As I've mentioned previously we do a bit of work for insurance companies that put right council/housing association properties after fires/floods etc. (this one was a fire caused by a weed grow). What we usually find in a lot of council properties in our area is the kitchen (if its still there) has been upgraded recently with a new ring and cooker circuit and RCBO's installed in place of the non protected circuits but usually the original consumer unit remains, usually very badly done. this was todays example doing an EICR.
Only a little thing but it took me about two hours to rectify, all because they tried to cram a cooker switch into a 25mm box, couldn't get it back so trimmed the cables down as short as possible. Stuff like this wouldn't normally bother me but we get major grief of the council bods for the slightest thing we do wrong (it might be we put 0.4s in the disconnection box on the cert instead of 5s or fit a 230V 9V backup heat alarm instead of a lithium one) yet the actual dangerous stuff they are totally oblivious to and I come across it time after time.
