So earth at the CU should be bonded to the gas pipe as close to the entry

Yes.

Electrics around the combi should be bonded to the copper gas pipe.

No. The electrics are earthed by the circuit protective conductor to
the main earth terminal, and the gas pipe is bonded to the main earth
terminal. The boiler, if it requires earthing, will be earthed by the
circuit protective conductor.

Oh, and the gas hob should be bonded to the gas pipe as well.

No.

Probably anything electrical in theoretical touching distance of a gas pipe
(or the hob?) in the kitchen.

No.

Is there anything else that should be bonded?

No, according to 17th Edition.

If your bathroom wiring is to 16th Edition (i.e. not all circuits are
RCD) then you may need to equipotentially bond for the bathroom.




And the regulations are different for council houses. For council
houses it's compulsory to earth everything (including the individual
hot and cold taps). :-)


Umm ... why?..
