How much energy does a gym use per year?

A standard gym without pool facilities typically uses 90,000 to 200,000 kWh of electricity annually, with gas usage of 25,000 to 60,000 kWh mainly for shower hot water, though this varies with size and opening hours.

Why do gyms have two daily demand peaks?

Gym attendance typically spikes early morning before work and again in the early evening after work, creating two concentrated periods of high equipment, lighting and shower demand each day rather than a single midday peak.

Does a swimming pool significantly increase gym energy costs?

Yes. Pool heating runs continuously to maintain water temperature and can substantially increase both gas and electricity consumption compared with a standard gym without wet facilities.

Should a multi-site gym operator combine energy contracts?

Many operators benefit from a consolidated multi-site contract, which can align renewal dates, simplify billing and sometimes improve negotiating position, though individual site consumption still needs assessing separately.

Are gym energy standing charges high?

Standing charges are generally moderate to high compared with a small retail unit, reflecting the electrical capacity needed for multiple cardio machines, air conditioning and lighting running throughout long opening hours.

When should a gym renew its energy contract?

Around 3 to 5 months before the current deal ends, giving time to compare suppliers properly, particularly where multiple sites need coordinating onto aligned contract terms.

Typical gym energy consumption

Consumption depends on floor area, equipment count and whether the site includes wet facilities such as a pool, sauna or steam room, which add materially to both fuels.

Gym type	Electricity (kWh/yr)	Gas (kWh/yr)
Small studio (under 500 sqm)	50,000 - 90,000	10,000 - 25,000
Standard gym (500-1,500 sqm)	90,000 - 200,000	25,000 - 60,000
Gym with pool/spa facilities	200,000 - 400,000+	60,000 - 150,000+

Indicative annual consumption by gym type Ranges are indicative and vary with equipment count, opening hours and building fabric.

What drives the cost

Cardio machines, particularly treadmills, drawing continuous power during use
Air conditioning and ventilation to manage heat and air quality in workout areas
Shower hot water systems, often the largest gas load
Lighting across studios, changing rooms and reception, often left on all opening hours
Pool and sauna heating where present, running continuously

Gas versus electricity split

Most standard gyms are electricity-led, with gas limited to hot water and space heating. Facilities with a pool or sauna see gas consumption rise sharply, sometimes matching or exceeding electricity use depending on how heating is fuelled.

Peak period exposure

Gyms see demand peaks in early morning and early evening as member numbers spike around work patterns, increasing simultaneous equipment use, lighting and shower demand. This creates a double peak pattern each day rather than a single midday peak seen in some other sectors.

Standing charges and contract structure

Standing charges reflect the connection capacity needed to run multiple pieces of equipment and climate control simultaneously. Multi-site gym operators often benefit from consolidated multi-site contracts that align renewal dates and simplify billing across locations.

Contract length and renewal timing

Fixed contracts of 1 to 3 years are typical, with longer terms sometimes favoured by larger operators seeking budget stability. Renewal comparisons should begin 3 to 5 months before expiry, particularly for multi-site operators coordinating several contract end dates.

How to compare gym energy prices

Confirm whether pool, sauna or steam facilities are separately metered
Provide consumption data covering a full year including seasonal heating variation
For multi-site operators, request consolidated quotes across all locations
Compare standing charges as well as unit rates given long daily opening hours
