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.
I told the DNO that the maximum demand on the flats I mentioned was 40 amps, they fused their supply at 60 amps and I fused the distribution circuit at 40 amps though the cable is sized to take the full 60 amps. No one has ever blown a fuse, I left spare 40 amp fuses cable tied to the tails just in case someone did something silly and they are still there.
I used to do some work for a central heating firm and told a customer to unplug some electric heaters they were using whilst the boiler was being replaced as they had a 40 amp DNO fuse, apparently they ignored me and the fuse blew about a hour after I left and it took the DNO around eight hours to get to them at nearly midnight. That was only because they were trying to heat rooms they weren’t actually sitting in, which was just silliness.
In the next field to where I am eating lunch there is a run 11kV two phase overhead cables with a pole mounted Tx supplying a farm. Several years ago the farmer had a firm survey for a solar PV farm, but the DNO said no because the local 11kV network is maxed out and running at near full capacity. The farmer does now have a small array of panels on a shed roof that feeds into onsite storage batteries, that’s all that could be connected to the local network.
A LPG gas tank can always be buried to supply the new house that will be built, the tank does not have to be visible.
