What, exactly, does "MH access" mean

It's probably a height restriction?

I would assume there is not restricted access for motor caravans if it s in the club handbook ie no height barriers

There are one or two that say they have height restrictions, one that says "no MH access" and loads that don't say anything at all.  Surely someone must have used some set of criteria for making the assessment.

Perhaps they are repeating information from Motorhome Parking or similar. LINK

Must admit that my first thought related to height restrictions.  Can't get at the handbook at the moment as it's in the MH; is this relating purely to supermarkets?  I'd have thought supermarkets were all accessible to MHs, apart from some of the smaller ones perhaps in town centres.  No idea what criteria have been used for it.

Perhaps an idea to have a look at the one which said "no MH access" on Google Earth, maybe that will give a clue.

I can't see my handbook just now but like InaD I'd agree that most supermarkets have M/H access with one or two exceptions. I'm not sure why the Club are including these details as there are likely to be other shopping options in any given area.

I’ve not yet met a supermarket that wasn’t accessible with a MH, or accessible by whitevanman, or an ambulance, or a fire engine……

I looked on MHP (posted above) it mentioned Asda has one or two car parks with height restrictions. Our nearest Tesco has a multi-storey car park with limited open air parking but other supermarkets are available. 

Just had a look at Cirencester. Waitrose is the closest supmarket, which is says is MH accessible. There are certainly no height barriers but the car park is not huge and is fairly tight in places. It would depend on the size of the MH, however personally I think a better suggestion would have been the Tesco, a mile or so further away but with a huge car park, which always seems to have plenty of room. The Tesco is not mentioned.

Our local ASDA has height barriers which are only used on occasion
