Easy to use, and it's possible to do as I did and take the currency to the London office. This avoids the postage charge but of course is only a viable option if you live close enought to London to make it economical. The money was paid into my account very promptly and I was kept updated by email. Thoroughly recommended: go through your pockets and cupboards now and get some free money.
