A report on a house I'm buying says there "is no evidence of
equipotential earth bonding" of the incoming gas supply to the boiler.
I have also been told it needs an electrician to correct this.


What exactly does equipotential earth bonding mean, and how important
is it to have it?


It is a cross earthling of metal objects (pipes in this example)

At the boiler, all the pipes should be connected to each other with earth
cables and clamps, then at lease a 10mm cable sent back to the main earth
terminal (in or near the consumer unit). By what you have posted, it looks
like the gas pipe has been left out of this (It is very easy to rectify with
an earth clamp and a piece of 10mm earth cable).

Is for how important, it is required by the regs, but hasn't always been.
