Minimum Energy Efficiency Standards (MEES): A Landlord's Compliance Guide
MEES rules mean landlords generally can't let a property rated F or G on its EPC without a registered exemption. Here's exactly how the exemption system works, what compliance costs, and what's proposed to change.
What MEES Requires
The Minimum Energy Efficiency Standards (MEES), set out in the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, generally prohibit landlords from granting a new tenancy, or continuing an existing tenancy, of a residential property with an EPC rating of F or G, unless a valid exemption is registered.
| Effective Date | Applies To |
|---|---|
| 1 April 2018 | New tenancies and lease renewals |
| 1 April 2020 | All tenancies, including existing ones that were previously outside scope |
This means landlords with long-standing tenancies in sub-standard (F/G) properties could not simply avoid the rules by not renewing — the 2020 extension closed that gap.
The Exemption Categories
| Exemption | What It Requires |
|---|---|
| All relevant improvements made | Landlord has installed every recommended, cost-effective improvement from the EPC report, but the rating still doesn't reach E |
| Cost cap exemption | The cost of bringing the property to E would exceed the specified cap (currently £3,500 including VAT), and improvements up to that cap don't achieve E |
| Third-party consent exemption | Consent needed from a tenant, freeholder, mortgage lender, planning authority, or similar was sought but reasonably refused, or can't be obtained |
| Devaluation exemption | A suitably qualified independent surveyor confirms that specific recommended improvements would reduce the property's market value by more than 5% |
| Temporary new landlord/owner exemption | A grace period (generally 6 months) for a landlord who has recently acquired a sub-standard property, to arrange compliance or register a longer-term exemption |
Each exemption category has specific evidence requirements — for example, quotes from installers for the cost cap exemption, or written evidence of a consent request and refusal for the third-party consent exemption.
Registering an Exemption
Claiming an exemption is not automatic — landlords must formally register it on the PRS Exemptions Register, a government-run online database, providing the required supporting evidence for the specific exemption claimed. Key points:
- Registered exemptions typically last 5 years.
- After the exemption expires, the landlord must either bring the property up to the required standard or, if the underlying circumstances genuinely still apply, register again.
- Registering a false or unsupported exemption claim is itself a compliance risk — enforcement authorities can review and challenge registered exemptions.
- Failing to register a claimed exemption at all leaves the landlord with no protection, even if they believe their situation would objectively qualify.
The Cost Cap Exemption in Detail
If the total cost of the improvements needed to reach an E rating exceeds the £3,500 (including VAT) cap, a landlord can spend up to that amount on the most cost-effective available improvements and, if the property still doesn't reach E, register a cost cap exemption rather than being required to spend further.
| Scenario | Outcome |
|---|---|
| Improvements to reach E cost £2,000 | No exemption available — landlord must carry out the works and reach E |
| Improvements to reach E would cost £6,000, landlord spends the £3,500 cap on the most effective measures, still doesn't reach E | Cost cap exemption available |
| No cost-effective improvements identified at all (rare) | "All improvements made" exemption may apply instead |
This cap has been a fixed figure for some time — landlords should confirm the current cap amount directly, as it is a policy parameter that could be revised.
Penalties for Non-Compliance
| Breach Type | Typical Penalty Range |
|---|---|
| Letting a non-compliant property, breach under 3 months | Up to £5,000 (per property, historically) |
| Letting a non-compliant property, breach over 3 months or repeat breach | Up to £10,000 (per property, historically) |
| Providing false or misleading information on the PRS Exemptions Register | Separate penalty may apply |
Local authority enforcement (typically trading standards) has powers to investigate, issue compliance notices, and impose penalties — landlords should treat MEES compliance as a genuine, actively enforced legal requirement rather than a theoretical risk.
Proposed Tightening: E to C
The government has proposed raising the minimum standard for privately rented homes from E to C, reflecting a broader policy push toward decarbonising the housing stock. Key points landlords should be aware of:
- Proposed implementation dates have historically been announced and then revised or delayed — landlords should check the current, confirmed government position rather than planning around an earlier announcement.
- If and when implemented, the change would likely apply first to new tenancies, with a later deadline for all existing tenancies, mirroring the pattern used for the original E standard rollout.
- Properties currently rated E, D, or lower-C are likely to require further investment to meet any future C standard, so landlords with lower-rated properties may wish to plan improvement works proactively rather than waiting for a firm compliance deadline.
Practical Compliance Steps for Landlords
- Check your property's current EPC rating and expiry date via the government's EPC register.
- If rated F or G, get quotes for the recommended improvements on your EPC report to establish whether reaching E is achievable within the £3,500 cost cap.
- Register any valid exemption formally on the PRS Exemptions Register — don't rely on an unregistered belief that you'd qualify.
- Diarise exemption expiry dates (typically 5 years) to review and either upgrade the property or re-register in good time.
- Monitor the proposed E-to-C policy change and consider planning improvement works proactively for lower-rated properties, given the direction of regulatory travel even where exact timelines remain unconfirmed.
