Nest thermostat 3rd gen, heat link replacement

[Lambz]

Have had my Nest for just over 2 years ( I think ) and it suddenly stopped working.  I've had my boiler engineer out who also installed it and was told that the heat link is faulty.  The Nest has no power going into it and the app on my phone is showing as offline.  How do i get a replacement?

Hi @Lambz. I'm sorry to hear that you're experiencing this issue, but no worries, help's here! Let's start with a few questions:

What type of Nest thermostat do you have?
Did the issue happen during installation or after installation? Was it installed by a Nest Pro or by a regular installer?
Are there any lights on the Heat Link? Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode?
Are you seeing any wiring report or error on the thermostat and/or the app?
Have you had any recent power cuts in your area? If yes, has the power been restored?
Have you recently had service or maintenance on your electrical, plumbing, or heating system?
Have you tried any troubleshooting steps before contacting us?
How many thermostats do you have?
