Yes an electrical W.O.F. for existing houses would have to be properly policed. I do share everyone elses opinion that this would never happen. Kenbo is right in saying that if we can't even get a system right for new buildings then we've got no chance of organising a decent system for existing buildings.

As usual our government & local councils will turn a good idea into an inefficient, corrupt, revenue grabber that achieves nothing.

I suppose its a big ask expecting government bodies to employ enough people qualified & experienced enough to judge wether a building is electrically safe or not.
