air brick removal

Hi,
I have an air brick situated immediately above the front door (1970s cavity wall insulated house). I suppose it's there to provide ventilation for people inside, rather than any of the structure. I have installed whole house mechanical ventilation, so would like to block at least the internal part of the airbrick. Is there any reason I shouldn't do this. I plan to leave the external half as it is in case it vents the cavity.

thanks,

Do you have any open flued gas appliances ie back boiler etc?

no, the heating system has been replaced by a modern combi boiler. I think it used to be some kind of hot air system, heated by gas. It used to be in a cupboard near the front door.

In that case it shouldn't be a problem
