Energy in independent and 24-hour gyms

Owner-operated gyms and 24-hour access sites: free weights, cardio floor, resistance machines, changing rooms with showers, often a small studio and sometimes a sauna. Typically 2,000-20,000 sq ft in a retail park, industrial unit or converted first floor. There are now over 7,200 gyms in the UK and the private, independent end of the market is the fastest growing part of it.

Common energy challenges for independent and 24-hour gyms

  • Air handling units ventilating the gym floor every hour you are open, and all night if you sell 24-hour access

  • Twenty-plus cardio machines and screens drawing power from 6am until 10pm whether anyone is on them or not

  • Shower blocks reheating the hot water cylinder from first class to last

  • High-bay lighting over a big open floor that nobody ever switches down at quiet times

Where the energy goes

Typical equipment loads across gyms, fitness and leisure, with annual kWh and cost bands from published benchmarks.

EquipmentkWh a yearCost a year (est.)
Air Handling & Ventilation (gym floor, pool hall)25,000–120,000 kWh£6,250–£30,000
Space Heating (gas boilers)40,000–180,000 kWh£2,800–£12,600
Showers & Changing Rooms12,000–45,000 kWh£840–£11,250
Cardio Equipment (treadmills, bikes, rowers)8,000–35,000 kWh£2,000–£8,750
Lighting (gym floor, courts, car park)10,000–40,000 kWh£2,500–£10,000
Pool Water Heating (gas)150,000–600,000 kWh£10,500–£42,000

Energy saving tips for independent and 24-hour gyms

  1. 1

    Zone your lighting so the free weights area, cardio floor and studio can be dimmed or switched independently at quiet hours.

  2. 2

    Set your air handling units on a time clock tied to your busiest hours rather than running them flat out from open to close.

  3. 3

    Fit low-flow shower heads. Shower hot water is one of the biggest single loads in a dry gym and it is invisible on your bill.

  4. 4

    Turn off cardio consoles and screens at the wall overnight. Standby on a bank of twenty machines adds up over a year.

  5. 5

    If you sell 24-hour access, ask us to price your overnight baseload separately. Suppliers value a flat 24-hour profile very differently.

Illustrative example

What switching typically looks like for leisure

Independent gym

A 24-hour gym of around 800 square metres

Typical annual bill
£20,000£40,000
Saving at 3050%
£9,000£15,000estimated

Ventilation, showers and lighting run around the clock, so unit rates on overnight use matter.

Independent gym energy questions, answered

Published UK benchmarks put independent and 24-hour gyms at roughly 25,000 to 240,000 kWh of electricity a year and 12,000 to 400,000 kWh of gas, which comes to about £7.5k to £88.4k a year at 25p per kWh for electricity, 7p per kWh for gas and around £365 in standing charges. These are estimates from published sector data, not quotes. One recent bill turns them into a real comparison.
