What to know about heat pump servicing in Barnes
Aftercare matters as much as installation. For a heat pump in Barnes the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
Homes in Barnes and across Greater London can book servicing at a time of year that suits them, ideally before winter. Heat pumps in Barnes that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
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 a year or more past installation
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Glycol or antifreeze protection test where fitted
- Unvented cylinder safety checks and legionella cycle check
- Expansion vessel, pressure relief and water quality checks
- Magnetic filter and strainer clean, with system pressure topped up
- Controls and error log check, with settings adjusted where needed
Service visits in Barnes include unvented cylinder safety checks alongside the heat pump itself.
Grants and rules for heat pumps in England
Homes in Barnes 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 in Barnes: questions
What should I check before booking a visit in Barnes?
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 visit cost in Barnes?
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.
Do you also cover Putney?
Yes. We arrange heat pump servicing and repairs in Putney, which is about a mile south-east of Barnes, and across Greater London.
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.
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.
