KVA new build development

[Sponge bob big pants]

Wondering if anyone can help with this. My company has a new build development 12 x 2 bed semi detached. They have gas heating 1 electric shower en-suite, 7kW car charger. Roughly what would the average KVA be for these properties? Scottish power has come back with 2.5KVA per property but I think this is extremely low. Any help would be appreciated. Thanks

diversity... DNO's don't allow much

Tell SP you require 12KVA per house minimum and see what they say.

If they come back talking about network upgrade charges post what they say and I think I have a counter argument, that from "April 2023" they should not be charging such network upgrades to the customer.

Thanks ProDave, I did say 13KVA they came back with 5.5KVA I said that I still don’t think that is enough. Eventually they came back with 10KVA felt like I was haggling with them. I was just wanting to confirm I wasn’t over exaggerating.

They have gas heating so dump the electric shower, lousy things anyway and feed the shower from the (presumably) combi boiler.

Far better still fit a system boiler and an unvented hot water tank and you will have the king of showers from that, but developers are not known for spending a few extra £££ to make something better for the buyer are they?

Yeah was thinking of taking the shower away. Even with doing that I would still want it to be a bit higher than 2.5KVA.

Keep fighting them, particularly with the rating of the car charging point(s)
