The team from Knauf Insulation UK & Ireland take the title for the second successive year.
The ongoing heatwave did not deter teams from across the building materials sector giving thier all on at the Builders Merchants Federation MasterMerchant 2025.
Overlooking the stunning Lake Windermere, in the Lake District, each team spent a few unforgettable days of challenge, collaboration, and connection. From team trials to networking under the sun, this year’s event truly brought out the best in everyone.
A special congratulations to Knauf Insulation UK & Ireland ‘Thermal Titans’ for securing the win for the second year running – and making history as the first supplier team to earn a place on the legendary Mastermerchant shield. Take a bow Jo Callow, Luke Davies, Gerard McGuigan and Terry Callow.
Stacey Lock, Events Manager at the BMF, said: "A huge well done to all who took part – it was inspiring to see teams push themselves, build stronger bonds with colleagues, and form new relationships across the sector.
"This was my third time running the event, and each year I’m reminded why this tradition matters so much. Here’s to an even stronger showing in 2026, as we build toward the 40th anniversary of BMF MasterMerchant in 2027."
