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 Lincoln postcode, heat-pump type, make and model, any displayed warning code, a description of the symptoms, and available installation or service records. Photos of the controls and accessible equipment can also help with initial assessment.
An initial assessment may still be possible, but safe and accurate servicing depends on identifying the equipment and understanding the system arrangement. Gather the unit labels, controller information, commissioning documents and prior service history where available; availability is confirmed from your postcode and system details.
