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.
Service visits in Kent include unvented cylinder safety checks alongside the heat pump itself. We service heat pumps in Kent whoever installed them, including monobloc and split systems. Landlords in Kent can arrange servicing for several properties, with a dated record for each.
Who it suits
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
- Heat pumps a year or more past installation
- Homes where running costs have crept up or rooms feel cooler than before
Grants and rules for heat pumps in England
Homes in Kent can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump servicing questions
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.
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.
