MEES 2030: Complete Landlord Guide to Minimum Energy Efficiency Standards
The Minimum Energy Efficiency Standards (MEES) are one of the most significant regulatory changes facing private landlords in England and Wales. Under current rules, you cannot legally let a property with an EPC rating below E. Under proposed — but not yet legislated — changes, this threshold is expected to rise to EPC C by 2030.
This guide explains where the law stands today, what changes are proposed, what the fines are, and what you should do now.
What are MEES?
The Minimum Energy Efficiency Standards (MEES) were introduced under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. They set a minimum EPC rating that properties must achieve before they can be legally let.
MEES apply to privately rented domestic properties in England and Wales. Scotland and Northern Ireland have separate rules.
Current MEES rules (2026)
Since 1 April 2020, all private rental properties in England and Wales — whether starting a new tenancy or continuing an existing one — must have a valid EPC with a rating of at least E.
- Properties rated A, B, C, D, or E: can be legally let
- Properties rated F or G: cannot be legally let without a registered exemption
What's changing: the proposed 2030 requirement
The government has consulted on raising the MEES threshold to EPC C for all private rental properties by 2030. These changes have not yet been legislated — they remain a policy proposal — but the direction of travel is clear.
What are the fines?
Under current MEES rules, the maximum fine for letting a property below EPC E (without a registered exemption) is £30,000. Local authorities are responsible for enforcement. Fines are calculated based on how long the property has been non-compliant and the property's rateable value.
The proposed 2030 regime is expected to maintain fines at the same level — up to £30,000 per property.
EPC exemptions
In some circumstances, landlords can legally continue letting a property that doesn't meet the MEES threshold, by registering an exemption on the PRS Exemptions Register. Valid exemptions include:
- All improvements made — You've made all cost-effective improvements and the property still doesn't reach the required rating
- High cost — The cost to reach the threshold would exceed the relevant cap (currently £3,500 including VAT for domestic properties)
- Wall-only properties — Certain older or listed properties where no improvements are technically possible
- Tenant consent withheld — Your tenant has refused to allow works
- Devaluation — A surveyor has confirmed improvements would reduce the property's value by 5% or more
- Temporary exemption — 6 months for newly acquired properties or following changes in tenancy
Exemptions last 5 years and must be registered at gov.uk.
What you should do now
- Check every property's EPC rating. If you don't have an up-to-date EPC, get one. Certificates last 10 years from the lodgement date.
- Identify properties rated D. These are currently compliant but at risk under proposed 2030 changes. Plan upgrades now while prices and grant availability are better.
- Get quotes for upgrades. For each property below C, get recommendations from the EPC certificate and quotes from certified installers. Costs vary significantly by property type.
- Check grant eligibility. ECO4 and GBIS can fund upgrades at no cost for eligible properties — landlords with lower-income tenants may qualify.
- Use a certified installer. TrustMark and MCS-certified installers can apply for grant funding on your behalf and provide work backed by quality guarantees.
The new EPC methodology: what landlords need to know
The government is introducing a new method for calculating EPC ratings — the Home Energy Model (HEM) — expected to replace the current SAP methodology in 2027. This could change your property's EPC rating, even without any physical changes.
Properties with gas heating may see their ratings fall. Properties with low-carbon heating (heat pumps, for example) may see ratings improve. The full impact is not yet known. We will update this guide when the HEM is confirmed.
Frequently asked questions
What is the current MEES requirement for landlords?
Since April 2020, landlords in England and Wales cannot let a property with an EPC rating below E. This applies to all tenancies including new and existing. Properties rated F or G cannot be legally let without a valid exemption registered on the government's PRS Exemptions Register.
What is the proposed 2030 MEES requirement?
Under proposed regulations, all rental properties would need to achieve EPC C by 2030. New tenancies would need to meet EPC C from 2028. These dates have not yet been legislated — they are proposals following government consultation. Timelines may change.
What are the fines for not meeting MEES?
Under current rules, fines for letting a property below EPC E (without a registered exemption) can reach £30,000 per property. Local authorities are responsible for enforcement.
Can I get an exemption from MEES?
Yes. Exemptions are available in specific circumstances — including if all improvements have been made and the property still doesn't reach the threshold, or if works would cost more than the cap (currently £3,500). Exemptions must be registered at gov.uk and last 5 years.
Does MEES apply in Scotland?
MEES applies to England and Wales only. Scotland has its own energy efficiency requirements for private rentals under the Energy Efficiency (Domestic Private Rented) (Scotland) Regulations.
How much does it cost to improve from D to C?
It depends on the property. Common improvements to reach C from D include loft insulation (£300–£600), cavity wall insulation (£500–£1,500), or heating controls (£100–£500). Some properties need more significant work. Use our portfolio checker to see the specific recommendations for your property.
