The QoL adjustments seem less granular than needed in the UK. "Everywhere else in England" covers a wide range of living conditions/costs. Areas like York & Harrogate are far more expensive to live in than the not-all-that-far-away Grimsby & Hull, to give one of many possible examples. If you are going to change what you pay geographically, I would suggest you need more local variance to do it properly.
