One other thought you may wish to bear in mind, is that Houx proper does have electrical hookups. This would leave the possibility of anybody camping down the side of Houx Annexe which is adjacent to Houx to run an electrical extension lead over the road and wall and plug into a Houx outlet.
I appreciate that this may sound initially to be quite hard, but on reflection you would only need about 50 meters of extension lead (good quality outdoor type), a French style camping plug adapter, a cutout protecter and some method of raising the cable above the road for safety. If you ran it straight over the road, I would think you would need quite a lot of protection on it.
Looking at some of your posted pictures Mr Steve Brown, it looks as though you camp in the area I suggested, so would be able to give this a go.
