Before you book: heat pump repairs in Calne
Whoever installed your heat pump, aftercare can be arranged in Calne. 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 Calne and Wiltshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. For repeated faults in Calne, 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
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
What's included
- Reading of error history and operating data
- 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
- System refill, venting and recommissioning after the repair
Heat pump owners in Calne can arrange a fault-finding visit at a rate agreed before an engineer attends.
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 Calne quote.

How long is the heating season in Calne?
On the shortest day Calne gets about 7 hours 50 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.
Booking a visit in Calne
- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Calne.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Heat pump repairs in Calne: questions
Do you also cover Chippenham?
Yes. We arrange heat pump servicing and repairs in Chippenham, which is about 5 miles west of Calne, and across Wiltshire.
Can you work on a heat pump in Calne that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Calne, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Calne 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.
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.
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.
