Heat pump repairs in Marlborough: what to expect
Whoever installed your heat pump, aftercare can be arranged in Marlborough. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around Marlborough can ice more heavily, so siting is checked as part of any icing fault. Heat pump owners in Marlborough can arrange a fault-finding visit at a rate agreed before an engineer attends.
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
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- 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
- Fault-finding visit at a rate agreed before attending
- Refrigerant repairs by an F-gas certified engineer where needed
We repair heat pumps in Marlborough whoever installed them, including older monobloc and split systems.
Grants and rules for heat pumps in England
Homes in Marlborough 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 Marlborough: questions
Can you work on a heat pump in Marlborough that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Marlborough, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Marlborough?
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.
Do you also cover Swindon?
Yes. We arrange heat pump servicing and repairs in Swindon, which is about 10 miles north of Marlborough, and across Wiltshire.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
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.
