The 68-year-old entrepreneur could throw in his hat in 2024 after selling his plumbing business this week in a deal estimated to be worth between £145 million.
“It’s still a few years away, so let’s see how it goes, but I don’t rule out running for mayor of London,” he told Times Enterprise Network.
Mr Mullins, dubbed Britain’s first millionaire plumber, considered running for mayor of London in the 2021 elections, with Sadiq Khan voting for a second term in office.
However, he withdrew after deciding that a political career wouldn’t work, while also representing Pimlico Plumbers, whom he founded in 1979.
The next election will take place after Mr Khan has completed his three-year term.
Speaking from his Spanish villa in Marbella, Mr Mullins spoke of how the sale of the company gives him the opportunity to do other things, including representing London and focusing on the music industry.
He also recently revealed that his son Scott will remain CEO.
“It was a big decision to make, to leave completely. I’ve spent my whole life with Pimlico,” said Mr Mullins the mirror.
“But I passed it on to good people. Neighborly has the same work ethic as I do, and they have the financial backing.”
Mr Mullins was a staunch opponent of the Brexit deal and he had called on Theresa May to step down as Prime Minister as her bill faced a tough ride through the Lords.
The company has been sold to US home services giant Neighborly, according to a statement posted on its Twitter page on Tuesday.
It read: “The legendary company founder, Charlie Mullins, has moved on to embark on his next adventure.
“But the company remains a family affair led by his son, CEO Scott Mullins.
“The acquisition by the world’s largest home service brand franchisor, with 10 million customers, is an international milestone and represents tremendous opportunity for growth, innovation and prosperity for both organizations.”
