Hi. A friend of mine who lives in a 30's semi which has been rewired at
some unknown time in the past ie plastic covered cable, 13A ring main etc
is having a loft extension done. The electrical contractor won't connect
the new wiring in to the existing until he has re-wired the entire
house. When asked why, he just says "it's the new wiring regs".

Same electrician, when asked to move the consumer unit to a place under
the stairs says he can't do it because "the new wiring regs" specify a
minimum height from the floor.

Is there an element of truth in either of these assertions or is the
electrician drumming up business for himself?

TIA
Richard
