What dates did they die? It seems that Findmypast have started matching up records from the 1939 register with the death index (which goes up to 2007), so if your father and aunt died before 2007 there's a chance that their records have been opened since you last searched, or will be opened soon.
FindMyPast
claims to have deaths up to 2007, but I have not found this to be the case. My uncle died in Jan 2007 and my father in March 2007 and neither are listed on FindMyPast death index so neither have been opened on the 1939 register.
