The factors that determine your business value.
HVAC businesses typically achieve 4 to 10x EBITDA for well-positioned operators with recurring contracts and accreditations. EBITDA is, roughly, the yearly profit from day-to-day work before loan interest, tax and wear on vans and kit, and the multiple is the number a buyer multiplies it by to reach a price. Here is what moves that multiple.
How the multiple is calculated
- Base multiple: 4x EBITDA
- Adjusted for business size: larger businesses command higher multiples, smaller ones lower
- +1.5x if recurring service contracts represent more than 40% of revenue
- +1x if F-Gas or REFCOM accreditation held
- +1x if Gas Safe, OFTEC or MCS accreditation held
- +1x if fleet size exceeds 10 vehicles
- +1x if active public sector framework agreements in place
- + up to 1x if the business runs under management rather than the owner on the tools
- Maximum: 10x EBITDA

Maintenance Contracts
Recurring revenue from service contracts is the single most valuable asset in an HVAC business. Buyers pay a premium for predictable, repeating income with high retention rates.
Gas Safe Engineers
The number and quality of Gas Safe registered engineers directly affects capacity and value. Qualified engineers are scarce, and buyers value businesses with a strong, registered workforce.
Heat Pump and MCS Capability
MCS accreditation and active heat pump installation capability signal future-readiness. With the 2035 gas boiler phase-out, buyers pay more for businesses positioned for the transition.
F-Gas Certification
F-Gas certification is essential for any business working with refrigerants and air conditioning. It opens the door to commercial contracts and is increasingly required by larger clients.
Geographic Density
Concentrated customer bases reduce travel time and increase engineer productivity. Route density is a hidden multiplier that acquirers, particularly groups backed by private equity (investment firms that buy companies to grow and sell on), actively look for.
Fleet Condition
Well-maintained, branded vehicles and equipment reduce the buyer's post-acquisition capital expenditure. A modern fleet signals a well-run operation and supports a higher valuation.
Owner Dependency
Businesses that can operate without the owner command significantly higher multiples. If you are on the tools every day and the business cannot function without you, buyers will discount accordingly.
Commercial vs Residential Mix
Commercial contracts tend to be larger, longer-term, and more predictable. A strong commercial client base often supports a higher multiple than purely residential work.
How we work out the figures.
The figures come from industry benchmarks for UK HVAC business sales: the profit multiples that businesses like yours typically sell for. The calculator applies them to the turnover and profit you give it, then adjusts for your other answers.
These benchmarks are published reference ranges, not a record of completed sales, so the result is an indicative range rather than a formal valuation. A formal valuation needs a look at your accounts and how the business runs.
We last reviewed the benchmarks in July 2026.
Your business is worth more than a guess.
"An indicative range is the start of the conversation. What your business is genuinely worth is revealed by real buyer competition, and that is what we create."Simon Read, Founder & Managing Director
