Large house

The standard supply for a new  house seems to be circa 18KVA single-phase. I have a client who needs to make application for a supply for a new build house at 400m2 with the only certain information being that an air source heat pump is to be used for heating. The client simply does not know what the electrical loading might be. The house is only coming out of the foundations but the DNO supply may take many months as the house is in a relatively remote rural location, thus loading details are required before the DNO will consider progressing the proposal. It is a big house, but that is what it is, just a big house. I am inclined to advise a standard supply but 3-phase as with a large AS heat pump, maybe shower, cooking and perhaps an EV or two, 18KVA wouldn't be long being gobbled up. As we move towards a higher reliance on electric as a power source for some heavy current-using equipment, it might be that 18KVA is no longer a realistic standard supply for even the smaller property.
  • An Ecotricity charger at a motorway service station will cost £3 to connect for up to 45 minutes, plus 30p for each kWh of electric.

  • If you’re transferring all your motor vehicle fuel expenses onto your home electric bill along with your water and space heating costs it has to be a significantly higher bill than most people currently pay.
  • When it comes to the cost of fuel, don't forget that domestic energy is taxed at 5% VAT. Petrol and diesel have their own taxes (duties) with 20% VAT on top of both the fuel and the tax. Even your tax is taxed! ?
  • A car with a petrol engine may have double the resale value of that car I linked to, there seems to be a big hit on the depreciation for a low mileage car.


    Possibly because of the fifty quid a month “fuel” cost before you even start it up, payable as the lease on the batteries.
  • LOL.


    The asking price for a Secondhand battery  on EBay is more than the price of the car.
  • Without battery, you need to rent a battery from Renault.

    I think that was a Renault peculiarity - and one I gather they now backing off from - most EVs come complete with a battery set as part of the purchase price.

    Renault have abandoned leased batteries on all new vehicles.  The battery is included in the price.

    Mind you there’s some Wonderful equipment for reducing electricity bills.
