ISO 9001 & ISO 14001 – Marks of Quality and Responsibility
At Chilfen Joinery, delivering exceptional results for our clients has always been at the heart of what we do. Our certification to ISO 9001:2015 (Quality Management) and ISO 14001:2015 (Environmental Management) is an independent endorsement of the standards we apply every day – from first enquiry through to the final installation.
These internationally recognised certifications demonstrate that our processes are robust and efficient, and consistently deliver projects that meet the highest quality standards while minimising environmental impact.
For our clients, this means:
- Confidence that every project is delivered “Right First Time” with precise design and flawless finishes.
- Assurance that we work to a proven framework for quality control, communication, and problem-solving.
- Commitment to sustainable practices that reduce waste and protect resources without compromising results.
When you choose Chilfen Joinery, you’re partnering with a team whose expertise is backed by a rigorous, independently verified approach to quality and environmental responsibility.

Dedication to Sustainability
Being environmentally aware and responsible is something we genuinely take seriously at Chilfen Joinery.
- We have for many years produced energy from our waste products, allowing us to heat our entire facility using materials that would have usually gone to landfill.
- Our paint processes are migrating from high VOC content to water based paints.
- Our ECOGATE controlled ventilation system offers ‘extraction on demand’ and operates only when a particular dust creating machine is in operation reducing energy usage.
- All our products are 100% British made at our 33,000 square foot facility in the heart of Letchworth Garden City, Hertfordshire reducing the airmiles in our supply chain.
