UK HVAC and Plumbing Industry: Market Report 2026

The UK heating, ventilation, air conditioning, and plumbing sector is undergoing a generational shift. The energy transition is reshaping what buyers want, an ageing ownership base is creating a steady flow of businesses coming to market, and skilled labour constraints are making established teams more valuable than ever. This report draws on our analysis of UK company registration data to present the sector's current landscape.

Market Size and Structure

Our analysis of UK company data identifies 258,054 active HVAC and plumbing companies operating across the country. The sector encompasses boiler installation and servicing, air conditioning, refrigeration, heat pump installation, plumbing, and gas engineering.

Like many trades-based sectors, the HVAC industry is highly fragmented. The vast majority of businesses are owner-managed operations employing between one and twenty people. Many were built over decades by a single founder who earned their reputation through quality workmanship and local relationships.

Of these companies, 249,415 have identifiable ownership data through registered persons of significant control. This provides a clear view of the sector's ownership demographics and the succession pressures that are beginning to build.

The Ownership Landscape

The ownership profile of the UK HVAC sector reveals a sector approaching a significant wave of ownership transitions.

162,662 HVAC and plumbing companies, representing 63% of the total, have a single controlling owner. These are businesses where one individual holds the majority stake and drives the key decisions. When that person decides to step back, the business faces a binary outcome: sale or closure.

Of those single-owner businesses, 42,611 have an owner aged 60 or over, representing 17% of the sector. Within that cohort, 21,535 are aged 65 or above and 10,190 are aged 70 or over. These owners are either actively planning an exit or will face the question within the next few years.

Our analysis identifies 22,370 HVAC and plumbing businesses that meet the criteria for being "exit-ready": a sole controlling owner aged 60 or above, with no obvious internal succession path. This represents a substantial pool of potential acquisition targets over the medium term.

What This Means for Buyers

For acquirers, whether trade buyers, private equity platforms, or individuals entering the sector, the energy transition is the defining factor shaping acquisition strategy in 2026.

The shift from gas to heat pump technology is creating significant demand for businesses that hold MCS (Microgeneration Certification Scheme) accreditation. An MCS-certified HVAC business is positioned to benefit directly from the government's heat pump rollout, the Boiler Upgrade Scheme, and the Future Homes Standard. Buyers are paying a meaningful premium for this capability because achieving MCS certification from scratch takes considerable time and investment.

Businesses with dual capability, combining Gas Safe registration with heat pump and renewable installation credentials, are the most sought-after targets. These companies can serve both the existing gas boiler maintenance market and the growing heat pump installation market, providing a natural hedge during the transition period.

F-Gas certification is another differentiator. As air conditioning and refrigeration demand grows, partly driven by warming summers and stricter commercial regulations, businesses with F-Gas qualified engineers are well-positioned for long-term growth.

What This Means for Sellers

Demand for HVAC businesses is strong across the board, but particularly so for operators positioned for the energy transition. Indicative valuation multiples currently range from 2.5x to 6x EBITDA, depending on the revenue profile, certifications held, and team quality.

Businesses with a high proportion of recurring maintenance contracts command the strongest multiples. Annual boiler servicing agreements, commercial HVAC maintenance programmes, and landlord gas safety certificate arrangements all represent predictable, renewable income that buyers value highly.

The skilled labour shortage in the HVAC sector makes established teams a strategic asset. Training a Gas Safe engineer takes years, and adding heat pump competency on top of that requires further investment. Buyers are often motivated primarily by acquiring a qualified workforce, with the revenue stream as the secondary consideration. Sellers with stable, qualified teams who are likely to remain post-acquisition are in a particularly strong negotiating position.

For owners who have not yet invested in heat pump or renewable capability, the current market still offers attractive exit opportunities. A well-run gas boiler servicing business with a loyal client base and stable team remains a valuable acquisition target. However, as the transition accelerates, the window for maximising value on a traditional gas-only operation will narrow.

Market Drivers

Several structural forces are shaping the HVAC acquisition market in 2026 and the years ahead.

Future Homes Standard

From 2025, new-build homes in England must produce 75% less carbon than current standards. This effectively mandates low-carbon heating systems in new developments, creating sustained demand for heat pump installation and commissioning.

Boiler Upgrade Scheme

The government's grant programme, currently offering up to £7,500 towards heat pump installation costs, is accelerating consumer adoption. HVAC businesses with MCS accreditation are direct beneficiaries of this scheme, and the pipeline of work it generates makes these businesses more attractive to acquirers.

Net Zero Targets

The UK's legally binding commitment to reach net zero by 2050 underpins long-term demand for low-carbon heating solutions. Commercial and public sector organisations are increasingly required to decarbonise their heating, creating opportunities for HVAC businesses that can deliver on those requirements.

F-Gas Regulation

Tighter restrictions on fluorinated greenhouse gases are driving demand for qualified refrigeration and air conditioning engineers. Businesses with F-Gas certified teams are well-positioned as older systems need replacing with compliant alternatives.

Ageing Workforce

The sector faces a well-documented skills gap. Experienced Gas Safe and MCS-certified engineers are in short supply, and the training pipeline is not producing replacements fast enough. This makes every established team more valuable and reinforces the acquisition-led growth strategy that many buyers are pursuing.

Indicative Valuation Benchmarks

Valuations in the HVAC sector vary considerably depending on the nature of the business. The following benchmarks are indicative and based on current market activity. A formal valuation should always reflect the specific circumstances of the individual operation.

2.5x to 4x EBITDA

Typical for project-heavy businesses where the majority of revenue comes from one-off installation work, whether new boiler installations, bathroom refits, or commercial fit-outs. The lower predictability of future income results in a more conservative multiple.

3x to 5x EBITDA

Achievable for businesses with a moderate proportion of recurring revenue from maintenance contracts, combined with installation and project work. Some accreditations (Gas Safe, F-Gas) and a stable team will support this range.

4x to 6x EBITDA

Reserved for businesses with high recurring revenue, dual certification (Gas Safe plus MCS or F-Gas), an established management team, and a diversified client base across domestic and commercial work. These are the premium targets that attract competitive interest from multiple buyers.

These ranges are indicative only and should not be treated as a guaranteed outcome. The actual value of any business depends on its specific financial performance, client concentration, team stability, certification status, and a range of other factors that a detailed valuation will assess.
