I'm afraid that to a fx broker that wouldn't be considered a large amount - it's retail not commercial. You are probably best going through your own bank - they should be able to offer you a rate with a smaller spread than the tourist rate, even though you won't get proper money market rates on a one off deal of that size
Hi franke. We have done this and used a company called FX Solutions. It is free of charge for amounts over £20,000. Their website is www.fxsolutions.co.uk and their telephone number is 01689 601111. It is very easy to do and quite painless!
Yes you're right Prufrock - there is the possibility of losing interest. We always did it by cheque and it took about 5 days or, of course, we could have done it by bankers draft, but the Bank charge £20 for that! I have to say, the rate FX offered was way better than the Bank so definitely worth it!
