Thank you @Possum and @arobwk that's really helpful guidance

[Possum]

I would just like to say that I have never moved my polytunnel in the seven years that it has been in existence. I was given the advice about not needing planning permission by one of our neighbours who is a councillor on the local planning committee, so I'm fairly certain that it was right.  Two or three other tunnels have gone up in our village in the last few years and I am not aware of any planning permission being sought. Long may that be the case!
