The UK has 4 operational oil refineries in 2026: Fawley, Humber, Pembroke, and Stanlow.

Quick Scoop

Recent reporting in 2026 says the UK’s refinery count dropped to four after the closures of Grangemouth and Lindsey, leaving those four sites as the remaining major facilities.

Named refineries

  • Fawley, Hampshire.
  • Humber, Lincolnshire.
  • Pembroke, South Wales.
  • Stanlow, Cheshire.

Context

These four refineries are reported to supply about 85% of UK market demand, so the sector is much smaller than it was a few decades ago.
