New Ikea has charge points. Not free.
They're run by Ecotricity and you pay them - but then IKEA refund you the £6 off your purchase, you just show the ecotricity email receipt.
As for on-street charging, there's a company call Ubitricity who have a system where they can cheaply add charging sockets to lampposts - they use a box as part of the charging cable to authorise and meter what you've used for billing so the stuff in the lamppost can be fairly cheap and simple. A few of the London boroughs have been putting them in, would expect to see more over time.

Is that one of the £1k charging cables dangling from the lampost? Quickest buck anyone can make...
