You don’t necessarily need to upgrade any protective bonding conductors , just need to verify they exist if required and are satisfactory.Yep, 100% it is on a 15amp fuse, earthing of lighting circuit is satisfactory, but am unsure why I need to upgrade bonding???
If extraneous conductive parts exist within the installation and do not have any protective bonding conductors Connected to the MET then your work can not proceed.
