Moving to a different address in the UK does not normally end your Child Benefit if you still meet the usual conditions, including being responsible for the child. You should tell HMRC about your new address and update any payment details so letters and payments are not delayed. If you move abroad, or your child moves to another household, the rules can be different and your entitlement may change. Check the latest guidance on GOV.UK and report changes through the official Child Benefit service.
