Ofgem has given preliminary approval to a modification to the Uniform Network Code that would reintroduce the short-haul discount that was removed as part of the revamp of gas transmission charges which took effect at the beginning of October. UNC728B would provide a discount of between 10 per cent and 90 per cent on gas transmission charges for users connected within 28 kilometres of an entry point to discourage them from constructing their own pipelines to bypass the network.
