Question: how much does it cost to change the name on your passport uk?
Answer: If your passport is still valid, you'll need to apply for a new 10-year passport nonetheless, in order to update it with your new name. Unlike your driving licence, you cannot simply update the one you've got, and you'll need to pay the normal renewal fee (£ 75. 50 for adults, £ 49 for children under 16.)
