I don't know your circumstances in UK, none of us do, but if my husband was earning more there, than he is here, I would stay there in UK and maybe buy a holiday home in the sun.

Tax aspect, OK, so you earn effectively more here. One third? not sure what one had to pay in UK at the moment, but I guess NI stamp comes off as well.

Salary and housing sounds ok. Not sure if you have kiddies - schools cost.

Be good if you could let out your home in UK whilst here too!
