Hi, As part of a kitchen renovation, a new vertical radiator was to replace an old regular one. Only one of the vertical pipes to the floor was replaced (the one on the right in the pictures, from a white-covered existing one to a copper one) while the other one wasn't (I presume so it was less work?), then both pipes covered with not-very-impressive plastic covers. Can you tell me if this is industry standard/normal? I would have expected both pipes to be replaced for new ones, but you know better. Also, the gas hob was replaced with an induction one (thus, gas supply capped off): should I've been issued any gas safe certificate? Even if not compulsory, can/should I request one? Thanks!
