The collapse has resulted in the loss of 1,000 jobs, in addition to the closure of 22 out of 25 of the celebrity chef's UK restaurants.
On Tuesday, administrators at KPMG released a list of the branches which are due to close effective immediately.
While three of Oliver's restaurants are staying open, the branches could still be at risk of closure in the near future if a buyer doesn't purchase the company.
The three remaining restaurants are all based at Gatwick airport.
International restaurants trading as Jamie’s Italian, Jamie’s Pizzeria and Jamie’s Deli will continue business as usual.
Here's the full list of all the Jamie's Italian restaurants which have closed:
- London (Islington)
- London (Covent Garden)
- London (London Bridge)
- London (Piccadilly)
- London (Victoria)
- London (Westfield White City)
- London (Westfield Stratford)
- Other closures
- Barbecoa (One New Change shopping centre, London)
- Fifteen (Hoxton, London)
Here are the three restaurants remaining open:
- Jamie's Italian (Gatwick North, London)
- Jamie's Italian Coffee Lounge (Gatwick North, London)
- Jamie Oliver's Diner (Gatwick South, London)
Oliver said he was "devastated" following the news of his company's collapse.
"I am deeply saddened by this outcome and would like to thank all of the people who have put their hearts and souls into this business over the years," the chef tweeted.
Last year, Oliver revealed that two years ago he put £13m into his restaurant business, as it had been nearing bankruptcy.
In January 2018, he closed 12 of his restaurants and let 600 members of staff go from the business.
Josh Singh, 24, who began working for Oliver's company in 2013, said he was "gutted" upon being informed that he had lost his job.
"We received an email from KPMG basically saying, 'I'm afraid you're sacked, don't bother coming into work'," Sing said.
Chef Colin Roberts, 31, who has worked at Jamie's Italian in Birmingham for 19 months, said "speculation was rife" that something was going on prior to the announcement.
