What it is

You sell and install alarms, CCTV cameras and smart entry products at customers' homes and small businesses, then show them how to use the system. You can buy kit from trade wholesalers and fit it yourself.

Your first three steps

  1. Take a recognised alarm or CCTV installation course and check what electrical training you need
  2. Open trade accounts with a couple of security wholesalers and build a starter kit and van stock list
  3. Offer discounted installs to friends, neighbours and local landlords and ask for reviews
Who pays

Homeowners, landlords, small shops, offices and tradespeople who want to protect their property.

How it makes money

A mark-up on equipment plus a fee for installation. Some installers also add a small monthly charge for servicing or remote monitoring support.
