Thank you for sharing this. I looked at English Heritage and it says
"We take equality very seriously, and provide free site access for assisting companions of a disabled Member or visitor. We recognise these companions are key to making access possible, as well as creating an enriched and memorable experience.
We don't ask for any proof of disability, and the companion doesn't have to be a registered carer, nor do they have to be the same person each time you visit.
If you'd like a letter of authority giving your assisting companions free access, please contact us on 0370 333 1182."
