I'm hoping i'm reading in to your post wrongly but am i to understand that you've changed a consumer unit and not installed bonding? That's just how it sounds and can't figure out if there was no CPC and class 1 fittings and you left it this way or not?
IMO, if there is class 1 fittings and no CPC then class 2 fittings can be used to replace the existing fittings to comply with the regs. A warning notice must then be attached to the consumer unit stating that no CPC is present on circuits x,y and z and that class 1 fittings must not be used. A 30mA RCD is also recommended for additional protection but that will be fitted regardless as per the 17th requirements for cables buried in walls. Alternatively the whole lighting circuit should be stripped out and rewired, it would be 40 odd years old after all!
The key sentence is "As the house didn't have any main bonding or equipotential bonding before I started, the conclusion was that the site was safer than before."
Didn't, meaning it didn't have before, obviously now it does!
