Anglian Water scores 41/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.
That places Anglian Water joint 330th of 799 companies scored, and 7th of 11 in Water & Sewerage.
Anglian Water's gross reported emissions rose from 265,219 to 297,156 tCO2e between 2022/23 and 2024/25. Its reported Scope 3 covers three categories, and capital carbon is reported only as a percentage. Pollution incidents rose 44%, from 307 in 2023 to 441 in 2024, and its rate of 57.17 per 10,000 km of sewer was nearly three times its 19.50 performance commitment. The Environment Agency rated it 2 stars. It was fined £2.65m in 2023 for sewage discharges from Jaywick, the ASA ruled an environmental advert misleading in 2023, and in 2024 it was convicted of failing to provide records to the Environment Agency.
