Presumably it will be similar to when RCDs came in. New installation, no problem. Complete board change (for other reasons) no problem. What will be a problem will be new circuits e.g. for an extension or that shower squeezed into a corner somewhere. If they have to have AFDD and the existing board won't accept them, that means a board change.
All abord - the gravy train will be departing on 28 March 2022 or should that be 4 days later? ?
