Availability confirmed from postcode and system details
For an existing system that is not heating or producing hot water correctly, repair work should first establish the symptom and system details: make and model, error code, heating and hot-water behaviour, pressure or flow indications, recent electrical or plumbing changes, and whether the outdoor unit is obstructed or exposed to unusual debris or weather. Diagnosis may cover controls and sensors, power and communications, water-side circulation, filters and strainers, defrost behaviour, refrigerant-side faults by appropriately qualified personnel, and condensate drainage. Repair is distinct from a new installation: the aim is to identify and remedy the fault safely, explain any parts or follow-on work required, and only recommend replacement when condition, compatibility or economics justify it. Coastal exposure, access constraints in dense historic streets, and flood-related site considerations should be recorded as part of the visit brief without assuming a fault or service outcome.

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.
The council’s home-energy assistance page says its Warm Homes: Local Grant may include an air-source heat pump as well as insulation and solar PV, subject to published eligibility conditions. It also describes separate advice and finance routes. Confirm current eligibility directly with the council or named programme partner.
Record the postcode, system make and model, visible error codes, affected services, recent changes and photographs of the controls and outdoor unit. Do not remove refrigerant components or bypass safety controls; provide the information so the diagnosis can be planned safely.
