I moved out to a village a number of years ago, and I am very happy here. That being said I think there are a couple of points to take into account. Firstly, villages like towns have different personalities, and some can be quite unfriendly, so do your normal house moving due diligence on local media, walk round at different times of day and one I always find useful, a couple of visits to the pub if there is one.
Typically in village life everyone will know everything about you. This can be very supportive at times of need. When I was looking after my late FIL, I got lots of help from people I did not know. Conversely, there will be times when it might feel intrusive.
The isolation is a positive and a negative. I like the quietness and open spaces, the nature and the other things that come with village life, but be really honest with yourself if this is for you. Some people really do not like it. I have access to some great meat and vegetables here, but the best restaurants, nightlife etc are a good distance away. I do a number of overnight stays in London, so this is fine for me but I would consider if this is doable.
Think about the sighting of the village you are moving to. What are transport links like? For us our village is ten miles from the nearest (Small) city, which is quite good but does mean as teens the taxi of mom and dad was very active indeed.
For a short while our teens hated living here... but now love it again, so this is also worth considering.
