Screwfix has halved its operational emissions in four years while expanding stores, backed by third-party verification. But Scope 3 supply chain emissions remain unmeasured at subsidiary level, and water impact is entirely unreported. Transparency relies on parent Kingfisher's group reporting rather than standalone disclosure.
Screwfix scores 45/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.
That places Screwfix joint 283rd of 947 companies scored, and joint 10th of 50 in Retail (non-fashion).
