Well it was in the last budget, so I'm sort of assuming all pension providers will need to abide by the changed rules. Might be wrong. Still wouldn't recommend doing anything before April 20-15 tho, on the face of it would seem to give you a whole lot more options.
The rules all change in April 2015. In theory you could take the whole lot out, tho you'd be liable for tax. Don't do anything before April 2015 would be my advice.
