Hi, I have replaced most of my old thermostat radiator valves with Hive smart valves that are working well. I have two radiators in my lounge that are about 20 years old but designed to look older and have a different sort of valve (see attached pictures)
. Any idea whether it is possible to replace these with Hive too and if so what I should expect to pay a plumber to do the work (Warwickshire based). Thanks
