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.
We service heat pumps in Merseyside whoever installed them, including monobloc and split systems. Landlords in Merseyside can arrange servicing for several properties, with a dated record for each. Heat pumps in Merseyside that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
Who it suits
- Homes where running costs have crept up or rooms feel cooler than before
- 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
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.
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.
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.
