This move follows an investigation by two of the UK’s largest suppliers of sheet metal to roofers – Associated Lead Mills Ltd (ALM) and HJ Enthoven Ltd (trading as BLM British Lead).
The companies admitted to forming an illegal cartel last year and were fined more than £ 9 million.
The CMA has now secured the disqualification of Jocelyn Campbell (BLM) as well as Graham Hudson and Maurice Sherling (ALM). All of them were directors at the time of the illegal activities.
Campbell also tried to hide his communications with competitor companies by using a different cell phone as his main phone from December 2016 until the investigation began in July 2017. This only became known when the CMA seized the phone.
Sherling admitted to suspecting that ALM is violating competition law and receiving competitive information from a competitor (Campbell of BLM) but does nothing to prevent it.
Campbell is disqualified for 6.5 years, Hudson for four years, and Sherling for three years.
Michael Grenfell, Executive Director of Enforcement at CMA said: “It is an important responsibility of business leaders to ensure that their companies are not engaging in illegal anti-competitive practices that can result in higher prices for customers.
“The CMA has clear evidence that these directors either knowingly made illegal agreements and communications or were aware of them and did nothing to stop them.
“That is why these measures are necessary. This should be a message to all directors. If your company violates competition law, you risk personal disqualification. “
