If you're struggling to sleep during the UK heatwave and have been fantasising about sitting in an air conditioned home, we're here to make that dream a reality

Some of us have already kitted out our homes with cooling devices, including the top-rated Dyson fan and mini desk fans to keep cool in our home office. Others have sought out paddling pools to relax in. And this cooling pillow insert is doing a roaring trade on Amazon.

Purchasing an air conditioning unit likely isn't something you've considered. They seem costly, cumbersome and probably a little pointless considering how many sweltering days we experience a year.

But with global temperatures rising it's looking to be a good investment. According to a 2021 Met Office study, if global warming continues at its current rate, the number of extremely hot days in the UK could increase four-fold from around 10 days a year now to 37 days a year.

With that in mind, we've hunted down six top-rated miniature air conditioners on Amazon for under £50 - which are not only effective but also don't take up much space.

And, bonus, many have been slashed further in Amazon's early Prime Day sale, so you can save some extra cash. Want to browse more heatwave essentials?Check out our round-up of discounted desk fans, paddling pools, pet cooling mats and more.
