All installations under government energy efficiency schemes, including the Great British Insulation Scheme, must be carried out by a TrustMark registered business. TrustMark registered installers are required to provide consumers with guarantees from a TrustMark approved guarantee provider. TrustMark have a 3-step dispute resolution process for when things go wrong which includes liaising with the original installer to carry out any required repairs in the first instance. Further information on the steps consumers can take and financial protection for installations can be found on TrustMark’s website here: https://www.trustmark.org.uk/

We recognise the importance of facilitating a competent and robust supply chain. All installations under government energy efficiency schemes, including the Great British Insulation Scheme, must be carried out by a TrustMark registered business. This includes a requirement to meet independent industry standards and to provide a warranty to the householder, in case something goes wrong.

The government recognises the need to reform a fragmented system and will introduce plans to drive-up quality and protect consumers through the Warm Homes Plan.

There is no government financial assistance available to have insulation removed. Any measures fitted under government schemes must be fitted to the highest standards with issues promptly and properly rectified. In any instance where insulation is installed improperly under a government-backed scheme, consumers are entitled to remediation by their installer or, failing that, the guarantee at no cost to the consumer.

Installations of any insulation under current Government schemes must be installed in accordance with the PAS 2030 and PAS 2035 standards.

Officials continue to engage with lenders and the industry to seek a resolution for those facing difficulties.

The insulation, lending, and surveying communities published protocols in March 2023 to support surveyors to assess spray foam, provide reassurance to lenders, and inform consumers. We understand from lenders that in general they follow the advice of surveyors and that most no longer have blanket policies.

The government cannot comment on the decisions made by individual lenders. However, the presence of spray foam should not automatically prevent lending, and decisions should be made on a case-by-case basis following a survey. Whilst one lender may be unable to offer a mortgage to a customer, this does not prevent them from being offered credit elsewhere.

The Department publishes Household Energy Efficiency Statistics. The detailed annual reports provide breakdowns of measures installed under various government support schemes. These date back to 2015 and are available at GOV.UK (https://www.gov.uk/government/collections/household-energy-efficiency-national-statistics).

Warm Homes: Local Grant and Warm Homes: Social Housing Fund schemes began in April 2025. Statistics on the delivery of these schemes will be published in due course.

The Government recognises that the system of quality assurance and consumer redress that we inherited needs reform. This work is already underway, with the existing system being tightened, but we will set out plans for root and branch reform as part of the Warm Homes Plan.

Under the Green Home Grant Voucher Scheme (GHGVS) the previous Government did not specify which types of insulation should be installed in any particular property, only that the installations should be carried out by TrustMark registered installers in accordance with the relevant standards and consumer protection requirements.

If the installation has met the standards required in the GHGVS, we would not expect it to require removal or prevent a mortgage from being issued given the publication of the inspection protocol that surveyors can use to make a judgement.

The Building Safety Regulator published research in March 2024 on the moisture risks from spray foam insulation, which showed that there are many situations where moisture risks are likely to be low, including when insulations are made in line with BS 5250:2021. This research did indicate there is a potential for risks to develop dependent on the specifics of roof assembly, temperature, and humidity conditions.

The research can be found here: https://www.gov.uk/government/publications/moisture-risk-of-spray-foam-insulation-applied-to-timber-sloped-roofs.

All measures installed under government schemes must be installed by TrustMark registered installers and meet the industry standard for installation. If a product has been installed to the standard it should not require removal as a surveyor should be able to use the inspection protocol now available to make an assessment.

Where the measure has not been installed correctly, homeowners should contact their installer or use the TrustMark dispute resolution process to seek redress (https://www.trustmark.org.uk/homeowner/information-guidance/if-things-go-wrong).

Fuel poverty policy is devolved with the Department for Energy Security and Net Zero having responsibility for England. The Government has kickstarted delivery of the Warm Homes Plan, including an initial £1.8 billion to support fuel poverty schemes over the next 3 years.

There are multiple targeted schemes in place to deliver energy efficiency measures, low carbon heating and insulation measures to low income and fuel poor households in England. Schemes include the Energy Company Obligation (ECO), the Great British Insulation Scheme, the Warm Homes: Social Housing Fund (formerly the Social Housing Decarbonisation Fund), and the new Warm Homes: Local Grant.

The Government's review of the 2021 fuel poverty strategy confirms that a new plan is needed to accelerate progress to alleviate fuel poverty. We have therefore consulted on a revised fuel poverty strategy focusing on improving the energy performance of homes, supporting low-income households with energy affordability and protecting them from high prices. The consultation closed on 4 April and we are considering the responses received.

All installations under government scheme, including the Green Homes Grant Scheme must be installed by Trustmark registered installers. If the installation has met the standards required, it is not expected removal will be required.

Where measures have not been installed correctly, homeowners can use the TrustMark dispute resolution process to seek remediation or redress. If the installer is no longer trading, they should contact the guarantee provider.

The Government has also consulted the insulation, lending and surveying communities and published an inspection protocol that surveyors can use to appropriately assess spray foam installations (https://www.property-care.org/resources/spray-foam-insulation-inspections). It is important a surveyor with appropriate knowledge of spray foam and the protocol is used to give an accurate assessment.

The Department publishes annual estimates of the impact of installing insulation measures through government schemes on domestic gas consumption in England and Wales.

As the first step towards the Warm Homes Plan, the Government has committed an initial £3.4 billion over the next 3 years towards heat decarbonisation and household energy efficiency.

Government energy efficiency schemes such as the Energy Company Obligation, Great British Insulation Scheme, Warm Homes: Social Housing Fund and Warm Homes: Local Grant are targeted at low-income households to fund energy efficiency upgrades and low-carbon heating for those eligible.

Further details on the Warm Homes Plan will be set out in due course.

Government energy efficiency schemes such as the Energy Company Obligation, Great British Insulation Scheme, Warm Homes: Social Housing Fund and Warm Homes: Local Grant are targeted at low-income households to tackle fuel poverty.

The Boiler Upgrade Scheme grant provides capital support for property owners to install a low carbon heating system.

Home energy efficiency improvements and upgraded heating systems under these schemes look to reduce carbon emissions, overall energy demand and energy bills for consumers. Further details on the Warm Homes Plan will be set out in due course.

Installations of any insulation under current Government schemes must comply with the PAS 2030 and PAS 2035 standards. In any instance where insulation is installed improperly under these schemes, consumers are entitled to remediation by their installer or, failing that, the guarantee provided.

The TrustMark website contains further guidance on how consumers can complain if things go wrong and the dispute resolution process: https://www.trustmark.org.uk/homeowners/if-things-go-wrong.

Through the Warm Homes Plan, the Government will further drive up the quality of installations and protect consumers.
