How to Legally Appoint a Company Secretary: Qualifications and Requirements for UK Businesses

Thinking about growing your business, making your company structure more robust, or just handling compliance more efficiently? If so, you might be considering appointing a company secretary. Whether you’re running a brand-new limited company or shifting from a sole trader setup, knowing how and when to appoint a company secretary can make a real difference to your operations-and peace of mind.

While appointing a company secretary isn’t mandatory for all UK businesses, getting this step right helps ensure your company is legally protected and set up for smooth growth. In this guide, we’ll break down everything you need to know about company secretary appointments-including qualifications, step-by-step requirements, and how these roles fit with your overall business goals.

Let’s demystify the process of appointing a company secretary so you can focus on running-and growing-your business with confidence.

What Is a Company Secretary and Does Your Business Need One?

First up, it’s worth clarifying what a company secretary actually does-and who really needs one.

A company secretary is essentially a key officer who supports the directors in keeping your company compliant. They look after things like:

• Making sure you keep proper company records
• Filing annual returns and confirmation statements with Companies House
• Arranging board meetings and taking minutes
• Communicating with shareholders
• Staying up to date with legal and regulatory obligations

For public limited companies (PLCs), having a company secretary is a legal requirement. For most private limited companies, it’s optional-but many businesses choose to appoint one anyway to share the compliance workload, especially as the business grows.

If you’re unsure whether your business needs a company secretary, it comes down to your company’s size, operations, and appetite for risk. For smaller businesses, a director often takes on these duties themselves, but for larger or fast-growing companies, appointing a company secretary can free up directors’ time and minimise compliance mistakes.

Who Can Be a Company Secretary in the UK?

The next question most business owners ask is: who can be a company secretary?-and do they have to be legally qualified?

For private limited companies in the UK, the law is quite flexible:

• You can appoint an individual or a corporate entity (such as an accountancy firm or company secretarial service provider)
• The company secretary doesn’t have to be a director or shareholder
• They can also be a director-but a sole director can’t also serve as the sole company secretary
• There are no strict qualification requirements for private companies (that changes for public companies-more on that below)

However, you should always pick someone who understands company law, is organised, and can keep up with deadlines and filing obligations. For example, appointing your bookkeeper or an external governance professional is common.

For public limited companies (PLCs), it’s a different story: the law (Companies Act 2006) requires a secretary with formal qualifications or proven experience. You’ll need someone who:

• Is a member of a professional body, like the Chartered Governance Institute UK & Ireland
• Is a barrister, advocate, or solicitor
• Has held the office of secretary of a PLC for at least three of the last five years
• Has other qualifications or experience the directors deem appropriate

What Are the Key Company Secretary Qualifications for UK Businesses?

While there are no mandatory exams or certificates for secretaries of most private limited companies, there are some basic requirements to tick off:

• The secretary must be at least 16 years old
• Must not be an undischarged bankrupt (unless court permission has been granted)
• Must not have been disqualified from acting as a company secretary or director
• A corporate secretary must be a legitimate legal entity (e.g. a registered firm)

It’s also best practice to choose someone who:

• Has experience with statutory filings-like annual confirmation statements, Companies House filings, and meeting minutes
• Is familiar with the Companies Act 2006 and relevant compliance requirements
• Can communicate well and keep accurate records

For larger businesses, or anyone running a PLC, you’ll need to check that your secretary’s qualifications are formally recognised by a professional body or through legal experience as outlined earlier.

How Do You Appoint a Company Secretary? Step-by-Step Guide

Ready to appoint a company secretary? Here’s a practical step-by-step guide for UK business owners:

1. Check your company’s Articles of Association
   Before you start, verify if your company’s articles contain any specific rules about company secretary appointments. Some articles may set out requirements or restrictions-for instance, on who can hold the post or how they should be appointed.
2. Pass a Board Resolution
   The formal appointment of a company secretary should be approved by the board of directors. This usually involves a board meeting (or written resolution) with the secretary's details recorded in the company’s records.
   Not sure about board resolutions? See our guide on how to use board resolutions.
3. Update Statutory Registers
   Update your company’s official register (the company books) with the new company secretary’s name and details.
4. Notify Companies House
   Companies House must be informed of the new appointment within 14 days. You can do this online using the WebFiling service, or by posting Form AP03 (for an individual) or AP04 (for a corporate secretary).
   There is no cost for filing, but don’t miss the deadline-late or incorrect filings can cause compliance headaches and penalties.
5. Inform Stakeholders and Update Records
   Update any relevant stakeholders (shareholders, accountants, legal advisors). Update your letterhead, stationary, and website details where required.
6. Issue an Appointment Letter
   It’s best practice to provide the company secretary with a letter of appointment outlining their responsibilities, terms, and access to company resources.

This process also applies if you need to remove or replace a company secretary in the future-just follow the same steps in reverse and notify Companies House on time.

What Are the Key Duties and Responsibilities of a Company Secretary?

While the Companies Act 2006 doesn’t spell out an exhaustive to-do list for company secretaries, there are typical responsibilities they’ll need to manage, including:

• Maintaining the company’s statutory and compliance records
• Organising board meetings and shareholder meetings, including taking and filing meeting minutes
• Handling communications with Companies House (like annual confirmation statements, changes in directors or company information)
• Ensuring the company complies with legal and regulatory requirements-including data protection, employment law, and more
• Acting as the main point of contact between directors and shareholders

For a deeper dive into these compliance topics, read our guide on business regulations and compliance.

The role is strategic: a good company secretary ensures directors meet their legal duties, deadlines are never missed, and the company is well-positioned to deal with regulators or investors.

How Do You Remove or Change a Company Secretary?

There may come a time when you need to remove or replace your company secretary (for example, if they resign, retire, or you want to appoint someone with stronger qualifications).

Here’s what you should do:

• Check your company’s articles for any specific removal procedures
• Have your directors pass a resolution to remove the secretary
• Notify Companies House within 14 days-using WebFiling or Form TM02
• Update your company registers and communicate with any stakeholders
• Consider issuing a formal notice or letter confirming the change

Ensure all statutory registers and online details are immediately updated-mistakes or slow updates can lead to regulatory snags and confusion, especially in the run-up to investments or business sales.

Do You Need a Company Secretary Agreement or Board Resolution?

While there’s no strict legal requirement for having a written company secretary agreement, it’s strongly recommended. This agreement (or formal appointment letter) spells out the scope of the role, expectations for confidentiality, and what happens if things don’t work out.

You should also keep proper documentation of board resolutions appointing or removing the company secretary. These records may be needed for due diligence if you ever sell your business or bring in investors.

Need help drafting a tailored agreement or getting board paperwork in order? That’s where legal advice really makes a difference.

What Happens if You Get the Company Secretary Appointment Wrong?

While appointing a company secretary is a positive step, getting it wrong-or failing to file the right paperwork-can have consequences, including:

• Delays or refusals in key company processes (like opening a business bank account or securing investment)
• Penalties for late or incorrect filings with Companies House
• Legal disputes over the validity of board decisions or shareholder meetings
• Loss of good standing if the company’s compliance record is questioned

It’s always best to address these steps proactively, make sure your documentation is in order, and seek expert help if you’re ever unsure.
