How to change your company address
Do note that the change will only be official once Companies House has registered your new office address, and Companies House will notify HMRC once the change has been approved.
Your new registered office address must be in the same part of the UK that your company was incorporated at. For example, if your business was incorporated in England, the new registered address must be in England. You'll need to re-incorporate your company if you move to another part of the UK.
