Bonding

Northern Spark

I need to install bonding to the gas services in a flat above a shop that has two electrical supplies and two gas supplies. The flat was two separate flats that have had a door put in between them, essentially making them one flat. Half of the flat is supplied from a single phase supply and consumer unit located in the flat, the other half is supplied from one phase of the shop's three phase supply, located in the shop. There are two boilers in the flat, one with gas supplied from a meter located in the flat, the other boiler supplied from a gas meter located on an external wall. (I think they have a common water supply, but haven't been able to confirm this yet. There is a 10mm bonding connection to the water supply). I presume this all needs bonding together? I am not sure on the best approach. Can I run a 10mm bond from the consumer unit to the two gas pipes and another from the 3 phase board to both the gas pipes? Or one bonding conductor from the consumer unit, to both the gas pipes, and then to the 3 phase board?

    Usual landlord nonsense.

    If the occupier is content with two lots of standing charges, why change anything unless there are simultaneously accessible conductive parts? It does not seem very different from two flats off a common landing.

    If the aim is to avoid standing charges, there will be only one of each supply, so no requirement to bond them together.

    Perhaps the aim is to allow the flat to be redivided if necessary in future?

    If you were going to connect the two supplies, you would want to be certain that they came off the same transformer.

    If it's a rental property, then the occupier has no say in the matter.

    Perhaps the easiest is to make sure that sockets and radiators on metal pipes, for the two halves are not easily within touching distance (a couple of metres ) of each other - tape measure through the doorway and all that. Any light switch can be the plastic kind where the screw heads are covered.

    It may end up being be far easier to move or blank off a socket than it is to combine the installations. It rather depends what is near the linking door. As others have said it is not without precedent with flats that share an entrance hallway and so on. It is possible for someone to bring an extension lead from one side to the other of course, but things on long cords like vacuum cleaners, lawnmowers, jetwashers and so on are normally double insulated these days and if there are enough sockets on each side, why would they need an extension lead at all?

    And if they are the sort of tenant who unscrews the cooker point to get a high current supply for something like a welder, well there are probably other issues and this is the least of them.

    At some point pragmatism has to be used.
