You can immediately start using your spouse’s last name after marriage. All you need is to send copies of your marriage certificate to any organization that has a record on you. Your records should be updated free of charge.This applies to both men and women, including those in same-sex marriages.
 If you’re a couple combining names, or if you want to use your maiden name as your middle name, you’ll need to change your name using a deed poll.This is a document you can draw up that states you are abandoning your previous name and using your new name at all times.


You can pay someone £15-35 to draft the document for you.
You can also make your own deed poll by using the sample deed poll available here: https://www.gov.uk/change-name-deed-poll/make-an-adult-deed-poll.
Have two people witness you sign the document.
