Peak Acoustics have carried out the first forensic blower door test. Preliminary air-leakage rate recorded was 6.2 air changes/hour measured at 50 Pa. Clearly room for improvement (needs to get down to 1.0), but could have been worse considering the external facing bricks have still to be parge coated. The main culprit did seem to be the cavity wall, so we should see some improvement when that's filled next year.

I couldn't find any details on cavity wall insulation. Did you manage to do one?
