According to the UK’s energy regulator, Ofgem, the average household spends just over £1,200 a year on electricity and gas, and heating alone accounts for approximately 60% of this. Therefore, reducing your energy bills as much as possible while still keeping your home heated at a comfortable temperature is always desirable. And, by making a few tweaks to your daily lifestyle, this is perfectly possible to do. For example reducing heating and water temperatures:

Think about the room temperature that you normally set and reduce it by just 1°C – you won’t notice any difference and you can cut heating bills by up to £75 a year in a typical home, which is roughly the equivalent of a 10% reduction. Interestingly, the average temperature in a UK home is 20°C which is a full degree higher than climate change experts recommend.
You can re-set your water cylinder to a lower temperature, for example down to 60°C. (It is not advisable to set it lower than 60°C as that is the minimum temperature required to kill most pathogens in your water).
If you have thermostatic radiator valves, remember to turn them down or off in rooms that are not regular used.
