Calculating Power Requirements For A New House After Diversity

[pemills]

Hi all, I am not an electrician by trade but need a answer, if possible, as to how best calculate the power requirements for a new house that I am building, my electrical network supplier has asked me if I can tell them what the house will require after diversity, as I do not have an electrician on board yet I am simply trying to get the network (UK Power Networks) to give me an approximate price for supplying the house with a single or 3 phase supply.

I appreciate there will be a need to calculate this once we have a full spec for the house, which will have a ground source heat pump as well as all the usual electrical white goods, gadgets and gizmo's but getting even a ball park figure for budgetary purposes is proving to be a little difficult , can anyone help me please?

Thanks in advance

I would ask for a single phase 100 amp supply and see what they say.

Given your list the house would never get near that limit.

Also get yourself a sparky lined up sooner rather than later

I'm with Murdoch on this.

Cheers guy's I have been in touch with a couple of sparky's and I will be engaging one sooner rather than later but UK Power Networks new connections dept are still asking for the KVA requirement!!

100A would be 23KVA

Perfect, thanks, that will give me something to work with

What's the electrical rating of the planned ground source heat pump?
