Typical repairs fall within a guide range of £90–£1,100, including VAT, depending on the part and the time involved. Refrigerant repairs must be done by an F-gas certified engineer. Regular heat pump servicing catches many of these faults before they stop the system working.
Repairs in Gloucestershire that need a part ordered are explained and priced before the engineer leaves. Heat pump owners in Gloucestershire can arrange a fault-finding visit at a rate agreed before an engineer attends. We repair heat pumps in Gloucestershire whoever installed them, including older monobloc and split systems.
Who it suits
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps showing an error code or fault light
- Heat pumps installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
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 quote.

Heat pump repairs questions
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.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
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.
