BMBI – Builders Merchant Building Index

Launched 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. Filling an important gap, it can be widely used in construction, and by economists, Government, national media commentators and influencers outside the industry.

The monthly series tracks what is happening in the market month by month and includes an in-depth review every quarter. This trend series gives our industry access to far more accurate and comprehensive data than that available to other construction sectors.

The reports also include views from a panel of leading industry experts to help explain trends, issues and opportunities in their markets. It’s an opportunity for the industry to build awareness and understanding of our markets and leading brands.

IKO is proud to be part of BMBI, with Managing Director Andy Williamson as the leading industry expert for roofing.
