New Build Supply Issue
Former Community Member
Has anyone here had an issue getting a connection to a new build, due to a substation being at full capacity? We are building in a residential area, albeit rural and on a plot of land that did have a property on it, although some years ago and upon requesting a temporary supply, the surveyor has informed me that I will have to pay to upgrade the network. When I asked about costs he said it could be anywhere from £10k to £100k. Obviously in a bit of a panic and thought I’d reach out to you experts and see if anyone could advise or alleviate my fast beating heart rate! Also, to ask if the old connection would have any bearing? Many thanks all.
Just a comment on the subject of DNO service fuse size.
The design standards of each DNO (Distribution Network Operator) and IDNO (Independent DNO) may/do vary. The installation of a new single phase service, and cut-out, may be fused at a rating of either 60,80, or 100amps, respective to that particular DNO/ IDNO design standard.
However, the service fuse size does not have a direct relevance to the capacity you have declared. I.e. if the DNO have agreed to provide you with a single phase connection of 10kva capacity to meet your declared Maximum Demand, then if that DNOs standard is to fit a 100amp fused cut-out, then that's what you will get.
Understandably, this does lead to some confusion, and I have often found customers are under the false apprehension that the size of the service fuse dictates their agreed capacity, or indeed the available capacity.
The ramifications of this issue tends to be more of a problem in rural areas where Transformer and LV network capacity is often limited.
