The EU has directed the UK to remove the “derogation” on avgas, increasing the cost significantly. Following negotiations by the LAA and others, the Treasury has proposed to define avgas a specialist fuel (as opposed to lumping it in with motor fuels) reducing the impact of this significantly. However, Jet A1 for private use would become taxable. See the consultation document for details. The LAA will submit an omnibus response generally supporting the proposal but you can respond yourself if you wish.
The deadline is 31 October 2007.
