People are discovering there's a hidden switch on doors to make them less draughty

Unfortunately, Britons know how unpredictable the weather can be in summer.

While we have been blessed with some beautiful days in April and May, it’s not guaranteed we’ll experience weeks of stunning sunshine this season.

While we hate to wear jumpers and use hot water bottles in summer, they’re fantastic ways to keep warm without flipping on the heating.

Another way you can keep yourself warm is by draught-proofing your home.

If you’ve noticed wind whistling through your doors or a slight breeze flowing through your home, then one TikTok user’s hack could have a serious impact.

Those with UPVC doors - check out the below:

Last year, social media star Aljacy took to TikTok and shared a step-by-step guide showing viewers how to alter UPVC doors.

His video saw him pulling in the seal tighter so that it fit more snugly in the frame - meaning there was less chance of a draught getting in.

Explaining his free and simple door hack, Alijacy said: “Just a little tip if you have UPVC doors and they're a bit draughty, they have a summer and a winter setting.”

He then panned in on small metal sliders featured on some UPVC doors.

“The sliders they have a little mark, you twist it out and then it will pull your seals tighter.”

Tightening the door seals meant there would be no space for cold air to blow in and that warm air wouldn’t be able to escape either.

Many TikTok users were shocked after witnessing the trick, with one person writing: “Why don't they tell you this when they fit the door?”

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

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

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

A fifth suggested that you may need to find an Allen key to do the job properly.

They typed: “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.”

If you’re wanting to stop draughty doors to save money on your heating bill, then a mum has another hack that may benefit you.

Taking to Mumsnet last year, the woman explained she’d saved £95 with the trick, which was sent to her by Octopus Energy.

She 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.”
