The way I do it is this:
Get a OKPAY account and got it verified.
Upload GBP to my wallet, via back transfer. (My bank does not charge for this, since it's sent to a UK bank, Barclays)
Then use BTC-e to withdrew the money from OKPAY.
Buy litecoin or bitcoins.

A LOT of HOOPS :-(  

Buy bitcoin(s) at BTC-e and sell at Bitstamp!
