What it is

A website or marketplace shop selling electrical supplies such as cable, sockets, switches, lighting and consumer units. You can keep a small amount of stock at home or a unit, or arrange for suppliers to send orders for you. A tight niche, like LED lighting or smart home fittings, is easier to run than a huge range.

Your first three steps

  1. Pick a niche, such as lighting or cable, and compare prices from wholesalers and online rivals
  2. Open trade accounts with a few wholesalers or distributors and ask about dropship and small order terms
  3. List 30 to 50 products on your own site or a marketplace and test it with local electricians
Who pays

Self-employed electricians, small builders, landlords and DIY customers who want a good price and fast delivery.

How it makes money

You buy at trade prices and sell at a margin. Profit comes from repeat trade customers, bundles and a good delivery offer.
