If you’re in the market for a new hot tub, one thing you might be worried about is how much it costs to run. It’s vital that you get the right information on this and do your own research. There would be nothing worse than not being able to use your lovely new hot tub because it’s too expensive to run!

The amount your hot tub will cost to run will vary depending on a number of different factors, so there’s no simple answer to this question. The best way to figure out the costs of running a hot tub is to do a bit of your own research and consider your own specific needs and circumstances, like how much you might use your hot tub, or your geographical area.

To help, we’ve written this guide on how much hot tubs cost to run. We might not be able to give you the exact figure, but we can help you come up with a good estimate for your circumstances – so there are no nasty surprises.

How much electricity does a hot tub use?

There are a number of different factors that will contribute to how expensive your hot tub is to run. We’ll go through them all in this article. First, let’s start with the energy a hot tub will use.

The main running cost for a hot tub is electricity, used to keep the water in the spa warm. Most owners of modern hot tubs expect to add around £20-£40 to their monthly electricity bill to keep their hot tub running. You may not realise this – but hot tubs actually operate all the time. This is because it’s more efficient to heat the water to a set temperature and keep it there so it’s ready for use, rather than letting the water cool down and reheat it.

The amount of electricity your hot tub uses will obviously vary depending on the type of hot tub you buy and your usage patterns. But some other factors will also affect the cost of the energy for your hot tub. Here’s the full list.

The type of hot tub you buy

Most modern hot tubs are a lot more efficient than older models. There have been massive improvements in the efficiency of the heating elements used, and things like LED lights have made the energy use of lighting on the hot tubs negligible. Plus, better insulation on hot tub shells and cabinets has significantly helped their efficiency.

However, if you’re worried about the running costs, stay away from older models or particularly cheap brands. These are often cheaper upfront because manufacturers are skimping on insulation or the heating element, meaning you’ll end up paying a lot more in energy costs each month.

The quality of the cover

The type and quality of cover you choose for your hot tub can have a big impact on your electricity bill. A high quality hard cover with lots of insulation that’s been designed to fit your hot tub properly will stop heat from leaking out the top of your hot tub, saving energy and ultimately saving you money.

Price of energy, economy meters etc.

Obviously, the price of the electricity you use will affect your running costs. If you’ve got a hot tub, it’s more important that you make sure you’re on the cheapest tariff you can find. It’s also worth looking at things like economy-7 meters, which can save you money on the costs of keeping your hot tub warm overnight.

Climate

This might be another obvious one, but it’s worth bearing in mind. If you live in a colder climate, it’ll take more energy to keep your hot tub warm all the time. If you live somewhere really cold, like Northern Scotland, it may even be worth draining your hot tub over the winter, as the costs to keep it running could be prohibitive.

Size of the hot tub

You shouldn’t just choose the biggest hot tub you can find! Pick one that’s appropriate to the number of people you’ll usually have. While it may be nice to have enough space for all your friends at one time – you may end up regretting that choice when you get your electricity bill.

Servicing and maintenance costs

Servicing and maintenance costs are part and parcel of owning a hot tub. Things can and will break or go wrong, and you’ll have to shell out to fix them. The costs of this will depend on how much hot tub maintenance and servicing you want to do yourself, how old your hot tub is, and how often you use it.

Our advice? Get a professional service at least once a year. You might save money by skipping this, but it’s a false economy – you’ll end up paying more for costly repairs for parts that go wrong. Preventative maintenance is the best way here.

Water care

The last expense that you’ll have to deal with when it comes to figuring out how much a hot tub costs to run is the water care products. You do need to regularly treat your hot tub water to ensure it remains clean and pH neutral. Check out our article on how to clean your hot tub here.

The exact amount this will cost will depend on how often you have your hot tub serviced, as well as the size of your tub. But in general, expect to pay around £200 a year for these products. It’s not a lot, but it can make the difference.

To conclude, then – the amount your hot tub will cost to run will vary. But, by following the advice in this article, doing your research, and then making sensible choices, you can keep the cost manageable. Hot tubs are very affordable, and most modern options won’t make a massive difference to your electricity bill. Plus, there’s a ton of benefits to owning a hot tub too – we think it’s money well spent.
