Hi all.

Apologies of this is in the wrong place.

I am looking for some advice. I had a new consumer unit in 2016 which is fine however I have just noticed an earth wire coming out of the bottom which isn't connected. I'm not sure if I has always been this way or not?

There is another earth wire running along the top connected to some piping so I'm not sure of that's why this one isn't connected?

Any advice would be appreciated. Didn't want to call an electrician and waste someone's time if it's not an issue plus if it just needs putting back somewhere I can do that.

Looks like the earthing conductor, also the head looks like TN-S sorted quite recently as that braid looks very clean.

Do you have any certification for the work carried out?

Get an electrician in to confirm.
 
I'm in mist of learning to hopefully get my 18th this year so correct me if I'm wrong but shouldn't the bonding be before any joints on pipework and within 600mm of meter
 
You may want to contact the DNO electricity supplier for advice, as it looks lie the Electrician that fitted your New CU has left the L and N Tails as well as an Earthing conductor and the DNO meter fitter ignored it, without seeing the complete installation it's hard to decipher, seems as though the DNO hasn't provided an MET Main Earthing Terminal, shoddy in my book, call them as a matter of urgency, the meter fitter want's Castrating without an anaesthetic, and with a blunt knife, for leaving it like that. Was mothing sai at the time of connection? or did the meterman leave his brains in the van, if he had any to start with. shocking work.

Was that a consumer unit fitted by “the boiler people”?
That kind of explains it.

The disconnected earth wire needs to be connected to the MET, main earth terminal, which in turn is connected to the suppliers earth.
I advise that you contact whoever changed the CU to find out why it wasn’t connected, and your supplier to ask the same thing.
You could connect it yourself, if you can see where it should go.... but an electrician would be able to say if it’s actually doing what it’s supposed to once connected.

It doesn’t appear to have any termination screw markings, which suggests it’s never been connected to anything.... rather than just falling out a loose screw.

It is a matter of urgency you have this investigated by a professional. You may not have an earth protecting your property if there were to be a fault.
