Diesel, ultra-low sulphur · per litre · 1940 Estimated
What this series measures changed. ONS changed what this series measures in February 2000: earlier figures price Derv, later ones ultra-low sulphur diesel. The two ran level across the switch, so the history is continuous — but a comparison spanning February 2000 is not strictly like-for-like.

Price history
Record & method
No price was recorded for 1940. This figure is estimated: we took the earliest observed price (January 1977) and moved it back along the category inflation curve — a back-cast of 37 years. The further back it reaches, the less it should be trusted. Treat it as an approximation, not a historical fact.
