Minimum Energy Efficiency Standards (MEES)

High Level Summary

MEES regulations require that privately rented properties in England and Wales meet minimum energy efficiency standards. Landlords must ensure the property has an EPC rating of E or better.

The Minimum Energy Efficiency Standards (MEES) are a set of regulations introduced by the UK government to improve the energy efficiency of privately rented properties in England and Wales. These standards are part of a broader effort to reduce carbon emissions and enhance the energy performance of the country’s building stock.

MEES regulations stipulate that landlords must ensure their properties meet a minimum Energy Performance Certificate (EPC) rating of E or better before they can be legally let to tenants. Failure to comply with these standards can result in significant penalties, making it crucial for landlords to understand and adhere to the regulations.

Minimum Energy Efficiency Standards Background and Purpose

The MEES regulations were introduced as part of the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, which came into effect on April 1, 2018. The primary goal of MEES is to reduce the carbon footprint of buildings by ensuring that privately rented properties meet minimum energy efficiency standards. This initiative aligns with the UK’s commitment to reducing greenhouse gas emissions and improving energy efficiency across the housing sector.

By setting a minimum EPC rating, MEES aims to reduce the environmental impact of poorly insulated and energy-inefficient properties, which contribute to higher energy consumption and increased greenhouse gas emissions. In addition to environmental benefits, the regulations also aim to protect tenants from high energy bills associated with living in inefficient homes.

EPC Rating Requirement

Under MEES regulations, landlords must ensure that their rental properties have an EPC rating of E or better. The EPC is a certificate that provides information about a property's energy use, typical energy costs, and recommendations for improving energy efficiency. The ratings range from A (most efficient) to G (least efficient). Properties with an F or G rating are considered substandard under MEES and cannot be legally let unless specific exemptions apply.

Applicability and Scope

MEES regulations apply to both domestic and non-domestic (commercial) properties in the private rented sector. The rules cover new tenancies, renewals, and extensions, meaning that landlords must ensure compliance at each of these stages. From April 1, 2020, the regulations were extended to cover all existing tenancies, making it illegal for landlords to continue letting properties with an EPC rating below E.

There are certain exemptions to MEES, including:

  • Cost Exemption: If a landlord can demonstrate that the cost of making energy efficiency improvements would exceed a certain limit, they may be exempt from meeting the minimum standard.
  • Third-Party Consent Exemption: If required improvements cannot be made because of a lack of consent from a third party, such as a freeholder or local authority, the property may be exempt.
  • Property Devaluation Exemption: If the necessary improvements would reduce the property’s value by more than 5%, the landlord may qualify for an exemption.

Exemptions must be registered on the PRS Exemptions Register, and they typically last for five years, after which the landlord must reassess the property’s compliance.

Compliance and Enforcement

Landlords are responsible for ensuring that their properties comply with MEES before entering into new tenancies or renewing existing ones. If a property does not meet the required EPC rating, the landlord currently must undertake energy efficiency improvements, such as installing insulation, upgrading heating systems, or improving windows and doors, to raise the EPC rating to E or above.

Enforcement of MEES is carried out by local authorities, which have the power to impose significant fines on landlords who fail to comply with the regulations. Penalties can range from £10,000 to £150,000, depending on the severity and duration of the non-compliance. Additionally, landlords who are found to be in breach of MEES may be publicly named on a register of non-compliant properties, which can harm their reputation and affect their ability to attract tenants.

Impact on Landlords and Tenants

For landlords, MEES represents both a challenge and an opportunity. On the one hand, the regulations require investment in energy efficiency improvements, which can be costly upfront. On the other hand, improving a property's energy efficiency can enhance its marketability, reduce tenant turnover, and potentially increase rental income.

For tenants, MEES provides greater assurance that the properties they rent will be more energy-efficient, leading to lower energy bills and a more comfortable living environment. The regulations also support the broader goal of reducing the environmental impact of housing in the UK.

Changes To MEES and EPC Requirements

The Labour government announced plans to reintroduce changes to Minimum Energy Efficiency Standards for England and Wales, and have confirmed that rental properties will need an EPC rating of ‘C’ or above by 2030.

Initially, the government suggested that these new regulations would apply to new tenancies starting in 2025 and then extend to all tenancies by 2028.

However, in 2023, under Rishi Sunak these plans were scrapped entirely. However, in August 2024, Labour revisited these plans and confirmed they were reintorducing them, but with an extended timeline.

These proposed changes aimed to improve energy efficiency in homes and contribute to the Government's target of achieving ‘net-zero’ carbon emissions by 2050.

Meaning, as it stands, landlords need to make plans to improve their EPC rating to a C or higher by 2030.

Minimum Energy Efficiency Standards: Conclusion

The Minimum Energy Efficiency Standards (MEES) are part of the UK’s strategy to improve energy efficiency and reduce carbon emissions in the private rented sector. By requiring landlords to achieve an EPC rating of E or better, MEES ensures that rental properties are more energy-efficient, benefiting both the environment and tenants. Landlords must stay informed about these regulations and take the necessary steps to comply, as failure to do so can result in substantial penalties and damage to their reputation.
