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.
