The owners of Stanlow oil refinery at Ellesmere Port in Cheshire are seeking to sell the facility, according to reports in the Financial Times.

India’s Essar Group, which bought the refinery from Shell for $350m in 2011, is in talks with a number of parties about selling a minority stake or the entire plant, it quotes two sources as saying, and is examining options to exit its UK operations.

Essar Energy is the subsidiary of the group that owns the refinery. Essar denied it planned to sell the refinery and pointed out it had invested in upgrading the plant.
