Before you book: heat pump servicing in Slough
Aftercare matters as much as installation. For a heat pump in Slough 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.
Landlords in Slough can arrange servicing for several properties, with a dated record for each. Heat pumps in Slough 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 installed by another company that need a new servicing arrangement
- Heat pumps a year or more past installation
What's included
- Expansion vessel, pressure relief and water quality checks
- A dated service record for your warranty and property files
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- Unvented cylinder safety checks and legionella cycle check
- Magnetic filter and strainer clean, with system pressure topped up
If a heat pump in Slough has not been serviced for a while, the first visit includes a full check of settings and pressures.
Grants and rules for heat pumps in England
Homes in Slough 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 Slough: questions
What should I check before booking a visit in Slough?
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 Slough?
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 Maidenhead?
Yes. We arrange heat pump servicing and repairs in Maidenhead, which is about 5 miles west of Slough, and across Berkshire.
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.
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.
