A Non-Executive Director of Utilitywise, a cost management consultancy, on Tuesday acquired just over three million pounds-worth shares in the group. Jeremy Middleton, who co-founded emergency repairs business HomeServe, bought 1.15m shares at 260.22p a piece, significantly upping his stake to a total of 1.79m, equal to a 2.48% stake. The group has seen the value of its shares rise strongly over the past year, climbing from around the 100p mark to yesterday's opening price of 260p. This was in part driven by a strong set of full-year results for the 12 months ended July 31st, when it reported additional revenue and profit resulting from a reassessment of the discount rate used when fair valuing revenues. News of Tuesday's purchase helped push the share price a further 30p or so higher.
