AccountsOS Launches Direct Companies House Filing for UK Directors and PSCs

AccountsOS has integrated direct filing capabilities for statutory company changes with Companies House, allowing UK limited companies to manage director appointments, office addresses, and persons with significant control (PSC) within its platform. For fintech professionals, this represents a significant step in the automation of corporate secretarial tasks through AI-driven accounting software.

What was announced

The new functionality allows users to handle several specific Companies House forms directly from the AccountsOS interface. These include AP01 for appointing a director, TM01 for removals, and AD01 for changing a registered office address. These director and office forms went live on 16 October. Following approval from Companies House, the platform also added support for PSC01, PSC04, and PSC07 forms on 19 October, which are used for adding, changing, or removing an individual person with significant control.

These new features sit alongside the confirmation statement and annual accounts filings that were already active on the platform. To ensure accuracy and compliance, every filing includes a mandatory review step; no data is submitted to the public register until a person manually checks and confirms the details. Once Companies House accepts a filing, AccountsOS automatically refreshes the company's directors, PSCs, and address information from the public register to ensure the internal records match the official government data.

The interface also features a dedicated page that displays the five specific duties Companies House mandates for directors. This section provides a live status for each duty and offers a direct way for users to act on them, ensuring that company officers remain compliant with their legal obligations while using the software.

The companies involved

AccountsOS positions itself as an AI accountant specifically designed for the UK limited company market. The firm focuses on automating the administrative and regulatory burdens that typically require manual intervention or expensive external accounting services. By integrating directly with Companies House, AccountsOS is moving beyond simple bookkeeping into the realm of corporate governance and statutory compliance.

The platform is designed to streamline the entire lifecycle of a UK business, from initial setup through to annual reporting and the ongoing maintenance of the public record. Its market position is defined by the use of artificial intelligence to handle tasks that were traditionally the preserve of human accountants, aiming to provide a more responsive and cost-effective solution for small to medium-sized enterprises (SMEs). The company has focused heavily on creating a conversational and accessible interface for financial management, leveraging modern AI models to interpret and execute complex regulatory requirements for its users.

What FF News has reported before

FF News has tracked the evolution of AccountsOS as it expands the capabilities of its AI assistant, Finn. In September 2026, we reported on the launch of AccountsOS Launches Finn: The AI Accountant Now Available via ChatGPT Plugin, which brought the service to the popular AI ecosystem. This was followed shortly after in October by the announcement that AccountsOS Launches Voice Access for Finn: The AI Accountant You Can Now Call, enabling users to interact with their AI accountant via telephone. These developments highlight a consistent trend of increasing accessibility and multi-modal interaction for AI-driven financial services within the UK market.

What this means

The move into statutory filings signals a shift for AI accounting platforms from simple data entry tools to comprehensive compliance engines. By automating the submission of AP01 and PSC forms, AccountsOS is directly challenging traditional corporate secretarial services and high-street accountancy firms. The industry is seeing a rapid consolidation of the "back office" where banking, accounting, and legal compliance merge into a single software layer. This puts pressure on traditional providers to justify their fees for routine administrative filings. The critical question for the sector is whether the "AI layer" provides enough added value in error-checking and guidance to remain essential as government portals themselves become more user-friendly.
