How should I connect my single oven and separate ceramic hob?

What I would recommend is a registered electrician do the connections for you as would your land lord. P.S. If you feel able to make the necessary alterations to your council houses termination point to the cooker circuit, carry out the required testing and certification for inspection by your local council as it is in fact their property. Then by all means go ahead after all that bit is not rocket science so I'm sure you know how to do those things. Best of luck.
