The story of the failed retrofits in Preston, along with similar issues faced in Blackpool and – this time, with cavity insulation – in Leeds, were covered in an item by Zoe Conway on the BBC Radio 4 Today programme. I helped Zoe with some background, but she did a lot of work visiting the sites and interviewing occupants, and I think this was a pretty fair account.
The report can be heard here, until the beginning of December: https://www.bbc.co.uk/sounds/play/m0001282 -starts at approx 1hr 33m.
The Radio 4 item was also picked up by Mail Online later that day.
