Factsheet relating to the Energy Independence Bill.
Summary
This measure in the Energy Independence Bill introduces new enhanced enforcement and compliance powers to the Energy Act 2011 to strengthen how Minimum Energy Efficiency Standards (MEES) are enforced in the non domestic private rented sector (PRS). Effective enforcement contributes to business bill savings, emissions savings and reduced energy waste already built into the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015.
Why are we legislating?
Issues with enforcement were identified in the 2019 and 2021 consultations[footnote 1] [footnote 2], which set out proposals to strengthen the regime. Subsequent post-implementation evaluations, local authority pilot studies, and ongoing stakeholder engagement have all shown that existing powers are insufficient and that stronger enforcement mechanisms are needed.
This Bill provides the necessary statutory foundations to make MEES deliverable in practice. It provides enforcement authorities with enhanced enforcement and compliance power, including clearer inspection powers, improved data-sharing and reporting arrangements, and the establishment of a compliance database.
What are the government’s objectives with this measure?
Improve local authorities’ ability to enforce the PRS Regulations 2015 to ensure tenants receive the benefits of more energy efficient buildings, including lower bills and reduced carbon emissions. Clear enforcement also creates a level playing field, giving businesses confidence that efficient buildings are not undercut by non-compliant landlords.
Government is also confirming its intention to implement a strengthened non-domestic MEES trajectory requiring an Energy Performance Certificate (EPC) B standard by 2031 for non-domestic private rented buildings in England and Wales over 1,000 square metres. This measure directly supports the objectives of the Bill by ensuring that energy efficiency regulations function as intended, reducing demand on the energy system and protecting businesses from volatile energy prices.
How will this measure deliver the objectives?
The Bill gives local authorities powers to inspect PRS properties and require them to report on enforcement activities to improve transparency. It also creates new powers for the Secretary of State to build a compliance database to assist local authorities identify non-compliance and expands the types of entities that may be appointed to enforce the PRS Regulations.
Without new legislation, enforcement is likely to remain weak, which could undermine overall compliance. Without these enabling powers, reduced compliance would lead to an estimated 26% reduction in the policy’s carbon savings across each carbon budget.
These powers do not impose new standards or costs but ensure existing rules work. By cutting waste, lowering bills, and improving regulatory credibility, it strengthens business confidence, supports growth and energy security.
