Heat pump repairs for Chippenham homes
Aftercare matters as much as installation. For a heat pump in Chippenham 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.
Repairs in Chippenham that need a part ordered are explained and priced before the engineer leaves. For repeated faults in Chippenham, 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
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- Fault-finding visit at a rate agreed before attending
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
Outdoor units in exposed spots around Chippenham can ice more heavily, so siting is checked as part of any icing fault.
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 Chippenham quote.

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