Responsibility for installing Main Bonding Conductors

[scanner]

Bugger that's supposed to say BONDING not BOINDING !

-----------------

I've been asked to install a new CU at my mother in law's.

She has recently had a new kitchen installed where new lights, and extra sockets were added (circuit extended) for the fridge and (gas) cooker.
These sockets BTW are surface mounted 2 gang boxes but are just laid on the ground underneath the kitchen units.. they actually look like they've just been slung there.

Apart from workmanship, my concern is that I can see 2 x 10mm bonding cables leaving the old consumer unit and disappearing through the wall towards the kitchen.

I've found the main gas valve (in the kitchen) but there is no bonding attached. It is also impossible to find the main water valve as the whole back of the unit under the sink has been boxed in.

My question is:

If electrical work such as this has been carried out, is it the installer's responsibility to ensure bonding is installed even though nothing was done "back to the board"

I would have thought this would have fallen under notifiable work as it's in a kitchen. As it stands they didn't receive any certification at all.

It also doesn't fill me with confidence that the feed to the under counter lighting has exposed insulation ,

It's a fifth floor flat and the gas meter is downstairs. According to reg 544.1.2 main bonding should be attached as close as reasonably practicable to the point of entry of the premises.

At the moment I can't see any !!!!.

Any advise would be appreciated.

Should I give the installer a call to give him a -------ing… or should I just go ahead and rip her nice new kitchen out ?

Any advise would be appreciated.

Thanks,

Al

So no Certificates, no Notification, no RCD on final ring circuit alteration, no bonding to gas, sockets chucked under the units.

You can see why some companies want to get kitchens made non notifiable under Part P MK2, complying with regulations is so costly. - :smiley2:

here is something for you reguarding the max 0.05ohms on a bonding conductor. We were doing work at a college, there was no boinding in place and had multiple points to bond. Some were mega distances away and have always selected them with regs and the 0.05 sum. Anyway the supply is TNS so the bonding conductor size is 25mm max due to supply caracteristics ect. Some of our runs were working out to be 120mm. We contacted the IET and were told the 0.05ohm is a falicy and they dont know where it cam from and as stated in the regs the maximum size of a bonding conductor for tns is 25mm MAX

I would be straight on the phone to the kitchen company and/or trading standards, if they have done the work themselves they should be part p defined scope at least or if they have used a sparky then you would expect them to be part p full scope
