Frequently asked questions
What's my plumbing/heating business worth?
Most UK plumbing, HVAC and trades businesses sell around 3-5× adjusted profit (SDE). Recurring maintenance contracts, retained engineers and a team that can work without the owner on the tools move you toward the top of that range.
Why does owner-dependency lower the value?
If the owner is still on most call-outs, buyers see key-person risk and a harder handover. That usually means a lower multiple. Building a capable engineer bench and documented jobs reduces dependency and supports a stronger price.
Do maintenance contracts increase the price?
Yes. Recurring service plans are more valuable than one-off emergency work because earnings are easier to forecast. A solid forward book, Gas Safe credentials and low engineer churn further support a higher adjusted-profit multiple.
How do I sell my plumbing or HVAC business in the UK?
Work out what the business earns after paying yourself a market wage, gather three years of accounts, your maintenance contract list, Gas Safe and other accreditations, and an engineer and van schedule, then decide whether to sell privately or with a broker. You can list on Dealdoor for free with no commission on completion, and a broker is optional, so start with the free valuation to set a realistic asking price.
Do I need a broker to sell my HVAC business?
No. A broker can find and screen buyers and manage the process, usually for a fee, but many owners of trades businesses sell directly to a competitor, a key employee or a buyer found through a marketplace. If you want help, ask what the fee covers and whether it is paid only on completion. Dealdoor supports both routes.
