Availability confirmed from postcode and system details
Repair is for an identified problem such as a heat pump that will not start, repeated alarms, poor heating or hot-water output, abnormal noise, icing, leaks, circulation issues, sensor or control faults, or a suspected refrigerant or electrical fault. A repair assessment should distinguish the heat pump from connected components such as controls, pumps, valves, cylinders, emitters and the electrical supply, then document fault codes and safe test findings. Do not reset protective devices repeatedly or open sealed refrigerant circuits; provide the model, serial information, alarm display, recent changes and photographs of accessible components where safe. Heritage constraints and restricted city-centre access may affect how a repair is investigated or how replacement components and external works are planned, but the actual remedy must be based on the system details rather than the postcode alone.

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.
Record the exact code, controller message, affected functions and timing, then check only the user-level guidance supplied for your model. Avoid repeatedly resetting electrical protection or opening covers. A repair assessment should test the heat pump and connected controls, hydraulics, emitters, cylinder and electrical supply rather than assuming the outdoor unit is the cause.
Yes. Changes to insulation, room use, emitters, controls or hot-water demand can alter heat loss and operating requirements. Cheshire West and Chester Council promotes energy efficiency and retrofit, including renewable heating options, so keep retrofit records and ask for system settings to be reviewed after relevant building work.
