Is it cheaper to tax an LPG-fuelled car?

Does a 3.2 petrol engine converted to LPG, a 2000 model, qualify for a tax reduction based on CO2 emissions being certified by the NCT centre?

Hi Tommy,

Sorry, but no. As far as Revenue and the motor tax system are concerned, a car will always be taxed on its original, homologated figure, whether that be the engine’s swept capacity or its CO2 emissions.  An LPG conversion is considered an aftermarket modification and so isn’t taken into account for tax purposes.
