What is the duty rate for super unleaded and/or lead replacement petrol?
Since Budget 2001, higher octane fuels such as these are charged duty at either the unleaded or ultra low sulphur petrol rate, depending on the sulphur and aromatics content of the fuel. This decision was taken following an environmental assessment (published on the Department for Transport website), which showed that higher octane fuels were generally no more polluting than the lower octane alternatives.
