Two angels can write the same cheque into the same company on the same day and own a wildly different thing by the time it sells. Not because one negotiated a bigger slice - they might own identical percentages - but because one took ordinary shares and the other took preference shares. On the cap table they look like neighbours. In the payout queue they stand in different lines.
The share class is the quiet decision that sets your terms for everything that follows: who gets paid first, who gets to vote on what, and, in the UK, whether the taxman gives you anything back for the risk. It's worth getting straight before you sign.
What are ordinary shares?
Ordinary shares - the default class in almost every British company - are ownership in its plainest form. Each one usually carries a vote, an equal right to any dividend the company chooses to pay, and a right to a proportional share of the assets when the company is finally wound up or sold. Founders hold ordinary shares. Employees with options end up holding ordinary shares. And the earliest angels, particularly those claiming tax relief, typically hold ordinary shares too.
The defining feature of ordinary shares is where they sit in the order of payment: last. When a company is sold or wound up, ordinary shareholders are paid only after every prior claim - lenders, then any preference shareholders - has been satisfied. In a strong exit that hardly matters, because there's plenty to go round and the ordinary holders share fully in the upside. In a weak one it matters enormously, because there may be little or nothing left by the time the queue reaches them.
What are preference shares?
Preference shares - "preferred", in the American shorthand you'll hear in most rounds - are ordinary shares with extra rights negotiated on top. The shares themselves still represent ownership, but the holder has bargained for a better position, and the rights are written into the company's articles and the shareholders' agreement rather than being implied by default.
The headline right is the liquidation preference: the entitlement to take an agreed amount - very often one times the money invested - off the top of the sale proceeds before any ordinary shareholder is paid. It exists to protect the investor's downside. Put fresh capital into a risky young company and you'd rather get your money back than split a disappointing pot pro-rata with everyone else. A preference share is, at root, that protection made contractual. We've pulled the mechanics apart in a separate piece on liquidation preferences, because the multiples and the participating-versus-non-participating distinction do most of the real work.
On the cap table they look like neighbours. In the payout queue they stand in different lines.
Preferences rarely travel alone. The same share class often carries enhanced voting rights or a veto over certain decisions, anti-dilution protection that adjusts the holder's position if the company later raises at a lower price, and sometimes a fixed or cumulative dividend. So preference shares tend to mean more control as well as more money - a fuller seat at the table, not just a better place in the queue.
How do ordinary and preference shares compare?
The cleanest way to hold the two in your head is right by right:
- Payout order. Preference shares are paid first at exit, up to their preference amount. Ordinary shares are paid last, from whatever's left.
- Downside. Preference shares are built to protect capital in a poor exit. Ordinary shares carry the full downside - in a fire-sale they can be worth very little.
- Upside. In a large exit the gap narrows: non-participating preferred usually converts to ordinary to ride the upside, so both classes share in a genuine success.
- Control. Preference shares often carry stronger voting rights or specific vetoes. Ordinary shares carry the standard one-vote-per-share and little more.
- Dividends. Both can receive dividends, but early-stage startups rarely pay any. Where a dividend right exists, it's more often attached to the preference shares.
- Tax relief. This is the British twist, and it cuts the other way: SEIS and EIS relief generally needs ordinary shares. The protected class is the one that usually disqualifies you.
Why the share class decides your SEIS and EIS relief
Here's the part that catches British angels out. SEIS and EIS relief generally require ordinary shares carrying no present or future preferential right to dividends and no preferential right to the company's assets on a winding up. A liquidation preference is exactly that kind of preferential right - so the protected preference share that looks like the safer instrument is usually the one that fails to qualify for relief.
That puts the angel claiming relief in a deliberate trade-off. To keep the tax break, you take plain ordinary shares and accept sitting behind the preferred investors in the payout order. The relief is doing some of the work the preference would otherwise do - cushioning your downside up front rather than at exit - but only the part the rules allow, and only if you hold the shares long enough to keep it. There's no having both.
