Answer for Congestion Charging and LPG Vehicles

Answered By: 
The Mayor

When the Congestion Charge was launched in 2003, TfL also introduced the Congestion Charge Alternative Fuel Discount (AFD).  This ensured certain low polluting vehicles benefitted from a 100 per cent discount from the Congestion Charge.  To have been eligible to register for the AFD, a vehicle must have been powered by an alternative fuel, including LPG, bi-fuel or dual fuel and not solely by petrol or diesel. 

My proposal and subsequent decision to remove the AFD was made, following public and stakeholder consultation and was primarily due to the advancement in vehicle technology that had taken place since the AFD was first introduced back in 2003.  This meant that the AFD criteria was outdated and there were a growing proportion of vehicles that qualified for the AFD but had relatively high CO2 emissions.  Conversely, other vehicles with lower CO2 emissions didn't qualify for the discount.  The AFD was closed to new registrations on 24 December 2010. Despite the AFD being outdated, I recognised that some motorists may have paid a premium on the purchase price of vehicles that qualified for the AFD.  That is why a two year 'sunset period' was set which meant that all motorists who were registered for the AFD on 24 December 2010 remained entitled to the discount until 24 December 2012.

The AFD was replaced, firstly by a Greener Vehicle Discount and more recently by the Ultra Low Emission Discount (ULED).   The new ULED was introduced on 1 July 2013, and is a technology neutral discount available for cars and vans of any fuel type that have CO2 emissions of 75g/km or less and meet the Euro 5 air quality standard.   For more information about ULED please visit:
