EPC Minimum Standards: Enforcing Energy Efficiency in PRS

The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 established Minimum Energy Efficiency Standards (MEES) for the private rented sector. Since 1 April 2020, it has been unlawful for a landlord to continue to let a property with an EPC rating of F or G (the two lowest bands) unless a valid exemption is registered. The regulations are enforced by local authority trading standards teams, though in practice many councils coordinate enforcement between trading standards and housing enforcement teams. The government has indicated plans to raise the minimum standard to EPC C by 2030 for new tenancies, with all tenancies covered by 2033, though the exact timelines and exemption framework for the higher standard are subject to ongoing consultation.

The EPC register is publicly accessible and provides data on every property that has been assessed. Councils can download bulk EPC data for their area from the MHCLG Open Data portal, which includes the property address, current EPC rating, certificate date, and key building characteristics. By filtering for properties rated F or G and cross-referencing against known PRS properties (from council tax data, licensing registers, or the PRS Database), enforcement teams can identify properties that may be in breach of MEES. Not all F and G rated properties are in breach because some may have valid exemptions registered on the PRS Exemptions Register, operated by the National Trading Standards Estate and Letting Agency Team. Officers should check the exemptions register before initiating enforcement action. Properties where the EPC has expired (EPCs are valid for 10 years) should be flagged for a new assessment, as the building's energy performance may have changed.

Landlords can register exemptions from MEES in several circumstances. The 'all improvements made' exemption applies where the landlord has carried out all relevant energy efficiency improvements identified in a Green Deal assessment, a recommendation report, or an EPC, and the property still does not reach the minimum E rating. The 'cost cap' exemption applies where the cost of making energy efficiency improvements exceeds the applicable cost cap (currently £3,500 including VAT). The 'wall insulation' exemption covers situations where insulation cannot be installed due to a negative impact on the fabric or structure of the property. The 'consent' exemption applies where necessary third-party consent (from a tenant, freeholder, or planning authority) has been sought and refused. Exemptions are valid for 5 years and must be re-registered after expiry. Officers should verify that registered exemptions are genuine and that the supporting evidence (quotes, assessment reports, refusal letters) meets the regulatory requirements. Fraudulent exemption registrations should be challenged and may constitute an additional offence.

Penalties for MEES breaches depend on the duration and nature of the non-compliance. For letting a non-compliant property for less than 3 months, the penalty is £2,000. For continued letting beyond 3 months, the penalty rises to £4,000. These amounts apply per property. For repeat breaches, penalties can be imposed again. The total penalty for a single property over a 12-month period is capped at £5,000. The enforcement process involves serving a compliance notice requiring the landlord to bring the property up to the minimum standard within a specified timescale, followed by a penalty notice if compliance is not achieved. Landlords can request a review of the penalty and, if unsatisfied, appeal to the First-tier Tribunal. Penalty income is retained by the local authority. Given the relatively modest penalty levels for MEES compared to other housing offences, enforcement should also consider improvement notices under the Housing Act 2004 where poor energy efficiency creates a Category 1 or Category 2 excess cold hazard.

The government's commitment to raising the minimum standard to EPC C will significantly increase the number of properties in breach of MEES. Currently, approximately 55% of PRS properties are rated D or below, meaning a move to a C minimum would affect over 2 million properties. Councils should begin preparing now by mapping their PRS stock against EPC ratings, identifying the scale of the enforcement challenge, and engaging with landlords about improvement opportunities. Government-funded schemes such as the Great British Insulation Scheme and the Social Housing Decarbonisation Fund (some elements of which may benefit PRS tenants through area-based approaches) can support landlords in meeting higher standards. Enforcement teams should build relationships with local energy efficiency installers and advice services to signpost landlords to support. Proactive engagement now will reduce the enforcement burden when higher standards come into force.
