Hi Peter, welcome to our forum.
If you're thinking about moving to Malta, we have a huge amount of info and lots of people to help with that - so head on over to our Malta forum. Otherwise, we'll do the best we can but we need more input from people who like to give info rather than just take.
If you want to know the tax implications or anything else about Malta then please just ask on our Malta forum.
It seems that Spain is pretty much dead for British expats - so many problems and scams, But each to their own, Maybe it's OK really.
