butler,

why do you think you need to "cross bond" the pipes on the boiler? and what size cable do you think you need?

tell us a little and we will help you work out the answer,

My dad has no bonding on his combi boiler and I though that the pipes connecting it to the gas and water would need bonding he has. TN-C-S PME and I think a 4mm or 6mm would be needed but I don't no so I'm asking would it need bonding

Thanks

There is no requirement to cross bond the pipes on the combi boiler, the pipes are normally connected in earth terms by the yolk holding all pipes in place. Providing there is bonding to the main gas and water intake positions, and no potential differences occur within the location of the boiler then it would not need bonding.
