Jon Boast, the cameraman husband of A Place in the Sun presenter Jasmine Harman, suffered a mild heart attack during filming in Spain in May 2025. The incident was captured on camera and broadcast on Channel 4 in November that year. He has since recovered and returned to work.
The cameras were still rolling when Jon Boast told viewers what his doctors had just confirmed. From a hospital bed in Estepona, Spain, he looked into the lens and said it plainly: “The blood test results suggest that I’ve had a mild heart attack.”
His wife, Jasmine Harman, had called the ambulance earlier that same afternoon. She was four days away from her 50th birthday.

What Happened to Jasmine Harman’s Husband
Jon had been talking with one of the builders at the couple’s half-finished home when his chest tightened and his arms began to ache. He went inside to lie down. The symptoms did not pass.
Jasmine recalled the moment in her exclusive interview with The Mirror:
“We’d just had lunch and he said he started to feel funny and strange. He went to lie down but he then started to get very agitated and said there was a tightening in his chest. He was having a bit of trouble breathing and everything that was touching him was annoying him. I immediately called the ambulance as soon as he said he felt funny.”
Speaking from his hospital bed in the episode that aired on 11 November 2025, Jon described it himself:
“Mid-renovation, this afternoon, when we were with one of the builders, I got sort of pains in my chest and tight chested, achy arms. We called an ambulance, and now I’m in hospital. The blood test results suggest that I’ve had a mild heart attack.”
He added, with typical understatement: “I think sometimes it’s called an angina, which sounds way less scary than a heart attack, but anyway, they’re doing tests.”
Jon Boast’s Full Health Timeline in 2025
The heart attack was the second serious health crisis Jon faced that year. His 2025 had already gone badly wrong months earlier.
| Month | What Happened |
|---|---|
| January 2025 | Fractured his left leg in a padel tennis accident |
| Jan onwards | Developed thrombosis during recovery |
| May 2025 | Suffered a mild heart attack during filming in Estepona |
When Jon collapsed in May, Jasmine was already aware of the blood clot he had developed from the leg fracture. She called the ambulance immediately and, by her own account, stayed composed.
“As he had thrombosis from the leg break, it was obviously scary but I don’t know why, something inside me was saying: ‘don’t panic, it’s going to be fine’. I was very calm.”
The interior design company My Bespoke Room, which worked on Renovation in the Sun, later confirmed that Jon had been unwell twice during the filming period, and that the full weight of the project had landed on Jasmine throughout.
Jon Boast’s Family History of Heart Conditions
This health scare was heavier than most because Jon’s family already knew what sudden cardiac events could take.
His sister, Jo Boast, died suddenly in 2016, aged just 40, from sudden arrhythmic death syndrome. Jasmine described the loss: “She was fit, well and very healthy. It was a very big shock.”
That death had already pushed Jon to take his cardiac health seriously long before 2025. He had been attending regular screenings specifically because of his family history — something that proved critical after the heart attack.
What Is Sudden Arrhythmic Death Syndrome?
According to the British Heart Foundation, SADS is when someone dies suddenly from cardiac arrest with no identifiable cause, because the heart appears structurally normal at post-mortem. The cause is an electrical fault in the heart’s rhythm — not a blocked artery, which is what distinguishes SADS from a standard heart attack. These are two separate cardiac events.
Key figures from published medical research:
- SADS affects around 500 people in the UK every year (British Heart Foundation)
- 18% of SADS cases involve a family history of premature sudden deaths
- When first-degree relatives of SADS victims are screened, more than 20% carry some form of inherited heart rhythm condition (PubMed / National Institutes of Health)
After confirming Jon’s mild heart attack, the Spanish hospital acted on his family history straight away. Jasmine told The Mirror:
“With Jon’s family history, he’d already been having regular screenings. Now they are doing more investigations and keeping an eye on him. He’s on medication and they will continue to do regular monitoring.”
Did Jon Boast Recover From His Heart Attack?
Yes. By late 2025, Jon was back in work and the family’s home in Estepona was finished.
Jasmine gave her full account to The Mirror in her first interview about the ordeal, published around the time the episode aired:
“Jon is fine now and he is back working. I know this sounds strange but even with the background of what could have happened and worrying he could have died; it makes you feel lucky he just had a mild heart attack and everything is fine.”
During the most difficult stretch of filming and recovery, Jasmine’s mother Vasoulla flew out from the UK to Spain to help.
“With Jon also breaking his leg, now when I look back on everything, I don’t know how I did it. What I do know is I wouldn’t have been able to do it without my mum. When she arrived, I let go of all the pressure and the stress.”
Who Is Jon Boast?
Jon Boast, born in August 1979, is a British television cameraman and cinematographer. He has worked across lifestyle and property television throughout his career, with credits including Kirstie’s Vintage Home, Kirstie’s Celebrity Craft Masters and Kirstie’s Handmade Britain. He also worked alongside Hairy Bikers presenter Dave Myers for a number of years. Dave died in February 2024, and his widow Lili visited the Estepona renovation during filming of the show.
Jon met Jasmine on the set of A Place in the Sun, where he worked as a cameraman while she presented. Jasmine has described the early stages of their relationship as “a slow burn — we met, became great friends and then we fell in love.”
They married in June 2009 at Great Fosters, a Grade I listed country house in Egham, Surrey. They have two children: daughter Joy, born in October 2013, and son Albion, born in 2015. Both were conceived through IVF after the couple struggled for years to have children.
In 2017, just months after Jo died, Jasmine and Jon tried for a third child. The embryo failed to implant. Jasmine said: “We’d hoped that welcoming a new baby might have lifted the family and brought fresh joy after such a painful time, but instead we were reminded how fragile and precious life can be.”
Jon described their finished Spanish home to Hello! magazine in a line that says something about who he is: “Stepping through this door is like a sigh of relief. This is not just a house; it’s our sanctuary.”
The Weight Behind It All
Jasmine Harman has been presenting A Place in the Sun on Channel 4 since 2004 — more than 200 episodes, longer than any other presenter on the show. She and Jon relocated from South London to Estepona in 2023 to take on the renovation that became Renovation in the Sun. The series premiered on 3 November 2025.
What the show could not fully convey was how much the couple had already absorbed before a single camera was set up. Jo’s death in 2016. A failed pregnancy in 2017. The loss of Jonnie Irwin, Jasmine’s close friend and co-presenter for 15 years, to lung cancer in February 2024 at 50. And then Jon’s leg, his thrombosis, and his heart attack, all within five months of the same year.
Jasmine told The Mirror:
“The challenges life throws at you has made me take things in my stride a lot better than I used to. I used to be quite a control freak but now I feel I am able to go much more with the flow and not let things get under my skin.”
Jon Boast is back at work. The house in Estepona is complete. And for a couple who have buried a sister, grieved a friend, lost a pregnancy, and watched a heart attack play out on national television, that is not a small thing.
Jon Boast has recovered following his mild heart attack in May 2025. Renovation in the Sun aired on Channel 4 in November 2025. For information on sudden arrhythmic death syndrome or family cardiac screening, visit the British Heart Foundation at bhf.org.uk.
