What does a UK company secretary actually do?
Whether you’re a chartered company secretary, a board administrator, a paralegal or an accountant looking after Cosec for clients, the role boils down to one thing: keeping the company legally and operationally compliant. In the UK, that means maintaining statutory registers, filing changes with Companies House, managing PSCs (people with significant control), running board and committee meetings, recording minutes and resolutions, and acting as the bridge between directors and shareholders.
Under the Companies Act 2006, every UK public limited company must appoint a company secretary, and most private companies — especially those with venture, PE or institutional shareholders — choose to either employ one or outsource the function. The work is high-stakes (miss a confirmation statement deadline and Companies House can strike the company off the register) but also high-volume, with most of it being repeatable, deadline-driven admin. That’s exactly the kind of work AI-powered software handles best.
How CoSec App automates every core company secretarial task
CoSec App is built around the day-to-day workflow of a UK Cosec team. Each module below replaces a manual process with an automated, auditable one — backed by AI assists for the parts that have, until now, eaten hours of every week.
Statutory registers, maintained in real time
Maintain the register of members, register of directors, register of PSCs, register of charges and every other statutory register from a single source of truth. Any change to officers or shareholders updates the relevant register automatically and writes an audit-trail entry — no parallel spreadsheets, no version drift.
Companies House filings, generated and submitted in-app
File confirmation statements (CS01), appointments and resignations (AP01, TM01), PSC notifications (PSC01-09), share allotments (SH01) and change-of-name forms (NM01) without leaving the app. CoSec App pre-populates every form from your central entity data and submits straight to Companies House via the official software-filing gateway.
Board and committee meetings, end to end
Schedule meetings, build agendas, distribute board packs securely, capture minutes (with AI-assisted minute-taking that drafts a clean version from your notes), and track resolutions — all in one place. Directors get a single login for every committee they sit on.
Compliance calendar and deadline alerts
Every UK statutory deadline — confirmation statements, accounts, PSC reviews, AGM notices — sits on a shared compliance calendar. Configurable alerts ping you by email, in-app and dashboard so deadlines never sneak up on you again.
Built for UK compliance — Companies Act 2006, ECCT Act 2023, Companies House 2027
Generic global governance tools weren’t built for the specifics of UK statute. CoSec App is. The platform is updated continuously to reflect Companies House guidance and UK legislation as it changes, so your team doesn’t have to chase the updates.
Companies Act 2006 alignment
Every form, register and workflow in CoSec App is mapped to the requirements of the Companies Act 2006. Director and PSC records are captured in the format Companies House expects, including the new identity verification fields introduced under the Economic Crime and Corporate Transparency Act 2023 (ECCT Act).
Ready for the ECCT Act 2023 reforms
The ECCT Act 2023 introduced mandatory identity verification for directors and PSCs, a registered email requirement for every UK company, and changes to how registered offices are validated. CoSec App captures and stores these fields by default and surfaces verification status on the entity dashboard.
Ready for Companies House software-only filing (2027)
Companies House is moving to software-only filing for accounts and other returns by April 2027. CoSec App is already integrated with the Companies House software-filing gateway — when the mandate lands, your Cosec team is already on the compliant rails.
