Prince William's fortune surpasses £1bn as he sits wealthier than King Charles

Prince William has been confirmed as a billionaire, with newly released financial documents revealing his wealth now exceeds that of his father, King Charles.

The heir to the throne possesses net assets totalling £1.2billion through the Duchy of Cornwall, according to figures published yesterday.

This substantial fortune, comprised predominantly of investment property holdings, places the 44-year-old Prince of Wales considerably ahead of his father, King Charles, in terms of personal wealth.

The King, by contrast, appeared at 238th position in the most recent Sunday Times Rich List with an estimated personal fortune of £640million, representing an increase of £30million from the previous year.

As the Duke of Cornwall, William is entitled to annual profits from the Duchy's landed estate, which encompasses 51,800 hectares spanning 19 counties.

The Prince of Wales received a private income of £21.6million during the 2025-26 financial year from the Duchy.

And he has contributed more than £20million in taxation to HMRC since assuming his current title.

His tax payments amounted to £7.76million in income and capital gains tax for 2024-25, following £8.34million the previous year.

The 2024-25 contribution represented an effective rate of 34 per cent on the £22.9million private income he drew that year, compared with the King's 45 per cent rate.

Royal aides indicated the decision to publicly disclose his taxes was the Prince's own, made in the interests of greater transparency.

This disclosure coincided with King Charles also releasing his tax information for the first time as sovereign.

The Prince has moved to address controversy surrounding the Dartmoor Prison rental arrangement.

William has requested that the £1.5million annual rent from the abandoned Devon facility be removed from his personal income from 2026-27 onwards.

Instead, these funds will be channelled into regenerating the local community of Princetown.

A Dispatches and Sunday Times investigation in 2024 revealed the Duchy had agreed a £37million deal in 2022 to lease the category C prison to the Ministry of Justice for 25 years at £1.5million annually.

The facility has stood empty since July 2024 after dangerous levels of radon, a naturally occurring toxic gas linked to lung cancer, were detected in prisoner accommodation.

A community-led regeneration fund is scheduled to launch next year, offering social, economic and environmental benefits to the isolated rural settlement.

The Prince's private secretary Ian Patrick explained the reasoning behind the Dartmoor decision: "Prince William knows that for many people in Princetown, the prison has long been part of the fabric of the community."

Mr Patrick added: "Its closure has created genuine uncertainty, not just about jobs and businesses, but about the future of the town itself."

He continued: "The duke felt strongly that, while those questions remain unanswered, the benefit of this income should remain in the community, helping local people shape that future."

Regarding the financial disclosures, Mr Patrick stated: "The Prince recognises the interest in these arrangements and the importance of appropriate transparency."

Kensington Palace also confirmed that household staff numbers have grown from 68 to 74.
