Supply chain

A resilient, responsible supply chain


We validate all supplier claims and third-party certifications such as ISO, BRC and FSC. And we ensure suppliers adhere to UK and EU laws on chemicals and product components, like UK REACH. This allows businesses to confidently buy high-quality products that align with a net-zero trajectory.

Look for our FSC® certified products.

Vetted suppliers

We vet every supplier we work with. We do this through site visits and rigorous product testing.

Quality control

Every lot from our suppliers undergoes a quality inspection process before it’s shipped. Any lot that fails quality inspection is returned to the manufacturer or reproduced.

For orders manufactured internationally (outside the UK), we follow the Acceptable Quality Limit (AQL) method defined by ISO 2859 - 1.

For orders manufactured domestically (inside the UK), our suppliers perform the quality inspection process which we then verify through spot checks throughout the year.
