A global company of specialist building services and ICT engineers, RED uses its market-leading technical expertise to enable the world's digital infrastructure and helps clients realise ambitious plans for zero carbon-built environments.

RED has led towards the zero-carbon goal for over a decade, thanks to an insistence, from the start, on providing step-change low carbon solutions which are also commercially viable. Today, RED has reached a point on the path towards zero carbon, far beyond that envisaged when it was founded in 2004 – but the urgency of the final goal has become much greater.

A company of ENGIE Impact, RED provides technical expertise to deliver market-leading building services and ICT infrastructure engineering solutions. Our mission is to help global clients accelerate their sustainable transformation with outcomes such as zero carbon leading to a genuinely sustainable future.
