Question: What age should be given for a domestic installation that has 2002 and 2005 PVC cabling throughout, except for 5% older multi-strand PVC cabling to light switches (which is in good condition)?
Answer: Stranded PVC/PVC cable was used up to the 1970s. Larger cable sizes are still available in stranded (10mm and above).
So you should state the age as 40 years originally, with indication of alterations within the last 10 years.
