@cjr FWIW, I'm increasingly thinking that if I can pick up the required bits fairly affordably I might use my friendly/good value plumber/heating engineer to do a zone for each floor, then add in TRVs later if needed. It will cost more than Tado but I'm very sensitive to noise so don't think I could cope with a TRV in our bedroom.
Will have to pray for a sale on Nest thermostats. Friendly plumber's mate who did our gas certificate recently was saying he reckons Hive is better but so ugly...
