💡 What Affects Hot Tub Running Costs? The hot tub cost doesn’t stop at the initial purchase. Ongoing hot tub operating costs depend on several key factors: Electricity Usage Heating water is the biggest expense. On average, a well-insulated hot tub costs between £1 and £2 per day to run, depending on usage, insulation quality, and energy tariffs. Insulation & Build Quality Premium tubs with full-foam insulation and high-quality covers retain heat far better, significantly reducing hot tub running costs over time. Water Temperature & Usage Keeping your tub at 38–40°C continuously costs more than heating it occasionally. Frequent use is actually more efficient than letting the water cool completely. Pump & Filtration Time Circulation pumps and filtration cycles use electricity. Efficient systems help keep hot tub operating costs lower while maintaining clean water. Chemicals & Maintenance Water treatment chemicals, filters, and occasional servicing typically add £10–£20 per month to the cost of running a hot tub.
