What a typical service or repair garage uses and pays across the UK, from published benchmarks.
Figures are estimates from published UK benchmarks priced at 25p/kWh electricity, 7p/kWh gas and about £365 a year in standing charges. They are not quotes. See how we estimate.
Owner operated service and repair workshops, from two ramp local garages to ten bay independents doing servicing, diagnostics, clutches and cambelts.
A compressor that pulls current all day whether anyone is on the trigger or not
Shutter doors opening every time a car comes in, taking the heat with them
High bay lighting over every ramp, on from eight in the morning until the last job is out
Diagnostic rigs, laptops and a growing EV charging load nobody budgeted for
Typical equipment loads across motor trade and vehicle repair, with annual kWh and cost bands from published benchmarks.
| Equipment | kWh a year | Cost a year (est.) |
|---|---|---|
| Air Compressor (screw or piston) | 7,200–26,400 kWh | £1,800–£6,600 |
| Workshop & Forecourt Lighting | 8,000–25,000 kWh | £2,000–£6,300 |
| Workshop Space Heating (gas warm air / radiant) | 25,000–200,000 kWh | £1,750–£14,000 |
| Spray Booth & Bake Cycles | 27,000–96,000 kWh | £1,900–£13,200 |
| Vehicle Lifts, Ramps & MOT Bay Equipment | 2,500–9,000 kWh | £625–£2,250 |
| Jet Wash, Vacuums & Hot Water | 4,000–18,000 kWh | £1,000–£4,500 |
Walk the air line with soapy water. Leaks typically waste 20 to 30% of everything the compressor produces, and a single 3 mm hole runs to roughly £700 to £1,000 a year on its own.
Drop the compressor pressure setting to the minimum your air tools need. Every extra bar costs you roughly 7% more electricity.
Zone the lighting so you can light two ramps rather than eight, and fit LED high bays with sensors in the tyre bay and stores. Lighting is the highest electricity demand in a typical garage.
Fit an air curtain or a faster shutter on the main door. In a gas heated workshop the door is where most of your heat goes.
If you have added an EV charge point, check your capacity and your tariff shape. Charging at the wrong time of day can quietly rewrite your bill.
Illustrative example
Four ramps, a compressor and a gas-heated workshop
Compressors, lifts and space heating for an open-fronted workshop drive a winter-heavy bill.
