Estimates for a small start in the UK, not guarantees.

What it is

A web shop selling locks, padlocks, key safes, door security and replacement parts, sent by post. You stand out by explaining which lock suits which door, with clear sizing guides and fitting tips.

Your first three steps

  1. Open trade accounts with a few lock and security wholesalers and pick a focused range, such as key safes and padlocks
  2. Set up a simple online shop and write guides on measuring and choosing the right lock
  3. Order samples, photograph them well and run a small launch to friends, neighbours and local landlords
Who pays

Householders, landlords, small businesses and DIYers who know what they need but want a better range or clearer advice than a general hardware store.

How it makes money

Margin between trade and retail price on each item sold. Selling bundles, such as a lock set with fittings, can raise the value of each order.

Skills that help
  • Knowing lock types and fittings
  • Writing clear product descriptions
  • Basic online shop setup
  • Customer service by email or phone
Watch out for
  • Distance selling rules for online sales, including customer returns and refunds, so check what applies to you
  • Product liability and public liability insurance, since a faulty lock can cause real harm
  • Selling products that meet the standards customers need, such as insurance-approved locks, and describing them accurately
  • Postage costs on heavy items, which can eat into margins
  • Running a business from home may need permission from your landlord or mortgage lender, especially if you store stock there
