DERV (commonly known as White Diesel/Road Diesel/ULSD – Ultra Low Sulphur Diesel) is a liquid fuel used in road vehicles and has the applied government duty to be paid. The DERV supplied by Certas Energy meets BS EN590 standard and is the most common fuel used by vehicles that operate on public highways.


BS EN590 standard means fuel may contain up to 7% biodiesel

Between October and March, DERV supplied is covered to temperatures of -12C with addition of a pre-mixed winter additive


Gas Oil

Gas Oil carries a lower rate of duty than Diesel and can be used in modern diesel vehicles for off highway applications, trains, industrial and commercial boilers/furnaces, stationary engines and light duty to medium speed marine applications. 


  • Clearly marked with a red dye to differentiate it from ULSD.

  • Class A2 specification is suitable for both diesel engines and furnace applications whilst the Class D specification is suitable for furnace applications, but not suitable for diesel engines.
  • It cannot be used for road vehicles.


  • Class D is significantly cheaper than Class A2 because it is priced from a different product quotation.
