Since 1 April 2005, hon. Members have been entitled to claim mileage allowances in line with Inland Revenue rates (now HM Revenue and Customs rates), which are 40p per mile for the first 10,000 business miles travelled in a year and 25p per mile thereafter. This was decided by Resolution of the House on 3 November 2004. The Resolution was in line with a recommendation by the Senior Salaries Review Body of October 2004, Cm 6354-1, paragraphs 4.50-52, which gave the following rationale:
"The approved IR rate is calculated to represent the actual cost of motoring, including fuel costs, wear and tear (including servicing and depreciation), road fund licence, and insurance. We received no evidence to justify why MPs should be entitled to a more advantageous rate."
