Yes agree with Artel just come back from Britany and Normandy four sites all had hose lock fittings and all had uk spec 240v hook up but I dont think that is as common as the water connection

Don't forget to leave a review of the French and other European campsites you have visited!
In Spain the water tap was threaded 1/2" bsp which is one size smaller than ours(3/4 bsp). If you buy one of those brass adapter kits they sell in Wilkinsons they're both in that, along with the hose lock snap on thing. Bit dearer than plastic versions but much better.
