Does anyone know of any Swiss or French banks that we can approach to lend a mortgage to us to buy a property in th UK? We work in Geneva, have 10% deposit, and have no plans to leave but can't pass up an opportunity that we've come across.

Since the Swiss Franc is unlikely to go down against the pound in the medium term, you can also consider borrowing from the offshore branches of UK banks. Look at the channel islands for instance - RBS etc all have branches here which are set up for UK ex-pats. English speaking staff and UK style mortgages.
