Heston Blumenthal: Bipolar Diagnosis, Restaurant Closures, 2025

Heston Blumenthal, the molecular gastronomy pioneer who turned bacon-and-egg ice cream into a national talking point, has spent three decades redefining British food. But in 2025, the headlines focus less on liquid nitrogen and more on his bipolar diagnosis, the restaurant closures that shook London’s dining scene, and where he stands now.

Born: 1966 ·
Michelin stars: 6 (3 at The Fat Duck, 2 at Dinner by Heston, 1 at The Hind’s Head) ·
Diagnosis: Bipolar disorder ·
TV shows: Heston’s Feasts, Heston’s Mission Impossible ·
Number of restaurants: 3 (The Fat Duck, Dinner by Heston, The Hind’s Head)

Six facts from across his career and personal life, one pattern: the same relentless drive that earned him six Michelin stars also fueled a private battle that he only recently began to speak about publicly.

What has happened to Heston Blumenthal?

Overview of recent events

• On 16 March 2025, The Guardian published a major profile of Blumenthal exploring his bipolar diagnosis and its impact on his life and career.
• A month earlier, in February 2025, BBC News released a video feature where Blumenthal stated: “If I could turn off my bipolar, I wouldn’t.”
• In June 2025, RTÉ reported that Blumenthal had been sectioned under the Mental Health Act, describing the experience as “like a nightmare”.

Financial challenges

Blumenthal’s restaurant empire has faced significant financial pressure. Dinner by Heston at the Mandarin Oriental in London closed in 2023, and a March 2026 report from The Guardian stated the restaurant’s tenancy was set to end permanently in January 2027. High operating costs and lease issues were cited as contributing factors.

Health updates

Blumenthal has become increasingly open about his bipolar disorder since first revealing his diagnosis in 2016. In a BBC article from June 2025, he described how the diagnosis fundamentally changed his life. He now serves as an official ambassador for Bipolar UK, and has shared techniques such as keeping a symptom diary and using NHS-backed screening tools in interviews posted on YouTube.

The 2025 Guardian profile captures this duality: the same man who created culinary marvels also faced a mental health crisis and emerged with a new purpose.

Why is Heston Blumenthal closing his Michelin star restaurant?

Reasons for closure

• Dinner by Heston at the Mandarin Oriental in London closed in 2023.
• A March 2026 investigation by The Guardian into Blumenthal’s “sinking empire” highlighted the end of the tenancy lease as the primary driver.
• The World’s 50 Best confirmed in early 2026 that Dinner by Heston would close permanently in January 2027.

Impact on staff and customers

Details about staff redundancies have not been made public, but the closure of a 120-cover restaurant in Knightsbridge with two Michelin stars inevitably displaced dozens of workers. For regulars, the loss of Dinner by Heston — which had operated since 2011 — meant the end of a flagship venue that reinterpreted historic British dishes like “Meat Fruit” and “Tipsy Cake”.

Future plans

Blumenthal continues to run The Fat Duck in Bray, which celebrated its 30th anniversary in August 2025 according to The Guardian. A RestaurantOnline piece from September 2025 reported that Blumenthal was again a regular presence at the restaurant, crossing the Channel at least once a week.

The implication: closing Dinner by Heston was less about abandoning London and more about concentrating resources on the flagship site that made his name. His brand is consolidating, not shrinking.

What has Heston Blumenthal been diagnosed with?

Diagnosis details

• Blumenthal was diagnosed with bipolar disorder, a mental health condition characterised by extreme mood swings between mania and depression.
• He first revealed the diagnosis publicly in 2016 in an interview with The Guardian.
• In June 2025, RTÉ reported he had been sectioned under the Mental Health Act, a legal process used when a person with a mental disorder needs assessment or treatment for their own safety.

Impact on his career

Blumenthal has said the diagnosis allowed him to understand patterns in his behaviour that had previously seemed inexplicable. In multiple interviews — including a BBC News video from February 2025 — he reframed his bipolar disorder as intrinsic to his creativity, stating he would not choose to eliminate it.

Management and treatment

Blumenthal has described using practical tools to manage his condition, including keeping a symptom diary and using screening tools developed by the NHS and Bipolar UK, as he shared in a YouTube interview in March 2025. He has also spoken about his ADHD alongside his bipolar diagnosis in a podcast posted on YouTube in February 2025.

Has Heston Blumenthal won any Michelin stars?

List of Michelin stars

• Blumenthal has won a total of 6 Michelin stars across three restaurants.
• The Fat Duck in Bray holds three Michelin stars, awarded in 2004.
• Dinner by Heston in London held two Michelin stars from 2011 until its closure.
• The Hind’s Head in Bray holds one Michelin star.

The Fat Duck’s three stars

The Fat Duck received its first Michelin star in 1999, its second in 2001, and its third — the highest rating — in 2004, according to The World’s 50 Best. It remains one of only a handful of UK restaurants with three stars.

Other restaurants

Dinner by Heston opened in 2011 at the Mandarin Oriental in Knightsbridge, London. It earned two Michelin stars before closing in 2023. The Hind’s Head, a gastropub also in Bray, holds one star. Blumenthal’s total of six stars places him among the most decorated chefs in the UK, alongside Gordon Ramsay and Alain Ducasse.

The implication: concentrating resources on the flagship site that made his name.

How is Heston Blumenthal now?

Current health status

• Blumenthal continues to manage his bipolar disorder and has described himself as stable and functional.
• He serves as an official ambassador for Bipolar UK as of September 2025.
• He remains a regular presence at The Fat Duck, according to RestaurantOnline.

Recent projects

In addition to running The Fat Duck, Blumenthal has been involved in television and writing. His role as a Bipolar UK ambassador has led to public speaking engagements and media appearances, including the BBC News feature in February 2025. He also participated in a podcast with Bipolar UK in March 2025 focusing on stigma reduction.

Public appearances

Blumenthal has been more visible in 2025 than in the previous few years. The Guardian profile from March 2025, based on an interview at The Hind’s Head, paints a picture of a man who has emerged from a difficult period. He is cooking, managing his health, and speaking publicly about both.

What this means: after a period that included financial strain, a restaurant closure, and a hospitalisation under the Mental Health Act, Blumenthal has not only returned to his kitchen but has also taken on a public advocacy role. The shape of his career has changed — smaller, more focused, more intentional — but he is still very much in the game.

For Heston Blumenthal, the choice between protecting his privacy and using his platform to destigmatise mental illness is one he has clearly decided in favour of the latter. For the wider hospitality industry, the implication is just as stark: the same personality traits that produce three-Michelin-star creativity can also produce severe mental health crises. For restaurant owners and chefs watching from the sidelines, the signal is clear — speak up early, or risk a very public breakdown.

Frequently asked questions

For the British restaurant industry, the lesson from Blumenthal’s last three years is uncomfortable but unavoidable: the pressure to maintain Michelin stars, manage a brand, and keep up with media expectations can break even the most celebrated chef. For Blumenthal himself, the next chapter is about focus — one restaurant, one cause, one kitchen. For the diner who once queued for hours to try snail porridge, the hope is that the man who made British food weird and wonderful again is around long enough to do it one more time.
