People are just realising there's a secret switch on doors to make them less draughty

As the temperatures drop and bills rise, many of us are thinking of cheaper ways to keep our homes warm.

And one TikTok user has shared an incredibly simple, free hack for those who have UPVC doors - check it out here:

If you’ve noticed that your doors are feeling a little bit draughty as we head into winter, then this simple change could have a big impact.

TikToker Alijacy shared a step-by-step guide showing how to alter UPVC doors so they pull in the seal tighter and fit more snugly in the frame - meaning there’s less chance of a draught getting in. Clever, eh?

He explained: “Just a little tip if you have UPVC doors and there a bit draughty, they have a summer and a winter setting.”

He then opened his door to reveal the small metal sliders, on which you’re able to twist them and make the seals tighter.

He went on: “So on the sliders they have a little mark, you twist it out and then it will pull your seals tighter.”

The tighter seals mean warm air won't get out and cold air won’t get in.

Many TikTok users were completely unaware of the simple trick with one person writing: “Why don't they tell you this when they fit the door?”

Another wrote: “Wow, I never even realised.”

And a third said: “Wait… 43 YEARS and now you’re telling me this information?”

While someone else confirmed: “It actually does work, just done mine and I had a gap in top of door and now I don’t. Thank you.”

Another person suggested that you may need an allen key to do the job properly, posting: “Not quite, most doors it would be an allen key adjustment for compression, if it’s that loose it’ll roll back the first time it engages on the keep.”

Earlier this year, a mum shared an equally simple, yet money-saving, hack.

Writing on Mumsnet, the woman explained she had saved £95 with the trick, which was sent to her by Octopus Energy.

The woman wrote: "You can use less gas by checking your flow settings on your boiler. Mine was set to 80 degrees by default which meant I was spending huge amounts on heating up water that then has to be cooled down with cold water.

"I'm taking part in the Octopus Winter Workout and according to them I have saved £95 since the beginning of December and this is the only substantial change I have made.

"I assumed everyone knew about this except me but my sister hadn't heard of it and she's very hot on money saving so I thought there must be others out there."
