With all the signs of a damn hung parliament, AND the Greek bailout appearing inadequate, after a few days of the euro rate declining I have jumped in and got some from a company I found via
www.moneysavingexpert.com called
TravelFX.com. they are based in Hertfordshire, do not charge commission, free Royal Mail Special Delivery at no cost if over £500s worth, and I got 1.1350 yesterday which was the best rate I could find anywhere. You order your currency with them, and they then send you an email detailing their bank details. You go to your bank website and then pay the bill as normal and it will probably go by Faster payment, so if ordering weekeday AM you will get your currency the next morning, has to be signed for at your address.
