Parking for high vehicles (campervan / motorhome)

I don't know whether this would be helpful https://park4night.com/en/search It is mainly for people wishing to park overnight but I assume the same places might be available during the day? If I am going to something like a NT property I usually email ahead just to check. There are various online resources like Google Earth and Street View that can give a pretty good impression of whether there is room to park, although what it won't tell you is whether you are allowed to park there!

A&MW. Did you not Google it?  There is also  www.park-my-motorhome.co.uk

Campercontact might be a useful app too.

Some councils have information on their websites about which car parks have height barriers, and where they cater for motorhomes. 
Some car parks allow you to pay for two parking places where you need to take more than one space. But this becoming more difficult to do. 
Street side car parking can be easier in some cases, especially where there are no bay markings.

It is the big down side of motorhoming in the uk.
