Scope: This guide covers domestic private rented property in England and Wales. Non-domestic and commercial property has separate MEES rules and timescales. The government has consulted on raising the minimum EPC standard to C in the future — no commencement date has been set. This page reflects the current minimum of E. Always check the latest GOV.UK guidance before relying on any summary.
Last reviewed: June 2026. Primary sources: Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 (MEES), Energy Performance of Buildings (England and Wales) Regulations 2012. TLA is not a legal entity — this page is practical guidance only.
What an EPC Is — and What Landlords Must Know
An Energy Performance Certificate (EPC) rates a property’s energy efficiency on a scale from A (most efficient) to G (least efficient). For domestic properties in the private rented sector covered by MEES, the current minimum rating is E. Letting a covered property below that standard — without a valid registered exemption — is a breach of the regulations.
Exemptions — When You May Be Able to Let Below E
The domestic MEES regulations provide a limited number of exemption routes for landlords who cannot improve a property to E. All valid exemptions must be registered on the PRS Exemptions Register and supported by the required evidence. An unregistered exemption provides no protection against enforcement.
Improving a Property to Reach E
If your property is below E and you need to improve it, start with the EPC recommendation report. This identifies the specific measures the assessor considered and their estimated impact on the rating. Not every measure will be suitable for every property — the recommendation report is the right starting point.
- Loft insulation — where accessible and suitable, often one of the most cost-effective improvements
- Cavity wall insulation — where structurally appropriate and not contraindicated by the wall construction
- Heating system upgrades — boiler replacement, heating controls and thermostat improvements
- Double glazing — targeted window replacement where appropriate to the property
- Low-energy lighting — lower-cost efficiency measure that contributes to the SAP score
- Draught-proofing and floor insulation — smaller but cumulative contributions to the overall rating
Enforcement, Penalties and Risk Management
Local authorities are responsible for enforcement of the domestic MEES regulations. They can investigate suspected breaches, serve compliance notices requesting relevant documents, and impose penalties where landlords have let or continued to let a non-compliant property without a valid registered exemption.
Future Direction — EPC Reform and Proposed C Standard
The government has consulted on raising the minimum EPC standard for the private rented sector to C in the future. No implementation date has been confirmed. The consultation also proposed changes to EPC metrics and the SAP methodology, which may affect how properties are assessed and what counts as a qualifying improvement.
Official Guidance and Reference Points
For the current official framework, use these sources rather than third-party summaries:
Frequently Asked Questions
Do I need a new EPC for every new tenancy?
No. An EPC is valid for 10 years and does not need to be renewed for each new tenancy within that period, provided the certificate is still within its validity window and no significant changes have been made to the property that would affect its energy rating. If you carry out improvements that are likely to change the rating, you may wish to commission a new assessment to benefit from the updated score.
My property is listed — does MEES still apply?
Possibly. The regulations include some exclusions, but listed building status does not automatically exempt a property from all EPC and MEES requirements. The position depends on the specific building, the applicable EPC exemption criteria, and whether an EPC is required at all for that property type. Do not assume exemption without checking the current official guidance and, where appropriate, taking qualified advice for your specific building.
What happens if I let an F or G-rated property without an exemption?
Letting or continuing to let a covered domestic property below the E minimum without a valid registered exemption is a breach of the MEES regulations. The local authority can serve a compliance notice, impose a financial penalty of up to £5,000, and publish details of the non-compliance on a public register. Both the financial and reputational consequences can be significant. Acting proactively — improving the property or registering a valid exemption before re-letting — is the right approach.
I’ve spent £3,500 on improvements but the property is still below E — what now?
If you have carried out all relevant improvement measures up to the £3,500 cost cap (including VAT) and the property still cannot reach E, you may be able to register a cost cap exemption on the PRS Exemptions Register. The exemption must be registered with the required evidence before you let the property. Check the current GOV.UK exemptions register guidance for the precise evidence required — the rules around what counts as a “relevant” improvement and the documentation needed are detailed.
When will the minimum standard rise to C?
No implementation date has been confirmed. The government consulted on raising the standard to C but has not legislated to do so. The current statutory minimum for domestic PRS property remains E. TLA will update this guidance when a firm date or legislative change is confirmed. Landlords with properties currently rated E or D may wish to plan ahead for the possibility of a future increase, but should not treat it as an imminent legal obligation.
