What it is

A small wholesale operation from a rented unit with chilled and frozen storage. You buy in bulk, store, portion or prepare orders, and supply local trade customers by delivery or collection.

Your first three steps

  1. Speak to your local council's food safety team early about the unit you have in mind and what registration or approval you would need
  2. Get quotes for a suitable unit, chilled and freezer rooms, and a chilled delivery vehicle
  3. Line up two or three suppliers and some trade customers willing to commit to regular orders before you sign any lease
Who pays

Restaurants, fishmongers, delis, caterers, care homes, schools and event food businesses that buy regularly.

How it makes money

You buy in larger volumes at better prices and sell in smaller trade quantities. Extra income can come from simple preparation such as portioning, if your premises are approved for it.

Skills that help
  • Understanding fish quality, handling and storage
  • Stock control and buying
  • Food safety management
  • Selling to trade customers and managing accounts
Watch out for
  • Premises may need approval rather than registration if you handle or prepare fish for other businesses, so check with your council before spending on fit-out
  • Fit-out, refrigeration and electricity costs can be high, so get several quotes
  • Food safety plan, temperature records and traceability for every batch
  • Public liability, product liability, stock and equipment insurance, plus employer's liability once you hire
  • Fresh stock spoils quickly, so overbuying is a real risk
  • Trade credit terms: late payers can cause cash flow problems
