The Builders Merchants Federation (BMF) has appointed Dave Castle, Chief Operating Officer at MKM Building Supplies, as a Board Advisor, with effect from 27 May 2026.

Castle has over 25 years of experience in the building materials sector. He became MKM’s first COO twelve months ago. Prior to this, he was Group Chief Commercial Officer and MD of BSS at Travis Perkins Group, where he began his career as an apprentice in 2001.

In addition to its board of directors, the BMF may appoint up to two non-voting advisors to strengthen the advice available to it on merchant, supplier or regional issues.

Castle originally served as a BMF Board Director in 2024/25 but resigned upon leaving Travis Perkins. As a Board Advisor, he replaces Martin Stables of IBMG, who stepped down in March 2026. Like Stables, Castle has experience with a regional merchant group investing in an ambitious growth journey while achieving a unique blend of a local, independent feel and national scale.

Richard Hill, BMF Chairman, said: “We are delighted to welcome Dave back as a Board Advisor.  He brings commercial expertise and deep sector knowledge gained from his experience across the merchant sector, which will be invaluable to the BMF as we continue to drive innovation and growth in support of our members.”
