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.

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.

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.

Hotties Microhottie Microwave Hot Water Bottle
Quick and easy to heat (in one to three minutes)
No need to empty or refill
Safe for kids
Comes with machine-washable cover
Only stays warm for three to four hours
Some say it’s a little small

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.

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.

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.
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.
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.
