544.1.2
"connection...As near as practicable to the point of entry...on the
consumers hard metal pipework...before any branch pipework....within
600mm of meter outlet union, or point of entry if meter is external."


Thanks Alan. Yes, reg 544.1.2 seems to leave it open as it whether the
bonding is inside or outside (where, as here, it's a simple case of a
pipe through a wall, nothing buried etc). But there's also the gas
regs. If there's no bonding visible in the meter cabinet a gas fitter
may mark it "Not To Current Standards" based on GasSafe's
view of the gas regs
(http://www.gassaferegister.co.uk/pdf/Gas_Industry_Unsafe_Situations_Procedure.pdf)
The bonding has also to be accessible and the pipe inside the house is
difficult to access as it enter under a corner of the living room floor.
So I thought
I'd take the opportunity while the floor's up to loop through from
inside to the meter box and try to keep everyone happy.
