Extend new circuit from outhouse into another property with an existing supply, which is bad idea or not allowed?

Former Community Member

So there is a wooden outhouse with a consumer unit of its own with RCBOs in it that gets it supply from Building A using a 10mm SWA. Building A has a 3 phase 100A power supply. 


Building B needs a new socket for some domestic appliances but has no sockets that can handle the demand in the room where it is required (dishwasher and washing machine).


Due to layout of land and location of consumer unit location for Build B (which has its own single phase existing electricity supply)  it is easier to run a SWA from the consumer unit of the wooden outhouse into Building A. So Building B is using electricity supply of Building A through the consumer unit of wooden outhouse. 


I know there are some concerns about earth bonding potential differences but what options do I have? Can I just get electricity supply from the outhouse to Building B and extend and use the earth of sockets already in Building B? 


Is something I am doing here not allowed?

    Existing sockets are part of a ring for the power sockets for the whole house which is shared by several appliances including a massive boiler. Adding these extra appliances will far exceed the rating for the power supply and the building has concrete floors with tiles on them and brick walls with no insulation. It is also 3 rooms away from the consumer unit which makes it much more effort intensive to run a new circuit to it.

    Presumably as gas or oil boiler - not fully electric? So the ring is only supply the pump & controls - so likely load probably less than an amp?


    What sort of floor area are we talking about for the whole house? 30A rings were originally designed for 1000 ft² post-war houses with no thermal insulation with electric heating used simultaneously in two or three rooms.


    Would it make sense to split the ring? E.g. a couple of new cables to some point on the existing ring (hopefully nearer the CU than the new appliance) back to the CU and turn the single ring into two?
