South of France is right, but you need to start using French tout de suite..no matter how bad it feels, just dive in. Agree with all the comments re this place, and commend it...as for taxes, pay someone to help you, but pay 'em...for the QOL and a relaxed outlook, tax avoidance is not a good way to go.
And completely forget the idea of living in the UK...an expensive , dirty and aggressive place to live...despite the very high standards of aviation here...hope I haven't offended anyone, but doubtless some Brit will now weigh in!
