Electricity use in leisure centres and pools

Long opening hours and pools that run around the clock make leisure centres heavy electricity users. Start by understanding what makes up the overnight use.

Expect a high base load from pool pumps, ventilation and dehumidification, with opening hours from early morning to late evening, seven days a week.

What to check first

  • Pool hall ventilation and dehumidification running at daytime levels overnight
  • Filtration pumps that could run more slowly outside opening hours
  • Sports hall and studio lighting left on between bookings
  • Saunas, steam rooms and water heaters switched on earlier than needed
  • Equipment that kept running while the centre was closed for maintenance

Setting the opening hours

Opening hours vary by day and change during school holidays, so enter them carefully. A centre open 14 hours a day has a short closed period, and small changes to settings in that period make a big difference.

Use these as a starting point. Each site is compared with its own calendar, so getting the hours right matters more than the type of building.

How does your building compare?

To see whether a site's total use is high for its type, compare its kWh per square metre with the government survey ranges in our electricity benchmarks by sector. Then use the half-hourly pattern to find out why. Questions about the analyser itself are answered in the FAQ.

Thinking about solar panels? The analyser's Capacity tab shows how much of a system's output a building like this would use itself, and the UK Solar Calculator works out the cost and payback. See sizing solar from half-hourly data.

Questions people ask

Is a high base load normal for a pool?

Yes. Pool equipment has to run continuously. What matters is whether it runs harder than needed outside opening hours, for example ventilation at full speed overnight.

What should I look at first?

Overnight use, and how quickly demand falls after closing. Pool covers and slower overnight ventilation and filtration are common places to start.
