Special Resolutions: Decisions That Need 75% Approval in the UK

Most shareholder decisions in a UK company can be made with a simple majority. But when a decision is big enough to change the company’s “rules”, reshape shareholder rights, or alter the company’s capital structure, UK company law often requires a special resolution - a higher bar of at least 75% approval.

For small businesses, special resolutions usually pop up when you’re fundraising, changing your Articles, issuing new shares, doing a rebrand, or tidying up your share capital before a transaction. The vote itself is only half the job - special resolutions come with formality and filing requirements, and getting the process wrong can cause delays (or disputes) later.

What is a special resolution?

A special resolution is a shareholder resolution passed by a majority of not less than 75%.

How the 75% works depends on how you pass it:

• At a general meeting, it’s based on the votes actually cast (for example on a show of hands or a poll, depending on how voting is taken).
• As a written resolution (private companies), it’s passed if members representing at least 75% of the total voting rights of eligible members agree - it’s not just 75% of the people who bothered to reply.

One compliance point that trips people up: if you’re proposing a special resolution, your notice or written resolution text needs to state that it’s being proposed as a special resolution.

Why does the law make you hit 75%?

Because special resolutions are usually reserved for decisions that can materially affect the company’s constitution or shareholder rights. Requiring 75% is meant to stop major changes being pushed through by a narrow majority.

In real life, the 75% threshold matters most when the shareholding is split (for example, 50/50 founders) or where a minority shareholder holds more than 25% and can block special resolutions. It also matters because your Articles and your shareholders’ agreement can raise the bar even further - the Companies Act is often the minimum.

Decisions that commonly need a special resolution

There isn’t a single tidy “master list” that covers every scenario, but these are the most common special-resolution moments for UK SMEs.

Amending your Articles of Association (and other constitutional changes)

If you want to change the company’s Articles - for example, adding share transfer restrictions, introducing leaver provisions, creating new share classes, changing decision thresholds, or tightening director/shareholder controls - you generally need a special resolution.

This is one of the most common reasons small businesses need a special resolution, especially around investment rounds and co-founder fallouts.

Changing the company name

A company can change its name by special resolution, or by another method if the Articles provide for it.

Practically, most companies handle name changes via special resolution because it creates a clear paper trail and matches the standard Companies House process.

Reducing share capital (often a “tidy-up” before a transaction)

Private companies limited by shares can reduce share capital by special resolution supported by a solvency statement (as an alternative to the court-approved route).

This is usually relevant where you’re cleaning up the balance sheet, simplifying the capital structure, or dealing with legacy share issues before fundraising or exit.

Disapplying statutory pre-emption rights (issuing shares without offering them first)

If you want to issue equity securities without first offering them to existing shareholders pro-rata, you’ll often need a special resolution (or an Articles-based mechanism) to disapply statutory pre-emption rights.

This is a very common step in fundraising and employee equity, and it needs to be aligned with the directors’ authority to allot shares (and your shareholders’ agreement, if you have one).

Varying class rights (where you have different share classes)

If your company has different classes of shares, changes to the rights attached to a class often require class consent - typically either written consent from holders of at least 75% in nominal value of that class, or a special resolution at a separate class meeting (unless your Articles set a different procedure).

This is one of those areas where founders get surprised: you may need both (1) a special resolution to amend the Articles generally and (2) a separate class approval process.

Voluntary winding up (closing the company)

A company may be wound up voluntarily by resolution under the Insolvency Act framework. In a members’ voluntary winding up, the resolution is commonly a special resolution route, and there are additional steps like advertising the resolution in The Gazette within the required timeframe.

Winding up is a specialist area, but the key point for SMEs is: this isn’t just “stop trading and walk away” - it’s a formal process with prescribed steps and deadlines.

Meeting vs written special resolutions: which is better?

For many private companies, written resolutions are the simplest way to get a clean approval record without the admin of a meeting. Meetings can be more useful where you expect debate, negotiation, or contested votes - or where your Articles or shareholders’ agreement steer you toward a meeting process.

Either way, the process needs to match:

• the Companies Act minimum requirements, and
• anything stricter in your Articles/shareholders’ agreement.

Filing and paperwork: don’t skip this part

Special resolutions are a classic “the vote passed, so we’re done” trap.

A copy of applicable resolutions must be sent to Companies House within 15 days after they are passed (or made).

And where you’re changing the Articles or other constitutional documents, you’ll typically need to file the updated documents too. If you don’t, you can end up with uncertainty over what rules actually govern the company - which is the last thing you want mid-fundraise or mid-dispute.

The takeaway

Special resolutions are the 75% vote reserved for decisions that change the company’s foundations: the constitution, shareholder rights, capital structure, and major structural moves like name changes, capital reductions, class rights variations, or winding up.
