I'm pretty sure, but not 100%, if you're planning on replacing that thermostat with a hive one you'd also need to get power to it (so I think they're normally wired in at the boiler).
I replaced a thermostat like that with a netatmo smart one as you only needed the two wires and no power.

@konastab01 well spotted, I rather avoid touching the boiler 🥶 @aggi great! Are you happy with it? Did you get radiator valves too? If you did do you need a temperature sensor on the radiator or does the valve include one?

Want to replace the existing thermostat (simple wall one, not programmable or smart) with something a bit current (Hive?!) that will allow us to set programmes and hopefully save some energy.Will the new unit just need one cable in the permanent live and one on the permanent neutral?! Is it really that simple? We just have a combi boiler and set up seems too straight forward to be true https://www.screwfix.com/p/hive-mini-wireless-heating-smart-thermostat/150pv#product_additional_details_container
