The end to the escalator was announced on 9 November 2000, following the UK fuel protests, of which it was a contributory factor. When the escalator ended, fuel in the UK was the most expensive in Europe, with fuel tax representing over 75% of the retail price of fuel. In 1993 UK fuel had been amongst the cheapest in Europe
On the 23rd of March 2011 the government announced a number of tax changes which could affect the price at the pumps. There was an immediate £0.01 per litre cut in the hydro carbon duty rates which meant duty fell to 57.95 pence for both petrol and diesel. The Government also announced a “fair fuel stabiliser” policy which stated that when the price of oil was above a target price (75 USD was proposed for consultation) as it was on 23rd of March 2011, fuel duty would increase by CPI inflation currently 4.4% per year (5.88 pence based on an average price of unleaded of £1.34 for that day) starting on the 1st of January 2012. The fuel duty escalator which was abolished was based on CPI measure of inflation and the Government has also said that if the oil price were to fall below the target price on a sustained basis then they will increase the duty by RPI plus 1 penny. Using RPI rather than CPI at today’s rates for both would see an increase of 1.49 pence per litre because of the change of indexation measure alone.
