I'm looking at replacing my boiler thermostat. Current thermostat just has one pair of wires going to it like this:

I'm assuming this is just a switch and, as such, all the smart thermostats that seem to require mains power wouldn't be compatible without extra wiring, I'd need something battery powered? Am I understanding that right? Cheers

If you're going with smart TRVs, you probably don't even need a thermostat.

As it is, and afaik, most smart thermostats are battery powered in any case.

Probably only going for TRVs on half of the radiators so will still need something to control the rest.

Yes, thermostat isn't quite right. A lot of the smart thermostats are wireless and battery powered but have some form of link/hub which wires into that spot where the thermostat was.
