Hi @tals and welcome.
We have recently had a discussion regarding EH and their ‘rules’ and they can control the land which means you cannot take off or land on their property or be in control of while on their property. However, they cannot control the sky above as long as you stay within the drone code of no lower than 150ft/50m and they same distance around the property. Think of it as a sort of 50m bubble around and over the property. @ianinlondon made a great video of flying over and around EH property and the related discussion can be seen here:
