The sort of SPD that gets fitted to  consumer unit is not there to save lives.  If lightning strikes the building, the SPD will be gone long before you are.

It is there to clip short duration over-voltages of the kind that sometimes damage cheaply made (but sometimes expensive ) electronics. such spikes and surges arise from inductive loads being switched and perhaps lightning strikes miles away.  Traditional components like motors wire-wound transformers and immersion heaters are not affected by them anyway.

There is no way that its absence is a potential danger to life, unless perhaps you have some sort of life support equipment plugged in and then really a UPS is a better idea.

I think maybe someone wants to bill you for some work, perhaps the inspection fee was a set competitively  low on the assumption of finding something?

Surely there are other things wrong?
