MEES Regulations: The Complete Guide for UK Landlords
Everything you need to know about Minimum Energy Efficiency Standards, from the law itself to practical compliance steps.
MEES stands for Minimum Energy Efficiency Standards. These regulations set the minimum energy efficiency level that privately rented properties must achieve. First introduced in 2015 and coming into force in 2018, MEES has progressively raised the bar for rental property standards.
Here is the short version. Since 1 April 2020 the minimum has been band E, and it has not moved since. Band D is legal to let. Only F and G are barred, and only where no exemption is registered. Band C by October 2030 is a government proposal that still needs an Act of Parliament behind it, so it is worth planning for and not worth panicking over.
MEES applies in England and Wales only. Scotland and Northern Ireland run their own rules, and neither the cost cap nor the PRS Exemptions Register applies there. This guide covers what the regulations require today and what would change if the proposal is legislated.
What is MEES?
MEES regulations are set out in The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. They establish the minimum Energy Performance Certificate (EPC) rating that privately rented properties must achieve before they can be let.
The regulations work by making it unlawful to grant a new tenancy (or renew an existing tenancy) of a property that does not meet the minimum energy efficiency standard, unless a valid exemption has been registered.
History and Evolution of MEES
MEES regulations have evolved significantly since their introduction. Understanding this history helps explain the current framework and where it is heading.
Regulations Enacted
The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 were made under the Energy Act 2011. They established the framework for minimum standards but did not come into force immediately.
MEES for New Tenancies
The first phase came into force. Landlords could no longer grant new tenancies for properties rated F or G. The minimum standard was EPC E (score of 39 or above).
MEES for All Tenancies
The second phase extended requirements to existing tenancies. All privately rented properties had to meet the E minimum, regardless of when the tenancy began. The cost cap was£3,500 and maximum penalty was £5,000.
Proposed EPC C standard
In its response of 21 January 2026, published with the Warm Homes Plan, the government said it intends to raise the minimum to EPC C (score 69+) from 1 October 2030. The cost cap would rise from £3,500 to £10,000 and the maximum penalty from £5,000 to £30,000. This is a proposal, not law: Government must first take new powers through an Act of Parliament, then lay a statutory instrument amending the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. The target is for the new rules to be in force during 2027.
Current Requirements
These are the rules in force in England and Wales today, and the only ones a local authority can enforce against you right now. Band D is perfectly legal to let. Only F and G are barred without a registered exemption.
| Requirement | Current Standard |
|---|---|
| Minimum EPC rating | E |
| Minimum EPC score | 39 out of 100 |
| Cost cap for exemption | £3,500 (including VAT) |
| Maximum penalty | £5,000 per property |
| Exemption duration | 5 years from registration |
| Applies to | All new and existing tenancies |
What Is Proposed for 2030
On 21 January 2026 the government published its response alongside the Warm Homes Plan, setting out an intention to raise the minimum to EPC C from 1 October 2030. None of it is law yet. Government must first take new powers through an Act of Parliament, then lay a statutory instrument amending the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. The target is for the new rules to be in force during 2027. Until that happens, the column on the left is the one that binds you.
- Cost cap: £3,500
- Max penalty: £5,000
- Exemption: 5 years
- Proposed cost cap: £10,000, or 10% of value below £100,000 - see exemptions guide
- Proposed max penalty: £30,000
- Proposed exemptions: 10 years on three grounds only, otherwise 5
Which Tenancies Are Covered?
MEES regulations apply to properties let under specific tenancy types. The vast majority of private rentals fall within scope, but some arrangements are excluded.
Covered by MEES
- Assured Shorthold Tenancies (ASTs)
The most common tenancy type for private rentals in England
- Assured Tenancies
Less common but still within scope
- Regulated Tenancies
Pre-1989 tenancies with rent control
- Domestic Agricultural Tenancies
Farm worker accommodation
Not Covered by MEES
- Social Housing
Council and housing association properties have separate regulations
- Licences to Occupy
Not a tenancy, so MEES does not apply
- Holiday Lets (under 4 months/year)
Short-term lets do not require EPC
- Properties Not Requiring EPC
Some listed buildings, temporary structures, etc.
Exemptions and the PRS Exemptions Register
Not every property can reach the minimum standard within a reasonable budget. MEES allows landlords to register an exemption where genuine barriers exist. An exemption is not automatic: you must register it on the PRS Exemptions Register before you let, and most exemptions last 5 years and are specific to both the property and the current landlord.
The Five Main Exemption Types
1. High-Cost (Cost Cap) Exemption
Applies where all relevant improvements cannot be made within the cost cap of £3,500 including VAT (a rise to £10,000 is proposed for the 2030 standard). You must have installed every measure the cap allows before registering.
How to register: Upload three quotes for the outstanding work showing the cost exceeds the cap, plus evidence of measures already installed.
2. All Improvements Made Exemption
Applies where all relevant energy efficiency measures have been installed but the property still falls below the minimum rating. There is nothing further that can reasonably be done.
