What it is

A small high street or trade unit selling alarms, cameras, locks and related kit to walk-in customers, with an installation and servicing service run from the same base.

Your first three steps

  1. Work out your numbers: rent, rates, stock and fitting time against likely local demand
  2. Open trade accounts with a few security wholesalers and choose a core product range
  3. Find a small unit and check the lease terms and permitted use before signing
Who pays

Homeowners, landlords, tradespeople and small businesses, buying products and paying for fitting and servicing.

How it makes money

Margin on products sold over the counter, installation fees, and recurring servicing and repair work. Having a shop helps build trust and local repeat business.
