Problem with the flue on outside wall

Is it a my flue supposed to have a plastic cover over it before the guard? Pretty worried if rain or snow enter through the flue and course damage?

Boiler flues should always be sealed from the outside to stop fumes from getting back into the building and prevent rain water, snow etc. from coming into the property. Cementing around the flue will suffice but modern flues come with a rubber seal for extra protection and to ensure it looks as presentable as possible outside your home.
