What to know about heat pump repairs in Hexham
Aftercare matters as much as installation. For a heat pump in Hexham 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.
Heat pump owners in Hexham can arrange a fault-finding visit at a rate agreed before an engineer attends. We repair heat pumps in Hexham whoever installed them, including older monobloc and split systems.
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
- System refill, venting and recommissioning after the repair
- 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
- Refrigerant repairs by an F-gas certified engineer where needed
Across Hexham and Northumberland, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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 Hexham quote.

Heat pump repairs in Hexham: questions
Do you also cover Prudhoe?
Yes. We arrange heat pump servicing and repairs in Prudhoe, which is about 10 miles east of Hexham, and across Northumberland.
Can you work on a heat pump in Hexham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hexham, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
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.
