Quite right, stupid question, sorry.
I think I was wondering if you had a standard schedule with tick boxes or something. But in reality I guess houses are all so different that's not realistic.
It is not just the houses... It is the requirements of the occupants that is the key factor for what is needed during a re-wire..
e.g. consider a semi-detached property two identical three-bedroom homes, one half occupied by a young family with three children, eldest aged 11.. the other half occupied by a single widowed 67 year old..
Assuming they are all in good health and will live for another 10+ years.. with no intention of moving house..
But both properties will require a full re-wire within the next 4 or 5 years...
The electrical requirements of the two identical properties will differ significantly!!
Hence there is no such thing as a standard re-wire even for two very similar properties..
In my opinion there is no point adding wiring that you will never use or need....
just in case you think it may help an unknown person who may or may not ever purchase your property at a later date!
Just as there is no need buying a seven seater car if you only need four seats...
But you think it may be easier to re-sell a seven seater when you finally do want to get a new car!
