Recommendation (the committee's words)
The National Audit Office also reported that some company directors are closing and restarting their businesses to avoid remediation responsibilities.40 TrustMark told us it has developed a watchlist and can stop a new business operating until it has fixed the faulty work for which its directors were responsible under the previous business. TrustMark told us it was not working directly with Companies House or The Insolvency Service on these matters but, upon our prompting, accepted that it should do.41

Government response
The government responded to the whole report on 7 April 2026 (deadline 23 March 2026).
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with most of the Committee's recommendations, but disagrees with the recommendation to halt wall insulation installation without independent supervision and with the recommendation to refer fraud to the Serious Fraud Office.
- On wall insulation, it disagrees with the recommendation, noting that every household with external wall insulation under ECO4 and GBIS "is being and will be offered an on-site audit", subject to the householder accepting; internal wall insulation concerns are triaged and referred for audit where they meet "the threshold of risk factors".
- It agrees on the find-and-fix programme: TrustMark "currently intend" it to complete by May 2027, though the department states it is "unlikely" to deliver on a "significantly shorter timescale". It will update the Committee in writing every six months, first in June 2026.
- It disagrees with referring fraud across ECO to the Serious Fraud Office, stating that this "relates to an existing ongoing responsibility of the regulator", Ofgem, which can and does make referrals where appropriate.
- It agrees to publish an annual report to Parliament on retrofit schemes, with the first publication "before Autumn 2027", and "intends to consult" on the design of a reformed consumer protection system during summer 2026.
