Follow up question: quote for connection and local supply issue

Morgan Phillips
Thanks for the fantastic replies I had to my previous question, helping me to understand the supply locally and enabling me to successfully push back on the quote/plan provided. 


I now have one further query.


WPD say that if they were upgrading the local network they would overlay the current 95mm wcon cable with a 185mm wcon cable, but that this alone would not be sufficient to allow for my property to be connected to the local network. Instead, they said that for me to be connected, a 300mm wcon cable needs to be laid, and they want me to fund the difference between the 185 cable and the 300 cable. 


As they were less than scrupulously transparent in their previous quote, I would like to check if anybody has any thoughts on the veracity of this? Why would upgrading to a 185mm cable not allow sufficient capacity to add my supply? Why would they not, if doing an upgrade and presumably incurring significant cost, simply upgrade to future proof the local supply with a 300mm2 cable?


I'm particularly concerned that what they have said about replacing the 95mm2 cable with a 185mm2 cable (that this would not be sufficient to connect me to the supply) is untrue.

    Many thanks BOD and Chris. It seems it is less straightforward a question to answer than I had originally thought.

    Whilst I do not dispute at all the need to pay for the supply connection, given my earlier experience with WPD I am cautious about accepting at face value the things they say about their supply and the way the costs are divided up. 


    It's really helpful to learn that the capacity of a 185mm2 cable is much less than I had thought. My assumption was that if a 95mm2 cable can feed a whole street (which it currently does), then adding a 185mm2 must provide a lot more. If they are having problems locally, then I can see how this would potentially use up a significant amount of the available capacity. 


    It would be helpful to better understand why they would not consider upgrading it as a matter of course, given that they are going to pay to dig up the neighbour's garden, and I may well go back and explore that a little more. After all, they know they are going to have to expand capacity even further in the coming decade.


    Have a restful evening.
