How much does it cost to leave your central heating on all night?

THE cold snap has sent temperatures plummeting, which has led many to wonder whether they should keep their heating on all night. Energy bills rose again this week, which means leaving your radiators on overnight could result in a very expensive bill. The overall cost of running central heating depends on various factors, including the type of boiler you have and, of course, the size of your home.

According to recent data from the Energy Saving Trust, the average cost of gas is 6.29 p/kWh for a typical three-bedroom semi-detached house. This means that if you have a 24kW boiler, it would cost you £1.50 an hour to run. This is less expensive than under last year's energy price cap, but it could still push your bills up across the entire winter period.
For example, if your heating is on overnight for eight hours at this charge, it could cost you £12. Multiply that by seven, and you’re paying a staggering £84 for the week. Over several months, that's a lot of money. Of course, prices will vary depending on factors such as the temperature of your thermostat.
It's also important to consider what tariff you're on, as this could determine how much it costs you to have central heating on through the night. For example, Economy 7 or 10 tariffs mean you'll pay less at night but a higher rate during the day. It's better to have your heating on for a few hours in the evening and then set the timer so it comes on an hour before you plan to get up.
