Righto,
the CAA rules here are a tad complex.
As a CFI, I conduct BFR's all the time, so need to stay conversant....
In a nutshell..
If you are FIVE years past the EXPIRY date of your last BFR, you need a law exam, appropriate to the licence held IE, PPL or CPL
For example, you do a BFR on 8/2/2005, it is valid until 8/2/2007..
Under the law, you have FIVE years from when your licence was 'current", which would be 8/2/2012 (basically Seven years from date of ISSUE of BFR)
Outside of this period, you need to go resit law
Another problem isa licence issued before about 1992.... they need all the exams, and a re-issue flight test.
You will find CAA helpful if you contact them re this, they will give you all the Gen, by E mail.
Hope this helps!
Cheers...
