Before you book: heat pump repairs in Woking
Aftercare matters as much as installation. For a heat pump in Woking 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.
Heat pump owners in Woking can arrange a fault-finding visit at a rate agreed before an engineer attends. Across Woking and Surrey, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps installed by another company that need a second opinion
- Heat pumps showing an error code or fault light
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- System refill, venting and recommissioning after the repair
We repair heat pumps in Woking whoever installed them, including older monobloc and split systems.
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 Woking quote.

Short winter days in Woking and what they mean
On the shortest day Woking gets about 7 hours 51 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- We confirm the fault-finding rate and arrange a visit in Woking.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Woking: questions
How often should a heat pump in Woking 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.
Can you work on a heat pump in Woking that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Woking, whoever fitted them. Tell us the make and model when you get in touch.
How much does a visit cost in Woking?
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 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.
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.
