How much does it cost to run a pool per month in the UK

When you think about getting a pool, don’t just consider the upfront costs. The true cost of pool ownership extends far beyond installation.

To run a pool every month, you have to spend on heater, pump, chemicals, maintenance and more. The cost also depends on the size of the pool and how much you use it. However, in a standard pool, you have to spend £150-£500 per month.

Monthly Energy Costs to Operate the Pump and Heater

To run a pool, the largest monthly expense comes from the pump and heater. Depending on the size of your pool and how often you use it, the cost can be from £50 to £200 per month.


Your pool pump circulates and filters the water to keep it clean. It typically runs for 8-12 hours a day in the summer. It can cost you from £50-£100 per month. The more powerful your pump and the longer it runs, the higher your energy bill. An energy-efficient, variable-speed pump can help to lower the cost.


Heating your pool requires a significant amount of energy. Gas or Solar heaters tend to be more affordable to operate than electric heaters. Running your heater for just a few hours a day can add £50-£150 to your monthly bill. Using a pool cover when the heater is off will help retain heat and lower usage.

Other factors

The location of your pool and climate also play a role. Pools in warmer areas typically cost less to heat and operate. In-ground pools are usually more energy efficient than above-ground pools.

Pool Chemicals and Water Balancing Expenses in the UK

For a safe and clean pool, you will need to spend money on chemicals and test kits. The costs of these chemicals and kits depend on the size of your pool and how often you use it. We need the following chemicals and kits to run a pool.

pH Levels

You can use soda ash or baking soda to increase the pH level. To decrease, you can use muriatic acid or sulfuric acid. Each product costs around £10 to £30 per month.

Additional chemicals

Offseason vs Peak Season Cost Differences in the UK

The costs of running a pool depend on the season. During the peak season of summer, expenses are typically higher. But, in the offseason, costs are often lower since the pool is less frequently used.


To keep your pool at a comfortable temperature during the colder months, you’ll need to run the pool heater. This can cost between £200 to £400 per month depending on the size of your pool and how frequently you use it. The heater is the single biggest cost that differs between seasons.


You will use more pool chemicals during summer because the sun can break down chlorine chemicals. Expect to pay 25-50% more for chemicals from June through August versus the rest of the year. Always follow the directions and don’t overdose the chemicals.


Running the pool filter, lights, pumps, and other equipment requires electricity. Your bill will be higher in the summer when the pool is used daily and equipment runs for longer periods. You can expect to pay 50% more for electricity. However, this cost can be low if you use gas heaters and pumps.


With frequent pool use comes more maintenance. You’ll need to check chemical levels and clean the filter more often. The pool may need vacuuming, skimming, and scrubbing down more frequently too. This additional work can cost £50 to £200 more per month during peak season.

Tips to Reduce Your Monthly Pool Spending

To reduce how much you spend on your pool each month, here are some tips:

Adjust the Timer

The pump and filter are two of the biggest energy drains for a pool. Adjust the timer so the pump only runs for 6-8 hours a day instead of the usual 10-12 hours. This can save 20-30% on your electric bill each month.

Use a Pool Cover

A pool cover can help retain heat, reduce evaporation, and keep out debris. Using a pool cover when the pool is not in use can lower heating costs by up to 70% each month. The cover also prevents leaves and dirt from getting in the pool, which cuts back on filter usage.

Turn Off Lights and Heaters

Turn off all pool lights, heaters, and jets when the pool is not in use. These features draw a lot of energy even when idle. Use them only when necessary to heat the pool or for nighttime swimming.

Reduce Chemical Usage

Only add pool chemicals as directed to properly balance the water. Adding too many chemicals will not only damage the pool equipment but also your wallet. Test the water regularly to ensure the proper chemical levels.

Consider Using a Pool Vacuum

Rather than using a filter to clean the pool, you can use an automatic pool vacuum to do some of the work. Vacuums can cut filter run time in half and save on the energy bill.


So there you have it. The true costs of running a pool each month in the UK. Pools are the best for entertainment and exercise. But before owning a pool, go with realistic expectations about the financial responsibilities. Plan your pool budget wisely, otherwise, you may end up with an expensive monument.
