I never put a cooker switch with onboard socket outlet in. To me its a throwback to the old days of yore when people never had enough sockets (example one on ground floor and one on first floor) and ho if we adding a lecky cooker circuit we will throw i  that extra socket outlet. They were intended to be for occaional use of kettle but often get used for a washer or drier etc, not good. If you need extra sockets put a proper un in. Of course if youare replacing an existing damaged unit then ok but if its not RCD protected already then advise customer. I cant think of many times i have been persuaded thatsuch a socket will neverbe used on outdoor extension leads thrown thru a window.
