Hi all.

Went to look at a little job for a friend (rented property). New fan to go in bathroom outside of zones. Easy job to put the circuit onto 30mA RCD. TT system, water bond ok. Problem is the lack of gas bond to the property, and it's a proper pig to get one in. It's had a board change <10yrs ago and a new boiler etc, so I'm wondering why this hasn't come up as an issue before. The gas will be (I'm assuming at this stage) connected to the MET via the water pipe bond and boiler cross bonds etc, but I'm not overly happy about signing off on such an arrangement.
What would you do in this situation?

Kind Regards

id bond the gas by all means possible.

Difficult is everyday.
Impossible just takes a bit longer.

What are we talking about? flat? house?
Where is the meter in relation to the CU?

Thanks Pete,
It's a mid terrace house, consumer unit halfway upstairs on right of house. Gas meter at front left. Not impossible by any means, but it's decorated, etc. Also, the letting agency's spark has priced for the fan but hasn't even looked at the bonding prior to quoting (he hasn't turned up to do the work, hence the call for me to have a look). I can guess who's (cheaper) quote they'll still go for....

Kind Regards

So ok then.

Just guide them towards the ESC links on consumer safety and bonding etc to illustrate your very valid points.
Good luck with this one!

Is the gas service plastic?
If so the danger is minimal if the gas is connected via boiler etc.
Bonding in a TT installation is rather different to your average TNCS installation with metallic service pipes.
