Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many Access to Work reconsideration requests submitted by (a) blind and (b) partially sighted customers have resulted in the original decision being overturned in each of the last three years.

We do not hold this data in a way that can be extracted.
Determining this information would require a manual review of all individual reconsideration cases, which would incur a disproportionate cost.
