Smart thermostat reviews you can trust

All the major smart thermostat brands are covered in our reviews, from Hive to Nest to Netatmo - but our Best Buy smart thermostats aren't necessarily from names you'll be familiar with.

Which? is independent – we work for you, the consumer, so you can be sure that our product recommendations are influenced only by our test results. We're not influenced by third parties and we don't accept freebies from product manufacturers or retailers. We buy all the products that we test ourselves, so our advice helps you to make the right choice first time and avoid costly mistakes.
