Heat pump servicing for Walthamstow 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.
Heat pumps in Walthamstow that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service. Service visits in Walthamstow include unvented cylinder safety checks alongside the heat pump itself.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Heat pumps a year or more past installation
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Unvented cylinder safety checks and legionella cycle check
- Controls and error log check, with settings adjusted where needed
- Cleaning of the outdoor unit coil, fan area and condensate drain
- A dated service record for your warranty and property files
- Magnetic filter and strainer clean, with system pressure topped up
Homes in Walthamstow and across Greater London can book servicing at a time of year that suits them, ideally before winter.

Homes in Walthamstow 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.

Heat pump servicing in Walthamstow: questions
Can you work on a heat pump in Walthamstow that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Walthamstow, whoever fitted them. Tell us the make and model when you get in touch.
How much does a visit cost in Walthamstow?
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.
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 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.
