Sounds ideal, BRL.
I'm not sure how aware you are but the approaches to a helipad are just as important (if not more so) than the pad itself. This is particularly pertinent to small single helis, who I imagine might be your most regular visitors.
Have you got the postcode for the pub? Sites like local.live.com or Google Earth/Maps can give us a very good idea of the surroundings of the site without having to visit first. PM it to me if you would prefer.
