Heat pump repairs in Chorley: what to expect
Whoever installed your heat pump, aftercare can be arranged in Chorley. 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 Chorley and Lancashire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. For repeated faults in Chorley, 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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps showing an error code or fault light
- Heat pumps installed by another company that need a second opinion
What's included
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
We repair heat pumps in Chorley 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 Chorley quote.

How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
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.
