No one appears to have tried to respond yo your query Hugh! The figure you refer to sounds unusually high. Did you calculate it yourself? Does it include expensive projects like burying cables? If you got the information from the utilities I wonder if they included costs that they are normally expected to meet themselves or if they are simply inflating the figures. Some years ago there was an EP Report trhat waxed lyrical on that problem. In any event CIL cannot be differentiated by costs so it seems to me that you have two options Either you impose the extra cost on everyone, or you break down the infrastructure needed into packages that can be funded through S106 under the '5 instnaces' rules.
