Due to the volume of data required to answer the question in respect of appeals against special education needs decisions made by local authorities, I will arrange for this information, broken down by local authority, to be placed in the Library of the House.
Information on the cost to the public purse for these appeals prior to the 2015/16 Financial Year is not available at this time, but I can confirm that the total cost of the operation of the First-tier Tribunal (Special Educational Needs and Disability) (FtT SEND) was:
In 2015/16 - £2,983,418
In 2016/17 - £3,347,986
In 2017/18 - £4,008,647
