Well after spending a few more weeks on this pension access issue I have decided on the following. Both my pension companies assure me that if I buy a house in the UK then they will release my pension (provided it's my primary residence, which it will be). Therefore I have enough of a deposit with this and my savings to buy quite a nice house in old Blighty and return to be with family
Last hurdle is to find a teaching job in the UK so I can get a mortgage. Will probably use the supply route to find my way home. When I've bought a house I'll post to show it can hopefully be done
