The low price of LPG at the pumps was guaranteed until 2009 by the Chancellor in the 2006 budget with duty differentials only being reduced by 1p per litre per year for the period. Dualfuel vehicles have the additional benefit of receiving 100% discount from the £8 per day London congestion charge including the recent extension into West London, that’s a saving of up to £40 per week. With a three year/100,000 mile warranty included as standard on all new vehicles, and one year/60,000 mile warranty on used vehicles the Dualfuel conversion now has additional peace of mind built in.
