Articles Of Association In The UK: What You Need To Know

If you’re running a limited company in the UK, your Articles of Association are one of the most important documents you’ll ever sign off on.

They set the “house rules” for how your company is run, who can make decisions, how shares move around, and what happens when things don’t go to plan.

Get them right, and you’ll save yourself disputes, delays and cost down the track. Get them wrong (or leave them as the default) and you could be stuck with rules that don’t match how you actually want to operate.

In this guide, we’ll explain what company Articles are in the UK, how the standard “model” Articles compare to bespoke provisions, and exactly what small businesses might want to include and update as they grow.

What Are Articles Of Association In The UK?

Under the Companies Act 2006, the Articles of Association (often just “Articles”) are the internal rulebook for your company.

They’re a binding contract between:

• the company and each shareholder, and
• each shareholder and the other shareholders.

In plain English: they set the rules everyone agrees to follow for running the company and dealing with shares.

Key points to know:

• All companies must have Articles. If you don’t draft your own, you’ll automatically adopt the government’s “Model Articles” on incorporation.
• They cover core governance areas like directors’ powers and decision-making, issuing and transferring shares, dividends, meetings and written resolutions.
• They have legal effect like a contract, so day-to-day operations and disputes will refer back to what your Articles say.
• You can change your Articles later by a 75% shareholder vote (a “special resolution”) and filing the new version at Companies House.

For small businesses, the biggest trap is assuming the default rules fit your real-world needs. Often they don’t - especially around how shares can be transferred, how founders can be protected, and how deadlocks are resolved.

Model Vs Bespoke Articles: Which Is Right For Your Small Company?

When you register a private company limited by shares, you can either rely on the standard “Model Articles” or adopt bespoke Articles tailored to your business.

What The Standard Articles Of Association Cover

The standard Articles of Association (the “Model Articles” for private companies limited by shares) are short and broadly drafted. They’re designed to be a generic default so a company can legally function from day one.

They typically include:

• How directors can make decisions (board meetings and written resolutions)
• Share allotment basics
• General meeting and shareholder decision rules
• Limited rules on share transfers
• Dividend and reserve provisions

They’re fine for a simple, dormant or single‑shareholder company, but they’re light on controls that growing small businesses often need.

When Bespoke Articles Make Sense

Most founder-led companies benefit from a set of tailored Articles that reflect how you want to run things in practice. Bespoke Articles can help you:

• Control who can become a shareholder (strong pre-emption and transfer restrictions)
• Deal with departures (good leaver/bad leaver rules and buy-back mechanics)
• Avoid stalemates (deadlock and chair casting vote options)
• Clarify director powers and reserved matters requiring shareholder approval
• Streamline decision-making with modern written resolutions and notice provisions
• Prepare for investment by aligning with investor expectations and class rights

If you’re not sure whether to stick with model Articles or adopt bespoke, an Articles of Association Review is a simple way to check for gaps and risks against your goals.

What Should UK Companies Include In Their Articles?

Every business is different, but these are the areas small companies often refine or add to their Articles.

1) Shares, Pre‑Emption And Transfers

Think ahead about how shares can be issued, moved or sold, because that’s where many disputes start.

• Pre‑emption on allotment: Protect existing holders from dilution by giving them first refusal on new share issues. This ties into your plan for future fundraising and how you allocate shares among founders and early team members.
• Pre‑emption on transfers: Require any selling shareholder to offer shares to existing holders first, on the same terms.
• Drag and tag: While these are often in a Shareholders Agreement, some companies include drag-along/tag-along rights in the Articles so they bind future shareholders automatically.
• Compulsory transfers: For leavers or breach scenarios, set out when shares must be offered for sale and at what valuation.

2) Leaver Provisions And Buy‑Backs

If a founder or key employee leaves, what happens to their shares? Bespoke Articles commonly include leaver provisions to let the company or remaining shareholders buy back those shares with a fair valuation formula. You can also reference processes for redeeming shares or buying them back where permitted by law.

3) Classes Of Shares And Rights

As you grow, you may want different share classes (e.g. A and B shares) with different voting or dividend rights. Your Articles should clearly state class rights and the process for varying them, in line with the Companies Act 2006 rules on class variation.

4) Director Powers And Decision‑Making

Clear rules for how the board operates will save time and reduce friction. Consider provisions on:

• Appointing and removing directors (beyond the default statutory route)
• Quorum and chair casting votes
• Written board decisions and records (paired with well‑kept board resolutions)
• Conflicts of interest and how to authorise them
• Matters reserved to shareholders

5) Shareholder Decisions And Meetings

Your Articles set out when shareholders must approve decisions and how those votes are taken (meetings vs written resolutions). Knowing when you need a simple majority vs a 75% threshold is essential, and it helps to align your Articles with how you manage ordinary vs special resolutions in practice.

6) Dividends And Distributions

Make your dividend rules workable and clear, including interim vs final dividends, record dates, and how to handle unclaimed dividends. Also consider when profits should be retained for growth.

7) Objects And Restrictions

Most companies now have unrestricted objects (so you can trade freely) - but you can restrict objects if your business needs tight focus. If you add restrictions, make sure they won’t block reasonable pivots or new revenue lines.

8) Administrative And Modernisation Tweaks

Small drafting tweaks can make day-to-day governance smoother:

• Modern notice and communication rules (including email)
• Clean written resolution mechanics
• Clear, practical quorum rules for both board and shareholders

Articles Vs Shareholders Agreement: How They Work Together

Your Articles and your Shareholders Agreement should complement each other. They’re not duplicates, and each has a distinct job.

