MEES and the EPC Band C upgrade path
Minimum energy efficiency standards for rental properties. Current Band E rules, the proposed Band C target, and how to prepare.
What are the MEES regulations?
The Minimum Energy Efficiency Standards (MEES) were introduced by the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. They set a minimum Energy Performance Certificate (EPC) rating that rental properties must meet before they can be legally let.
Current minimum: Band E
Since April 2020, it has been unlawful to let any domestic private rented property with an EPC rating below Band E. This applies to all tenancies, not just new ones.
Properties rated F or G cannot be legally let unless the landlord has registered a valid exemption on the PRS Exemptions Register.
The penalty for non-compliance
| Breach | Penalty |
|---|---|
| Letting a sub-standard property for less than 3 months | Up to £2,000 |
| Letting a sub-standard property for 3 months or more | Up to £4,000 |
| Providing false or misleading information on the exemptions register | Up to £1,000 |
| Failing to comply with a compliance notice | Up to £2,000 |
| Maximum total penalty per property per breach | £5,000 |
Proposed future minimum: Band C
The government has consulted on raising the minimum EPC rating to Band C. The exact implementation date has not been confirmed and is still subject to government consultation. However, landlords should be planning ahead now.
When Band C becomes mandatory, properties rated D or E will also need to be upgraded or exempted.
Exemptions
If you cannot reach the minimum rating cost-effectively, you may be able to register an exemption. Exemptions last for 5 years and must be registered on the PRS Exemptions Register. The main exemptions are:
- Cost cap exemption: All relevant improvements have been made up to the cost cap (currently £3,500 including VAT), and the property still doesn't meet the minimum
- Wall insulation exemption: A wall insulation measure is recommended but an installer has confirmed it would negatively impact the property
- Consent exemption: A third party whose consent is required (e.g. a freeholder, planning authority, or tenant) has refused
- Devaluation exemption: An independent surveyor has confirmed that the recommended measures would reduce the property's value by more than 5%
EPC improvement recommendations
Every EPC includes a list of recommended improvements. These are the most common and typically the most cost-effective:
| Improvement | Typical cost | Typical EPC impact |
|---|---|---|
| Loft insulation (270mm) | £300–£600 | 5–10 points |
| Cavity wall insulation | £500–£1,500 | 10–15 points |
| Draught-proofing | £100–£300 | 2–5 points |
| Low-energy lighting | £50–£150 | 2–5 points |
| Smart heating controls | £200–£400 | 3–7 points |
| Condensing boiler upgrade | £2,000–£3,500 | 10–20 points |
| Double glazing | £3,000–£7,000 | 5–10 points |
| External wall insulation | £8,000–£15,000 | 15–25 points |
Prioritise the cheapest improvements with the biggest impact first. Loft insulation and cavity wall insulation typically give the best return.
How to prepare for Band C
- Check your current EPC rating. If you don't have a valid EPC, get one.
- Read the recommendations. Your EPC lists specific improvements for your property.
- Get quotes for the top recommendations. Start with the cheapest, highest-impact measures.
- Budget for improvements. Band C may require spending more than the current £3,500 cost cap (the government may increase it).
- Act early. Don't wait for the deadline. Contractors and materials will be in high demand once a date is confirmed.
How LetShield helps
LetShield flags your property's EPC rating on the dashboard and tracks the certificate's expiry date. You'll get reminders before it expires, and the compliance map highlights whether your property meets the current minimum standard.
