Two houses, one supply

[young sparky]

Hi all,
I usually do a lot of industrial work, (schools, hospitals and factories etc) but have wired a few houses in my time!
Currently wiring a new house at the moment and the lady I was wiring it for asked me would I speak to the electric board when the call out to the house, they have quoted her around £20,000 to bring a new supply from the nearest transformer to her property, approx 240meters away.
after discussin with the electric company and client he has told us that we could bring a supply from her neighbours house (clients brother) to supply her house which is aprox 40meters away, and talked about putting on a separate meter to calculate units used and split the bill accordingly
all this would have to be done by myself as it would be nothing to do with the electric company as it is a private meter and they are only concerned with anything up as far as the current meter
havent seen in the neighbours yet but should be at least 80 or 100amp supply to his house, but has any1 ever seen or done anything like this, been just thinking about it and problems that could occur with this, any advice welcome, thanks

Sorry if this is an obvious thing but surely 80 amps wouldn't be enough for two houses?

A shared supply will cause problems if either house is sold in the future and would cost more than £20k to sort out.

Lol, I know, I would be splitting the tails before the main switch of the first house, I think the guy from the electric board said it was a 95mm supplying the first house from the transformer, this may sound like a silly question tho but I have never seen this done or done anything like it before

Yes snowhead, considered that also, but at the moment it's the way the customer wants to go about it

In which case I would suggest you decline to get involved...........

and what happens if its a 60A DNO fuse?

It would be plenty assuming they are normal houses.
You average house will be happy on around 20/30 amps

Wouldn't there be adequate capacity on the DNO cable to joint off a new supply from near where it enters the existing house ?

You'd think so wouldn't you?
It stands to logical reason that if the DNO engineer has said that a second house can be fed off of that supply then there must be the capacity there to do it.

Our last house had our neighbours house 2 daisy chained" off our connection. We found this our when we had an extension and the UKPN chap turned up to move the meter and head!
