I hate to join in Hamish - but why are you bothering to keep the licence if you only put in 12 hours in 2 years? It cannot be worth the trouble.
IIRC you can let the whole thing lapse for up to 5 years and re-validate with a flight test so why waste a couple of days a year going around the circuit?
It has to be said that with low total hours, flying infrequently means you are not learning much, you are simply trying to catch up with where you were........
