Companies House software glitch
Companies House has recently confirmed that a software issue affecting its WebFiling service was identified on 13 March 2026. While the issue has now been resolved, it has raised understandable concerns around the integrity of company records.
The fault meant that, in certain limited circumstances, a user who was already logged into the system could potentially access and amend information relating to another company. This was not a widespread breach and required valid login credentials, but it does highlight the importance of checking that your company details remain accurate.
Although the risk of any unauthorised changes is considered low, Companies House has advised businesses to review their records as a precaution.
What you should check
You may wish to take a few minutes to confirm that the following details are correct:
Director information, including names, service addresses and dates of birth (where partially visible)
Persons with significant control (PSC) details
Filing history, including any recent submissions you do not recognise
Company email address registered with Companies House
Also check that no unexpected submissions have been made on your behalf.
What to do if you spot an issue
If anything appears incorrect or unfamiliar, you should contact Companies House without delay and seek professional advice. In most cases, any unauthorised changes can be corrected, but early action is important.
A reminder on good practice
This incident is a useful reminder to regularly review your company records and ensure that access to authentication codes and login details is properly controlled. Simple steps, such as limiting access and keeping records up to date, can help reduce risk.
While there is no evidence of widespread misuse, taking a few moments now to check your details will provide reassurance and ensure that your company record remains accurate and secure.
