Standards and Certificates

Management certification 

We have been at the forefront of environmentally responsible manufacturing and working processes from the early 1990s and ever since, we have taken practical steps that help us and others in the industry to be as environmentally responsible as possible. 

We were the first in the roofing industry to have our LCA (Life Cycle Assessment) data verified and to be awarded Certified Environmental Profiles by BRE (Building Research Establishment); and to be awarded ISO 14001 - the internationally recognised standard for environmental management systems - at all of our factories. 

Manufacturing processes are constantly reviewed to minimise their environmental impact and each year, we actively look for ways to improve our procedures and reduce our environmental impact even further.  Marley operate Quality, Health and Safety and Environmental management systems including; ISO 9001, ISO 14001 and BS OHSAS 18001.
