What to know about heat pump repairs in Westerham
Whoever installed your heat pump, aftercare can be arranged in Westerham. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Across Westerham and Kent, refrigerant repairs on split systems are carried out by an F-gas certified engineer. For repeated faults in Westerham, the engineer looks at the system design as well as the failed part.
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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
We repair heat pumps in Westerham 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 Westerham quote.

Heat pump repairs in Westerham: questions
How much does a visit cost in Westerham?
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.
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.
Can you work on a heat pump in Westerham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Westerham, whoever fitted them. Tell us the make and model when you get in touch.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
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.
