What it is

A small online trade supplier of hot water cylinders, electric water heaters, immersion heaters and fittings. You take the orders and suppliers deliver direct to the customer or job site, so you hold little or no stock.

Your first three steps

  1. Ask manufacturers and wholesalers about trade accounts and drop-ship terms, and compare their prices and delivery times
  2. Set up a simple online shop with clear product specs, stock and delivery information
  3. Visit or phone local plumbers and heating engineers, offer them a trade account and ask what they find hard to source
Who pays

Self-employed plumbers, heating engineers, small installers and some landlords or builders who want quick, fairly priced delivery.

How it makes money

You buy at trade price and sell at a margin. Extra income can come from delivery charges and from regular accounts with local installers.

Questions people ask

How much does it cost to start an online hot water systems supplier?

Startup costs are typically estimated at around £600 to £3,000, depending on your website, supplier arrangements and marketing. Because suppliers deliver direct, you hold little or no stock, which is why the estimate is lower than for a shop.

How much can an online hot water supplier earn?

Monthly revenue is typically estimated at around £1,500 to £7,500, depending on how many installers you win and your product range. Margins can be thin against large merchants, so check your prices carefully before you list products.

What rules should I check before selling hot water products online?

Check product safety marking, water-contact approvals and energy labelling rules for items you sell. Also check whether electrical take-back (WEEE) or packaging rules apply to you, and whether your public and product liability insurance covers the goods you supply.
