Companies House Filing System Jams: What This Means for Your Monday Morning

Companies House Filing System Jams: What This Means for Your Monday Morning

Companies House confirmed on 11 June that it was experiencing delays in processing account filings and cannot process same-day filings until further notice. If you were counting on electronic filing being instant (as it has been for the past decade), this particular Monday may have come as something of a shock.

The Technical Reality

The filing system is receiving documents and queueing them properly, but they're not appearing on the API or webservices that most practitioners rely on for confirmation. Think of it as posting a letter that gets received by the postroom but never makes it to the intended desk. Companies House has reassured customers they can continue filing as normal, though "normal" now means filing blind and hoping for eventual visibility.

This matters because we're entering peak filing season for companies with March year-ends. The nine-month deadline means June marks the beginning of serious filing anxiety for anyone who hasn't already submitted their accounts.

What Changed This Week

The technical issue appears to be system-wide rather than affecting specific types of filings. Same-day processing (that reliable feature that allowed last-minute filers to submit accounts on deadline day with confidence) is suspended indefinitely. Companies House has not provided a timeline for resolution, which in bureaucratic terms usually means "we don't know either."

The timing is unfortunate given the ongoing changes to filing requirements. From November, all third-party filings will require Authorised Corporate Service Provider (ACSP) registration: a change that was already causing administrative headaches without adding technical delays to the mix.

Your Monday Morning Workflow

If you filed accounts last week and they haven't appeared on the register, don't panic immediately. The documents are received and queued, according to Companies House. But don't rely on this as an excuse for deadline-day filing either.

For accounts due this month, file at least a week early if possible. The usual advice of "allow time for technical rejections" has evolved into "allow time for the entire system to catch up with itself." Any accounts submitted in June should be filed with the assumption that confirmation may take several days rather than minutes.

Check client deadlines immediately. Anyone with accounts due in the next fortnight should be advised of the delays and encouraged to file early. The penalty for late filing remains automatic and unforgiving. Companies House's technical difficulties won't constitute grounds for appeal.

The Bigger Picture

This technical hiccup comes at an awkward moment for Companies House, which has been positioning itself as a modernised, digitally-capable regulator following the Economic Crime and Corporate Transparency Act reforms. The same organisation introducing identity verification requirements and digital-only filing can't currently confirm that its basic filing system is working properly.

For practitioners, this serves as a useful reminder that electronic filing, while generally reliable, isn't infallible. The old paper-filing advice of "allow extra time for postal delays" has morphed into "allow extra time for system delays": progress of a sort.

The ICAEW has confirmed it's monitoring the situation and will update members as information becomes available. Professional speak for "we're watching this mess unfold along with everyone else."

Next Steps

File early, file often, and maintain paper trails of submission confirmations even if they're delayed. For clients with tight deadlines, consider advising them of the technical issues and documenting that advice in your files.

The next major filing deadline approaches on 30 June for companies with September year-ends, assuming Companies House has sorted its technical difficulties by then. Based on their track record with system implementations, that optimism may be premature.
