What it is
A trade-only supplier of car alarms, immobilisers and related security units, sold to garages and installers through a simple website, phone and email. You can start by passing orders to a wholesaler or manufacturer who ships direct, then hold a small stock of fast-selling items.
Your first three steps
- Contact several UK wholesalers and manufacturers about trade accounts and drop-shipping terms
- Make a short list of local garages and installers and ask what brands and products they struggle to get
- Set up a simple trade order form or website and offer first-order discounts to a few installers
Who pays
Independent garages, auto electricians, car audio and accessory fitters and mobile installers who fit units for vehicle owners.
How it makes money
You buy at trade or wholesale prices and sell at a margin, with extra from fitting kits, remotes, sirens and sensors. Repeat orders from regular installers are what build the business.
Skills that help
- Understanding of car security products
- Sales and relationship building
- Organised with orders and stock records
Watch out for
- Check which products insurers accept, as some policies expect approved security categories (for example Thatcham)
- Check product compliance rules for electronics and radio devices, such as UKCA or CE marking
- Check whether you need to register under WEEE and battery rules as a seller of electrical products
- Trade customers often ask for credit terms, so decide how you will manage late payment
- Public liability and product liability insurance are worth checking before you sell
