Check out A-rated boilers
You can find a range of brilliant boilers with our partner CORGI HomeHeat. All of these boilers are A-rated – meaning they score top marks for efficiency. In fact, switching from an old G-rated boiler to a new A-rated condensing boiler (with a programmer, room thermostat, and thermostatic radiator controls) could save you up to £630 a year on your energy bills.2
The boilers come with a smart thermostat. This handy tech lets you adjust your home heating through an app, so you can keep on top of when your home is heated, and the temperature.

2 According to the Energy Saving Trust (July 2023), a detached household moving from a G-rated boiler to a new A-rated condensing boiler with a programmer, room thermostat and thermostatic radiator controls (TRVs) could save up to £630 a year. Savings will vary depending on the size and thermal performance of your home. Here are their calculations.
3 OVO’s 2019 analysis of academic research into the effectiveness of feedback on energy consumption behaviours indicates that being able to monitor your energy usage by installing a smart meter and having access to energy insights information can lead to a reduction in energy use. The reduction in energy use results from the customer making changes to their habits by curtailing home energy use through actions such as optimising heating settings or switching lights off. The actual savings achieved will vary depending on individual energy use and the nature of changes made to a customer’s energy habits. OVO’s energy tracking is currently available for the majority of OVO customers and will be made available to all remaining customers soon.
