As the temperature drops, many of us are reaching for our cosy jumpers and winter duvets as we try to delay switching on the heating. While energy prices aren’t as high as they have been, the cost of living crisis still persists, and we all want to keep our household bills down.

So, when is the best time to turn on your heating? And what else can you do to keep your home warm? Here’s what you need to know as winter approaches.

When is the best time to turn on your heating?
The best time to turn on your heating in the UK is a subject of debate. However, most experts agree that it is when the temperature consistently drops, the nights get longer, and the clocks go back. This year, that will be on Sunday 29 October.

Should you keep your heating on all day?
The Energy Saving Trust advises against leaving the boiler on for longer periods as it will cost more. It’s better to have it on only when you need it. The Met Office suggests setting timers to turn the heating on before you wake up and off after you go to bed. If no one is at home during the day, you can have it turn off before you leave and on again just before you return.

What temperature should your boiler be?
Both the Met Office and the Energy Saving Trust note that it will cost more in energy bills to turn the heating up than to leave it on for longer periods. Set your thermostat between 18°C and 21°C, or up to 23°C if there are elderly or vulnerable individuals at home. Bedrooms can be slightly cooler, with the NHS recommending a temperature of 16°C to 20°C for babies’ bedrooms.

This temperature recommendation differs from the boiler temperature, which refers to the temperature of the water inside the pipes. According to the Energy Saving Trust, a regular boiler shouldn’t have a temperature below 65°C to prevent bacterial growth, while a combi boiler should have a temperature no lower than 60°C.

Does turning down radiators save money?
Most radiators have controls on the side to adjust the temperature. When used correctly, these thermostatic radiator valves can save you money. The numbers on the valves do not indicate specific temperatures, but the Energy Saving Trust suggests starting with settings of three or four and adjusting as needed if the room is too hot or too cold.

Does bleeding your radiators save money?
Bleeding your radiators can save money by removing air bubbles that impede the heating process. Experts recommend bleeding your radiators annually as it starts to get cold, making now the perfect time to do it.

To bleed a radiator, use a screwdriver or radiator key to turn the valve at the top until you hear a hissing noise. Keep an old cloth nearby to catch any water that may come out. The bleeding process is complete when the hissing stops and you can close the valve.

Heat the rooms you frequently use and forget about the rest
If you’re concerned about expenses, focus on heating the rooms you use the most by adjusting the radiator controls. Don’t forget to close the door to rooms you’re leaving unheated and consider using draught excluders to keep your rooms extra snug.

Stay warm without turning up the heating
Wearing warm clothing and using cozy bedding can help keep you warm even if your home is chilly. Opening your curtains when the sun is shining can also provide some warmth. However, remember to close them when the sun sets to keep out the cold.

Get government assistance with heating costs
The government offers additional help with heating costs for pensioners and individuals on certain benefits. If you already receive benefits or a state pension, you can check if you qualify for further assistance. Additionally, local councils often have support funds for households facing financial challenges.