And the reliefs are worth holding onto. SEIS gives 50% income tax relief on up to £200,000 of investment in a tax year, with a three-year minimum hold; gains on the shares are exempt from capital gains tax if you've claimed the relief and held for three years, and relief can be carried back to the previous tax year. EIS gives 30% income tax relief on up to £1,000,000 a year - or £2,000,000 if at least £1,000,000 goes into knowledge-intensive companies - again on a three-year hold, with the same CGT exemption on the gains and the same carry-back option. Both schemes require the company to hold HMRC advance assurance before the round and to issue you an SEIS3 or EIS3 certificate afterwards, which is what you use to claim, and you generally need to be a UK taxpayer for any of it to be worth having.
The company-side qualifying conditions - gross assets, how much a company can raise, the knowledge-intensive variations - sit on the business, not on the share class, and some were adjusted for 2026. Check the figure that applies to a specific deal against HMRC's EIS guidance on gov.uk rather than a number you half-remember, and have the share class confirmed in writing before you commit, because it's the share rights - not the founder's intentions - that the relief turns on.
How should an angel read the share class?
Don't take "shares" at face value on a term sheet - find out which class. Ask three things. What class am I being offered, ordinary or preference, and in plain English what rights come with it? Where does it put me at exit - ahead of the ordinary holders, behind a preference stack, or sharing the bottom of the queue? And does it qualify for the relief I'm relying on - if SEIS or EIS is part of why the numbers work, the shares almost certainly need to be ordinary with no preference attached. The answers are in the articles of association and the shareholders' agreement, not the pitch deck.
A word on what this article is and isn't: it's general information, not financial or investment advice. Share rights live in binding legal documents and the tax rules around share classes can change. Before you commit to a deal, take advice from an FCA-regulated adviser and a solicitor, and confirm the current tax position with HMRC on gov.uk.
Frequently asked questions
What is the difference between ordinary and preference shares?
Ordinary shares carry the basic rights of ownership - a vote, a share of dividends if any are declared, and a slice of whatever is left at the end after everyone with a prior claim has been paid. Preference shares carry extra rights agreed in advance: most importantly a liquidation preference, which puts the holder ahead of ordinary shareholders for an agreed sum when the company is sold or wound up. Preference shares sit in front of ordinary shares in the payout queue; ordinary shares sit at the back.
Which type of share does an angel investor usually get?
It depends on the round and on whether tax relief is in play. Angels investing at the earliest seed stage, and especially those claiming SEIS or EIS relief, typically receive ordinary shares, because the reliefs generally require ordinary shares with no preferential right to your money. Venture funds leading priced rounds usually take preference shares. In the same company an angel can end up holding ordinary shares while a later fund holds preferred, which changes who is paid first at exit.
Why can preference shares break SEIS or EIS relief?
Because SEIS and EIS relief generally require ordinary shares that carry no present or future preferential right to dividends and no preferential right to the company's assets on a winding up. A liquidation preference is exactly that kind of preferential right, so shares carrying one will usually fail to qualify. Angels who want the relief typically take plain ordinary shares and accept a weaker position in the payout order. This is general information, not advice - confirm the current rules on gov.uk.
Do preference shares always pay a dividend?
No. In most early-stage UK startups, preference shares are about exit economics and control rather than income, and no dividend is paid because the company is reinvesting everything. Some preference shares carry a fixed or cumulative dividend right, common in later-stage or more debt-like instruments, but the typical venture preference share an angel meets at seed or Series A is non-dividend-paying in practice. Read the articles of association and the share rights to see what actually applies.
Are preference shares better than ordinary shares?
Neither is simply better - they protect different things. Preference shares offer downside protection and more control at exit, which suits an investor putting fresh capital into a risky company. Ordinary shares carry no payout priority but are the class that qualifies for SEIS and EIS relief, and they share fully in the upside of a strong exit. The right comparison is what each gives up: preference trades away the tax relief, ordinary trades away the priority. This is general information, not financial advice.
