I'd got that already telepathically Kingy, you didn't even need to say it. You really do need to come flying with me sometime.
Algirdas, it's 5 hours in 13 months currency, then just before each 13th month is up you trot down to a local club with your logbook, find an R-examiner, and ask them to stamp your logbook. If you aren't a member of the club some charge a few quid, but I think that most people belong to a local club, PFA strut or what-have-you for the social element, even if they do fly from their own strip.
I fly a microlight from a non-school airfield with no CFI. I fly a light aircraft from a (different) non-school airfield with no CFI. That's what I do for both licences (albeit that for the light aircraft they also get £100 out of me every other year for the duty instructional flight as well).
