The government's Plug-in Car Grant scheme has been running since 1 January 2011. The chart below shows what the take up of the grant has been. Running your cursor over the chart will highlight exact values.
Note: since the beginning of 2015 the Office of Low Emission Vehicles have not been routinely publishing the claim figures on a quarterly basis so this chart will only be updated further as and when the data is available. In the meantime, to see how many Plug-in Car Grant eligible vehicles are on the road have a look here.
