Change of Principal place of business

Hi, almost one month ago I changed in Tax Service Principal place of business. Unfortunelty it still has status "Pending". What could be the reason for such a long waiting time for approval? What I should do to change it? How long it should take to change this adress? Thank You.

Hi,

If your business address is for a limited company, you can register the change of address using form.

Change a company's registered office address (AD01) 

If you are changing the address of a sole trader or business parthership, then you could webchat with the Self Assessment team at:

Self Assessment: general enquiries

Thank you.
