An EPC rates a property's energy efficiency from A (best) to G (worst). It is produced by an accredited domestic energy assessor, is valid for 10 years, and must be provided to a prospective tenant before they view the property. The certificate must also be included in any rental advertisement.
Since 1 April 2020 all privately rented properties in England and Wales — regardless of when the tenancy was granted — must meet the minimum E rating. Letting an F or G rated property without a valid registered exemption is a civil breach carrying penalties of up to £10,000 per property.
What are the Minimum Energy Efficiency Standards (MEES)?
The Energy Efficiency (Private Rented Property)(England and Wales) Regulations 2015 require all domestic private rented properties to reach a minimum EPC rating of E before being let or renewed. Key milestones:
- From 1 April 2018: New tenancies must be E or above
- From 1 April 2019: Renewals and rollovers must be E or above
- From 1 April 2020: All existing private rented properties must be E or above (subject to exemptions)
- Expected from 2030: EPC C required for new tenancies (not yet law as of May 2026)
- Expected from 2033: EPC C required for all tenancies (not yet law)
MEES exemptions — when you can still let below E
If your property cannot reach an E rating cost-effectively, you can register an exemption on the PRS Exemptions Register (available via the gov.uk portal). Exemptions last 5 years and are property-specific. Valid grounds include:
- High cost exemption: All relevant improvements cost more than £3,500 including VAT
- All improvements made: You have completed every recommended improvement but the rating remains below E
- Wall insulation exemption: An expert confirms insulation would damage the property's structure
- Third-party consent refused: Required consent (freeholder, planning authority) was denied or subject to unreasonable conditions
- New landlord exemption: 6-month grace period when you became landlord by inheritance, court order, or repossession
EPC validity and re-assessment
An EPC is valid for 10 years from the date of assessment. You do not need to commission a new one unless:
- The current certificate has expired (check the EPC Register at gov.uk/find-energy-certificate)
- The property has been significantly altered — new roof, extension, new heating system — which may change the rating
- You want to demonstrate improvements have raised the rating above E (or towards C) for marketing or compliance purposes
EPC C target — what landlords should do now
The government has signalled EPC C will be required for new tenancies from 2030 and all tenancies from 2033, though no regulations are yet in force. To prepare:
- Commission a new EPC assessment to identify the cheapest improvement path to C
- Prioritise fabric-first improvements: loft insulation, cavity wall insulation, floor insulation, and draught-proofing
- Investigate eligibility for the Great British Insulation Scheme (GBIS) or ECO4 funding
- Budget for boiler replacements or heat pump installations — these are significant capital expenditures
- Discuss planned works with your mortgage lender if your buy-to-let product has green conditions
Penalties for non-compliance
Local authorities are responsible for enforcing MEES. Penalties are applied per property per breach period:
- Up to 3 months in breach: penalty of up to £5,000
- Over 3 months in breach: penalty of up to £10,000
- Publication: the breach may be recorded on the PRS Exemptions Register public record
- Possession impact: non-compliance is a potential tenant defence against possession, indicating broader landlord non-compliance
Frequently asked questions
What is the minimum EPC rating for a rental property in England?+
The minimum EPC rating for a privately rented property in England and Wales is E. Properties rated F or G cannot be legally let unless a valid exemption is registered on the PRS Exemptions Register. The exemption must be registered before the tenancy starts or continues.
When does the EPC C requirement for landlords come into force?+
As of May 2026, no EPC C requirement is in force. The government has indicated EPC C will be required for new tenancies from 2030 and for all tenancies from 2033, but no regulations have been laid. The current legal minimum remains E.
How long is an EPC valid for a rental property?+
An EPC is valid for 10 years from the date of assessment. You can use the same EPC for multiple tenancy renewals within that period, provided the property has not been materially altered. Check expiry dates on the national EPC Register at gov.uk/find-energy-certificate.
Can I let a property with an F or G EPC rating?+
Only if you have a valid registered exemption on the PRS Exemptions Register. You cannot simply claim an exemption — you must register it before the tenancy begins. Valid exemptions include the high cost exemption (improvements cost more than £3,500), all improvements made, third-party consent refused, and others.
What is the penalty for letting a property below the minimum EPC rating?+
Local authorities can impose financial penalties of up to £5,000 for breaches up to 3 months, rising to £10,000 for breaches over 3 months. The breach may also be recorded publicly and can complicate possession proceedings.
