Just rewired a VIR house and the cable under the floor was fine.... Made in Lydbrook in the Forest of Dean :smug: Didnt appear to have degraded at all, however where it has seen the light of day, or been warmed .... Different story.
Any damage to the old VIR/TRS is generally limited to the connected ends, especially at incandescent enclosed light fittings and accessories, or at outlet points that have been carrying current at or over it's CCC for many years. I've stated before, that i used the TRS cable i pulled out of my parents house, to wire the sockets in my fathers garage, and it's probably still there to this day. It was in pristine condition, and just the job for wiring a freezing cold garage... lol!!
