Upcoming Companies House Changes: What You Need to Know for 2027

Significant changes are coming to the way companies file their accounts with Companies House—and now is the time to start preparing.

From 1 April 2027, all company accounts must be filed using commercial software, marking the end of paper and online (web-based) submissions.

These updates are part of Companies House’s wider plan to modernise the register, improve data accuracy, and enhance security. Below, we’ve outlined the key changes and what they mean for your business.

Software-Only Filing from April 2027

  • Paper and web-based filing routes will be permanently closed.
  • All accounts must be submitted through approved commercial software, regardless of whether they are filed by directors or through an accountant or third-party agent.

This change applies to all companies, so if you currently rely on Companies House’s online filing system or submit paper forms, you’ll need to make the switch.

Changes for Small and Micro Companies

From 1 April 2027:

Small and micro-entity companies will also face new reporting requirements.

Micro-entities must file both a balance sheet and a profit & loss account.

Small companies will need to file:

  • A balance sheet
  • A directors’ report
  • A profit & loss account
  • An auditor’s report, unless exempt

Note: Abridged accounts will no longer be accepted for filing.

New Audit Exemption Requirements

If you’re claiming an audit exemption, directors will need to:

  • State the exemption being claimed
  • Confirm the company qualifies for that exemption on the balance sheet

Restrictions on Changing Accounting Reference Dates

Companies will be limited to shortening their accounting reference period once every five years, unless they can demonstrate a valid business reason for doing so.
