Martin Lewis issues verdict on whether to leave the heating on all day

Here are some other tips for keeping costs down as well

As the evenings grow longer and the chill sets in, many across Britain are contemplating when to reignite their heating systems for the approaching winter months. The perennial question arises - is it more cost-effective to keep the heating on continuously or to activate it only when necessary?

Money Saving Expert Martin Lewis provided clarity on the matter during an appearance on ITV's This Morning, saying: "They say it's better to only put the heating on when you need it."

He explained that paying to pump energy as required is more economical than maintaining a constant flow. "You pay to pump energy in as and when is needed, and to keep pumping it in constantly isn't efficient. Using a timer's best, because your thermostat is designed to turn your heating on and off to keep your home at the temperature you set it at. So in general I'd stick with that."

Martin also touched upon the issue of condensation, saying: "There are some engineers who argue that keeping the heating on low with all the radiators on and the boiler down can work as it reduces condensation, which when the heating is turned off collects within the walls, and can help conduct heat outside the home. This means you lose heat more quickly and will use more energy as a result. So if your house is prone to that you may want to think about it," reports the Mirror.

Other ideas to slash your heating bills include:.

• Wrapping tin foil behind radiators

Astonishingly, simply placing this everyday kitchen staple behind your radiators can significantly boost a rooms warmth. The tin foil works by reflecting the heat back into the room, preventing it from being lost through the walls.

• Rearranging your furniture

Strategically moving bulky items like sofas or armchairs away from radiators ensures that you're not hindering the heat distribution, allowing for a cosier home during the chillier months.

• Drawing your curtains

Sealing off the heat's escape route through the window panes with drawn curtains or blinds can keep your living space snug.

• Dialling down the thermostat

Turning down the thermostat just a notch could see you pocketing extra cash every week. Opting for a moderate 18C instead of a lavish 20C or 25C is often advised for both your wallet and the environment.

• Leaving the oven door open after use

Leverage the lingering warmth from a recently used oven to fend off the evening's nip in the air a simple yet effective move.

• Investing in a rug for the floor

Besides its aesthetic appeal, a plush rug can also serve as an insulator, trapping heat and rendering your floorboards less icy.

Covering your wooden or laminate floors with an insulating cotton rug may seem like a simple solution, but it can make a significant difference to how cold you feel when walking around the house.

• Keep a jumper on

Don't be too quick to remove your jumper when you get home from work. By keeping an extra layer on, you'll reduce the need for heating and save money in the process.

• Draft-proof

Draft-proofing your home can also lead to substantial savings on your heating bills. Use gaffer tape to seal any cracks in floors and walls, and block the bottom of doors with old clothes, towels or a specifically purchased draft-excluder.

• Forage for wood

If you have access to public woods, consider foraging for firewood. This free fuel can help your fire burn longer, reducing the need for heating and lowering your bills. However, remember that some woodlands leave dead wood in place for wildlife.

• Get a hot water bottle

Consider going back to basics with a traditional hot water bottle. Using one in bed could significantly reduce your overnight heating bills.

• Doors

If you have a south-facing room that gets plenty of direct sunlight, keep the door open to allow the warm air to circulate around the house. And finally, once the sun has set, close the doors to your living room or bedroom to trap the cosy air inside.
