Energy Performance Certificates are now essential for UK landlords. With minimum standards rising, understanding EPC requirements and how to improve your property's rating is crucial for compliance and letting success.
EPC Basics
An Energy Performance Certificate rates a property's energy efficiency on a scale from A to G, with A being the most efficient. The certificate also provides recommendations for improvement.
What the EPC Shows
EPCs display two ratings: current efficiency and potential efficiency if improvements are made. They also estimate running costs and show the property's environmental impact.
When You Need an EPC
- Before marketing a property for rent
- Before a new tenancy starts
- When an existing EPC expires (10-year validity)
- If significant improvements have been made
EPC Assessors
EPCs must be produced by accredited assessors. They inspect the property, assess insulation, heating, lighting, and other factors, then produce the certificate and recommendations.
Current Requirements (2026)
The Minimum Energy Efficiency Standards (MEES) set the baseline for rental properties in England and Wales.
Current Minimum: E Rating
Since April 2020, it has been illegal to let a property with an EPC rating below E in England and Wales, whether to new or existing tenants.
| Rating | Status | Action Required |
|---|---|---|
| A-C | Future-proof | None required currently |
| D | Compliant now, changes coming | Plan improvements before 2028 |
| E | Minimum acceptable | Urgent improvements needed |
| F-G | Non-compliant | Cannot legally let |
Penalties for Non-Compliance
Letting a non-compliant property can result in penalties:
- Up to £5,000 per property for renting out F/G rated property
- Publication on public register of non-compliant landlords
- Tenant claims for substandard accommodation
Upcoming Changes
The government has proposed raising the minimum EPC rating for rental properties. While exact dates have been delayed, the direction is clear.
Proposed Changes
The government has indicated that rental properties will need a minimum C rating in the future. Originally proposed for 2025 (new tenancies) and 2028 (all tenancies), exact implementation dates are subject to consultation.

Scotland and Northern Ireland
Scotland and Northern Ireland have their own energy efficiency requirements:
- Scotland - working toward minimum E, with C rating ambitions
- Northern Ireland - currently minimum E required
Improving Your EPC Rating
Various improvements can boost your rating. Start with recommendations on your current EPC.
Common Improvements
| Improvement | Typical Cost | Rating Impact |
|---|---|---|
| Loft insulation (270mm) | £300-500 | Up to +10 points |
| Cavity wall insulation | £500-1,500 | Up to +15 points |
| LED lighting throughout | £100-300 | +3-5 points |
| New condensing boiler | £2,000-3,500 | Up to +20 points |
| Double glazing | £3,000-8,000 | +5-10 points |
| Smart heating controls | £200-400 | +3-5 points |
Cost-Effective First Steps
- Install LED bulbs throughout
- Top up loft insulation to 270mm
- Draught-proof doors and windows
- Install smart thermostat
- Lag hot water cylinder and pipes
Exemptions
In certain circumstances, properties can be exempt from MEES requirements.
Available Exemptions
- Cost cap exemption - if no improvements under the cost cap would raise rating to E
- All improvements made - if all relevant improvements already done
- Wall insulation exemption - if this would damage the property
- Third party consent - if consent for improvements is refused
- Devaluation exemption - if improvements would devalue by 5%+
Exemption Registration
Exemptions must be registered on the PRS Exemptions Register. They typically last 5 years before reassessment is needed. Simply claiming exemption without registration is not valid.

How long is an EPC valid?
EPCs are valid for 10 years. However, if you make significant improvements, getting a new EPC can demonstrate the higher rating to prospective tenants.
Do I need a new EPC for every tenancy?
No, as long as the EPC is still valid (within 10 years). However, you must provide the EPC to prospective and new tenants at the start of each tenancy.
Can I challenge an EPC rating?
If you believe the assessment was inaccurate, you can commission a new assessment from a different assessor. Ratings can vary slightly between assessors based on their observations.
What grants are available for improvements?
Various grants exist depending on your location and circumstances. Check the Energy Company Obligation (ECO) scheme and local authority grants. Eligibility varies by property and owner situation.
