Non EHU & enforced EHU

The Sandringham National was EHU take it or leave it, I have spoken with several of my centre ralliers, and about 50% said they would have liked a choice, as most ralliers are geared up for off grid, many vans now come with solar panels, I for one would have preferred non EHU, certainly didn't use £ 5 worth of electric a day with only a 6 amp supply.

There were certainly not enough pitches this year, I heard several people complaining before and after the rally that they could not get a place, and walking around the site there appeared to be many unsused area, so I can only assume that the rally was setup around the available electric points and generators etc.

Could someone from the club confirm if all future nationals are going to be EHU only, and why this will be so, I personally consider this a bacwards step.
