UK HVAC Market Report: Business Sales Outlook 2026

For HVAC business owners considering a sale, understanding the market conditions is essential. The UK heating, ventilation, and air conditioning sector is in a period of structural change: the heat pump transition is accelerating, private equity consolidation is intensifying, and a looming tax change is compressing the timeline for sellers. This report examines the factors that matter most to anyone evaluating their options in 2026.

Market Size and Growth

The UK HVAC market continues to expand at a pace that exceeds most other building services sectors. Industry projections put the compound annual growth rate at 3.89% from 2026 through 2031, driven by new-build housing requirements, retrofit demand, and the ongoing shift from gas to electric heating. The services segment, which includes maintenance, repair, and installation, is growing faster still at an estimated 7.55% CAGR, reflecting the increasing value of ongoing service relationships over one-off project work.

For business owners, this growth trajectory matters because it directly supports valuations. Acquirers are not buying today's revenue alone; they are buying access to a market with visible, policy-backed demand for the next decade. This is why HVAC multiples have remained robust even as other sectors have seen valuation compression.

The Heat Pump Transition

The government's Clean Heat Market Mechanism (CHMM) requires boiler manufacturers to ensure that heat pumps constitute at least 6% of their annual sales from 2025 onwards. This target is expected to increase year on year, creating a sustained ramp in demand for qualified heat pump installers. The Boiler Upgrade Scheme, which provides homeowners with grants of up to £7,500 toward heat pump installation, is further accelerating consumer adoption.

For HVAC business owners, this creates a strategic decision point. Retraining each engineer costs between £3,000 and £5,000, and MCS accreditation requires investment in quality management systems, equipment, and ongoing compliance. Some owners are choosing to invest and position for growth. Others are choosing to sell while their Gas Safe workforce is at peak value, before transition costs erode margins. What matters is making the decision deliberately, with a clear understanding of what your business is worth today.

Owner Demographics and Exit Timing

A significant proportion of UK HVAC business owners are approaching retirement age, having built their companies during the expansion of domestic gas central heating in the 1990s and 2000s. These owners face a convergence of personal readiness to exit, workforce succession needs, and a regulatory environment demanding ongoing investment. The result is rising supply of quality businesses, which is attracting more buyers. Both supply and demand are elevated simultaneously, keeping transaction volumes high without depressing prices.

Acquisition Activity

Private equity activity in the UK HVAC sector has reached levels not seen in previous cycles. Buy-and-build strategies are the dominant model: a PE firm acquires a platform business, then bolts on smaller firms to fill geographic gaps, add specialist capabilities such as heat pump installation, or bring in certified engineers.

This means HVAC businesses of almost every size are in demand. Larger firms (£2m+ turnover) attract interest as platforms; smaller firms (£500k to £2m) are sought as bolt-ons. Trade buyers remain active alongside PE, using acquisitions to enter the heat pump market, add F-Gas capability, or strengthen maintenance contract books. This buyer competition is supporting valuations and giving sellers a stronger negotiating position than they might expect.

Valuation Trends

HVAC business valuations in 2026 are being shaped by several intersecting factors:

• Recurring revenue premium: maintenance and service contract income is being valued at 2x to 3x annual revenue, reflecting high renewal rates and the strategic importance of ongoing client relationships
• Certification uplift: businesses with Gas Safe, F-Gas, and MCS accreditation consistently achieve higher multiples than those without, as these certifications are time-consuming and expensive for buyers to obtain independently
• Engineer value: each qualified Gas Safe or F-Gas engineer effectively adds a quantifiable premium to the business value, given the chronic skills shortage across the sector
• Heat pump positioning: businesses with demonstrated heat pump installation capability and an MCS-accredited pipeline are attracting competing offers from buyers who see the low-carbon transition as a growth catalyst

Overall EBITDA multiples for the sector remain in the 3x to 6x range, with the strongest businesses, those combining recurring revenue, a certified workforce, and heat pump capability, reaching the upper end.

BADR Tax: The April 2026 Deadline

Business Asset Disposal Relief (BADR) allows qualifying business owners to pay a reduced rate of Capital Gains Tax on the first £1 million of lifetime gains. The BADR rate is currently 14%, but it rises to 18% from April 2026, on its way to matching the standard CGT rate of 24%.

For an HVAC business owner selling at a gain of £800,000, the difference between 14% and 18% is £32,000 in additional tax. That figure is creating urgency among owners who were previously content to wait. BADR qualifying conditions must be met for at least two years before the sale, so owners who have not yet started the process should seek professional tax advice alongside their sale planning.

Outlook for Sellers

The combination of strong market growth, active PE consolidation, the heat pump transition premium, and the BADR tax incentive makes 2026 a favourable window for HVAC business owners considering a sale. Valuation still depends on the fundamentals: the quality of your earnings, the depth of your contract book, the stability of your workforce, and the degree to which the business can operate without you.

What the external conditions do offer is alignment in your favour. Buyer demand is high, growth projections are policy-backed, and the tax environment rewards decisive action. For owners who have been thinking about their next chapter, this is an observation that the conditions for a strong outcome are, at this moment, as good as they have been.
