Welcome to CES

Who We Are

CES Sustainable Engineering Building Services

CES are specialists in sustainability, creating low and zero carbon buildings.

CES was formed in 1999 with a clear strategy to create low carbon buildings through environmentally considered designs. We have developed our team to 14-strong technical staff based in Clerkenwell, the design centre of London. We work very closely with our clients, architects and the rest of the construction team, collaboratively to produce sustainable low and zero carbon buildings.

We believe the design process should stimulate the team to excel and are always interested in developing new with traditional ideas to create environmentally sound buildings. Climate Change is the communal challenge of our generation; up to 50% of total UK emissions are produced by buildings. Through the development of sustainable buildings it is possible to eradicate most, if not all building related emissions. We believe each project is an opportunity to statement how buildings should work and can work in the future to mitigate the effects of carbon emission.

Our personnel have more than 30 years’ experience and have completed a number of Award Winning Projects, remaining innovators in sustainability since our company’s inception in 1999.
