What is causing a banging/knocking noise on inside wall when it's windy?

Hi, hoping someone can help as this problem is driving me mad! Every time it's windy there is a banging/knocking noise, which seems loudest with my ear pressed up against the inside wall which separates me and my neighbour (small semi-detached, 1920s build). It can be heard downstairs as well but seems loudest in the main bedroom upstairs, which the chimney breast goes through. I've tried googling and have seen suggestions of a loose chimney pot but I've been outside with binoculars and can't see any movement, and I had the flaunching re-done when I moved in last March. There are two aerials attached to the chimney, one in use and one old, but neither seem to be moving to an extent which would cause knocking. I have a gas fire in the living room which has been tested fine. There are several wires running across the roof but again these don't appear to be moving and I wouldn't have thought they would cause such a noise. The noise itself isn't constant, and isn't consistent (difference in volume, tone) but it's unbelievably frustrating and has been preventing me from sleeping. Any suggestions as to what might be causing this and what I could do to address the problem would be massively appreciated.
