Availability confirmed from postcode and system details
Structured diagnosis of heating or hot-water loss, unusual noise, leaks, poor circulation, control faults, sensor alarms and freezing or condensate-related symptoms. Checks that distinguish a heat-pump fault from issues in controls, power supply, hydraulics, emitters, insulation or hot-water components. For conservation-area or heritage properties, repair planning that minimises unnecessary fabric disturbance and flags when planning, conservation or listed-building advice may be needed. Clear explanation of findings, parts or follow-on work required, and safe interim steps where appropriate; no fault or repair outcome is assumed 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 your postcode, system make and model if available, whether heating or hot water is affected, any displayed alarm code, and installation or service records. Photos of controls or visible symptoms can help with triage, but they do not replace an on-site diagnosis.
It can. North Herts Council's official guidance presents retrofit as a coordinated set of measures that may include insulation, heating controls and heat pumps, and points residents to Hertfordshire retrofit advice. A service assessment should therefore consider the whole heating system rather than treating every symptom as a compressor fault.
