Section 1 gives the company number and name. Section 2 gives the new registered office address (building name or number, street, post town, county or region, postcode and country). The form warns that a home address used here will be available on the Companies House website and cannot be removed, that the change does not take effect until the Registrar has registered the notice, and that a person may validly serve any document on the company at its previous registered office for 14 days from the date the change is registered. An England and Wales company’s address may be in England or Wales, a Welsh company’s address must be in Wales, and a company registered in Scotland or Northern Ireland must use an address in Scotland or Northern Ireland respectively. Section 3 is a box ticked to confirm that the new address is an appropriate address under section 86(2) of the Companies Act 2006, meaning that a document delivered there by hand or post would be expected to come to the attention of a person acting on behalf of the company and that an acknowledgement of delivery can be obtained. Section 4 is the authentication by printed name (no signature is needed), given by a director, secretary, person authorised (under section 270 or 274 of the Companies Act 2006), liquidator, administrator, administrative receiver, receiver, receiver manager, Charity Commission receiver and manager, CIC manager or judicial factor (for a United Kingdom Societas, ‘director’ is deleted and the organ of the UKS of which the person authenticating is a member is inserted).
