Hey good lookin’ Google Nest Learning Thermostat, £187, John Lewis & Partners

The Nest smart thermostat from Google is not only super-stylish, it’s also packed with features. It can track your smartphone and use your location to turn the heating and hot water on or off. Nest recommends professional installation and the thermostat doesn’t offer zonal control, so you can’t adjust the heating in individual rooms. We love: Nest’s learning feature, which gets to know your heating routines and adjusts energy use automatically to make sure you only use what you need, helping to save you £££s.
