Sound familiar?

You manage 120 companies.
You're tracking deadlines in a spreadsheet.

Every year-end, every confirmation statement, every director change — checked manually. And now ECCTA means tracking identity verification for hundreds of directors on top of everything else.

"I started with a spreadsheet but always worried I had a formula wrong."

Conditional formatting, separate tabs per filing type. One wrong formula and Thornton & Webb's confirmation statement slips past you.

"Companies House Follow floods my inbox."

50+ companies on Follow means dozens of unfiltered emails per week. No dashboard, no priorities — just noise mixed in with everything else.

"A director was appointed and nobody told me."

The directors of Meadowbrook Dental Practice changed their registered office without telling you. You found out six weeks later from a bounced letter.

"How do I track ECCTA verification for 400 directors?"

Every director across your portfolio needs identity verification. The transition window is ticking. Cartwright Engineering alone has four directors — none verified.

Companies House issued 317,985 late filing penalties last year — a 10% increase. Penalties start at £150 and double for consecutive years.

Action required: Companies House identity verification

Dear James,

Under the Economic Crime and Corporate Transparency Act, all directors must verify their identity with Companies House. Our records show this hasn't been completed for your role at Pemberton Catering Ltd.

This must be done before your next confirmation statement on 15 November 2026.

How to verify: Visit account.companieshouse.gov.uk and follow the identity verification steps. It takes about 10 minutes.

Kind regards,
Sarah Johnson
Smith & Co Accountants
