What it is
A small workshop specialising in vehicle electrical work: tracing wiring faults, repairing or replacing alternators and starters, fitting accessories and diagnosing warning lights.
Your first three steps
- Look at units to rent locally and check the rent, business rates and permitted use before committing
- Work out your equipment list, including a ramp or axle stands, diagnostic tools and an oscilloscope if needed, and cost it
- Visit nearby garages and fleet owners to offer overflow electrical work and agree how you will be paid
Who pays
Car owners, local garages and dealers who sub out tricky electrical jobs, and small fleet operators.
How it makes money
Hourly labour or fixed prices per job, plus parts mark-up, with repeat work from garages and fleets.
Skills that help
- Advanced fault finding and wiring repair
- Using diagnostic equipment and reading wiring diagrams
- Managing a workshop, quotes and customer bookings
Watch out for
- Public liability insurance, and check whether you need motor trade, tools and employer's liability cover if you hire
- Planning permission or permitted use for a workshop, so check with your council
- Rules on storing and disposing of batteries and other waste, so check what applies
- Fixed costs such as rent and utilities mean quiet months can hurt
