What to know about heat pump repairs in Tavistock
Aftercare matters as much as installation. For a heat pump in Tavistock 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 Tavistock that need a part ordered are explained and priced before the engineer leaves. Across Tavistock and Devon, 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.
- Heat pumps installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- Reading of error history and operating data
- System refill, venting and recommissioning after the repair
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
For repeated faults in Tavistock, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in England
Homes in Tavistock can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs in Tavistock: questions
What should I check before booking a visit in Tavistock?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Can you work on a heat pump in Tavistock that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tavistock, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Plymouth?
Yes. We arrange heat pump servicing and repairs in Plymouth, which is about 12 miles south of Tavistock, and across Devon.
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.
