2.41 As part of the contract, BT provide a separate management service, for which a separate charge is made. Mason Communications told us that they would expect such a charge in a typical telecommunications outsourcing contract to be some 20 to 30 per cent of the total annual cost. We estimate that total management charges could represent as much as 44 per cent of the total contract charges. This is higher than the typical range, but these are Department specific services and Mason Communications advised us that meaningful comparisons with other organisations are not possible. Excluding charges for BOXER and UNITER, which have high labour elements, we estimate that management charges are 26.5 per cent of the costs of other services.
