Only the Cardiff office is manned 24/7 to receive documents delivered by hand or post. The London and Edinburgh offices have a letterbox for out of hours deliveries, but the Belfast office doesn’t.

Posting accounts

Accounts must be delivered to Companies House by their due date. If accounts are filed late, the company will issued with a late filing penalty.

The Registrar of Companies cannot accept delays in transit as a reason to waive a penalty.

Anyone filing documents at Companies House should:

  • understand their legal responsibilities
  • be aware that postal and other delivery services may be subject to loss or delay. Royal Mail’s published figures (September - November 2014) on delivery performance show that as much as 7.1% of first class mail may not be delivered by the next working day after posting
  • note any industrial disputes or other factors which may make it difficult for a carrier to deliver on time
  • select a reliable delivery service, using a guaranteed delivery service when posting close to a deadline
  • ask us to acknowledge receipt of documents by providing a stamped addressed envelope and a copy of your covering letter. Please note, this only confirms that we have received the document, not that it has been examined or registered
  • check their own company record regularly to ensure details held at Companies House are up to date
  • send documents for English and Welsh companies to the Registrar in Cardiff
  • send documents for Scottish companies to the Registrar in Edinburgh
  • send documents for Northern Ireland companies to the Registrar in Belfast

Guidance on the legal responsibilities of company directors, the due dates for filing accounts and the delivery of documents to the Registrar of Companies can be found in our guidance.
