Direct GOV Setting up a business

The Gov website has some great tips on starting a business.

Turn your idea into a business

1. Research your market - identify potential customers. Talk to them and find out if your idea is meeting a real need.
2. Develop and plan - test your product or service with real customers, make changes, and test it again. Keep doing this until you’re sure there’s a demand for it.
3. Find partners and suppliers - think about who you’re going to work with to develop and sell your idea.
4. Set up your business - work out which legal structure is right for you, and register for tax.
5. Get funding - explore different sources of business finance, from bank loans to government-backed schemes.
