As I said before she lives a hundred miles or so from here so will need a proper spark to do the job.
As long as its safe for now thats great.
when she gets the place done up all that stuff will be gone anyway...
With regards to safety of the installation, it would be impossible to offer you a define answer by viewing photos, we can point out what is visually non-compliant or what is potentially unsafe.
I suggest that the first thing your daughter does, is have an "electrical installation condition report (EICR)" done, this will help determine whether this installation is still safe for continued service and flag up most problems.
It's likely that your daughter will end up doing some modernising of the property and new circuits maybe installed, extended or altered. In that event it is very likely that RCD protection will then be required, and from your picture there is no evidence of that being in place at the moment?
So upgrading of the board will be a positive move forward to achieving RCD protection, in most cases prior to having the board changed I would suggest a EICR is made. So having an EICR done now will be helpful with regards to a new CU being installed and determine if the existing installation is safe.
