Marley sustainability

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, be awarded Certified Environmental Profiles by BRE (Building Research Establishment), and 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 operates quality, health and safety and environmental management systems including ISO 9001, ISO 14001, and ISO 45001.

Declaration of Performance (DoP)

Marley takes product performance and quality very seriously, and regularly test our products to ensure they are compliant and UKCA and CE marked. Below you will find our Declaration of Performance (DoP) for each of our manufactured products. For our customers' ease, we have grouped product lines into one DoP making it easier to find and manage.

Customers receive the UKCA and CE marks via the packaging on our products and/or the delivery notes that travel with the product, to comply with the Construction Product Regulation standard.
