Swimming pool owners in London are facing substantial energy costs to maintain warm water temperatures into autumn. Outdoor care specialists PBSR CO have calculated that heating a 30,000-litre pool by a single degree Celsius requires approximately 34.9 kWh of energy. At Ofgem’s average electricity rate of 26.32 pence per kWh, this equates to £9.18 for each degree the water temperature is increased.
Alex Essex, managing director of PBSR CO, highlighted the importance of budgeting for ongoing operational expenses beyond the initial installation. "The biggest mistake homeowners can make is budgeting for the pool itself without considering everything around it," Mr Essex stated. He added, "A pool should be something homeowners enjoy rather than something they constantly worry about. Understanding the full cost of ownership before installation allows people to budget properly and make a more informed decision."

Efficiency and Heat Loss
While direct electric heating incurs significant costs, many pools utilise more efficient heat pumps. A heat pump that delivers four units of heat for every unit of electricity consumed would need only 8.7 kWh to achieve a 1°C temperature rise, costing around £2.30. However, the efficiency of these systems can be affected by ambient air and water temperatures. Additional ongoing expenses for pool owners include electricity for pumps, chemicals, water supply, and routine servicing.
The primary challenge in maintaining pool temperatures, particularly as weather cools, is heat loss. Experts identify evaporation as the largest contributor to this loss. Consistent use of a pool cover can lead to considerable savings on heating costs, although the exact benefit depends on factors such as local climate and how frequently the cover is removed.

Homeowners considering an extended swimming season are advised to assess their pool's volume, the type of heater installed, their specific electricity tariff, their desired water temperature, and the frequency of cover use. Comparing electricity meter readings over similar periods with consistent cover usage can provide a more precise estimate of running expenses. PBSR CO recommends consulting local pool professionals for advice specific to individual pools and equipment, especially regarding covers and winter preparation.
The level of interest in pool upkeep among London residents is reflected in online search data. Approximately 22,880 monthly searches are made for pool maintenance and related terms, indicating that running costs and property value remain significant considerations for many homeowners.
