.co.uk is a familiar choice for UK businesses. .uk is shorter and puts your name directly before the country ending. Neither ending automatically includes the other.
Choose for your audience
Think about the name customers will remember and type. Say both versions aloud, check the spelling and consider whether your business already uses one on printed material or email.
Check both independently
An available .uk name does not prove the .co.uk version is available, and the reverse is also true. If you register both, you can choose one main website address and arrange a redirect using your hosting provider.
Registration is not a trade mark check
Check existing brands and trade marks before registering. Owning a domain does not give permission to use a name that infringes another person’s rights.
