It might be worth considering staying in Scotland not just for cost of living/convenience but also the land management/agric approaches will be different here to down in the Home Counties and you will also benefit from the Scottish student funding system..
Generally speaking FE students also get more funding support than HE students and there may be more flexibility in module options at that level too if you're not entirely sure of your direction - so may be worth starting at Elmwood, Oatridge, Barony, North Highland, SAC (Edinburgh/Aberdeen/Ayr campuses) and choose one with options to complete degree level or further training in careers you're interested in..
I was looking at Rural Enterprise at SAC Edinburgh last year but couldn't manage the commute to Edinburgh for 9am lecture starts 3-4 days a week so also watch scheduling of blocks if you want/need to work to support your studies as most folk do
I worked in HE until a few months ago so have a reasonable knowledge of the sector in terms of student funding and support if I can be any help
