Describe the symptom, any message and whether the concern is constant or intermittent.
Availability confirmed from postcode and system details
Begin with a safe symptom-led diagnosis: record what the system is doing, when it occurs, display messages, unusual noise, pressure or flow indications, and whether heating or hot water is affected. Prioritise checks of power supply, controls, sensors, filters, water pressure or flow, defrost and condensate arrangements, and communication between system components, without bypassing safety controls. Use the manufacturer's service information and retain a clear record of findings, parts replaced, settings changed and recommendations for follow-up. Escalate suspected refrigerant, electrical, combustion-backup or sealed-system work to appropriately qualified personnel, and do not promise a repair outcome before inspection.

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 the postcode, system make and model, installation or commissioning documents, service history, warranty details, symptoms and any displayed fault codes. Safe access to relevant controls and equipment will help the assessment.
Not reliably. A fault code is a useful starting point, but diagnosis should consider the complete system, including controls, sensors, flow, emitters, hot-water components and the outdoor unit. A repair recommendation should follow inspection rather than assume a particular failed part.
