I have a feeling although my circumstances are just about perfect I think they will take issue with me still having ceramic fuses and not a consumer unit. The reason I still have them is that so far there has been no advantage to my having a consumer unit. It would not be more efficient and in the last 25 years the only time a fuse has blown is when an old style(now banned) bulb has blown and shorted. Plus I could put one in myself but I am not allowed to. If I hadn’t been here so long and could blame the previous owner I would just change it myself. I am not paying £400 to have one put in when the unit itself is only £70 and I could fit it if not for red tape.
