• Provide the full property postcode and describe the symptom, when it began and whether heating, hot water or both are affected.
• Have the make, model, commissioning information, service history and any displayed fault code available if possible.
• Keep access clear to the indoor controls, cylinder or buffer tank, and outdoor or ground-loop equipment.
• Record recent changes such as a power cut, control-setting change, building work, insulation work or unusual weather exposure.
• For properties in one of Sunderland's conservation areas or with other heritage constraints, check the council's planning and conservation guidance before external alterations; designation can mean that works normally not requiring planning permission need consent.
• The council advises that insulation can reduce heat loss, so consider the building fabric and emitter performance alongside heat-pump servicing rather than treating every comfort problem as a heat-pump fault.
