Charlie Mullins, founder of Pimlico Plumbers and Britain's richest plumber, is selling his £12 million London penthouse as he prepares to leave the UK due to fears of increased taxes under the new Labour government. He aims to have 'no assets in the UK whatsoever' and is redirecting his investments to countries like Spain and Dubai. Mullins expressed particular concern over potential increases in inheritance tax, stating that losing £6 million from his property due to such taxes would greatly upset his family. With Labour leader Sir Keir Starmer and Chancellor Rachel Reeves hinting at a tax raid on the wealthy, Mullins is among many affluent individuals considering relocation to avoid higher taxes. Despite his plans to exit, he is launching a new plumbing venture called WeFix in London, funded through his children's trust. Experts predict a significant outflow of millionaires from the UK, with estimates suggesting 9,500 will leave in 2024, more than double last year's figures.
