the boiler does have a flue to the outside

This is fortunate. Where does the boiler get the combustion air from? If it has a balanced flue, you won't need to provide ventilation for it. Do you have a boiler manual? The information should be in there.

The figures for boilers are 550mm2 for each kW above 5kW. For cookers? I don't know.
