If the project
I think that Wickes may still have some of their 100m drums of 2.5 T+E cable that is date stamped '2004'. Something that might persuade an inspection that the work started in 2004.
I expect you'd have a harder job if the cable is dated stamped 2005!
All my kitchen wiring is either undated or 2004 vintage. I have simply updated the sockets ;-)
My local wholesaler has said that they can get me 2004 armoured cable in the pre-harmonisation colours for the end of garden woodstore light. Very accomodating.
