Hi Smallman,
I presume your refer to Barclays Wealth International?
I opened a euro account with them and it was straight forward really - send across application form and certified passport, utility bill etc. Account opened with no annual fee once you hold the equivalent of £10,000 on desposit. Small interest rate of about 1% applies.
As far as Im aware if you open an account with their London Knightsbridge branch, then it is guaranteed by the UK Compensation scheme for up to £85,000. If anyone believes this is otherwise, please feel free to correct me on this.....
I have yet to get round to transfer my savings here by the way as considering other options too before committing.
