Equity funding in the UK: how it can fuel business growth

The short answer

Equity funding means selling shares in your business to raise capital. You get money and expertise with no repayments. You give up a share of ownership, some control, and a slice of your eventual exit.

The right funding is often the make-or-break factor in scaling a company. UK smaller businesses raised £12.3 billion in equity investment in 2025, according to the British Business Bank. London-based companies took 57% of it.

But equity funding is not right for every business. And who you take money from shapes how, when and for how much you eventually sell.

This guide covers how equity funding works, the options open to UK businesses, what it costs you, and how to raise it without boxing in your exit.

The key points

• Equity funding is capital in exchange for shares. There are no repayments, but your ownership is diluted.
• There are five main routes in the UK: angel investment, venture capital, private equity and growth capital, crowdfunding, and an IPO.
• For established businesses with £5M or more in revenue, growth capital and private equity are usually the relevant routes.
• Every institutional investor needs an exit. Taking their money starts the clock on yours.
• Before you raise, find out whether the business is ready to grow. The free Ready To Scale Scorecard takes about 10 minutes.

What is equity funding?

Equity funding, also called equity finance, is raising capital by selling shares in your business to investors.

Unlike a loan, there is nothing to repay and no interest. Investors make their return when the shares are worth more than they paid, usually when the business is sold or floated. That makes it attractive to businesses that want to grow faster than their own cash flow allows.

The trade-off is ownership. New shareholders mean a smaller share for you, and usually a say in the big decisions.

What types of equity funding are available in the UK?

There are five main routes. Which one fits depends on the size, stage and ambitions of your business.

Watch forCost, regulation and disclosure

1. Angel investment

Angel investors are wealthy individuals who put their own money into early-stage businesses. They often bring industry experience, contacts and mentoring alongside the capital.

The government encourages it through two schemes. Under the Seed Enterprise Investment Scheme (SEIS), investors can claim 50% income tax relief. Under the Enterprise Investment Scheme (EIS), it is 30%. From 6 April 2026 most companies can raise up to £10 million a year and £24 million in total under EIS.

The catch for established businesses: EIS money generally has to arrive within seven years of your first commercial sale, and the company needs fewer than 250 employees.

2. Venture capital

Venture capital (VC) firms invest in high-growth businesses, usually for equity and a seat on the board. It suits companies with a scalable model and a big market, particularly in tech, fintech and biotech.

Well-known UK names include Balderton Capital, Molten Ventures (formerly Draper Esprit) and Octopus Ventures.

3. Private equity and growth capital

Most relevant for established businesses

This is the route most relevant to an established, profitable business. Private equity (PE) firms take substantial stakes in mature companies to drive growth and increase long-term value.

There are two broad versions:

• Minority growth capital. The investor buys a smaller stake and you stay in control. BGF, which describes itself as the most active equity investor in the UK and Ireland, invests this way.
• Majority buyout. The investor buys control, often backing your management team. This is how many management buyouts are funded. At the larger end of the market, UK names include Apax, Hg and CVC.

4. Crowdfunding

Equity crowdfunding platforms such as Crowdcube and Republic Europe (formerly Seedrs) let you raise money from a large pool of investors, each taking a small stake. It is popular with consumer-facing businesses, because it raises funds and builds a base of customers who are also owners.

5. IPO (initial public offering)

An IPO means floating shares on a stock exchange to raise capital from institutions and the public. AIM, the London Stock Exchange's market for growing companies, is the usual route for businesses not yet ready for the Main Market. It brings access to large-scale funding, along with strict regulation and public scrutiny.

How does equity funding fuel business growth?

01

Faster expansion

You can scale operations, enter new markets and hire senior people now, without waiting for profits to fund it.

02

Strategic expertise

Good investors bring sector knowledge, operational experience and contacts. They have seen the common mistakes before.

03

A stronger competitive position

Extra capital pays for R&D, a better product and a bigger share of a crowded market.

04

No fixed repayments

Profits go back into growth instead of servicing loans.

