Equipontal Bonding Gas Main (plus other pipes?)

[Coaster]

Hello all,
just a quick question.. i've little time to get online so apologies if I take ages replying..

Basically, I am planning to fit an earth from the gas pipe (within the 600mm rule etc.. )

I have noticed that the central heating and the hot water system dont have a bonding.

So.. could I do the following and is it a good idea to do? being a bit fik and not understanding equipontal bonding thoroughly.. anyway is this acceptable? ;

external bond strap from external gas pipe at Meter ---> through wall cavity and into loft --> bond strap on one of the CH pipes out of tank that circulate to rads. --- > another bond strap on hot water supply to taps --> down inside stud wall ---- > Main earthing block thingy using 10mm2 earth wire, not cutting the wire but by cutting off insulation, then making a gap in the strands to fit intermediate bonding straps.

Any comments?

You only need to bond extraneous metalwork, so basically any metallic service which enters your house from the street.

Normally this is just the gas and water supply.
