A heat pump service is an annual inspection and maintenance visit that checks the outdoor unit, the heating water circuit, the controls and the hot water cylinder are working safely and efficiently. Heat pumps have no burner or flue to inspect, but they rely on clean water flow, correct pressures and well-set controls, all of which can drift over a year.
Homes in Dorset and across Dorset can book servicing at a time of year that suits them, ideally before winter. Service visits in Dorset include unvented cylinder safety checks alongside the heat pump itself. Landlords in Dorset can arrange servicing for several properties, with a dated record for each.
Who it suits
- Heat pumps installed by another company that need a new servicing arrangement
- Landlords who need dated service records for each property
- Heat pumps a year or more past installation
- Systems where the manufacturer's warranty requires annual servicing
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.

Heat pump servicing questions
Can you service a split system?
Yes. Split systems have refrigerant pipes running between the outdoor unit and an indoor unit, and checks on that refrigerant circuit must be done by an F-gas certified engineer. We arrange the service so a suitably certified engineer attends. The water side, controls and cylinder are checked in the same visit, just as on a monobloc system.
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.
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.
Do I need to do anything between services?
A little. Keep the area around the outdoor unit clear of leaves, snow, plants and stored items so air flows freely. Check the system pressure gauge occasionally if you have one, and note any error codes. Avoid covering the unit or building an enclosure around it without advice, as this can reduce performance.
