The Top 10 Most Valuable UK Companies in 2025
The UK investment market is in a turbulent place right now, with a 34% year-on-year drop in the value of deals in H1 2025. We’ve also seen a string of down rounds, including from The Hut Group and Atom Bank, whilst the stock trading app Freetrade, which saw its value slashed by 65% in 2023, recently exited by acquisition.
With the halcyon days of 2021 behind us, where interest rates were close to zero, we’re examining which companies are bucking these trends and securing the highest valuations in a volatile market.
To achieve this, we consulted the Beauhurst platform to analyse the most valuable UK companies that have raised equity in the past 12 months. By excluding companies that could have achieved a valuation prior to this date, we’re exhibiting only the most valuable companies that are succeeding in spite of the broader market slowdown.

What are the top funded companies in the UK based on annual turnover?
Using the same methodology as above, we’ve now sorted these companies to find the top three UK companies by turnover.
Topping the list is the retail giant and ex-unicorn The Hut Group with a turnover of £1.75b. To date, the company has secured 12 fundraisings worth a total of £1.18b, with the latest round — part equity and part loan — taking place in March 2025. The business has also made 34 acquisitions in its history, spun out two businesses, and secured two grants worth £2.69m.
Second on our list is car manufacturer and Formula One team, Aston Martin. Our figures reveal that the company registered £1.58b in turnover last year. In May 2025, the company raised £52.5m in follow-on investment from Yew Tree Consortium, bringing its total equity raised to £1.63b across nine rounds. In addition to this, the company has secured £13m from InnovateUK across 13 grants.
Inspired, a global consortium of private schools, takes the third spot with £931m in turnover.
What are the top funded companies in the UK based on GVA?
Using the same parameters as above, we then looked at the top companies in the UK based on their GVA (gross value added).
Inspired tops the list, reporting a gross value added (GVA) of £642m. The company operates across multiple sectors and has grown into one of the UK’s largest contributors to the economy.
In second position is Aston Martin, with a GVA of £523m, followed by The Hut Group, which posted £400m.
As a reminder, we calculate GVA via the GVA(i) formula, also known as the ‘income approach’. This means adding employee wages + operating profit (EBIT) + depreciation + amortisation together to deliver a final figure. You can read more about our GVA data here.
What are the top funded companies in the UK based on number of employees?
The number of staff that a business employs is also an important measure of their success.
Leading the dataset is Inspired, which employs 10.5k staff across its network. The group has rapidly expanded through acquisitions and now operates in multiple countries, offering education to students worldwide.
In second place is Dewhirst, with 10.3k employees. The company is a long-established clothing manufacturer and supplier, producing garments for international fashion and retail brands, with operations spanning design, sourcing, and large-scale production.
Cera takes the third spot, employing 9.04k staff. The technology-enabled healthcare provider offers homecare, telehealth consultations, and prescription services, with its digital platform allowing users to book appointments with nurses and carers on demand.
Looking to the future
The future of equity-backed businesses in the UK appears promising, poised to play a pivotal role in shaping and improving the country’s economic landscape.
These dynamic enterprises, often characterised by rapid expansion and innovation, are expected to contribute significantly to job creation, bolstering employment rates and fostering a culture of entrepreneurship.
As these businesses continue to push boundaries and embrace emerging technologies, they are expected to contribute not only to economic growth but also to the evolution of industries and the transformation of traditional business models.
