Why Certified Energy Ratings Matter: How D.L Windows and BFRC Ensure Top-Quality uPVC Solutions


D.L Windows: Your Trusted Partner for Certified Energy-Efficient Windows and Doors

At D.L Windows, we are proud to partner with the British Fenestration Rating Council (BFRC) to deliver the complete range of Veka windows and doors—fully certified by this leading energy-rating specialist.

Our commitment to quality means we work closely with Veka and the BFRC, ensuring that every window and door we manufacture and install meets the highest standards. Unlike many companies that outsource frames and glass separately, we handle every step of production in-house. This means that our products, processes, and materials undergo strict BFRC audits, guaranteeing compliance with their rigorous energy certification requirements.

Why is this important for you?

Certified energy ratings are crucial for determining the efficiency of your new uPVC windows and doors. With independent verification from the BFRC, you can trust that our products will meet the exact standards your BER assessor needs to provide an accurate energy rating for your home.

Every window and door manufactured by D.L Windows using Veka profiles can be independently verified on the BFRC website—giving you complete peace of mind about their quality and performance.

Choose D.L Windows for energy-efficient solutions that don’t just meet expectations but exceed them. When it comes to uPVC windows and doors, trust the experts who deliver only the best.
