Who Is Buying UK HVAC Businesses, and What They Screen For

The FieldFour buyers, four reasons, four sets of questions

The backed consolidator is the buyer most owners have not met. These are groups with institutional money behind them, assembling regional coverage out of established firms, and the UK market has a visible example in EARNZ plc, which acquired Cosgrove and Drew and South West Heating Services and was readmitted to AIM in August 2024. Sureserve, taken private and backed by Cap10, added several businesses across 2024 in the same pattern. What these buyers want is engineer headcount, a contracted book and a geography they do not yet cover.

The trade buyer is the competitor two counties over, or the larger firm your customers already know. They buy capability they would otherwise have to build, which in this trade usually means F-Gas certified engineers, MCS accreditation or a commercial client list. They tend to know your market well enough to be sceptical about your numbers, and well enough to pay properly when the numbers hold.

The adjacent acquirer comes from facilities management, energy services or building controls, and wants heating and air conditioning as a line in a broader compliance offering. They are often the least interested in your installation revenue and the most interested in your planned maintenance contracts, because the maintenance book is what sits alongside what they already sell.

The fourth is your own management team, and it is the buyer owners underrate. A management buy-out is slower, usually funded in part out of the business's own future profits, and it almost always produces a lower headline number. It also produces certainty about staff, customers and the name over the door, which for some owners is most of what they wanted.

The ScreenThe four questions that get asked before anybody visits

Contracted proportion is the first screen and it is close to universal. What share of last year's revenue was under a maintenance or service agreement, what share was project work, and what the trend has been across three years. A buyer who cannot answer that from the information memorandum will ask before agreeing to a meeting.

Certified engineer headcount is the second, and it is read as a hard number rather than a description. How many engineers, on the register through your business, holding which F-Gas categories, with what length of service. In a trade where recruitment is the binding constraint, this is the line most acquisition models are actually built on.

Customer concentration is the third, and it is where good businesses lose money in negotiation. One managing agent or one contract representing a third of income is a risk the buyer prices, and no amount of explaining how long the relationship has run changes that. Spread takes years to build and it is worth starting the year you first think about an exit.

Owner dependence is the fourth and the most common discount of all. If every quote, every price decision and every difficult customer runs through you, the buyer is acquiring a job rather than a business, and the offer will reflect it through a longer handover, more deferred consideration or both. It is also the most fixable of the four in a twelve to twenty-four month window.

The ChoiceThe right buyer is not always the highest number

A backed consolidator will usually pay the most and integrate the hardest. Your systems change, your van livery changes eventually, and your long-serving supervisor reports to somebody in another county. That is neither good nor bad on its own, and plenty of owners are content with it, but it is worth deciding how you feel about it before rather than after.

A trade buyer sits in the middle and often keeps more of the business intact, particularly where they are buying a geography rather than a capability. A management buy-out keeps almost everything intact and pays the least, over the longest period, with the most of it dependent on the business continuing to perform.

What all of that means in practice is that the question owners ask first, what is my business worth, has a different answer for each type of buyer. Knowing which buyers your business would actually attract, and why, is a more useful starting point than a single number, and it is the thing worth establishing before anybody is approached.
