Companies House P&L rules

Opening the Books, Opening the Floodgates? UK P&L Rules and Disputes Ahead

New UK disclosure rules under the Economic Crime and Corporate Transparency Act 2023 will require micro and small companies to begin submitting profit and loss (P&L) accounts to Companies House starting 1 April 2027, ending their current option to file abridged accounts CDR News

Key highlights:

Scope of change: Abridged accounts currently shield sensitive financial details like profit margins or supplier relationships. New rules will expose P&L data even for very small entities, which include companies with turnovers under £15M (small companies) or under £632K (micro‑entities) CDR News+1

Drivers of reform: The move is meant to enhance transparency, clamp down on economic crime, and improve data quality and risk assessment for lenders, regulators, and investors CDR News+1

Litigation implications: With P&L data now public:

Creditors can better assess a firm’s ability to pay.

IP rights holders may more easily pursue an account of profits.

Minority shareholders may spot suspicious financial practices, like excessive director remuneration, that could trigger shareholder disputes.

Forensic accountants gain richer data to identify anomalies and benchmark financial performance CDR News+1

.

Potential risks:

Financial filings may be up to 21 months old, reducing their relevance in fast‑changing situations.

Most micro and small company accounts remain unaudited, raising concerns about reliability.

The implementation remains under review; reports suggest a possible exemption for firms with turnover under £10.2M, though nothing is confirmed as of July 2025 CDR News+1

.

Bottom line: While the shift towards mandatory P&L disclosures for smaller firms will elevate transparency and support informed decision-making, it may also fuel disputes—particularly around enforceability, IP, and shareholder rights. Stakeholders should stay alert as this unfolds toward April 2027.
