If this is going to be an additional UK establishment, you don't have to deliver the constitutional documents. You may instead state in the registration document that you have delivered them in respect of another UK establishment - but you must give the registered number of that establishment.

If there is a change in the parent state that affects your company, you must deliver the notifying form to Companies House within 21 days of the date on which notice of the change could have been received by post in the UK.
