When building a single dwelling it's common the the DNO "builder's" supply to be re-used as the permanent supply to the dwelling when complete - it might involve a move of the cut-out/meter at some stage, but the main cables from the street and connections into the the existing main can remain unchanged - usually with a corresponding saving in overall costs. It's unlikely the temp supply will need to be larger than the permanent one - so the initial request relates more to the final building than the builder's immediate needs. So +1 for taking to the DNO - but in the context of what will be needed eventually as well - it may well be cheaper and quicker in the long run.

Note that some DNOs offer 80A supplies as standard these days and may charge a lot more if you ask for a 100A one - just something to keep in mind if you don't really need the extra 20A.

I couldn't zoom in on the plan to see the details - but are those detached garages towards the top (North) of the plot? Just wondering if they'll need EV charge points...?

It seems that the yellow Es on the map will be the EVCPs. More detail here.

Somehow I struggle to see the tenants of such modest homes driving EVs any time soon.

I don't see why.  Assuming the stereotype older person down-sizing from a larger house, they may well have enough money for a decent second-hand electric run-around.  If they only do short journeys, it's less hassle than a fossil fuel car.

Perhaps not initially, but the need to charge EVs is very likely within the life of the homes and the electricity supply should allow for this.  Presuming a common 7kw charger that suggests a 100 amp supply unless other loads are small and expected to remain small.

An EV charger is a long hour load and no diversity should be applied. So that only leaves about 70 amps for general use.

If EVs are an option then Solar PV should be also tabled and potentially Electrical Energy Storage Systems.  This gives rise to a further discussion which results in a 3 phase supply to each dwelling.  Thus allowing for 22kw EVSE to be installed.  There are a lot of new build estates in the UK that are being built with 3 phase installs to the dometic dwelling. 

Save that they are in Wallsend, not Jesmond; and the client provides affordable homes. Any road, the Metro is only a 10 minute walk away.

Hi Chris,

It is a building regulation requirment (Part S) that all parking spaces associated to the property  are fitted with an EVCP.

Ah has that changed, I thought it had to be ready to accept one if needed and only needed if it could be done for less than 3k ?

That may of course apply. It does suggest that getting supplies put into the garages and then into the house may be the easier way, and then as per Aligarjon's post,  if the temporary site supply can be centered on the plot for one of those garages you do not need anything to be pulled up and moved when it is all over.

As before though ask the DNO - they should already know what they are putting in for each house.

Mike.

Mike,

they are no garages on this scheme....

Part S  has caused a headache on some current housing  schemes we are doing as due to the nature of the site the architect couldnt get parking space adjacent to the house causing some lengthy cable runs and chunky cables.

apologies - I assumed the small brown rectangles between the red houses were. Hmm. harder then.

Still worth angling to locate the feeder so that it becomes a house supply in the end with minimal effort.

Can you hire a generator while construction work is carried out ?  They even do site cabins with them built in. Quick search online “From 10kVA to 4.5MVA, we've got generators for projects of all sizes”.

So it is! (w.e.f. 15 June 2022) Thank you for the update.
