If your Nest has stopped controlling the boiler, a failed Heat Link (the boiler-side receiver) is a common cause. This service replaces it.

The price includes the new Heat Link unit, fitting and re-pairing to your Nest display, fully tested. £150 is the total maximum – any deposit or call-out already paid credits toward it.

Price: £150 all-in.
