Ty Nant named Wales’ fastest-growing private company by The Sunday Times

Ty Nant, the mineral water brand based in Bethania, is Wales’s fastest-growing private company, according to the fifth annual Sunday Times 100 rankings.

The list is published today online at thesundaytimes.com/100 and available as a supplement with the print edition of the newspaper this Sunday 7th June.

The annual ranking identifies and celebrates Britain’s 100 leading entrepreneurial businesses, and showcases the people behind these most dynamic private companies. The Sunday Times 100 excludes companies selling their own technology, which now feature in the sister table, The Sunday Times 100 Tech.

Ty Nant made £18.1 million in sales in the year to March, a staggering 91.80% average annual growth in the last three years. This mineral water brand is recognisable from its striking cobalt-blue bottles. It traces its beginnings to 1976 when a water diviner is said to have found a water source — “the purest he had ever tasted” — in Ceredigion, west Wales.

Thirteen years later, the Ty Nant mineral water brand was launched at the Savoy Hotel in London. In 2020, it was bought by the Sidhu and Nanua family, led by the entrepreneurs Raminder Sidhu, 70, Gurinder Sidhu, 46, and Bobby Nanua, 45. Sales more than doubled in the 12 months to March, helped by acquisitions, including the purchase last year of Strathmore Water from AG Barr.

The research for The Sunday Times 100 found on average the top 100 fastest-growing companies have increased their sales by 108% a year over the last three years to a combined £4 billion in sales. This figure is up by £600 million compared with the same table last year, with the 2025 cohort of top 100 fastest growing companies achieving £3.4 billion in sales.

In total these companies employ 13,700 people, having created 8,900 new jobs in the last three years, with almost all of them planning further hires in the next 12 months – equating to around 4,200 additional roles.

Out of the 100 companies featured in the ranking 45 are based in London, with the rest spread through-out the UK. This includes 14 in the northwest, 10 in the southeast, 8 each in the east of England and the Midlands, 5 in Yorkshire and the Humber, 4 in Wales, 3 in the southwest, 2 in Scotland and 1 in the northeast.

A record number 33 of the businesses have female founders, co-founders or chief executives: they include Michelle Laithwaite of FuelHub and Megan Rossi of Bio&Me.

Nearly three-quarters of the companies (72) were founded in the last decade – in 2015 or after. The oldest company on the list is Leeds-based Wilson Power Solutions. This third-generation manufacturer began life in 1946, when its founder, Richard Wilson, started selling flameproof equipment, pumps and motors. It is now led by Erika Wilson, 47, apprentice-turned-managing director. The company makes transformers — crucial components of the power grid that increase and decrease voltage. The group has also expanded overseas, with a factory in Chennai, India, and a transformer rental power business in Dubai.

The youngest companies on the list were founded in 2022, including the top company Goalhanger, beauty brand REHAB, and construction contractor City Grey.

Approximately half of the companies on the list trade internationally, including Ancient & Brave (No 7). The health supplements brand has expanded into markets including Germany, Spain and the US. Sales reached £53.7 million in the last year.

Jon Yeomans, business editor of The Sunday Times, said:

“Celebrating five years of The Sunday Times 100 shows the amazing variety of British businesses, led this year by the media producer Goalhanger taking the number one spot. The biggest trend over the last five years is the rise of consumer brands, with food, drink, fashion, and beauty companies now making up nearly half the list. 

Several businesses who have featured in the past, such as Huel and Applied Nutrition, have continued to grow and find huge success, from launching on the stock market to being bought out by global giants.” 

Mohammad Kamal Syed, Head of Private Bank and Wealth Management UK and Crown Dependencies, said:

“Britain’s fastest-growing private companies are built by founders with ambition, resilience, and a clear vision for the future. As founders scale, achieving the right outcome is about more than value – it’s about securing the long-term success of the business and its people.

At Barclays, we understand that no two journeys are the same. By bringing together expertise across Private Banking, Corporate Banking and Investment Banking, we provide founders with deep, real-time insight and tailored support as they navigate growth, investment and succession decisions.

Our continued support for The Sunday Times 100 reflects our commitment to backing Britain’s entrepreneurial businesses at every stage of their growth and celebrating the innovation and impact that they bring to the UK economy.”

To be included on the list companies have to be registered in the UK and be independent, unquoted and ultimate holding companies. Sales growth is measured by compound annual growth rate (CAGR) over the latest three financial years. Annualised sales have to exceed £250,000 in the base year and not show a drop from the penultimate to the latest year, in which total sales must exceed £5 million. The companies also need to make a profit in their latest year of trading.
