'Accidentally' bought the E27 version of the Philips Hue starter kit. Turns out my sockets are all B22. My fault for not checking my light sockets, but I was at my office when I placed the order and I remembered the last bulb I bought was a screw cap...well it turns out that was for the outside light. All the inside ones are B22 Pins.
Amazon aren't being very helpful. They will only Refund the HUE kit or replace it for the same E27 kit. They won't exchange it for the B22 version, because "the price has gone up" (obviously)
Shame. Last time I dealt with their customer service on the phone they were really good.
