Best hot water bottles for warmth and comfort this winter

When it’s chilly outside, there’s nothing better than snuggling up on the sofa with a hot water bottle or sinking into a pre-warmed bed at the end of a busy day. We've rounded up the best hot water bottles to keep you warm, as recommended by Mumsnet users.

By Lucy Cotterill | Last updated Dec 20, 2023

Selection of the best hot water bottle

A trusty hot water bottle is a valuable addition to any home and is a quick and easy way to provide extra warmth when temperatures drop. With energy bills remaining high, using the best hot water bottle can offer a cheap way to get warm without relying too heavily on central heating.

Along with other penny-saving solutions for keeping toasty like finding the best electric blanket for your mattress and warming your feet with a pair of the cosiest women's slippers, selecting a good quality hot water bottle is a cost-effective way to stay warm in the depths of winter. Heat therapy can also be effective at relieving aches, joint pains, and period cramps according to the NHS, so it's a good idea to have a hot water bottle on hand even on milder days.

To help you pick the best hot water bottle for your needs and budget, we thoroughly researched tried-and-tested recommendations from Mumsnet users, the biggest online network of UK parents. We also carefully analysed expert opinions and combed through authentic consumer reviews to make sure every option we suggest is effective, safe and offers good value for money. All the products featured are suitable for adults, but if you're looking to kit out the whole family, we have a round-up of parent-approved kids' hot water bottles too.

"I looooooooove my hot water bottle far too much. It’s just an ordinary one from Boots, but it has a lovely furry cover. I’d rescue it in a fire before my husband, I reckon."
See Post
Our verdict

If there’s one hot water bottle that Mumsnet users can rely on for providing hours of heat on cold winter days, it’s this faux-fur option from Boots. An affordable and traditional hot water bottle, it might not look particularly fancy, but it earns the top spot on our list thanks to its fluffy, cosy cover that feels just like a warm hug on a cold day.

Made from latex-free PVC, it’s easy to fill, leakproof (when filled correctly) and retains the heat well, with a cover that stays soft even after multiple washes. We'd snuggle up with one of these under the best blanket hoodie on particularly chilly nights.

“The only one to have is a YUYU long hot water bottle. They are amazing, you can curl them around you or wrap them around an achy back. I have had mine for years and have given so many as presents and everyone has loved them so far.”
See Post
Our verdict

According to Mumsnet users, this long hot water bottle is nothing short of amazing, and we have to wholeheartedly agree. The award-winning YUYU is a cosy delight - a long, slim bottle with a plush fleece cover, it simply moulds around the body for maximum comfort.  

Thanks to the integrated strap, it’s ideal for those experiencing chronic pain. Simply pop it around your waist or lay it across your back to soothe aches hands-free while you curl up on the sofa or go about your day. It also has insulated lining, so this great companion can stay warm for up to six hours. Keeping it in tip-top shape won’t be an issue either as its cover is machine washable at 30°C.

"I swear by the Hotties. I use them several times a day and we've had our current Hotties for about four years. They stay really warm for a long time too."
See Post
Our verdict

With a huge variety of designs to choose from, Hotties give a quick source of warmth with no faff and no hot water to worry about. The internal thermal pack takes just 60 seconds to heat up in the microwave, and they offer consistent warmth and speedy relief for general aches and pains.

While the level of heat retention over lengthy periods won’t compare to a traditional hot water bottle, we’d still be happy to swap the best winter coat for women for a Hottie after getting in from a day out in the cold. Its smaller size also makes it ideal for tucking under a blanket on the days you’re working from home.

“My White Company one stays warm all day.”
See Post
Our verdict

Whilst this fluffy faux-fur option from The White Company is one of the pricier hot water bottles on our list, it’s really not hard to see why. A stylish design in neutral shades, this high-quality natural rubber water bottle includes a zip-on cover made from a super-soft long pile, making it a luxurious addition to your sofa or bedroom setting in lieu of a heated throw.

Made from recycled plastic bottles, this sustainable choice also makes an excellent gift for those who feel the cold or love to be cosy. While the lighter shades may show up marks more easily, the cover can quickly be removed and machine washed for a quick refresh as and when required.

