hello confusedozzie337,
where in Somerset are you looking to relocate to? We moved to Taunton in Somerset with my Aussie husband,( I'm British) work prospects are ok in terms of finding placements however pay is a lot less than Aus. It's all relative though really as some aspects of UK living can be cheaper.
Life is great in the UK, if you are willing and able to make the most of it. I won't lie it is a hard transition coming from Aus but you will settle into it, the weather can be a bit depressing but it is nice having the 4 seasons, and Europe on the doorstep makes it all worthwhile!
let me know if you do end up in the Somerset area, would be good to meet up, there is a distinct lack of Aussies in the regional areas of the UK so would be good to get the numbers going!
Hope you you can make your decision easily enough.
