You must know or can find out just what flying is required to keep your Licence itself, valid. At one stage I HAD to fly for six hours, doing six take-offs and landings every six months, to keep my, then, CPL valid.
I was able to fly a Dart Kitten for £1.50/ hour, then, which was sufficient to comply, and no check-ride as it was single seater !
It may be better to do what-ever is required a month early... just in case.
