Earlier this year, the businessman came in at number three in The Sunday Times 2026 Tax List, which ranks the individuals and families who paid the most tax over the last year.

The paper reported that he paid £330 million in tax across that period, while being paid nearly £500 million.

As previously reported by this paper, accounts filed with Companies House show that Mr Rokos scooped £476,795,990 during a profitable year for his firm Rokos Capital Management.

For several years, Mr Rokos has been carrying out a major refurbishment of the Tottenham House mansion and this significant project remains ongoing at the time of writing.

He hopes to move in with his family from next summer onwards after purchasing the property eight years ago.

The Sunday Times was recently given access to the works and reported that the total bill is expected to reach £175 million, making it the "UK’s most expensive home renovation".

When combined with the £11.3 million purchase price and later acquisitions of buildings and land, the total investment could be more than £200 million.

The planned changes involve the modernisation of the historic property for 21st century living as well as the introduction of a 40-acre solar farm and drainage lagoon.

Mr Rokos was beaten to the title of richest individual with links to Wiltshire by Sir James Dyson, despite the manufacturer seeing a huge drop in his wealth.

Sir James’ worth plummeted from £20 billion to £12 billion, according to The Sunday Times, but this was still enough for 13 th place on the list.

The rankings were topped by Sanjay and Dheeraj Hinduja and family, whose worth was recorded at £38 billion.
