Read notice on door stating due to increase in electricity, pitch was now going to be £22 & not £20 as advertised at time of booking, which was understandable. Only using site for 1 night to catch ferry next day. We arrived at 6pm & left at 10 am. Our electricity use comprised of 4 half kettles water for tea , small oil heater & minimal use first thing in morning of a small air blower which we never used constantly & tv, which ran for approx 4 hrs. On leaving the owner checked electric meter which we didn’t understand the reading process or new we even had one, told us we had 10 units included in pitch & we had extra £4 to pay which I was surprised at for such a short time. But how is this worked & what cost per unit is he charging because we really only used a small amount of electricity in that short time. So beware when you hook up there is possibility of extra to pay without you being informed beforehand.
