The TrustMark Consultation for:
TrustMark Licence Plus
For the Great British Insulation Scheme and for TrustMark Strengthening of Financial Protection
Consultation Now Closed
The consultation for the Great British Insulation Scheme and for TrustMark Strengthening of Financial Protection has now closed.
The consultation ran from 4th November and closed on 12th December 2024.
Consultation Background
The Department for Energy Security and Net Zero considered introducing an alternative standard to PAS 2035/PAS 2030 to support a compliance cost proportionate delivery of loft insulation (when delivered as a single measure) and heating controls (when paired with loft insulation), within the Great British Insulation Scheme (GBIS).
The alternative standard the Department considered introducing was a version of the TrustMark Licence Plus (TMLP), originally launched in the Autumn of 2022, with further developed principles for GBIS via an industry Working Group.
The consultation included the proposed design of TMLP for GBIS, proposals for specific financial protection requirements to supplement the proposed streamlined installation process.
The opportunity was taken also to seek views on the wider ambition of strengthening financial protection for the use under government grant-funded and capital schemes and ECO.
Read the Outcome - Published 7th April 2025
The decision as to whether the proposed iteration of TMLP should be utilised for GBIS was a matter for DESNZ. Based on the DESNZ response to its Energy Company Obligation 4 and the Great British Insulation Scheme: Mid-scheme Changes consultation, it has been decided not to proceed with the utilisation of TMLP for GBIS at this time for the reasons laid out in the DESNZ response paper.

Whilst fully respecting and accepting the DESNZ decision, TMLP for GBIS received a wide level of support and some valuable feedback has been presented via the TrustMark consultation, and we will consider how this might be utilized in the future.
On the basis that TMLP for GBIS is not being taken forward at this time, we will not be implementing the proposed changes to the associated financial protection requirements. We remain committed to supporting the appropriate development and strengthening of financial protection mechanisms, we will continue to engage with DESNZ and key stakeholders for this purpose.
Regarding TrustMark’s wider ambition of strengthening financial protection for the use under government grant-funded and capital schemes and ECO as included in our consultation. The proposals were broadly supported but will not be taken forward at this time.
Along with DESNZ, we remain committed to strengthening financial protection and will engage further with the Department and key stakeholders in a bid to establish practicable methodologies so that the overall proposals may be taken forward in the future.
TrustMark is appreciative of the interest the sector took in our consultation and would like to thank those who took the time to respond.
