Heat pump servicing in Hounslow: 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.
Landlords in Hounslow can arrange servicing for several properties, with a dated record for each. Homes in Hounslow and across Greater London can book servicing at a time of year that suits them, ideally before winter.
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
- Landlords who need dated service records for each property
- Homes where running costs have crept up or rooms feel cooler than before
What's included
- Glycol or antifreeze protection test where fitted
- Controls and error log check, with settings adjusted where needed
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- A dated service record for your warranty and property files
- Expansion vessel, pressure relief and water quality checks
Service visits in Hounslow include unvented cylinder safety checks alongside the heat pump itself.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Hounslow quote.

Heat pump servicing in Hounslow: 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.
Do you also cover Twickenham?
Yes. We arrange heat pump servicing and repairs in Twickenham, which is about 2 miles south-east of Hounslow, and across Greater London.
What should I check before booking a visit in Hounslow?
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.
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.
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.
