BS EN ISO 9001-2015

Having our quality management system independently certified through a UKAS accredited body to standard BS EN ISO 9001, we believe demonstrates our commitment to quality, best practice and continual improvement of our procedures. BS EN ISO 9001 proves to stakeholders and customers that quality systems are meeting international best practice. It provides assurance that our quality management system is operating efficiently and effectively, demonstrating continuous improvement and efficiencies year after year.

Product certification is the ultimate endorsement of a product's performance. Products will always be made to achieve a particular performance, whether it's to a British, European or International test standard or simply to the manufacturer's own in-house specification.

Specifiers want greater confidence in a product than a manufacturer's declaration. They want evidence from a reliable independent source to confirm that the product has been properly tested and is manufactured to a consistent high standard.

Exova BM TRADA Q-Mark is regarded as one of the most rigorous certification processes available for construction products, it is recognised by controlling authorities, home warranty providers such as the NHBC (National House Building Council) and is used by world-class construction companies and manufacturers.


Sustainability and exploitation are closely monitored. We have carefully selected the FSC scheme audited by Exova BM Trada to provide us with the essential elements in assuring that the timber product we consume and provide to our customers are both from sustainable sources and do not exploit people in the process of getting product to us. 

We have a passionate commitment to sustainable timber procurement. We are third party audited and accredited. We have 100% FSC procured timber products and you are not charged a premium for this. Through the FSC family we ensure that the supply chain is both ethical in its use of timber and avoids labour exploitation in anyway.

FSC is the world's fastest growing forest certification scheme, driven by increasing market demand for responsible products. More and more businesses and consumers prefer products from well managed forests. FSC provides, the much needed connection between the forest and the end user, ensuring that products with the FSC label uphold the highest social and environmental benefits.

Environmentally appropriate forest management ensures that the harvest of timber and non-timber products maintains the forest's biodiversity, productivity, and ecological processes.
