Correct.
Not so long ago when we moved into a new (to us) house in Onchan, the wife's uncle (who was a retired site manager for Costains the builders across)who used to stay with us to watch the bike racing said, "Aye very nice house our Andrew but I think you're going to have problems with damp...... where's the air bricks?" They were covered up with tarmac by the path that ran around the perimeter of the property. Needless to say they were cleared and we had very little in the way of condensation from that point on.
