Supplementary bonding questions

[GaryinAshby]

Our house was rewired in '99 just before we bought it & from my own limited experience seems to be reasonably well done. BUT, what are the modern requirements for bonding? I would like to ensure that the bonding is up to todays standards.

There is a (what looks like) 6mm cable from the box to the gas pipe & similar to the water main. What other bonding should I be looking for? Under each sink & bath? Radiators? Hot water cylinder? Other water pipes?

Best check with a sparkie - but at the very minumum I would do your bath and sinks, also cross bond all your heating pipes, gas, oil pipes and make sure you have at least one return to the main earth on your consumer unit - but I am not an electrician

look at "main" and "supplementary"