Best large hot water bottle

What we like
  • Good value for money

  • Comes with a super comfy fleece cover that feels like velvet

  • The stopper is easy to tighten and open

Our verdict

Whether you’re lying in bed, working at a desk or relaxing on the sofa, it’s easy to escape the chill under an extra-large hot water bottle like this one. The durable Vagabond Hot Water Bottle is ribbed on both sides without that unwelcome rubbery scent, plus it has a safety handle for stress-free filling, although some found this a bit flimsy. It offers heat across a larger area than other hot water bottles on our list, and the fleecy cover is a real treat too.

The cover has a wide opening, so you can remove the bottle with ease, and it comes with an elastic band that scrunches at the top to keep it tidy. Reviewers also like that the stopper feels sturdy and leakproof.

I have the WUKA one and I like it. Although I often take it off before it has cooled down because I have warmed up enough!”
See Post
Our verdict

Many of us seek out some pain relief when that time of the month arrives and this long, wearable hot water bottle from WUKA is brilliant for the job. It comes with two ties to provide a snug fit around your tummy or back, helping ease those inconvenient period aches and pains, especially in the lower back area. You could even wear it around your neck and shoulders to ease upper body tension when working from home.

We love the soft fleece cover with a pocket to keep your hands warm - we'd pair it with the best women's dressing gown for ultimate comfort on chilly days. The cover is suitable for machine washing at 30ºC too, but make sure you leave the fabric conditioner out.

“This one is amazing for cuddling in bed.”
See Post
Our verdict

Another attractive full-length design, this long teddy hot water bottle is super soft, so it's perfect for cuddling when you crawl into bed at the end of a busy day.

Thanks to the cosy cover, it offers excellent heat retention at a really affordable price. It’s also long enough to warm your entire body, allowing you to stay toasty and comfortable all evening, and you can pop the cover in the washing machine for easy care. Our only complaint is that there's just one colour option available, but other than that, it's hard to find fault.

Are hot water bottles safe?

When used correctly and with care, yes. Like a heated gilet, they even have health benefits as they can be used for easing aches and pains. However, there are some basic safety steps you should follow when using a hot water bottle to keep you safe:

  • Don’t use boiling water - If using a traditional style hot water bottle, you should allow your boiled kettle water to cool for a few minutes before adding it to the bottle.

  • Don’t overfill - Only fill your bottle to two-thirds of its full capacity to avoid the risk of bursting.

  • Take care when filling - The best way to fill your bottle is by holding it upright by the neck, and add the water slowly and carefully to avoid burns.

  • Tightly seal - Ensure that the seal is screwed tight to prevent spillage and wipe down the outside before adding to the bed.

  • Look for the kitemark - A hot water bottle should always comply with British Standards, so look for those bearing the Kitemark symbol for peace of mind.

  • Replace them regularly - For rubber-based hot water bottles, it’s recommended you replace them every two years, as rubber naturally deteriorates with time. 

  • Use a cover - Using a hot water bottle with a cover is preferable, as this can prevent the risk of burns from direct contact.

  • Supervise - You should never leave a child unattended with a hot water bottle. 

  • Handle with care - Do not lie or place significant weight on top of the bottle. 

  • Check before each use - Look for any signs of wear and tear and replace if there are any visible leaks or signs of damage. 

How we chose the best hot water bottle

Recommendations from real parents

Because we know that there’s nothing like an honest, independent recommendation, we first headed to the Mumsnet forums to find out which hot water bottles our discerning Mumsnet users had tried, tested and loved, and which ones had got them through cold winter nights.

Consumer feedback

We then broadened our search and did some research across the wider web, looking at which hot water bottles had been featured in ‘best buy’ lists across websites, and what customer reviews said about them. We analysed what users had to say about special features such as ease of use, heat retention, pain relief, price point and, of course, comfort.

Expert guidance

Finally, we check to see which products have won industry awards and received recognition from trusted sources and feed this into our analysis too.

Having collated all that information, we then narrowed our list down to the best hot water bottle options on the market.
