i've been asked to swap a coin operated electric meter and i'm wandering if i'm allowed to do it (ie does it need to be certified) the building has one supply/main meter then each flatlet has its own coin meter which can be individually isolated. its a straight swap - like for like so i dont see any reason why it would need a cert but i'd like to be certain as i never touch what i'm not allowed to.
