The £1300 AFDD consumer unit

gkenyon:

We are now at a point where the cost-benefit analysis is perhaps moving in favour of fitting them, as I said in my previous e-mail. I agree that, say 15 years ago, my view would have been wholly different, but I'm totally sold on the cost-benefit based solely on the cost of equipment I've had damaged by cloud-cloud strikes alone over the past 20 years, in an urban area (although by the coast). And I know I'm not alone.

I thought that this thread was about AFDD, but as for SPD, I agree. FWIW, I think that the whole business of lightning stroke/strike in BS7671 is far too complicated and I find it difficult to see why a new build would not have SPD. I have never had any damage personally, but when I install a new CU it will have it. It isn't that the benefit has increased, it is that the cost has decreased. ?
