Office closures during public holidays

Companies House online services are available during public holidays, but the Contact Centre and Helpdesk will be closed.

Only the Cardiff office is manned to receive documents. Letterbox facilities exist in London and Edinburgh, but not in Belfast.

You can file your accounts and annual return online. You’ll need an authentication code, so if you have to request a code allow plenty of time, as they are sent to the company by post.

Accounts must be delivered to Companies House by their due date. Delays in transit will not be accepted as an excuse for late delivery.
