What 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 and Insulation 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 50,000 building supplies products across specialist construction disciplines, the company satisfies modern consumer demands for a smarter, online solution to purchasing building materials.

Our Products

CMO supports British manufacturing and innovation, as well as providing leading global brands to an engaged customer base. With over 50,000 products listed in the specialist construction fields of roofing, drainage, insulation and energy efficiency, CMO offers a fair deal, at best price, with the principal aim to add value across the construction industry, from manufacturer to end consumer.
