The Ofcom database of amateur radio call signs as at September 20, 2016 is at

The Reserved classification used in the database is thought to refer
to call signs where the holder has passed away, or the licence has
been voluntarily Cancelled, or is one of the call signs that was
Revoked when Ofcom tested Revocation for the first and so far only
time on a small batch of unvalidated licences in December 2015.
