Regular at the Castle in N. London. Relatively little done outside: sports climbs at Portland and El Chorro (southern Spain) and some easy trad climbs in the lakes, peak district and north Wales (mostly seconding).
This is now very out of date. More sport climbing done and some trad - highlight being multi pitch in Taffrout, Morocco. Sport climbing in New Zealand. Trad climbing in Llanberris. Sport climbing in Tonsai.
Equally happy stomping around the hills as climbing on them.
