What it is

A small workshop or unit with a ramp or secure bay, fitting and servicing vehicle security systems, with space for more involved jobs such as hidden wiring, upgrades and diagnostics.

Your first three steps

  1. Check the rent, rates and lease terms of small local units, and confirm the planning use class allows vehicle work
  2. Apply to become an approved or trade fitter with security product and tracker suppliers, and set up trade accounts
  3. Visit local dealers and fleet operators with a price list and offer a trial fitting at a fair price
Who pays

Private car owners, used car dealers, small fleet operators, and customers sent by insurers or tracker companies.

How it makes money

Fixed prices for fittings and upgrades, plus repair and servicing work. Regular supply to dealers and fleets can give steady volumes, and you can sell the products you fit.
