If you decide to block it up, I would do it in a way that it can easily be reinstated.

Carefully remove the grill from the outside wall. Put a plastic bag in the hole and fill the bag with expanding foam. Once the foam has set, trim back and reattach the grill.

With an extractor hood and a gas cooker/hob, there will be a requirement for a certain amount of free ventilation. The gas fitter should be able to advise.

With gas cookers, unless the room is VERY small, no need for an air vent, as long as there is either a door or window that opens directly to outside air, i.e. not into a conservatory etc. However, there may be good reasons for the vent to be there, don't block it till you have discussed with your Gas Safe engineer at your annual boiler service. As has been suggested, it is possible to block the vent from outside if needed, even by fixing a weather proof board over it, so no need to do it immediately.
