Heat pump servicing in Sutton: what to expect
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.
Service visits in Sutton include unvented cylinder safety checks alongside the heat pump itself. If a heat pump in Sutton has not been serviced for a while, the first visit includes a full check of settings and pressures.
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
- Homes where running costs have crept up or rooms feel cooler than before
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Expansion vessel, pressure relief and water quality checks
- Magnetic filter and strainer clean, with system pressure topped up
- A dated service record for your warranty and property files
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Controls and error log check, with settings adjusted where needed
Homes in Sutton and across Greater London can book servicing at a time of year that suits them, ideally before winter.
Grants and rules for heat pumps in England
Homes in Sutton 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.

How long is the heating season in Sutton?

Heat pump servicing in Sutton: questions
How much does a visit cost in Sutton?
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.
How often should a heat pump in Sutton be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
What should I check before booking a visit in Sutton?
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 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.
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.
