Have a query regarding bonding for periodic.
1, Main protective bond for gas supply goes to the supply box outside the house, is this ok as would be difficult to connect it in the house close to the supply as it goes under the floor. If it is a problem what code ?
2, supplementary bonding below boiler 10mm (4 pipes all connected 10mm looks very neat with labels) but then goes into the a fused switch that feeds the boiler, so have a tight fit 1.5mm cpc along with 10mm going into the earthing connection. Is this ok, reading of the bonding to CU is still good 0.05 ohm, is this ok ?
