Hot tubs have continued to grow in popularity across the UK—offering comfort, relaxation, and a place to unwind without stepping outside your home. But one question still comes up regularly from buyers: how much does it cost to run a hot tub?
With energy bills being top of mind for many households, it's completely fair to want a realistic picture of ongoing costs. The truth is, running costs vary depending on several factors. Let's take a closer look at what really affects hot tub running costs in 2025, and how modern spa technology is helping cut down on waste.
If you're running a hot tub in the UK in 2025, several key factors will determine your energy costs—especially with ongoing changes in electricity prices and weather patterns.
First off, the size and capacity of the hot tub play a big part. A compact 2–3 person spa uses far less energy than a larger 6-seater model. Bigger tubs mean more water to heat and circulate, leading to higher running costs—especially during colder UK months.
Next is the technology behind the hot tub. For example, the Riptide hot tubs are built with thick insulation and high-efficiency circulation systems. These energy-efficient spas reduce heat loss without drawing unnecessary power, ideal for the UK's variable climate.
How you use the spa also matters. Frequent daily use or higher water temperatures will raise energy use. But even when not in active use, a spa runs in standby mode to maintain water warmth and cleanliness with minimal electricity, though energy-efficient spas minimise this.
Don't forget the weather either. The UK's cooler climate, especially in the autumn and winter, naturally increases energy usage. If your spa is outdoors and exposed to wind or rain, it'll require more heating than one placed in a sheltered or insulated environment.
Electricity rates across the UK vary depending on your region and supplier tariff. These differences have a direct impact on your hot tub's monthly running costs.
Rather than talk in cost figures, it's clearer to look at how much electricity a hot tub actually uses. For UK buyers comparing different models, this provides a clearer picture of expected power demand, even if local energy costs differ.
Most modern spas are designed to be as energy-efficient as possible—especially during standby mode, which accounts for the majority of their operating time. A great example is the Riptide Infinity Spa, which far exceeds CEC energy efficiency standards. Here's a general guide to monthly energy consumption:
These figures are based on standby mode, where the hot tub keeps water at your set temperature and runs circulation as needed to keep it clean. It's worth noting that heating water from cold or using massage jets for longer sessions will increase usage. That said, the energy-efficient hot tub like Riptide's Infinity Spa handles such demands remarkably well with minimal waste.
Beyond electricity, there are a few other things that come with regular hot tub ownership:
These are all part of regular upkeep and tend to be simple tasks once you're into a routine.
Looking to cut your energy bills? Here's how smart choices and small upgrades can make a big difference:
Choose an energy-efficient spa: Models like the Riptide Infinity Spas, available through BETA Wellness, feature thick insulation, energy-saving pumps, and intelligent controls that keep costs manageable.
Use a quality thermal cover: A well-insulated cover traps heat effectively, especially overnight or in colder months. This reduces how often your hot tub needs to reheat the water.
Set heating schedules: Take advantage of built-in timers or smartphone controls. Heat and filter your spa only when needed—saving power when not in use.
Keep your filters clean: Dirty filters force your system to work harder. Regular cleaning ensures efficient circulation and lower energy use.
Add optional extras: Consider solar heating support, energy-efficient heat pumps, or additional insulation like wraps or thermal blankets. These affordable add-ons help retain heat—especially during winter.
Compared with other home leisure setups, energy-conscious hot tubs often offer better long-term value:
Hot tubs strike a nice balance — especially when you choose a well-insulated, efficient model. With the right home spa equipment, you can enjoy daily hydrotherapy, stress relief, and quality time, all without worrying about out-of-control energy use.
While rising energy prices remain a concern, today's hot tubs are built with efficiency at their core. With clear energy usage data, you can plan confidently—enjoying the benefits of home hydrotherapy without worrying every time the meter ticks.
Modern spas like the Infinity Spa series from Riptide are designed with UK climates and energy efficiency in mind. With average monthly usage ranging from 100–167 kWh in standby mode, depending on size, they offer a surprisingly cost-effective way to enjoy year-round relaxation at home.
Rather than guessing what your running costs might be, the smarter approach is to choose a hot tub built for efficiency. At BETA Wellness UK, luxury hot tub ownership has never been more accessible—get in touch today to find the energy-smart model that's right for you!
