Asked by: Lord Carrington (Crossbench - Excepted Hereditary)
Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what assessment they have made of the impact of minimum energy efficiency standards exemptions relating to leaseholder or third-party consent on progress towards improving energy efficiency in the private rented sector.
Answered by Lord Whitehead - Minister of State (Department for Energy Security and Net Zero)
The impact assessment published alongside the government response to the improving the energy performance of privately rented homes consultation contains information on the expected impact of third party consent exemptions on improving energy efficiency in the private rented sector. The treatment of exemptions in the PRS MEES modelling is found in the attached table.
Table - Treatment of exemptions in the PRS MEES modelling
Exemption | Treatment in modelling |
High-Cost exemption | Modelled: If the cost of making even the cheapest improvement exceeds the cost cap, we do not upgrade a property. |
All Relevant Improvements Made exemption | Modelled: If no relevant improvements can be made then no improvements are made in the modelling. |
Cost Cap exemption | Modelled: Where landlords install measures and hit the cost cap before reaching MEES, the model stops upgrading the property. |
Property Value Adjustment exemption (affordability exemption) | Not modelled: This exemption allows landlords of properties valued below £100,000 to work to a cost cap that is 10% of the property’s value. The NBM does not contain property prices to allow robust modelling of the exemption. |
Solid Wall Insulation (SWI) exemption | Modelled: For simplicity, we assume all landlords who can take advantage of this exemption do so (there may in reality be a small number of landlords who still wish to install SWI). Thus, our modelling results do not include SWI. |
Negative Impacts exemption | Not modelled: We do not account for specific cases where a measure is recommended on an EPC, but determined to negatively impact a property or its value through some other assessment. |
Third-Party Consent exemption | Partially modelled: We do account for in-situ tenants not consenting to improvements at a rate of 10%. However, we do not account for refused consent from other third parties, including superior landlords (freeholders) and local authorities through planning permission processes. |
New landlord exemption | Not modelled: We do not account for property transfers, but given new landlords exemptions only last for 6 months this will not significantly affect modelling results |

Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what preparations they are making to manage any increase in applications for leaseholder and third-party consent exemptions ahead of the proposed changes to the minimum energy efficiency standards; and what assessment they have made of the prevalence of freeholder refusal of consent for energy efficiency improvements.
Answered by Lord Whitehead - Minister of State (Department for Energy Security and Net Zero)
The Department for Energy Security and Net Zero provides an Exemptions Register to enable landlords to register exemptions. The Exemptions Register has sufficient capacity to handle an increase in exemption registrations.
The impact assessment published alongside the government response to the ‘Improving the energy performance of privately rented homes’ consultation contains information on expected prevalence of exemptions, and information on treatment of exemptions in the modelling can be found in the attached table.

Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government how many exemptions have been registered under the minimum energy efficiency standards regulations; and how many officials are responsible for assessing and approving these exemptions.
Answered by Lord Whitehead - Minister of State (Department for Energy Security and Net Zero)
As of the end of January 2026, there were a total of 22,774 exemptions registered on the service, of which 10,519 were still active. Local authorities are the enforcement authority for the regulations, the Department has no role in assessing exemptions.
Asked by: Lord Carrington (Crossbench - Excepted Hereditary)
Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government whether the Department for Energy Security and Net Zero collects and records data on minimum energy efficiency standards exemptions relating to leaseholder or third-party consent.
Answered by Lord Whitehead - Minister of State (Department for Energy Security and Net Zero)
The Department for Energy Security and Net Zero collects and records data on all minimum energy efficiency standards exemptions through the Exemptions Register service.

Question to the Department for Environment, Food and Rural Affairs:
To ask His Majesty's Government what assessment they have made of the requirements for the training and certification of technicians in the use of alternative products during the planned transition away from fluorinated gases.
Answered by Baroness Hayman of Ullock - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
F-gas regulatory changes, such as training and certification, are out of the scope of the hydrofluorocarbon phasedown consultation but their importance in delivery of the phasedown is recognised. The UK Government, in collaboration with the Scottish and Welsh Governments, is committed to further exploring other areas for F-gas reform.

Question to the Department for Environment, Food and Rural Affairs:
To ask His Majesty's Government whether they will consider mandatory training regarding flammable refrigerants as part of the hydrofluorocarbons phasedown.

Answered by Baroness Hayman of Ullock - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
Officials have been in regular contact with sector representatives during the current consultation on reforming the hydrofluorocarbon phasedown and before it. They welcome further discussions as part of ongoing engagement with the sector.

Question to the Department for Environment, Food and Rural Affairs:
To ask His Majesty's Government what steps they are taking to ensure the F gas regulation in Great Britain consultation allows industry sufficient time to carry out safety checks on alternative gases.
Answered by Baroness Hayman of Ullock - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The consultation on reforming the hydrofluorocarbon phasedown seeks views from respondents about potential wider impacts from the proposal. We will take into account responses to those views when making decisions following the consultation.

Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government why they do not plan to achieve the targets set out in the Clean Energy Jobs Plan before the proposed dates for meeting the minimum energy efficiency standards in the private rented sector.
Answered by Lord Wilson of Sedgefield - Lord in Waiting (HM Household) (Whip)
The Clean Energy Jobs Plan sets out the workforce needed to deliver our clean energy ambitions and how the government will work in partnership with industry and trade unions to deliver it. As outlined in the plan, the Government will shortly be bringing forward the Warm Homes Plan. This plan will detail initiatives specifically designed to facilitate growth of the retrofit supply chain.

Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what action they will take to ensure that all properties affected by defects under the Great British Insulation Scheme and the Energy Company Obligation scheme are remediated promptly and safely.
Answered by Lord Wilson of Sedgefield - Lord in Waiting (HM Household) (Whip)
Due to the level of non-compliance in EWI, the Government is offering audits to all households where External Wall Insulation (EWI) was installed under ECO4 or GBIS.
If non-compliance is found, the original installer is responsible for the cost of putting the work right. Should the installer have ceased to trade, the protections under the 25-year guarantee can be invoked.
Checks across all measures under ECO4 and GBIS, will continue to be carried out by TrustMark and certification bodies as part of routine surveillance.
