Although Bone was not mentioned in the 2009 "Legg Report" that was central to the official investigation into the United Kingdom parliamentary expenses scandal and therefore was not one of the 343 MPs required to pay back any money, he was subject to some later reports relating to his expenses. He was one of 32 MPs who claimed the maximum allowance of £4,800 a year for food in 2010 and came under investigation in 2014 for expenses claims relating to the upkeep of his second home. In 2016 he was reported to be one of 26 MPs who had expenses debts of up to £500 written off after failing to pay them by the Independent Parliamentary Standards Authority and in 2016 was criticised for using the government's help-to-buy scheme, which was meant to help young first time buyers, to buy himself a new constituency home.
