Currently have a 4.0mm T&E dedicated spur for the oven, the cable terminates in a 45a double cooker socket - the cooker switch goes no where. At the moment limited to a cooker on a 13amp socket, so if I wanted to get a higher wattage cooker would need to do some tile removal and chasing and add a cooker outlet. Just checking there are no other options, such as a double cooker socket with a flex output?
