Thanks for the responses.
On broadband, this would be a deal breaker if no good mobile service is available either. I really would need either solid broadband or good 4G (doesn't have to be blazing fast, but reliable). I was actually thinking mobile coverage likely would be the better option in some places and avoids having to pay for connection. Failing both of those Starlink may become an option soon.
In terms of grid, so long as I have internet I think I could likely make things work somehow. I have some experience with solar and battery setups and would enjoy giving that a go. Gas I would rather avoid, no particular reason really but one less thing to think about. Water and sewage would definitely be nice. If it was a hut I was building then compost toilet would be okay. If it was £100k plot and house, then definitely I would be wanting full grid electricity and water.
Yes, a big red dwarf fan - or at least was.
https://www.thousandhuts.org/ is a good site and definitely made me interested in hutting. The big problem and turn off is that it simply is not easy to get involved. If I could get a cheap bit of land and build my hut I would be happy. But the fact you still need planning and that your time spent in it is limited really puts me off. If I am spending £100k to get land for a hut, I feel that is rather a waste when I could buy different land with a view to building a full home. That and to be honest i am not interested in group hutting, which seems to be more common. If not for the uncertainly over planning what I likely would prefer is to buy some agricultural or woodland and build a hut, leaving house building for a bit into the future.
In terms of viewing places, I would definitely be up for it. I just want to have a decent idea on whether its worth the trip first. The plots near Loch Tay for example, I would have visited but contacting the planning department made me none the wiser when it came to suitability (assume not suitable otherwise it would be sold as such). One thing in particular regarding the plots was whether a business + house on the land would be seen as a positive or a negative. Also whether projects like rewilding or planting tress would be favourable or against (somewhat in conflict with having a house).
Thanks
