20. XMA - £116m

The Nottingham-based reseller endured a tough time in 2011 as the challenges faced by public sector bodies ate into its sales. The revenue figure for FY11 was down almost £25m on the prior year, but operating profit held more-or-less flat at a little over £3m. The VAR suffered from the end of the Home Access scheme, a big-ticket project launched by the previous government to provide PCs to students from low-income families.
