Hot water bottles are the ultimate winter warmer. With a cold freeze gripping the UK (including snow in some areas), many of us are using them to keep cosy, but have you checked that yours is still safe?

Earlier this week, I reached for my hot water bottle to slip under my chilly duvet before bed. I'd taken all the usual safety precautions, but the moment I picked it up, water began seeping through the fluffy cover. I felt the hot water on my hand, almost burning me.

I leaned over the sink, removed the cover, and found a large gaping hole where the plastic had disintegrated.

It was a sharp reminder to check more often.

My hot water bottle was a Christmas gift from around three years ago, but I never expected to replace it so soon.

According to Gareth Lloyd Jones, sustainability expert and Managing Director at HIPPO, hot water bottles should be switched out every two to three years.

"Hot water bottles need to be replaced more often than you expect," Gareth Lloyd Jones, sustainability expert and Managing Director at HIPPO, told Ideal Home.

"After they've expired, the rubber or PVC can begin degrading, cracking or leaking and put users at significant risk of burns."

The Mid and South Essex Integrated Care System suggests checking the daisy wheel on your hot water bottle to see how old it is.

You'll find this imprinted on its neck or body: the central number indicates the year (e.g., ’22’ for 2022), while the 12 segments around this number represent months.

"To cut down on waste, there are many hot water bottle alternatives that last longer than 3 years. Microwavable heat pads contain natural ingredients such as wheat, which can be easily heated up in the microwave," adds Gareth.

    Mine was caught just in time, but a broken hot water bottle can do real damage. Check yours regularly — don't leave it as late as I did.
