<p>There are around 800 third party suppliers of services to the House of Commons and given system changes in recent years it would involve disproportionate cost to derive precise figures of contract expenditure by financial year. It is estimated that expenditure has broadly been equivalent to:</p><table><tbody><tr><td><p>Year</p></td><td><p>Amount (£m)</p></td><td><p>Proportion of spend (%)</p></td></tr><tr><td><p>2009/10</p></td><td><p>92.7</p></td><td><p>32.6</p></td></tr><tr><td><p>2010/11</p></td><td><p>87.4</p></td><td><p>47.4</p></td></tr><tr><td><p>2011/12</p></td><td><p>90.7</p></td><td><p>43.1</p></td></tr><tr><td><p>2012/13</p></td><td><p>89.0</p></td><td><p>40.9</p></td></tr><tr><td><p>2013/14</p></td><td><p>83.7</p></td><td><p>37.0</p></td></tr></tbody></table><p>For 2014/15 the planned amount is around £100 million which represents 40.8% of the combined capital and resource budget.</p>
