Id say it comes down to the way cave diving in Briton is largely different from that of mainland Europe. So even on site the British cave divers would see the approach as different to the Europeans
In Briton cave diving is largely done to move between flooded sections of dry cave, so most cave divers are dry cavers first, and diving is just used to bypass sumps.
Also most British cave diving is done solo (so without a buddy that most systems recommend.) in quite tight conditions.
Caves in mainland Europe tend to be larger and the diving philosophy is different. There you will find team diving prevalent.
