businesses still account for only about 8% of industry employment. Apex Service Partners, founded by Alpine Investors in 2019, now runs 75 brands and 13,000 employees on more than $3bn of revenue; Apollo took a minority stake in May 2026. US HVAC services multiples have normalised from a 13.3× average across 2021–2023 to 9.5× across 2024 to date — and new platform formation is contracting even as bolt-on activity continues. No US platform has entered the UK. On the evidence available, nobody has.

The succession story is refrigeration

Against British business as a whole, this trade is not unusually old. Against the trade it is normally counted inside, it is half again as old — and one part of it carries almost all the pressure.

Source: ExitRadar / Companies House · cohort measured 22 August 2026 · classifier ac-v1 — The measure is the OLDEST serving director, not the average age of the board. ExitRadar’s sector pages use the average and will always report a smaller number than this — the two are different measures and must not be cross-quoted. This is the director register: it describes who RUNS these companies, not who owns them.

At 30.7%, cooling and refrigeration sits slightly below the national rate of 32.5%. That is the honest reading, and any analysis telling you this trade is an age outlier against British business as a whole is overselling it. The comparison that matters is with the classification it usually disappears into: plumbing and heating runs at 20.3%. The cooling specialists are half again as old as the plumbers they are filed beside.

And inside the trade, refrigeration is the story. 40.1% of refrigeration companies have a director aged 60 or over, and 12.2% have one past 70 — against 28.0% for air conditioning, 27.7% for ventilation, and just 18.3% for companies that call themselves "HVAC", a naming convention that arrived later and brought younger owners with it.

Source: ExitRadar / Companies House · cohort measured 22 August 2026 · classifier ac-v1 — Growth is the typical two-year change in ESTIMATED revenue for the segment, which shows a direction of travel rather than a precise figure and is never used to describe an individual company. Director age is the oldest serving director. Margin is median EBITDA as a share of revenue; the growth and margin sub-samples are smaller than the company counts beside them.

Refrigeration is simultaneously the oldest segment, the second largest, and the fastest growing — a median +11.8% over two years on estimated revenue, against +2.9% for air conditioning. It also earns the thinnest margin in this trade: a median EBITDA margin of 5.5%, against 11.9% for those calling themselves HVAC. That combination — old owners, growing book, compressed margin, essential service — is precisely the profile a disciplined buyer is looking for, because the margin is where the operating improvement lives.

The older the owner, the bigger the business

A common assumption about ageing owners is that they are winding down. In this trade, the opposite is measurable.

A business owned by another company has no individual owner and appears in no band here at all. Revenue is ESTIMATED, not reported.

The typical company's revenue climbs from £124,500 where the oldest owner is in their thirties to £279,500 where the oldest owner is past seventy — more than double, and it rises at every single step. 44.2% of all the revenue this study can measure sits with owners aged 60 or over — 945 companies, carrying £637m between them.

Length of service tells the same story. The typical director has been in post 7.9 years; 27.6% of companies have one who has served fifteen years or more, and 635 have one past twenty. Apply the profile most buyers actually look for — one director, aged 60 to 70, fifteen years or more in the chair, more than £50,000 of assets behind them — and 107 companies fit it. Open it to anyone over 60 and it is 134.

The regional pattern underneath this is the most quietly interesting thing in the dataset, because it holds everywhere.

Cells holding fewer than 12 companies are left uncoloured and their family share is not reported. A family business is one in which two or more directors or owners share a surname.
Source: ExitRadar / Companies House · cohort measured 22 August 2026 — Ownership register; 3,343 companies with an individual owner’s age on file. This is not a map of company ownership: a business owned by another company has no individual owner and so appears in no age band at all. Revenue is ESTIMATED.

Read left to right along any row and the fill deepens. In London, family-business share runs from 8.3% where the oldest owner is 30–40 to 42.9% where the owner is over 70. In Scotland, 15.8% to 81.3%. In the East of England, 14.5% to 73.1%. And the circles grow as they darken: the largest revenue pools in the country sit in the 50–60 and 60–70 columns, not the young ones.

That is what a succession market looks like before it clears. A business built by one person acquires family members as its owner ages, accumulates value, and then arrives at a handover that has to be resolved one way or another — internally, by sale, or by closure.

Geographically the trade is southern-weighted — London plus the South East is 33.6% of companies, which is what you would expect of a cooling trade tracking commercial density and the hottest part of the country. But the money does not sit where the companies sit.

The revenue pool here totals £1.44bn — the portion attributable to companies with an individual owner age on file, so it is narrower than the £2.3bn cohort total. Succession pressure does not follow volume: the South West runs the highest 60-plus director rate in the country at 39.3%, London the lowest at 25.9%. 3 companies have no mappable registered-office postcode and appear in no row, so the counts sum to slightly less than the cohort while the share column is a share of all of it.
Source: ExitRadar / Companies House · cohort measured 22 August 2026 — Region is the registered office, which for a small trading company is normally where it operates but for a larger one may be an accountant’s address. Revenue is ESTIMATED. The director-age column is the oldest serving director and comes from the director register, not the ownership register.