How to register: Provide the EPC and recommendation report showing every listed measure has been completed.
3. Wall Insulation Exemption
Applies where cavity, external, or internal wall insulation would negatively affect the fabric or structure of the property. This must be supported by expert opinion.
How to register: Upload a written report from a suitably qualified engineer, surveyor, or installer confirming the risk.
4. Third-Party Consent Exemption
Applies where consent needed for improvements has been refused, or granted only with conditions you cannot reasonably meet. This covers tenants, lenders, superior landlords, or planning authorities.
How to register: Provide evidence of the request and the refusal or conditions, such as correspondence or a decision notice.
5. Property Devaluation Exemption
Applies where a measure would reduce the market value of the property by more than 5 per cent. This is uncommon and needs professional valuation evidence.
How to register: Upload a report from a RICS-qualified surveyor confirming the expected loss in value.
Enforcement and Penalties
Local authorities (usually Trading Standards or Environmental Health) are responsible for enforcing MEES. They have powers to request information, issue compliance notices, and impose financial penalties.
Enforcement Powers
- 1Request for Information: Local authorities can require landlords to produce EPC certificates, tenancy agreements, and other evidence of compliance.
- 2Compliance Notice: A formal notice requiring the landlord to take action to comply with MEES within a specified timeframe.
- 3Penalty Notice: Financial penalties can be imposed without court proceedings. Penalties are proportionate to the breach.
- 4Publication: Details of penalties are published on the PRS Exemptions Register for a minimum of 12 months.
Penalty amounts in force today
| Offence | Maximum penalty |
|---|---|
| letting a non-compliant property for less than 3 months | £2,000 |
| letting a non-compliant property for 3 months or more | £4,000 |
| providing false or misleading information | £1,000 |
| failing to comply with a compliance notice | £2,000 |
| Maximum per property, all breaches combined | £5,000 |
The £5,000 is a total ceiling per property, not a per-breach one, so a single property cannot attract more than that however many tiers apply. The government has proposed lifting that ceiling to £30,000 alongside the band C standard. It has not published a revised tier breakdown, and the proposal is not law.
The Cost Cap Explained
The cost cap is the ceiling on how much a landlord is expected to spend on energy efficiency improvements before a high-cost exemption can be claimed. It exists so that no landlord is forced to spend an unlimited amount chasing a rating a property physically cannot reach.
| Cost Cap | Amount |
|---|---|
| Current cap (EPC E standard) | £3,500 including VAT |
| Proposed cap (EPC C standard) | £10,000 including VAT |
When Improvements Are Not Enough
If you spend up to the cap and the property still falls below the required rating, you are not expected to keep spending. You install every measure the cap allows, then register a high-cost exemption with your evidence. The property can then be let while the exemption is valid, typically for 5 years.
How to Comply with MEES
Compliance with MEES requires either achieving the minimum EPC rating or registering a valid exemption. Here is the practical process:
Obtain a Valid EPC
If you do not have a current EPC, or if your EPC has expired, you must get one from a qualified Domestic Energy Assessor. The EPC must be valid on the date you enter into a new tenancy or on the compliance deadline date.
Find an energy assessor on GOV.UKCheck the Rating
Compare your EPC rating to the minimum in force, which is E (score 39+). D and E both pass. If the proposed band C standard is legislated, that bar would move to a score of 69 from 1 October 2030, so it is worth knowing your number either way.
If Below Minimum: Improve or Exempt
If your rating is below the minimum, you have two options:
Option A: Improve
Make energy efficiency improvements to raise the rating above the minimum threshold.
Option B: Exempt
If qualifying for an exemption, register it on the PRS Exemptions Register before letting.
Document Everything
Keep records of your EPC, any improvement works carried out (including quotes and invoices), and any exemption registration. You may need to provide this evidence to local authority enforcement officers.
Frequently Asked Questions
What is the minimum EPC rating for a rental property right now?
The current minimum standard is EPC E (a score of 39 or above). Properties rated F or G cannot be legally let unless a valid exemption is registered. From October 2030 the proposed minimum rises to EPC C (score 69+).
How much can I be fined for breaching MEES?
Civil penalties are currently capped at £5,000 in total per property, across all breaches combined. The government has proposed raising that maximum to £30,000, but the change is not yet law. Penalties are issued by the local authority, and a landlord with several non-compliant properties can be penalised on each one.
How long does a MEES exemption last?
Every exemption in force lasts 5 years from the date of registration, apart from the new-landlord ground, which lasts 6 months. Exemptions are specific to both the property and the landlord: they do not transfer to a new owner, so a buyer must re-register or improve the property. The government has proposed 10-year exemptions on three grounds (cost cap, property value adjustment and negative impacts), but that change is not law.
What happens if improvements are not enough to reach the required rating?
If you have spent up to the cost cap and the property still falls short, you can register a high-cost exemption. You must have carried out all improvements possible within the cap and provide evidence, such as quotes and invoices, on the PRS Exemptions Register.