Verne Harnish puts the underlying problem bluntly in Scaling Up: growth sucks cash. Equity funding is one way to feed it.

What are the downsides of equity funding?

Dilution. You own less of the business, so you receive less of the sale price when you exit.

Control. Investors normally ask for a board seat and a say over major decisions, such as taking on debt, hiring senior people or selling the company.

Their timetable. Institutional investors need to return money to their own backers, typically within three to seven years. That sets a deadline for a sale, whether or not it suits you.

Time and cost. A raise can absorb months of management attention, plus legal and advisory fees.

Example: what dilution looks like

Picture a business valued at £10 million. The owner raises £2.5 million of growth capital.

The figures are for illustration only.

Before the raise

£10 million

Value of the owner's share

Business value£10 million

Owner's share100%

After the raise

£10 million

Value of the owner's share

Business value£12.5 million

Owner's share80%

At exit, if the plan works

£20 million

Value of the owner's share

Business value£25 million

Owner's share80%

A smaller slice of a bigger pie can be worth far more. But if the growth does not come, the owner has sold 20% of the business for nothing gained. The investment has to be the thing that makes the pie bigger.

How does equity funding affect your exit?

This is the part most funding guides skip. An equity raise is not just a growth decision. It is the first move in your exit.

It starts a clock

Your investor's return comes from a sale or a float. Once they are in, an exit is no longer optional, and the timing is no longer yours alone. If that is new territory, start with when to begin exit planning.

It can be a partial exit

In some deals the owner sells part of their own stake, banks some of the value now, and keeps shares for a second sale later. That takes personal risk off the table without leaving the business.

It is a dress rehearsal for a sale

Investors check the same things a buyer will: owner dependency, financial reporting and client concentration. Fix them before the raise and you get better terms now and a better price later.

The terms matter as much as the valuation

Share classes, preference rights and who can force a sale all change how much of the exit price reaches you. A higher valuation on worse terms can leave you with less.

That is why growth, money and law need to be in the room together. At Exit Advisory Team that means Neale Lewis on scaling, Adam Rhodes on what you need from a deal, and Debra Martin on the legal structure. Meet the team, or read how to build your deal team.

Is equity funding right for your business?

Ask yourself five questions before you start.

1. Are you willing to give up equity and some control?
2. Do you have a scalable model with real growth potential?
3. Do you want an exit in the future, whether a trade sale, a buyout or a float?
4. Do you need expertise and connections, not just money?
5. Have you already freed up the cash inside the business?

If the first four are a yes, equity funding could be a strong fit.

The fifth is worth checking first. The cheapest capital is the cash you already have. The free Cash Acceleration Scorecard shows where you could free up cash before you sell a single share.

What should you do before you raise?

1. Know what the business is worth, and why. Investors pay more for the assets owners often overlook. See our post on maximising the valuation of your business.
2. Get the business investor-ready. Clean numbers, a management team that runs the day to day, and a spread of customers. That is the work in Maximise Value.
3. Decide what you want from the eventual exit. Work out your "Magic Number" and your preferred route before you sign anything. Our exit planning guide walks through it.
4. Choose the investor, not just the cheque. The right investor at the right time can transform a business. The wrong fit leads to misalignment and loss of control.

Common questions

What is equity funding?

Equity funding is raising capital by selling shares in your business to investors. There are no repayments. Investors make their return when the shares rise in value, usually at a sale or flotation.

What is the difference between equity funding and debt finance?

Debt is borrowed and repaid with interest, and you keep full ownership. Equity is not repaid, but you give up a share of the business and of its future value.

What is the difference between venture capital and private equity?

Venture capital backs young, fast-growing companies that may not yet be profitable. Private equity invests in established, usually profitable businesses, either as a minority growth investor or by buying control.

Do I have to give up control of my business?

Not necessarily. With a minority investment you keep the majority of the shares. Investors will still normally ask for a board seat and a say over major decisions.

Does taking equity funding affect selling my business later?

Yes. Your investor will need an exit, the terms you agree shape how sale proceeds are shared, and their timetable influences when you sell. Plan the raise and the exit route together.
