No, you need to be gas registered to cap off any gas pipe. Secondly, you only register heat emitting gas appliances (boilers). Apparently a cooker is not classed as heat emitting. So dont expect hot food.

Hi,

Yes, you need a gas safety certificate to cap off any gas pipe. If anything went wrong with it in the future it would certainly invaildate your house insurance. If the tradesperson you have coming over is a registered with Gas Safety then they will be advising you the same. The worst thing would be to have a gas pipe "capped" and for it to still be leaking. They will more than likely check it themselves once they have carried out the work to ensure they are adhering to the regulations.

You do not NEED a cert, you can ask for one but it not a requirement.
