I had assumed it was a cooker radial circuit the old cooker plugged into but it turns out it is actually just on the downstairs ring main.
The electrical part of the cooker died a few months back and my landlord has finally bought a new one however he has bought a double oven with a gas hob with a draw according to the manual of 4.50 - 4.8KW. Our old cooker was rated at 3KW with a gas hob and it just had a standard 13 amp socket which plugged into the wall near the cooker.
