Who Is CMO?

Construction Materials Online (CMO) is a leading online supplier of construction materials in the UK.
An innovator, the company challenges traditional channels in the distribution of building materials,
providing the convenience of online retail with comprehensive product knowledge.


Our specialist online stores

As the launch site for CMO, Roofing Superstore (first to market in its field), is today recognised as the UK’s largest online roofing merchant. This business model has since been replicated for subsequent sister sites, Drainage Superstore, Insulation Superstore and Door Superstore, while CMO continues to identify opportunities for further growth and efficiencies. By combining its successful model with trusted, bespoke, web-based application, a proven track record in the business of construction and over 65,000 building supplies products across specialist construction disciplines, the company satisfies modern consumer demands for a smarter, online solution to purchasing building materials.
