The eight richest Channel Islands residents hold more than £15.9 billion between them, according to the Sunday Times Rich List – but the combined wealth of those featured in the publication is falling.

Jersey-based whiskey tycoon Glenn Gordon is the top Channel Islands resident on the list at number 29 – up from 36 last year.

Mr Gordon and his family is worth £6.4bn, according to this year’s Rich List.

The paper estimates that the owners of leading Scottish distiller William Grant and Sons have seen their fortune rise by £779m over the past 12 months.

The next Channel Islands residents are The Range owners Chris and Sarah Dawson, who have a total worth of £2.6bn.

The Jersey-based couple increased their wealth by £100 million in the last year, moving from 70th to 64th on the list.

They are followed by tech entrepreneur Simon Nixon, founder of MoneySupermarket, who is 86th on the list with a £1.95bn fortune.

He got £70 million richer last year, and moved up from 90th spot on the Rich List.

Guernsey’s wealthiest couple is still Specsavers’ Douglas and Dame Mary Perkins, who took the 107th spot on the list – although their wealth fell by almost £50 million to £1.5bn.

Guernsey fund manager Steve Lansdown completes the Channel Islands top five at 127th. His current wealth is £1.25bn, having risen by £82m last year. He was 150th previously.

Jersey-based hedge fund manager Paul Sykes is 205th on the list with wealth of £775m. Although his net worth has not changed since last year, he has moved up 11 places on the list from 216th.

Former Trinity Seigneur Steve Morgan is 158th on the list – moving up from 180th last year.

His wealth, acquired from his construction firm Redrow, is worth £988m – having increased by £73m in the last 12 months.

Meanwhile, the Clarke Family – which owns Le Masurier Property – moved up from 284th 271st on the list. They were worth £510m this year.

Sunday Times Rich List compiler Robert Watts said: “The Sunday Times Rich List is changing.

“Our billionaire count is down and the combined wealth of those who feature in our research is falling. We are also finding fewer of the world’s super rich are coming to live in the UK.

“This year we were also struck by the strength of criticism for Rachel Reeves’s Treasury. We expected the abolition of non-dom status would anger affluent people from overseas.

“But homegrown young tech entrepreneurs and those running centuries-old family firms are also warning of serious consequences to a range of tax changes unveiled in last October’s budget.”

He added: “Our research continues to find a wide variety of self-made entrepreneurs building fortunes not just from artificial intelligence, video games and new technologies but also mundane, everyday items such as makeup, radiators and jogging bottoms.

“We know many of our readers find these people and their stories inspiring – especially the many who had tough starts or setbacks to their lives and careers.”
