How to choose a smart thermostat for a UK home

Boiler type, wiring, OpenTherm and subscriptions — the four checks that decide which smart thermostat suits your home.

How COMANORA works

Our method, and how we make money

1 · Research

We read the manufacturer's UK product page and installation documents, and list the main sources with the date we checked them.

2 · Check fit

We check each product against UK homes: boilers, heat pumps and OpenTherm for heating; power, chimes and Wi-Fi for doorbells and cameras; and renting.

3 · Rank

We rank on published criteria — compatibility, three-year cost, features and warranty — before any shop link is added.

4 · Label

Pages say "Researched" unless we have genuinely installed and used the product. Manufacturer claims are always marked as claims.

Affiliate links, explained. In future, some shop links may earn COMANORA a small commission at no extra cost to you. Today none are active. Commission never affects which products we recommend or their order — commission data is kept apart from our rankings.
