I've just fished out my copy of the 16th edition regs which classifies this
shortcoming as 'requires improvement' but can anyone tell me whether this
classification changed in the 17th edition regs?

Any insight greatly appreciated.

No bonding found does not necessarily mean none present - unless you
know differently? Even if none is present could you install it
yourself using 4mm green-yellow singles or have a local electrician do
the job for you without incurring extensive decor problems?
What it comes down to is how desperate are you to sell.
The 17th edition also provides for omitting supplementary bonding
provided main bonding is present and all bathroom circuits are 30mA
RCD protected. Has your consumer unit RCD provision or could you
replace the light mcb with an RCBO and if no other circuits are
present that should cover the situation. If there are other circuits
RCBO them as well.
