Heat pump servicing for Clapham homes

A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.

If a heat pump in Clapham has not been serviced for a while, the first visit includes a full check of settings and pressures. Landlords in Clapham can arrange servicing for several properties, with a dated record for each.

An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.

  • Systems where the manufacturer's warranty requires annual servicing
  • Heat pumps installed by another company that need a new servicing arrangement
  • Heat pumps a year or more past installation

What's included

  • Controls and error log check, with settings adjusted where needed
  • Expansion vessel, pressure relief and water quality checks
  • Cleaning of the outdoor unit coil, fan area and condensate drain
  • Refrigerant circuit checks on split systems by an F-gas certified engineer
  • Magnetic filter and strainer clean, with system pressure topped up

Homes in Clapham and across Greater London can book servicing at a time of year that suits them, ideally before winter.

Heat pump servicing in Clapham: questions

Will the engineer need access indoors as well as outside?

Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.

How much does a visit cost in Clapham?

The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.

What should I check before booking a visit in Clapham?

Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.

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.

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.