• Articles: Public document filed at Companies House. Binds the company and all shareholders. Contains core governance rules and share mechanics that need to apply to anyone who becomes a shareholder.
• Shareholders Agreement: Private contract between the company and its current shareholders. It can go into more commercial detail (e.g. funding obligations, information rights, voting arrangements, drag/tag, restrictive covenants, and dispute resolution).

If there’s a conflict, courts look closely at the wording - but practically, you should align the two to avoid contradictions. For example, if your Shareholders Agreement reserves certain decisions to a super‑majority, mirror that concept in the Articles for consistency. If you don’t have one yet, getting a tailored Shareholders Agreement in place alongside your Articles is a smart move for risk management.

How Do You Change Your Articles Of Association?

Changing your Articles is a formal process under the Companies Act 2006. Here’s a straightforward roadmap.

Step 1: Decide The Changes

Work out exactly what you want to change, add or remove - and whether you’re replacing the Articles entirely. It’s worth getting a legal review to make sure the drafting does what you intend and doesn’t conflict with other rules or investor expectations.

Step 2: Get Shareholder Approval

You must pass a special resolution (at least 75% of votes in favour) to adopt or amend Articles. If you’re not used to the thresholds and notice requirements, it helps to refresh how special resolutions work."

Many companies pass shareholder decisions by written resolution rather than holding a meeting. If you’re preparing a template for routine approvals, a simple ordinary resolution template can also sit alongside your governance toolkit (noting that Articles changes still need a 75% vote).

Step 3: File With Companies House

Once approved, file the amended Articles with Companies House within the required timeframe (usually 15 days). The updated Articles then become the binding version on the public record.

Step 4: Update Your Internal Records

Make sure all directors and shareholders have the updated Articles. If you use cap table or board software, upload the new version there as well. Align your internal processes (e.g. board packs, notices, delegations) with the updated rules.

When To Plan A Change

It’s common to update your Articles when:

• You bring on external investors or implement employee option schemes
• Founders want tighter transfer controls or leaver protections
• You introduce new share classes with different rights
• You need to fix gaps, inconsistencies or outdated procedures
• Share capital actions are on the horizon (e.g. buy‑back or redemption) and the Articles need to support those processes

Common Pitfalls For Small Companies (And How To Avoid Them)

1) Leaving The Default Rules In Place Too Long

Model Articles are intentionally generic. If you grow, bring in co‑founders, or plan to raise funds, review them early so you can avoid firefighting later.

2) Weak Transfer Controls And No Leaver Provisions

Without strong pre‑emption and leaver rules, shares can end up with people who aren’t aligned with your business. That creates governance headaches and may scare off investors.

3) Mismatch Between Articles And Shareholders Agreement

If your private Shareholders Agreement says one thing and your Articles say another, you’re setting the stage for arguments. Keep them aligned and updated together.

4) Failing To Plan For Capital Actions

If you’re contemplating a buy‑back or redemption, check your Articles well in advance. Some actions (like certain buy‑backs) require specific authorisations and processes. Clarify the route for redeeming shares or other capital reductions and line up the right shareholder approvals.

5) Skipping The Paper Trail

Articles are only part of the picture. Make sure the board and shareholders properly authorise your decisions and that you keep clean records. Consistent use of board resolutions and shareholder resolutions will help you demonstrate compliance if challenged.

6) Not Considering PSC And Compliance Interactions

Changes in ownership or control triggered by your Articles may also affect reporting of People with Significant Control (PSC). Keep your PSC register up to date and consider how Articles-triggered transfers and allotments interact with PSC disclosure.

7) Ignoring Breaches Or Not Enforcing The Rules

If someone tries to transfer shares in breach of the Articles (for example, ignoring pre‑emption), act quickly to enforce your rights. You’ll typically have stronger footing if your company can show it has consistently applied the rules. Understanding the implications of a breach of Articles of Association will help you respond proportionately and protect the business.

FAQs: Articles Of Association UK

Do I Need To File My Articles With Companies House?

Yes. Your Articles are on the public record. If you change them, you must file the updated version (generally within 15 days of the resolution).

Can I Restrict Share Transfers In The Articles?

Yes. Strong pre‑emption and transfer controls are common in small private companies. They help you control who becomes a shareholder and on what terms.

What’s The Difference Between Articles And A Constitution?

In the UK, “Articles of Association” is the correct term for the company’s rulebook. Some other jurisdictions use “constitution” - in the UK context, your Articles serve that role.

Are Leaver Provisions Better In The Articles Or The Shareholders Agreement?

It depends. Articles bind all current and future shareholders, which is useful for enforcement. However, many businesses keep granular leaver rules in a private Shareholders Agreement for confidentiality. A blended approach is common.

Can I Add Different Share Classes Later?

Yes, provided your Articles support them and you follow the correct authorisations and filings. Have a clear plan for class rights before you issue new classes.

How Do Articles Affect Future Investment?

Investors will review your Articles closely. Clean, investor‑ready Articles can speed up deals. If you anticipate a raise, align your Articles with market norms ahead of time so your round isn’t delayed.

Do Articles Affect How I Allot Founder Or Team Shares?

Absolutely. Articles interact with pre‑emption, consent requirements, share classes and valuation mechanics. Before you re-balance or expand your cap table, sense‑check your Articles and your plan for allocating shares.

Getting Drafted Articles: Practical Tips

While it’s tempting to copy‑paste a template, your Articles are a high‑impact document worth getting right. A few tips:

• Start with the end in mind - think about who you want on the cap table, how decisions will be made, and what a clean exit looks like.
• Document what you already do - write your operational norms into the rules so reality and paperwork match.
• Avoid contradictions - align your Articles with your Shareholders Agreement and internal policies.
• Keep future actions in view - if you may do buy‑backs, redemptions or option schemes, ensure the Articles anticipate these.
• Update in phases - don’t wait for a funding round to scramble; adopt sensible improvements early.
