What it is

A small shop or unit with doors on display, plus handles, hinges, locks and frames. Customers can see and touch the products, and you order in what is not on show.

Your first three steps

  1. Talk to local builders and joiners about what they buy, where they buy it and what frustrates them
  2. Open trade accounts with a few door manufacturers and wholesalers and ask about display deals and minimum orders
  3. Shortlist affordable units on a trade estate or secondary high street and work out your rent, rates and stock costs
Who pays

Homeowners doing renovations, local builders, carpenters, joiners and landlords.

How it makes money

You buy from manufacturers or wholesalers and sell at a margin. Extra income comes from fittings, finishes, made-to-measure orders and trade accounts for regular builders.

  • Check the planning use class and lease terms for any premises, plus business rates and any small business relief
  • Doors are bulky and easily damaged, so plan storage and delivery, and check your insurance covers stock and public liability

Questions people ask

How much does it cost to open a door showroom in the UK?

Startup costs are typically estimated at around £15,000 to £60,000, depending on premises, display range and stock. Large stock orders tie up cash, so starting with a small display range can help keep the initial outlay down.

How much can a door showroom earn?

Monthly revenue is typically estimated at around £8,000 to £40,000, depending on location, range and how many trade customers you win. That is revenue rather than profit, so allow for stock, rent, rates and other running costs.

What rules should I check before opening a door showroom?

Check the Building Regulations for fire doors, including certification, correct fitting and what you can say to customers. Also check the rules on cancelling made-to-measure orders, the planning use class, lease terms, business rates and your insurance cover.
