Material Index (MI) is a team of contractors, architects, engineers and software developers focussed on enabling reuse at scale in the construction industry.
We provide tools to the industry to help contractors, consultants and building owners reuse more materials. You can use our AI Audit app for creating detailed audits with advanced reporting features. You can also buy and sell materials on our marketplace.
We also offer pre-demolition audits, material passports, and material brokerage as services direct for clients, conducted by our expert in-house team.

We hosted our Circular Economy networking drinks at The Crown Tavern, Clerkenwell — a sunny evening of brilliant energy where we showcased our reclaimed marketplace, new AI features, and latest platform capabilities to a room full of passionate people from across the circular economy.
The Material Index team returned to British Land's 1 Appold Street for the Contracts for Innovation Demonstration Day, joined by DESNZ and UK Research and Innovation.
