Do the swearing ceremony deliver by royal mail or dhl

I think there may be some confusion here!

In the UK, the swearing-in ceremony for new citizens is typically conducted by the Home Office or a local authority, not by Royal Mail or DHL. The ceremony is usually held at a designated location, such as a town hall or a civic centre, and is attended by the new citizen, their family and friends, and representatives from the Home Office or local authority.

Royal Mail and DHL are private courier companies that specialize in delivering mail and packages, not conducting citizenship ceremonies!

If you have any further questions or concerns about the swearing-in ceremony or the citizenship process, I'd be happy to help.