London holds the most companies but the South East holds much the largest revenue pool — £316.1m against London's £153.7m on almost identical company counts. And the succession pressure is not where the volume is: the South West runs the highest 60-plus director rate in the country at 39.3%, followed by Scotland at 35.3% and the West Midlands at 33.9%. London is the youngest region in this trade at 25.9%.

What is actually buyable

Everything above describes an opportunity. This section describes how small the door is.

Only 84 of the 3,849 have ever FILED a revenue figure — one in forty-five; the rest of the revenue coverage is estimated. Median EBITDA across the measurable set is £32,092, and 29 companies clear £1m.
Source: ExitRadar / Companies House · cohort measured 22 August 2026 — Every row is a share of the SAME base, and the rows are NOT nested: revenue is estimated from balance-sheet features, so a company that filed a balance sheet and no employee count has a revenue figure and no headcount. A company has no EBITDA figure — filed or estimated — for one of four reasons: no readable accounts on file, dormant accounts, no accounts filed at all, or total assets below £NaN, which is the floor of the routine scoring run. That last one is a coverage threshold, not a judgement about the business: most of what sits below it is one- and two-person companies. PURSUE is deliberately not a row here — it is scored on business quality and exit timing and is size-agnostic above a £25,000 floor, so it is not a subset of the band and cannot sit in this flow.

Start with what these companies actually publish. Only 84 of the 3,849 — one in forty-five — have ever filed a revenue figure at all. Everything else is missing or estimated. Of the 3,849, 3,472 report a staff number, 2,419 can be given a revenue estimate, and 1,972 have a usable profit figure.

Of those, 187 sit between £250,000 and £5m of EBITDA — the range a first-time buyer or a small fund can realistically finance. Median EBITDA across the measurable set is £32,092. Only 29 clear £1m.

At the sharp end, 31 companies currently carry a PURSUE label — the top of ExitRadar's acquisition score, each one then put through an automated quality check on the underlying business. That 31 is not a subset of the 187. The label is scored on business quality and exit timing and is deliberately size-agnostic above a £25,000 floor — a strong £60,000-EBITDA business earns it, and sits well below the financeable band. The two are different questions: one asks whether a business is worth approaching, the other whether a first-time buyer could fund it. They carry £71.6m of revenue between them: eleven in refrigeration, eleven in air conditioning and cooling, eight in ventilation, one HVAC-named. That is 0.81% of the trade, against 0.46% for the wider plumbing and heating sector. Roughly one and a half times the hit rate of the trade next door. Our scoring methodology explains how a company earns that label.

What the size gradient is worth

Businesses are priced as a multiple of EBITDA, and no British adviser publishes a multiple specifically for cooling and refrigeration — anyone quoting you one is quoting a guess. What is published, from a survey of 106 UK and Irish advisory firms covering the second half of 2025, is the shape of the curve: mid-market businesses change hands at an average of 5.4× EBITDA, but a business on £200,000 of EBITDA fetches 3.3× while one on £10m fetches 8.4×.

That spread is the whole economic case for buying several small firms and running them as one: the same EBITDA is worth more once it sits inside a bigger business. It is also why 57.4% of the £5m-plus firms have already been bought while 96.6% of the smallest have not. Exhibit 3 is not a description of the past. It is a price list.

What it adds up to

Four things are true at once, and they do not usually come together.

Demand is being structurally repriced. Britain has almost no installed cooling base — 4.3% of homes — in a country the Climate Change Committee expects to see 92% of its existing homes overheating by 2050, with no national cooling plan and, for the first time, public subsidy pointed at equipment that cools.

Supply cannot flex. The trade grew profits 23.8% in two years without the typical firm hiring anyone, on a workforce with a hole where its 25-to-40-year-olds should be and 150 job openings for every apprentice who qualifies.

The regulatory clock forces replacement. The refrigerant ration is cut by almost a quarter on 1 January 2027, and the wholesale price of the gas inside most existing equipment has already risen 60% — and the certificate needed to touch any of it is held by the same shrinking group of engineers.

And the trade has not been bought. 23 corporate owners hold more than one company between them. The largest holds 4. Nobody is buying this up at scale — in a market where a business on £10m of EBITDA is priced at two and a half times the multiple of one on £200,000.

What stands in the way is not opportunity. It is finding the companies. 187 sit in a financeable EBITDA range. 31 are at the top of the acquisition grade — a different cut, not a subset of the first. And roughly 98% of the register files too little to judge without going and looking.

Who's who in this article

Every organisation and term used above, in plain terms.

