Heston Blumenthal has no reliable published net worth. The most-quoted online figure, $5 million (about £3.7 million), comes from Celebrity Net Worth and is not sourced. What can be checked is more surprising: Blumenthal sold the Fat Duck business years ago, and the group that owns it lost £1.7 million in its latest accounts before a new investor stepped in.
He is back on screens this month in the BBC Two series Rise of the Rockstar Chef, alongside Gordon Ramsay and Marco Pierre White. So it's a good moment to separate the chef's fame from the money. This piece sticks to Companies House filings and dated press reports.

He doesn't own the Fat Duck
In March 2008, This is Money reported that Blumenthal had quietly sold the Fat Duck to Ronnie Lowenthal, the stepbrother of his father, while staying on to run the kitchen. A New Statesman profile in August 2026 dates the sale earlier, to 2004, and says the arrangement was meant to keep him away from the financial side and free to focus on ideas.
Companies House fits that picture. Blumenthal resigned as a director of The Fat Duck Limited, The Hinds Head Limited and several related companies on 15 November 2006. Today both restaurant companies are 100% owned by SL 6 Limited. That holding company's most recent accounts name Cape Proprietary Inc, incorporated in Nevis, as the immediate parent, and Lowenthal Corporation Limited, incorporated in the Isle of Man, as the ultimate parent. Neither the accounts nor the SL6 register list Blumenthal as an owner or a person with significant control.
In 2018 a spokeswoman told the Sydney Morning Herald that Blumenthal had sold his shareholding "more than a decade ago" but remained chef patron and "integral" to the business.
That doesn't make him poor. It does mean the value of the Fat Duck business and brand does not sit on his personal balance sheet, at least not in any filing the public can see.
What the SL6 accounts show
SL6's group accounts for the period to 25 May 2025 were filed on 4 August 2026. They cover the Fat Duck and the Hinds Head pub in Bray, plus smaller brand and licensing companies.
- Turnover: £9.15m, up from £8.94m. Of that, £8.90m came from the restaurant and pub, and £242,053 from royalties.
- Gross margin: 76%, but administrative costs of £8.3m wiped it out.
- Result: a post-tax loss of £1.7m, after £2.1m the year before.
- Balance sheet: net liabilities of £4.37m, with £203,932 cash at bank.
- Directors' pay: £51,000 in total for the period.
The auditor flagged a material uncertainty related to going concern. Ongoing losses and a negative balance sheet could, it said, cast significant doubt on the group's ability to keep trading, though its opinion was not modified. The directors tied the going-concern case to new funding agreed after the year end.
Things looked better in 2023, when Restaurant Online reported that SL6 had made a £2m profit in the year to May 2022, as sales more than doubled to £11.5m.
The COMO deal and the end of Dinner
That new funding came from COMO Group, the Singapore-headquartered hospitality company founded by Christina Ong. According to the accounts, SL6 signed a convertible loan agreement with Como Holdings (UK) Ltd, the COMO-linked company named in the filings, on 26 March 2026. Cape Proprietary also converted £2.9m of debt it was owed into shares. Companies House has recorded Como Holdings (UK) as having "significant influence or control" over SL6 since the same date. The deal was announced publicly in May 2026. The amount was not disclosed, and the group says it wants to explore expansion.
Meanwhile Dinner by Heston Blumenthal, at the Mandarin Oriental Hyde Park since 2011, is due to close in January 2027. Blumenthal told the Times, as quoted by Time Out: "We are effectively tenants in a building and our tenancy is finished."
Where his own money has come from
With no published estimate to lean on, the next best thing is to look at where his money has actually come from:
- Television. Channel 4 series such as Heston's Feasts made him a household name, and the Telegraph reported in October 2026 that he used his media earnings to subsidise the Fat Duck.
- Waitrose. His product range, which began in 2010 and produced the famous hidden-orange Christmas pudding, ended in early 2023 after a 12-year partnership, according to the New Statesman.
- The sale itself. What Lowenthal paid for the Fat Duck has never been made public.
- His chef-patron role. He is the face of the restaurants. The accounts don't say what, if anything, he is paid personally.
He now lives in France with his wife, Melanie, and the couple manage the Fat Duck from there, the New Statesman reports.
So what is Heston Blumenthal worth?
From public records, nobody can say with any confidence. The $5m online figure might be in the right range or nowhere near it, and nothing public backs it up. What the filings do show is that the empire with his name on it is owned by others, has been losing money, and now relies on COMO's backing. For contrast, read our Gordon Ramsay accounts breakdown.
