Diagnosis of fault codes, loss of heating or hot water, unusual noise, poor temperature control, circulation problems and water-side pressure or flow issues Inspection of electrical supply, controls, sensors, fans, pumps, valves, pipework and visible leaks before repair decisions are made Repair or replacement recommendations should distinguish between the heat-pump unit, controls, emitters, cylinder and wider wet-heating system Do not reset, open or modify refrigerant circuits unless the work is suitable for a competent qualified professional and the manufacturer requirements are met

Use your postcode, system details and requested support to confirm the appropriate availability and appointment route.
A repair or diagnostic visit is shaped around the reported fault and the system behaviour that can be assessed.
Use the booking form to provide your postcode and choose the support you need. That information is used to confirm the right next step.
These public sources inform the guide. They do not establish service availability or describe work by Heat Pumps Service.
Provide your Cheltenham postcode, heat-pump type, make and model, fault codes, symptoms, affected heating or hot-water functions, and any installation or service records. Photographs of the display and accessible equipment can help, but do not remove covers or interfere with electrical or refrigerant components.
Yes. Cheltenham Borough Council explains that air-to-water systems commonly operate at lower flow temperatures than conventional boilers, so radiator size, underfloor heating, pipework, insulation, heat loss and system controls can affect performance. A competent assessment should consider the whole heating system rather than the outdoor unit alone.
