- Heat pumps showing an error code or fault light
- Outdoor units that have become noisy, iced up or keep switching on and off
- Systems losing pressure or needing frequent topping up
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead

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 Gerrards Cross quote.

Heat pump repairs in Gerrards Cross: questions
What should I check before booking a visit in Gerrards Cross?
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.
Can you work on a heat pump in Gerrards Cross that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Gerrards Cross, whoever fitted them. Tell us the make and model when you get in touch.
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.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
