Company Secretary Duties in the UK: A Complete Guide for 2026
15 August 2026
Learn the legal duties and responsibilities of a company secretary in the UK, from statutory filings to board support. Essential guide for 2026.
What is a company secretary and when is one required?
In the UK, the role of company secretary is defined under the Companies Act 2006. A company secretary is an officer of the company, responsible for ensuring that statutory and regulatory obligations are met. While public limited companies (PLCs) must appoint a company secretary, private limited companies are not legally required to have one. However, many private companies choose to appoint a secretary to manage administrative duties and ensure good governance. The secretary is not a director, but acts as a key advisor and administrator, bridging the gap between the board and compliance requirements. Understanding whether your company needs a secretary is the first step to fulfilling this crucial role.
Core statutory and compliance duties
The company secretary’s primary responsibility is to keep the company compliant with the Companies Act 2006 and other regulations. This includes preparing and filing annual accounts, the confirmation statement, and other mandatory returns with Companies House. The secretary must also ensure that events such as changes in directors, share allotments, or registered office addresses are filed within the prescribed time limits. Additionally, they handle notifications of significant changes, such as the appointment or resignation of auditors, and maintain up-to-date knowledge of filing deadlines. Failure to meet these obligations can result in fines, criminal penalties, or even the striking off of the company, making the secretary's role vital to corporate survival.
Board and governance support
Beyond statutory filings, a company secretary provides essential support to the board of directors. They plan and organise board meetings and general meetings, ensuring proper notice is given according to the company’s articles. During meetings, the secretary takes accurate minutes, records resolutions, and advises on procedural matters, including quorum requirements and voting rights. They also help implement board decisions by drafting agreements, managing communication with shareholders, and ensuring that corporate governance best practices are followed. In listed companies, the secretary often plays a more prominent role, advising on the UK Corporate Governance Code and compliance with the Financial Conduct Authority’s listing rules. This function ensures that the board operates efficiently and within the law.
Maintaining registers and records
A key duty of the company secretary is to maintain statutory registers and records. This includes the register of members, register of directors, register of secretaries, and register of charges (mortgages). Under the Companies Act 2006, these registers must be kept at the company’s registered office or a single alternative inspection location, and updated within specific timelines. The secretary is also responsible for keeping the Register of People with Significant Control (PSC register) up to date, recording any changes in ownership or control. Additionally, they must manage records of resolutions and meetings, and ensure that all documents are available for inspection by shareholders and authorised authorities. Accurate record-keeping is not just a legal requirement; it is essential for transparency and trust in the company.
The changing role and practical tips for 2026
In 2026, the role of company secretary continues to evolve, driven by digital transformation and regulatory reform. Companies House is implementing major changes under the Economic Crime and Corporate Transparency Act 2023, including identity verification for directors and enhanced data-sharing powers. As a result, secretaries must stay ahead of these changes by using online filing systems, ensuring that company records are accurate and up-to-date. Practical tips include setting up electronic reminders for filing deadlines, conducting regular compliance audits, and seeking professional development through organisations like the Institute of Chartered Secretaries and Administrators (ICSA). For private companies without a statutory secretary, outsourcing this role to a professional firm can be a cost-effective way to maintain compliance and focus on business growth.
