Chelsea recently found themselves to be highest in altitude, but missed off the NPC 150m, UBSS 155m, Cerberus 205m, MNRC & Craven 230m, Shepton & Wessex 255m, the Dudley's windmill also has accommodation, but I'm not sure exactly where it is (& are we missing any others ?)...
The Welsh huts would also seem to average the highest at 285m, with Peak next 272, Dales 234 & Mendip 230.