Met Office
The UK’s national weather and climate service. It sets the official record for temperature, rainfall and sunshine, and its provisional seasonal statistics are what confirm a record.
UK Health Security Agency (UKHSA)
The government agency responsible for protecting public health. It issues the heat-health alerts and publishes the official count of heat-related deaths.
Climate Change Committee
An independent body created by Parliament under the Climate Change Act 2008 to advise the government on climate targets and on preparing the country for a warmer climate. Its advice is not binding, but ministers must respond to it.
DESNZ
The Department for Energy Security and Net Zero — the department responsible for energy policy, home heating and the grants that pay for it.
DEFRA
The Department for Environment, Food and Rural Affairs — the department that sets the rules on refrigerant gases.
ONS
The Office for National Statistics, the UK’s official statistics agency. Its construction figures measure how much building and maintenance work is actually carried out, as opposed to how much it costs.
House of Commons Library
Parliament’s independent research service, which writes impartial briefings for MPs.
Grantham Research Institute
A climate economics research centre at the London School of Economics. It produced the estimate of what the June heatwave cost the economy, with the CMCC, an Italian climate research centre.
English Housing Survey
The government’s annual survey of the condition and occupancy of English homes — the source for how many have air conditioning.
Companies House
The UK’s official register of companies. Every limited company must file its accounts, directors and owners there, and the whole register is public. It is the source for every figure on this page marked ExitRadar.
Public ownership register
Formally the register of “people with significant control”. Companies must name whoever ultimately owns or controls them — a person or another company. It is how this study tells an independent business from one already owned by a group.
Cold Chain Federation
The trade body for the refrigerated storage and transport industry that keeps food and medicine cold between factory and shelf.
Institute of Refrigeration
The professional body for refrigeration and air-conditioning engineers, and the source of the workforce survey quoted here.
ACRIB
The Air Conditioning and Refrigeration Industry Board, which speaks for the trade as a whole and publishes the government’s estimate of how many technicians work in it.
MCS
The Microgeneration Certification Scheme — the body that sets standards for heat pump and solar installers. A government grant is only payable if the installer is MCS certified.
Boiler Upgrade Scheme
The grant that pays households towards replacing a boiler with a heat pump. From 2026 it also covers air-to-air heat pumps, which cool as well as heat.
Warm Homes Plan
The government’s £15bn programme, published January 2026, for upgrading the energy efficiency and heating of British homes over this Parliament.
BCIS
The Building Cost Information Service, part of the Royal Institution of Chartered Surveyors, which publishes the standard indexes of UK construction and maintenance costs.
Beijer Ref
The largest wholesaler of refrigeration and air-conditioning equipment and gases in the UK. What it charges sets the price the trade pays.
Nordic Climate Group
A Swedish-owned group, backed by the private equity firm Altor, that has been buying British refrigeration companies since late 2025 — the most active consolidator in this trade.
EBITDA
Earnings before interest, tax, depreciation and amortisation — a company’s trading profit before financing and accounting charges are taken off. It is the standard measure buyers price a business on, because it strips out decisions made by the current owner (how much debt they took on, how fast they wrote assets down) and shows what the underlying operation earns.
EBITDA margin
EBITDA as a percentage of revenue. A thin margin on a growing book is often what a buyer is looking for: it is the part of the business an operator can improve.
Trade debtors
Money customers owe the business for work already done. In accounts too small to publish a revenue figure, it is the closest available proxy for how much trading is going on.
Median
The middle value: half the companies sit above it, half below. Used throughout in preference to the average, which a handful of large firms would otherwise distort.
PURSUE
ExitRadar’s top acquisition grade. A company earns it by scoring highly on business quality and on the signals that suggest an owner may be ready to sell, and then passing an automated check on the underlying business. It is recalculated as new filings arrive.

Sources and methodology

Figures derive from three categories of source. ExitRadar's proprietary database supplies every register-derived figure, built from Companies House bulk products with ExitRadar's own activity classification, revenue estimation and acquisition scoring applied on top. Official statistics — Met Office, UKHSA, ONS, DEFRA, DESNZ, MHCLG, Ofgem and the House of Commons Library — supply the meteorological, regulatory and macroeconomic figures. Published research and industry data from named trade bodies, certification schemes and advisory firms supplies the market-behaviour figures the register cannot, and is attributed at the point of use; where a figure is a commercial market estimate rather than an official statistic, the text says so.

This article's register figures are a dated snapshot, not a live feed. The cohort is defined by company NAME rather than by industry code, so it is not one of the cuts ExitRadar refreshes weekly, and every figure on this page was measured once — on 22 August 2026, under activity classifier ac-v1. Each exhibit carries that date rather than a rolling "as of" stamp, and the article does not claim a freshness it does not have. The figure most likely to have moved since is the PURSUE count: it is a live label, recomputed as new filings land.

Succession comparisons use the oldest serving director throughout, a different and larger measure than the average-director basis used on ExitRadar's sector pages — the two are not interchangeable and should not be quoted against each other. Owner ages are taken from the register of people with significant control. Turnover, except where explicitly noted as filed, is modelled per filed period and carries confidence bands: 62.1% of estimates are MEDIUM confidence and 32.6% LOW. Growth on filed figures is trimmed at ±300%; growth on estimated revenue shows direction only.

Every chart on this page is drawn from the data table published beside it, so the numbers are readable with or without JavaScript. Nothing here is investment advice, and no company referenced is being offered for sale.
