I congratulate my hon. Friend Holly Lynch not only on securing this important debate but on making the detailed case that needs to be made about his scandal. The contributions of hon. Members from across the Chamber have added to her exemplary presentation, and have underlined the urgent need to do something about the issue. My hon. Friends the Members for Blackburn (Kate Hollern) and for Bradford East (Imran Hussain) and the hon. Members for Tiverton and Honiton (Richard Foord) and for Strangford (Jim Shannon) all made first-class contributions to the debate.

Cavity wall insulation has played, and will continue to play, a tremendous role in keeping people’s homes warm, reducing bills, fighting fuel poverty and uprating homes so that they are fit for a low-carbon future. Indeed, the vast majority of cavity wall insulations work perfectly well and do a good job for the homes where they are fitted. Of course, cavity wall insulations need to be done with the right materials, by the right people, in the right places and according to the right standards. I regret to say that there are circumstances—rather more in the early days than now—where those criteria were not adhered to, and problems arose with properties in which cavity wall insulation had been placed.
