The Minimum Energy Efficiency Standards prohibit letting residential properties in England and Wales rated below EPC band E. Since April 2020, this rule applies to all private tenancies, not just new ones. Fines reach £30,000 per property. A proposed upgrade to band C by 2028–2030 makes proactive compliance essential.
What MEES currently requires
The rules are specific: you cannot lawfully let a residential property in England or Wales with an EPC rating below E. "Letting" includes granting a new tenancy, renewing an existing fixed term, and continuing an existing periodic tenancy. The current standard has applied since:
- 1 April 2018, new tenancies and renewals
- 1 April 2020, all tenancies, including existing periodic agreements
If you have a long-standing tenant who moved in before 2018, MEES has still applied to that tenancy since April 2020. A property rated F or G cannot be legally continued as a let, regardless of tenancy age.
What triggers the MEES obligation?
A valid, compliant EPC must be in place when:
- Granting a new assured shorthold tenancy (AST)
- Renewing a fixed-term tenancy
- A fixed-term tenancy rolls into a statutory periodic tenancy (treated as a new tenancy)
- Marketing the property for rent (EPC must be available to prospective tenants before viewing)
Short lets under four months, agricultural tenancies, and listed buildings (in limited circumstances) may be exempt.
Penalties for non-compliance
Enforcement is handled by local authorities, typically the private sector housing team. London boroughs vary significantly in enforcement intensity: Tower Hamlets, Newham, Hackney, and Southwark have run active campaigns.
| Breach Duration | Maximum Fine |
|---|---|
| Under 3 months | £5,000 per property |
| 3 months or longer | £30,000 per property |
| False information on exemption register | £5,000 |
Fines are per property, not per landlord. A portfolio landlord with five F-rated flats faces up to £150,000 in fines if all are let in breach. Enforcement actions are published on a publicly searchable database, the reputational impact is real alongside the financial penalty.
If contacted by your local authority, respond promptly with evidence of either compliance, exemption registration, or a documented improvement timeline. Councils generally prefer compliance over prosecution, and a credible plan is treated far better than silence.

Exemptions: what qualifies and how to register
Exemptions must be registered on the PRS Exemptions Register (gov.uk) before you continue letting. An unregistered exemption is not valid, this is the most common reason landlords face fines they thought they had avoided.
Cost cap exemption
All relevant improvements would cost more than £3,500 (including VAT). To qualify:
- Get quotes from at least three registered installers for each EPC-recommended improvement
- Carry out all improvements that collectively cost under £3,500 first, you cannot claim the exemption without exhausting sub-cap measures
- Submit the exemption form with evidence (quotes, completion certificates)
This exemption is valid for five years. After expiry, reassess, improvements may have become cheaper or funded through ECO4.
Consent exemption
A third party, tenant, lender, or planning authority, has refused consent in writing for the required works. The refusal must be documented with dates, method, and written confirmation. Valid for five years or until the tenant changes.
Devaluation exemption
An independent RICS surveyor confirms in writing that carrying out the required improvements would reduce the property's market value by more than 5%. Rare in practice for most London properties.
Listed building exemption
The property is listed or in a conservation area and improvements would unacceptably alter its character or appearance. Planning consent for the works was formally refused. This exemption is often misapplied, consult a solicitor before relying on it.
All exemptions last five years except the new landlord exemption (six months), which applies when you recently acquired the property through inheritance or repossession.
Common scenarios and what to do
You have an F-rated property with a current tenant
You are in breach of MEES. Options:
- Improve the property to E or above, the required route unless an exemption applies
- Check whether all relevant improvements exceed £3,500 and register a cost-cap exemption with three quotes as evidence
- Check for another qualifying exemption
Do not issue a section 21 notice to evict the tenant as a mechanism to avoid improvement costs. This is widely regarded as retaliatory eviction and is ineffective, you'd still need to improve the property before re-letting.
You have a G-rated Victorian terrace in Islington or Hackney
Victorian solid-wall properties are the problem cases. With no cavity to fill, the main routes to E are:
- Modern condensing boiler (if the existing is pre-2005)
- LED lighting throughout
- Loft insulation to 270mm
- Draught-proofing
These may collectively get a G to E or D for £500–£1,500. If the total cost of all EPC-recommended measures exceeds £3,500, document it properly with three quotes and register the exemption.
You're buying an F-rated property at auction
MEES applies from the moment you become the landlord. The new landlord exemption gives you six months to act, but factor improvement costs into your purchase calculation. An F-rated Victorian terrace with solid walls may need £8,000–£16,000 to reach E reliably.
The proposed upgrade to band C
The 2023 government consultation proposed:
- 2028: Minimum band C for new tenancies
- 2030: Minimum band C for all tenancies
The legislation has not yet been passed (May 2026), but the direction is firm. The proposed cost cap rises to £15,000, significantly higher than the current £3,500, meaning fewer properties will qualify for cost-cap exemptions under the C standard.

Frequently asked questions
- As of 2026, all privately rented residential properties in England and Wales must have a valid EPC rated E or above. This has applied to new tenancies since April 2018 and to all tenancies (including existing ones) since April 2020.
- Local authorities can issue civil penalties of up to £5,000 per property for a breach lasting fewer than three months, and up to £30,000 for a breach lasting three months or longer. Providing false information to the exemption register carries a separate £5,000 penalty. Details are published on a public database.
- Yes. Houses in Multiple Occupation fall within MEES on the same terms as standard residential lettings, provided they require an EPC. Most HMOs do. The exemption categories are identical.
- Valid exemptions: all relevant improvements would cost more than £3,500 (cost cap); consent refused by a tenant, lender, or planning authority; independent surveyor confirms works would reduce market value by 5%+; the property is listed and improvements would harm its character. All require registration on the PRS Exemptions Register with supporting evidence.
- The government consultation proposed C by 2028 for new tenancies and 2030 for all tenancies. As of May 2026 the legislation has not been passed, but policy direction has been consistent across governments. Landlords should plan for 2028 as a working deadline.
