Key UK Oil Refinery Coryton Closes Putting Jobs And Petrol Supplies At Risk | Business | Sky News (c) Sky News This is bad news, not just for the 1000 or so employed at the site. The refinery supplies c20% of all the oil in London and the South East. That capacity will have to be met from Esso at Fawley and TFE in Lindsey. There may be some additional supplies from Essar (Stanlow via the UKOP) and Valero (Pembroke via WENSAT) but in the short term at least there may be difficulties in obtaining oil supplies in that London Village. There will also be an impact on supplies to the four London airports. Until this morning, the company was the biggest independent refiner (by volume) in Europe. It had put three of its five refineries on the market after its bankers pulled the plug on its revolving credit line. Banks - too big to fail. Independent refiners - not too big to fail.
