My next question is, is this possible for me to do, or do you need to be
Corgi registered?


It is a very simple job, not dramatically more complicated than wiring a
plug. There is no need for CORGI registration. However, exactly what will be
required will depend on the thermostat chosen and your boiler. Do you have
model numbers?

I don't know any more than the fact that it's a Sime Friendly, I believe
there are a few "sub-models". I don't have a manual (any more),
something I want to chase up...

Thanks,
