Be aware that they will only reconnect your supply after the work if
your water & gas/oil are bonded.



and IIRC to current (continuous 10mm) standard

What does 'continuous' mean in this context? Surely it doesn't mean no
joints? Or does it means no thinner sections?


It means if your water bond is on the way to the gas, so you do it all in one length, make sure it is one length(not cut). That way if someone disconnects the water bond, gas is still bonded.

I think I learned that here, but I've seen it referenced elsewhere too.
