Annual servicing is recommended for all heat pumps, and many manufacturers make it a condition of their warranty. A service record also helps if you sell the home or need to make a warranty claim. The service is a paid visit with a guide price of £120–£250, including VAT, and the price for your system is confirmed when you book.

Heat pump servicing questions
What does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
How much does a heat pump service cost?
An annual heat pump service has a guide price of £120–£250, including VAT. Where your price sits depends on the type of system, whether it is a split system needing refrigerant checks and whether an unvented cylinder is included. Any parts or repairs found during the service are explained and priced before any work goes ahead.
How often should a heat pump be serviced?
Once a year is the usual recommendation for air source heat pumps, and many manufacturers require it as a warranty condition. An annual visit cleans filters and strainers, checks pressures and controls, and tests the unvented cylinder's safety devices. If you notice a drop in performance, unusual noises or repeated error codes between services, arrange a visit sooner.
Is servicing needed to keep my warranty valid?
Often, yes. Many manufacturer warranties require an annual service with a dated record, and some extended warranties require an approved installer. Manufacturer warranties pass to you, and the length depends on the make and model. Check your warranty documents, and keep every service record safe with your MCS certificate and handover pack.
