Repair triage should distinguish controls or sensor issues from circulation, defrost, condensate, electrical and refrigerant faults. Record the make, model, displayed code, recent symptoms, pressure or temperature readings shown by the controls, and whether the system serves one dwelling or a shared arrangement. Do not remove covers or work on electrical or refrigerant components; isolate the system only as described by its instructions and seek qualified help for safety-critical faults.

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.
A fault can be assessed independently, but planned insulation or internal-wall work may affect heat-loss calculations, controls and emitter requirements. Tell the engineer about completed and proposed works so the repair and any recommissioning are considered in context.
Record the display information, follow the manufacturer's safe shutdown guidance, and avoid opening the unit or handling refrigerant. Arrange assessment by an appropriately qualified professional, and use emergency services for immediate danger such as smoke, fire or exposed live electrical parts.
