Farzana Haque, 29 June 2023

It’s been hard to ignore the staggering decline in startup valuations over the last few quarters. With high-interest rates, examples like Klarna’s remarkable 85% drop in valuation last year have raised concerns among investors and entrepreneurs alike. Against this backdrop of a fluctuating market, we wondered which companies in the UK currently have the highest valuations. So, we dug into our valuation data to uncover the 10 companies leading by valuations. 

By looking at private UK companies with an equity finance round between 1 June 2020 and 31 May 2023, we’ve ranked the top 10 high-valued companies based on pre-money valuation.

What are the top companies in the UK based on annual turnover?

We track every private company in the UK. Using this data, we’ve taken a look at private UK companies with an equity finance round between 1st June 2020 and 31st May 2023. We’ve then ranked the top ten based on annual turnover. At the very top of the list is Monzo, with a total turnover of over £517m. The app-based challenger bank has secured 14 fundraisings to date, worth £927m. It also received two grants from Innovate UK, the most recent of which was in October 2022.

Second on the list is Amazon Filters, a Surrey-based business that manufactures and supplies filtration equipment. Their turnover came to just over £130m, and to date, they have received £1.5m across two fundraisings.

Oncologica came in third on our list, with over £120m in turnover during the selected dates. This company provides a range of precision Oncology services, addressing the demand for personalised cancer medicine. They have gone through two rounds of fundraising, receiving a total of £850k.

What are the top companies in the UK based on annual profit?

Using the same parameters as above, we then looked at the top companies in the UK based on their annual profits. Somewhat surprisingly, there were only eight companies in total that announced profits in this data set. Oncologica took the top spot, with close to £21.5m in annual profit between 1st June 2020 and 31st May 2023, closely followed by Amazon Filters with just over £16m. In third place were Veeqo, a software development company focusing on building inventory and fulfilment platforms. Their annual profit came in at just over £9m, with £7,18m secured over 14 fundraisings, and a further £500k grant received from the Welsh Government in 2017. This company was acquired by Amazon in March 2022, and is no longer tracked by Beauhurst for this reason.

What are the top 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. In looking at this data set, we can see that Caffe Nero is right at the top of the list, with over 3,600 members of staff. The Italian coffee chain has more than 600 locations in the UK, and has been named in a number of high growth lists since 2013 (the most recent being the Fast Track Top Track 250 in September 2020.
