New in 2015, the monthly Builders Merchant Building Index (BMBI) report is the only reliable measure of Repair, Maintenance & Improvement (RMI) building activity in the UK. It’s an opportunity for the industry and the Builders Merchant Federation (BMF) to build awareness and understanding of our markets and leading brands. That’s why we created the BMBI. The BMBI is produced by MRA Marketing, under the aegis of the BMF, using sales-out data from GfK’s general builders’ merchant panel. With input from national and regional builders’ merchants accounting for over 80% of industry sales, no other indicator in construction is as comprehensive, up to date or reliable. BMBI reports are published monthly in the Builders’ Merchant News. To download the latest reports, please visit https://www.bmbi.co.uk
