EN Plus A1 Wood Pellets
The Gold Standard for Quality and Sustainability
SDL Pellets proudly produces and supplies EN Plus A1 wood pellets, the highest quality class in the biomass fuel industry. This certification guarantees excellent performance, environmental responsibility, and consistent quality. That makes EN Plus A1 Wood Pellets the best choice for your biomass heating needs.
We know how important it is to keep standards high. EN Plus A1 certification is not just a label. Instead, It represents our promise of quality, sustainability, and trust. Here’s what the certification means for us, and why it matters to you.
What is EN Plus A1 Certification?
EN Plus is a strict certification scheme created by the European Pellet Council (EPC). It sets high standards for every stage of the wood pellet journey. That includes production, storage, transport, and delivery.
EN Plus A1 is the top quality class within this scheme. It shows that our pellets meet the most demanding standards for:
- Raw Material Quality: We only use wood from responsibly managed forests. All of our wood comes from FSC certified woodland as well so you can rest assured that it’s been sourced from responsibly managed woodlands.
- Production Processes: We keep tight controls to ensure low ash, the right moisture levels, and uniform pellet size.
- Energy Content: Our pellets have a high calorific value. This means you get maximum heat output.
- Durability: Pellets are built to handle storage and transport without breaking down. Because SDL Pellets manages the whole process from our production line to your door, there is less handling. As a result, dust levels stay low.
- Sustainability: We monitor every step of production to reduce environmental impact and support long-term sustainability.
Why Choose EN Plus A1 Wood Pellets?
Choosing this gold standard gives you several clear advantages:
- Optimal Performance: Our pellets burn cleanly and efficiently in your biomass boiler. This improves heat output and reduces ash buildup. In turn, you save money on maintenance and spend less time cleaning.
- Environmental Responsibility: By choosing EN Plus A1 Wood Pellets, you support sustainable forestry and lower your carbon footprint.
- Quality Assurance: Certification guarantees consistency. You can rely on every delivery to meet the same high standard.
- Eligibility for Incentives: Our EN Plus A1 pellets are also BSL certified. This means you qualify for the government’s Renewable Heat Incentive (RHI).
