There are several questions you need to consider before deciding what is needed:
Now is very much the time to sort things out, as it is before you decorate and it allows you to consider each room's use and what you might need in the way of lighting and electrical power. Doing it later will cost you significantly in decoration costs if nothing else!
If the property is all in PVC wire without signs of damage/degradation then you may not need a rewire as such, but tidying up the CU and making sure all have RCD protection (ideally via RCBO, one RCD per circuit basically) would be worth considering. But if last wired in the 80s or earlier you may well find it short of sockets where you need them, etc.
But depending on the cable condition, and very much on what you actually want in each room, it may well be far, far, better to bite the bullet and get it all rewired to your own plans.
- Is the installation capable of a "satisfactory" EICR?
- Is the installation sufficient for your immediate needs?
- Will it likely be sufficient in 5 years time?
- How tolerant are you to future problems or corrective work?
