People quickly forget that it costs about £2,000 to simply move house withing the uk and that's if you are renting, probably costs ten times that if you are buying. A whole new life on thecother is going to take most people at least two years to recover from financially.
All I can compare is our circumstances and my husband was job hunting for 3.5 years in the UK and has a role in Perth within 3 weeks working a very normal 9-5 for 85,000 so that will do for now.
