What it is
You add an approved MOT testing bay to a garage or workshop you already run or rent. Testing brings drivers in on a regular cycle, and you can offer repairs and servicing to the same customers.
Your first three steps
- Check on GOV.UK whether your existing premises and layout could meet DVSA requirements
- Get quotes for the missing test equipment and compare them with your likely test volume
- Arrange a qualified tester (train yourself or hire) and start the DVSA application
Who pays
Local drivers, existing garage customers, small businesses and fleet owners.
How it makes money
A test fee per vehicle, with the maximum set by government, plus repair and servicing work that follows from tests.
Skills that help

- Tester training and annual updates are required, so plan time and cost for them
- Check your insurance covers testing work
