These new requirements will mean that any house sold will have to have a
certificate issued to the vendor before anyone will be allowed to pass the
property on as being in a safe, as possible, condition when it was sold. So
any additional work that you've carried out in the house will then be tested
and documented and will show all the variations which you've carried out and
are not documented on a previously issued certificate that was given to you
when you bought the house.

But the certificates I've seen don't detail the wiring in terms of a
wiring diagram anyway so you can't tell whether anything has been
added from the certificate.
