barclays online ?
about £12 per transaction iirc

Assuming you can't do it through the company you work for (who often do it FOC), any of the online share-dealing companies will do it for you. Personally i use T D Waterhouse as they're very professional, but they're all generally within a fiver of each other, fees-wise.
