Growth equity has become one of the most active corners of British private capital, with £5.5 billion invested into UK headquartered companies during 2025, up from £3.8 billion the year before, according to UK Private Capital, the industry body formerly known as the BVCA. More investors now want to back companies that have finished experimenting and are ready to grow.

Growth equity sits between venture capital and the buyout. It pays for expansion, acquisitions, a first office abroad or a serious upgrade to technology, and it usually does so through a minority stake. Founders keep control, the business avoids acquisition debt, and the company gains a backer with more money to put in when the plan works.

The question facing a good British business has therefore changed, it is no loner whether the funding exists, but which partner to choose, and on what terms.

Why the middle ground works so well

Companies past product-market fit used to face an awkward choice. Venture money is priced for uncertainty and dilutes accordingly, while a buyout usually means handing over the keys. Neither option suits a profitable company with a ten year plan and a founder who wants to see it through.

Growth equity fills that gap nicely, as the investor is buying into a business where customers have already voted, so the conversation moves away from guesswork and towards practical questions. What would another 50 salespeople do to revenue, how fast could a European office break even, which three acquisitions would tidy up a fragmented market.

That leads to a different sort of relationship. A minority investor cannot impose much, so their value shows up in board meetings, in useful introductions and in their willingness to write a second cheque. Good ones earn their seat, and boards are well placed to judge them on exactly that.

Money with somewhere to go

British private capital funds raised £58.7 billion during 2025, comfortably ahead of the £34.8 billion raised the year before and the third highest total on record. Mid-market managers did much of the heavy lifting. Bridgepoint, IK Partners, Oakley Capital and MML Capital all closed funds, several of them reaching their limits ahead of schedule.

Fundraising totals rarely stir a company board, though perhaps they should. A manager who has just closed a fund has a set period in which to invest it, and that creates healthy competition for well run businesses. Company owners see the benefit in valuations, in flexible deal structures and in how quickly an investor moves when something good comes along.

Overseas appetite adds to the picture. European investors, including UK institutions, provided 42% of funds raised in 2025 against 33% the year before, with North American money contributing over a quarter. British mid-market managers are being funded by the world, and British companies are the ones who gain.

“Mid-market firms had a robust year for fundraising in 2025 as investors prioritised funds that back businesses with strong growth potential, often located outside the capital. These businesses act as lynchpins for local economies, creating high quality jobs and supporting supply chains.”

Control stays where it belongs

BGF offers a clear picture of the model at work. The investor passed £5 billion deployed in 2026, having backed more than 650 companies since 2011, and takes minority stakes of up to 40% without using debt to drive returns. It invests from an evergreen balance sheet, so there is no fund life counting down and no exit forced on a business at an unhelpful moment.

Founders feel that difference, a company can take investment, put it to work, then take more when growth earns it, with no clock shaping decisions in year four. The firm has put over £1 billion into follow-on funding, and that money often decides whether a good business becomes a large one.

Companies in the portfolio have added £8.2 billion in revenue growth and created more than 35,000 jobs, while exits since 2016 have produced a 22.6% gross internal rate of return and a 2x money multiple. The sale of Oxford medical technology business OrganOx at a $1.5 billion valuation in 2025 shows how high the ceiling goes for a company that scales well.

Location matters here too, around 74% of the firm’s capital has gone to businesses outside London and the South East, and it has pledged more than £3 billion to British companies over the next five years, including at least £300 million for female powered businesses through the Invest in Women Taskforce.

Pension money brings patience

Seventeen of the largest workplace pension providers signed the Mansion House Accord in May 2025, agreeing to put at least 10% of defined contribution default funds into private markets by 2030, with half of that going to UK assets. Signatories include Aviva, Legal & General, Nest, Phoenix Group and the Universities Superannuation Scheme. The Treasury expects around £25 billion to reach UK investments as a result.

Pension capital is patient by design, measured over decades and matched to obligations that fall due long after any five year plan has run its course. A manager backed by it can hold steady through a slower trading year and support an acquisition that takes time to pay off.

UK private capital funds returned 15.8% a year over the decade to the end of 2025, against 8.4% for the FTSE All-Share, and that record is why allocations keep rising. For a management team, steady institutional demand means the money is likely to still be there when the next round comes.

Where the advantage sits

Preparation is what separates a smooth raise from a slow one. Growth investors look closely at repeatable revenue, sensible unit economics, the strength of the team below the founder and the quality of monthly reporting. A board that puts its numbers in order a year ahead of a process tends to get better terms than one starting the week a term sheet lands.

Regional businesses hold a stronger hand than many of them realise. Mid-market managers are looking well beyond the capital, pension money arriving under the accord leans towards UK assets, and 57% of the businesses backed by private capital last year sat outside London. A well run company in Leeds or Bristol is competing for attention in a much smaller field.

The wider gain reaches far beyond the companies signing term sheets. Private capital now backs over 13,000 British businesses employing 2.5 million people, and contributes close to £200 billion a year to the economy, or around 7% of GDP, up from 6% in 2023. Growth equity is the part of that picture aimed squarely at firms with a working model and room to expand, which is where new jobs and stronger supply chains tend to follow. British business has the ideas and the trading record to justify the interest, and the money is arriving to match.
