Hello all,
I am about to receive planning permission for 6 one bed flats conversion from an existing family home. The current single phase 100A supply will not be sufficient so I have applied for a 3-phase upgrade.
My question is on maximum electrical load per flat.
I have done a similar project in the past where the 69kVA was sufficient for 6 flats. This house is double the size however the electrical demand is the same. SP Networks are asking what the load would be per flat (all identical) and how much I would like for the LL supply.
Am I wrong to assume 11.5kVA is enough for each one bedroom flat?
The landlord supply will have just four or five lights and some sockets. The flats will all be electrically heated with 2 x 2kW panel heaters, electric towel rail and 9.5kW powershower. They will have ovens, 4-ring hobs and extractor fans, washing machines and fridge/freezers. There will also be a 15L undersink water heater which will supply hot water to the sink and basin in each flat. That's it.
It works well in the other project with no issues on the 69kVA supply. Would I need to consider anything else or are my assumptions incorrect?
Thank you in advance!
James
