Repair is separate from routine servicing and concerns a reported fault or loss of performance. A diagnostic visit may investigate fault codes, failure to heat or make hot water, unusual noise, icing, leaks, low pressure, poor circulation, control or sensor issues, defrost behaviour, or an outdoor unit with restricted airflow. The technician should establish whether the issue is within the heat-pump circuit, controls, emitters, hot-water components, electrical supply or building fabric before recommending corrective work. For properties affected by heritage controls, constrained courtyards, shared access, apartment blocks or ongoing retrofit works, any repair or component replacement should account for safe access, reinstatement and compatibility with the existing installation. No fault pattern, engineer coverage, response time or price is implied by this page.

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.
Note the exact code and affected functions, such as space heating or hot water, and provide a photograph before arranging a diagnostic repair visit. Do not remove covers or work on refrigerant or electrical components yourself.
Yes, the system can be assessed as part of the wider installation, but the visit should include the heat pump’s controls, emitters, insulation, hot-water components and any linked solar or communal equipment. Havering identifies heat pumps and fabric measures within its council-home retrofit programme.
