Hot tubs can be a delightful addition to any home, offering relaxation and a chance to socialise in your own garden. But one of the most common questions from potential owners is simple: are hot tubs expensive to run in the UK? Understanding the costs involved, from energy usage to maintenance, helps you make an informed decision before buying.
In this article, we’ll break down average monthly energy costs, look at the factors that affect running expenses, and share practical cost-saving tips. By the end, you’ll have a clearer picture of what to expect when it comes to hot tub running costs in the UK.
Understanding Hot Tub Running Costs
The main expenses involved in running a hot tub are heating, filtration, and powering the jets. On average, a hot tub can consume between 150 and 300 kWh per month, depending on usage frequency and the model itself.
According to the Energy Saving Trust, typical hot tub running costs per use in the UK can range from £2 to £8, with insulation, exposure to the elements, and temperature settings making the biggest difference.
Heating Costs
Heating is by far the largest contributor to your energy bill. To give an idea:
- Small model: Around 200 kWh per month, costing roughly £30–£50 based on standard energy rates.
- Large model: About 300 kWh per month, translating to £50–£80.
In practice, a modern, well-insulated hot tub uses between 3 and 7 kWh per day. That works out to about £1.50–£3.50 daily or £45–£105 per month on current tariffs, with most households falling near the middle at around £75 per month.
Factors Influencing Running Costs
Several variables affect your overall spend:
- Insulation quality – good insulation keeps the water hotter for longer, reducing heater demand.
- Frequency of use – using your hot tub daily will naturally cost more than using it once or twice a week.
- Time of year – heating demands rise during autumn and winter, with energy bills increasing by as much as 30% compared to summer months.
Real-world reports suggest most owners see their energy bill rise by about £1–£1.70 per day, or roughly £30–£50 a month, after adding a hot tub.
Cost-Saving Tips for Hot Tub Owners
Running costs don’t have to spiral if you take a few proactive steps:
- Use a thermal cover – prevents unnecessary heat loss.
- Lower the water temperature slightly – even a couple of degrees can save a noticeable amount of energy.
- Time your usage – running during off-peak hours can reduce costs if your energy plan allows it.
By adopting these practices, many owners save between £10 and £15 per month without compromising comfort.
Conclusion
Running a hot tub in the UK isn’t free, but it doesn’t have to be prohibitively expensive either. Heating and insulation are the biggest factors, and your usage habits play a major role in the final bill. By applying small cost-saving strategies, you can keep expenses manageable while still enjoying the luxury of your spa.
