Swim spas hold a much larger volume of water than a hot tub, so they require more energy to heat and circulate. According to running cost guides, the average swim spa owner spends around £210 per month on energy, chemicals and water. Of this, about £180 per month goes on electricity, based on a typical consumption of around 600 kWh; chemicals account for under £30 per month and water usage about £3 per month.
Energy use depends on factors such as the climate, how often you use the jets, the set water temperature, the quality of insulation and the type of cover. A well‑insulated swim spa with a thermal cover will hold heat longer and cut your power bill. Installing an air‑source heat pump can reduce daily costs to as little as £3 in summer and £7 in winter, and may pay for itself within three years.
Keeping the water balanced with sanitiser, pH adjuster and shock treatments costs under £30 per month. If your swim spa has a self‑cleaning system, you may be able to go up to a year between water changes, which keeps water bills low. Otherwise, plan to drain and refill every three to six months to keep the water fresh.
Location also affects running costs. Outdoor swim spas in colder regions will lose more heat than those installed indoors or in a sheltered area. Frequent use, higher water temperatures and leaving the cover off will also raise your energy consumption. Upgrading to energy‑efficient pumps and modern control systems can cut electricity use.
Swim spas cost more to run than hot tubs because of their size and powerful pumps, but they still provide year‑round exercise and relaxation at a fraction of the cost of maintaining a full‑size swimming pool.
