Stop chasing Companies House deadlines.
PenaltyProof tracks confirmation statements and annual accounts for every client on your list — and emails you 30 days out, 7 days out, and on the day. Built for UK accountants and bookkeepers.
The alerts you actually need. None of the overhead you don't.
Most deadline tools are practice management systems first, alerts second.
Practice management software tracks Companies House deadlines — but it also costs £15–50/month, requires onboarding, and asks you to work inside a new dashboard every day. PenaltyProof is just the email alerts. No new workflow. No new software to learn. Add your clients once and get on with your work.
Companies House emails you about confirmation statements on the due date. Not before.
The free Companies House reminder arrives when the filing window opens — which is already the deadline day. If you're a busy practice, that's not a warning, it's a panic. PenaltyProof sends three: 30 days out (plan it), 7 days out (action it), on the day (last call). The first two are the ones that matter.
If you're tracking deadlines in a spreadsheet, you're one busy month away from a missed filing.
Many smaller practices manage Companies House deadlines in Excel with manual checks. It works — until it doesn't. PenaltyProof covers your full client list from £0. Free for up to 5 companies, £19/month for up to 20. No spreadsheet to maintain. No manual checks.
No contracts. Cancel anytime. Annual billing available — contact us.
Company limits apply to Companies House-registered entities only. Clients not registered at Companies House don't count toward your limit.
FAQ
Common questions
Confirmation statements and annual accounts for UK Companies House-registered entities — limited companies and LLPs. We don't currently track HMRC deadlines, VAT returns, or payroll obligations. Those are on the roadmap.
Currently, alerts go to one email address per account. If you need alerts forwarded to a colleague, a Gmail or Outlook rule works well as a short-term workaround. Multi-user support is on the roadmap.
No. PenaltyProof only reads publicly available data from the official Companies House API — the same information anyone can view on the Companies House website. No accounting software access, no HMRC data, no client financials.
Companies House sends one reminder per company — and for confirmation statements, it arrives on the due date, not before. You'd also need to register each company separately. PenaltyProof covers your entire client list from one signup, and alerts you 30 days out and 7 days out, when you can still act.
We send from a dedicated sending domain and follow email deliverability best practices. We recommend adding alerts@penaltyproof.co.uk to your contacts when you sign up. You also receive a monthly digest summarising all upcoming deadlines — a second safety net if an individual alert is missed.
