Energy Performance Certificates (EPCs) are a legal requirement for rental properties in Wales. The Minimum Energy Efficiency Standards (MEES) regulations set the minimum acceptable rating, with proposals for higher standards in coming years. This guide explains all EPC requirements for Welsh landlords.
EPC Overview
An Energy Performance Certificate rates your property's energy efficiency on a scale from A (most efficient) to G (least efficient). The certificate includes:
- Current energy efficiency rating
- Potential rating if improvements made
- Environmental impact rating
- Estimated energy costs
- Recommendations for improvements
| Rating | SAP Points | Status for Letting |
|---|---|---|
| A | 92-100 | Can let |
| B | 81-91 | Can let |
| C | 69-80 | Can let |
| D | 55-68 | Can let |
| E | 39-54 | Minimum standard (can let) |
| F | 21-38 | Cannot let (unless exempt) |
| G | 1-20 | Cannot let (unless exempt) |
When You Need an EPC
You must have a valid EPC in the following situations:
- Before marketing a property for rent
- When entering into a new occupation contract
- When renewing or extending an existing contract
- Upon request from a prospective contract-holder
EPC Validity
EPCs are valid for 10 years from the date of issue. However, if you make significant improvements to energy efficiency, consider getting a new assessment to reflect the improvements.
Providing the EPC
You must provide the EPC to prospective contract-holders:
- Free of charge
- At the earliest opportunity
- Before an occupation contract is entered into
- In property listings and advertisements

MEES Regulations
The Minimum Energy Efficiency Standards (MEES) regulations apply in Wales. Key requirements include:
Current Requirements
- Minimum EPC rating of E required
- Applies to new tenancies since April 2018
- Applies to all existing tenancies since April 2020
- Properties rated F or G cannot be legally let (unless exempt)
Penalties for Non-Compliance
| Breach | Penalty (less than 3 months) | Penalty (3+ months) |
|---|---|---|
| Letting a sub-standard property | 10% of rateable value (min £5,000) | 20% of rateable value (min £10,000) |
| Providing false/misleading information | Up to £5,000 | |
| Failure to comply with compliance notice | Up to £5,000 | |
Maximum Penalty
The maximum penalty for a single property is capped at £5,000 for a single penalty notice, with a maximum of £30,000 over 18 months across all breaches.
Exemptions
If your property cannot reach an E rating, you may be eligible for an exemption. Exemptions must be registered on the PRS Exemptions Register.
Types of Exemption
- Cost cap exemption: All relevant improvements would cost more than £3,500 (inc. VAT)
- Third party consent: Required consent (e.g., planning) has been refused
- Devaluation: An independent surveyor confirms improvements would reduce property value by more than 5%
- Wall insulation: Expert advice says wall insulation would damage the property
Registering an Exemption
- Exemptions are valid for 5 years
- Must be registered on the national PRS Exemptions Register
- Supporting evidence must be provided
- New landlord cannot rely on previous owner's exemption
Improving Your Rating
Common improvements to boost your EPC rating include:
Low-Cost Improvements
- LED lighting throughout
- Loft insulation (270mm recommended)
- Draft proofing windows and doors
- Hot water cylinder insulation
- Thermostatic radiator valves
Higher-Cost Improvements
- Double or triple glazing
- Cavity wall insulation
- External or internal wall insulation
- New efficient boiler
- Solar panels
- Heat pump installation
Welsh Government Grants
The Welsh Government offers various grants and schemes to help improve energy efficiency, including the Warm Homes Programme. Check eligibility for funding before making improvements.

Future Changes
The Welsh Government is considering raising minimum EPC standards in line with net zero commitments. Proposed changes include:
- Potential increase to minimum C rating
- Phased implementation for existing properties
- Higher cost cap for required improvements
- Integration with Warm Homes Programme
Forward Planning
Even if not yet required, consider improving properties to C rating now. This future-proofs your investment and can make properties more attractive to tenants concerned about energy costs.

Do I need a new EPC for each new contract-holder?
No, as long as your current EPC is still valid (within 10 years) and meets the minimum E rating, you can use the same certificate. You must provide a copy to each new contract-holder.
What if my EPC expires during an occupation contract?
You need a valid EPC when entering into a contract, but expiry during the contract doesn't require immediate renewal. You'll need a new EPC before any new letting or marketing.
Can contract-holders see my EPC online?
Yes, EPCs are public documents. Anyone can search for a property's EPC on the government's EPC register using the address.
Who can produce an EPC?
Only accredited Domestic Energy Assessors can produce EPCs. Ensure your assessor is registered with an approved accreditation scheme.
