You can earn £35k in Exeter but there’s not a huge choice of work. If you were committing to moving from a different part of the country it’s risky, and gets more risky the further south you go. Maybe a backup plan if things go wrong?
I would suggest living in Taunton and work in Bridgwater at the Morrisons RDC, its run by Wincanton. Bristol is a great choice for work and as has been said before, you could live in south wales and commute, although I have no idea of house prices or quality of life around Newport.
I didn’t take to Somerset personally, Devon is nicer. I lived in Clevedon, North Somerset, for a while which is just weird in a way you can’t put your finger on. Bridgwater is full of inbreds. I found North Devon to be a category of it’s own due to it’s geographical location, a bit insular if that’s the right word. Don’t be tempted to move somewhere just because it has lovely beaches.
