§ Mrs. Roche
To ask the Chancellor of the Exchequer what was the average time the Inland Revenue took to answer letters(a) in 1979 and (b) in each subsequent year. 
§ Mr. Jack
[holding answer 12 November 1996]: The Inland Revenue does not collect information on average response times. Instead, it measures performance against its customer service standard of replying to all types of post within 28 days. These customer service results are published annually in the board of Inland Revenue report, copies of which are in the House of Commons Library.
