Companies House compliance breaks silently — until it really matters
Most UK limited companies don't miss filings because they're careless. They miss them because deadlines are buried in emails, accountants are slow, and Companies House doesn't chase you — until the penalty lands.
Late accounts penalties
Miss your annual accounts deadline and Companies House automatically issues penalties starting at £150 — doubling for repeat offences.
Missed confirmation statements
An overdue confirmation statement puts your company at risk of strike-off — a Gazette notice can appear with no warning.
Fundraising red flags
Investors and lawyers check Companies House during due diligence. Late filings and overdue accounts kill deals.

Companies House compliance — common questions
- What is a Companies House health check?
- A Companies House health check looks at your UK company's public filing data to identify overdue accounts, missed confirmation statements, late filings, and other compliance risks — giving you a score and your upcoming deadlines.
- When is my confirmation statement due?
- Your confirmation statement is due every 12 months from either your incorporation date or the date you last filed one. You have 14 days after that anniversary to file. Enter your company number above to see your exact due date.
- What are the penalties for late accounts at Companies House?
- Late filing penalties are automatic: £150 for up to 1 month late, £375 for 1–3 months, £750 for 3–6 months, and £1,500 for over 6 months. These double if your accounts were late the previous year.
- What is a DISS40 or Gazette notice?
- A DISS40 (Gazette notice) means Companies House previously flagged your company for strike-off — usually due to an overdue confirmation statement. It's a serious warning that should be addressed immediately.
- Is this tool free and read-only?
- Yes — the health check is completely free. It reads public Companies House data only. Nothing is filed, changed, or submitted on your behalf.
