2 electricity supplies to one building

Former Community Member

Hello, I am a not an engineer but need some advice on uk wiring regulations please. 

A national utility company is fitting a 32A charger in my garage for an electric vehicle. 

The garage is detached from my house but there is an existing circuit from the house consumer unit to the garage for lighting and a power socket. The cable runs along a garden wall. 

The new charger will have its own cable run from the same consumer unit in the house down to the garage. 

My problem is that the engineer who came to do the installation refused to do it as he said the garage is a building in its own right and regulations do not allow 2 supplies to one building.

My question is: Do 2 wiring circuits from the same consumer unit constitute 2 supplies If the consumer unit is located in an adjacent building? 

I would have thought that this was still a single supply and to have 2 supplies you need 2 separate meters with 2 consumer units which is not the case here but then, as I said, I’m no engineer. 

Edit.....The engineer stated that the regulation related to avoiding the risk of a voltage between 2 different earths. To me this again only makes sense if you were talking about 2 totally different supplies from different meters and therefore possibly different sub stations etc.

    EEEhh Lyle, I know that situation only too well.


    I used to get accused of all sorts by people jumping to wrong conclusions. I deliberately never corrected them in detail (I just said no i did not and left it at that.).

    If, however, they actually asked if I`d done/said such I would explain to them in more detail.. If someone said "You must have otherwise you`d prove it. I avoided proving it. I can be awkward just for the crack of it.


    I have noted people saying things that they have misundertood .

    One example a few years back was "The Building inspector said he had used the wrong cable!" wheras I said "no it is not!" When the building inspector turned up later I asked him what he`d said about the way the previous electrician had wired it and he replied "He had used larger cable than he needed to,( which I thought was a good plus thing for future resiliance)"


    So the meaning was misunderstood.


    Another instance.

    A relative was so concerned that he contacted the local council. 

    He had split from his partner and the children lived with her.

    She had got her brother to build a strong floor in the loft and a ladder via the bathroom..

    His main concern was kids falling down from loft to bathroom when using ladder.

    The Council inspector replied to him something like 1/ she said the kids are not allowed to go up there (he knew this untrue as kids tell you everything)

    . 2/ she said it was just to store as few light things.

    The inspector added that the floor that was very much more than strong enough to hold what she had stated.


    He was upset that the inspector had accepted her explanation .

    I read it. then read it again.


    I told him that my initial reading was like his but told him to read it again.

    I explained that the inspector was actually pointing out that the floor strength exposed her story as likely to be false.

    Bingo the inspector did in course get her to remove it.
