Question to the Department for Transport:

To ask the Secretary of State for Transport, what the value of uncollected vehicle excise duty was in (a) 2011, (b) 2012 and (c) 2013.

The value of uncollected license duty in Great Britain was estimated to be £40m in 2011/12 and £35m in 2013/14, representing 0.7% and 0.6% respectively of the total road tax payable in each year. These estimates were derived from a DfT survey of unlicensed vehicles on the road carried out in alternate years, therefore no equivalent estimate is available for 2012/13.
