Economic Crime & Corporate Transparency Act Roadmap 
The Economic Crime & Corporate Transparency Act (ECCTA) Implementation Roadmap provides a clear, chronological guide to the rollout of the ECCTA. It helps company directors, shareholders, company secretaries and administrators understand both when key reforms were implemented and are due to take effect and what they need to make sure they are doing or preparing to do.
A substantial group of changes came into force in both March 2024 and November 2025, with further reforms expected up until 2028. It has recently been announced that (1) the package of accounts reforms have been delayed and will now come into effect in April 2028; and (2) the introduction of identity verification for those filing on behalf of companies has been delayed from no earlier than November 2026 to no earlier than November 2027. Companies House has said it will give at least six months' notice before these requirements are brought into effect.
By bringing together the main legislative milestones and commencement dates in one place, the roadmap supports compliance planning and wider preparation for private limited companies particularly in their engagement with Companies House. The ECCTA is a wide ranging piece of legislation and as such this roadmap is purely concerned with administrative changes as they affect SME private companies.
Purpose of the Economic Crime & Corporate Transparency Act Implementation Roadmap
The ECCTA implementation roadmap is designed to help company directors, shareholders, secretaries and administrators track the timetable for reform. It acts both as a checklist for existing changes and a practical reference point to track the expected timing of upcoming changes.
This roadmap references the headline points of the ECCTA only. Further detailed information can be found in our Checklist of Headline Points for the ECCTA here.
Why Companies Need This Roadmap
The ECCTA introduces significant changes to the legal and regulatory framework for companies. A clear implementation roadmap helps users to:
- monitor both when key provisions came into force and are expected to come into force;
- prepare for changes to Companies House procedures;
- prepare for changes to company accounts;
- review processes and implement changes as they relate to revised Companies House filings and procedures; and
- communicate legal changes to company directors and shareholders, particularly in relation to identity verification requirements.
Important Note on the ECCTA Implementation Dates
Some implementation dates may change where further regulations, secondary legislation, or government guidance are still awaited. This roadmap reflects the latest available information at the time of publication and should be used as a practical planning tool alongside future updates.
