This move has astounded industry pundits. Mullins has always staunchly refused to take Pimlico Plumbers public. Nothing is set in stone as yet, however. Mullins says: "Along with the obvious outcome of providing a lot of valuable investment capital to further grow my operation, it is true there are other considerations related to going public that need to be seriously looked in to. The main one being my ability to retain control of the direction Pimlico Plumbers takes and, most importantly, that means retaining a direct relationship with our customers.
"Over the years the company has grown as a direct result its ability to react to customer demand, and that cannot be allowed to change."
Mullins founded Pimlico Plumbers back in 1979. The £15m-turnover business reported profits of nearly £350,000 last year. Listing on the stock exchange would value Pimlico Plumbers at £50m.
There's no chance of Mullins losing his iron grip on the company operations, however. He intends to retain a majority stake: "Let me be quite clear," he says. "I have no interest in losing control of the company that I have built up with more than 30 years of hard work, and, if shares were to become publically available, I intend to keep hold of a controlling interest."
