If you look at your the oven and grill bit will probably plug into a normal socket, you need to look and see if it is. The hob bit if your lucky will have a rubber pipe coming from it that plugs into a special gas connector. You are allowed to undo these as they are self sealing on both the plug and socket part.

Ring me its easier to explain. Has yours got a shared oven and grill or is it a double oven with a grill in the top oven?

Shared single oven and gril are naff, you cant oven and grill at the same time.
