Reporting to chief executive Kate Tinsley, chief operating officer Dave Castle brings more than 20 years of experience in the building materials sector, most recently as chief commercial officer and managing director of Travis Perkins’ pipe and heating subsidiary BSS.
MKM Building Supplies has grown fourfold over the past 10 years, from £250m revenues in 2015 to nearly a billion last year. It had 47 branches when it was taken over by Bain Capital in 2017; it now has 132, with 11 new openings in 2024.
Commenting on his new role, Dave Castle said: “I’m thrilled to be joining MKM at such a pivotal time. What makes this business different is the unique mix of local, independent feel and national scale. It’s a merchant that genuinely puts tradespeople first – and that’s why it’s winning.
“I’m looking forward to supporting our branch teams to keep doing what they do best: offering great service, fair pricing, and expert advice. Looking ahead, we’ll keep expanding into new areas, embracing smarter ways of working, and helping customers stay ahead of changes in the market – whether that’s environmental regulation or new product requirements.”
Chief executive Kate Tinsley added: “Dave’s a fantastic addition to the team. His commercial experience, deep sector knowledge and leadership style are a great fit for MKM. As we scale up, his appointment reflects our focus on growing with purpose – investing in people, supporting branches, and staying true to our values.”
