Four years on the problems, some of them severe, have only been rectified for some of the affected households. Occupants, many elderly and on low incomes, have in some cases reportedly been forced to pay for repairs themselves.
Although the story was well-known to many directly involved with retrofit policy-making, the story had hardly been told outside those circles, but with the help of Preston Council and some of the other people involved, I wrote an article for Passive House Plus, which also features a number of Preston Council’s photographs showing just how extensive the damage was to some of the affected homes.

I did get to visit the area after that article was published, and have since given a couple of talks on what I saw. You can view/download the slides to the one given at an event in April 2018 (organised by Community Energy England and Carbon Co-op): Lessons from Preston – when retrofit goes wrong
