Every rental property in England and Wales must have a valid Energy Performance Certificate. More than that, it must meet a minimum energy efficiency standard before it can be legally let. The rules have been in place since 2018 and are set to tighten further in the coming years. If you are a landlord, understanding your EPC obligations is essential to staying compliant and avoiding penalties of up to 5,000 pounds.
What Is an EPC?
An Energy Performance Certificate rates the energy efficiency of a building on a scale from A (most efficient) to G (least efficient). It is produced by a qualified domestic energy assessor who visits the property and assesses factors such as insulation, heating systems, windows, lighting, and hot water provision. The certificate is valid for 10 years from the date of issue. You must have a valid EPC before marketing a property for rent and must make it available to prospective tenants.
The Current Minimum Standard
Under the Minimum Energy Efficiency Standards (MEES), which came into force in April 2018 under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, it is unlawful to grant a new tenancy of a property with an EPC rating below E. Since April 2020, this rule has applied to all existing tenancies as well, not just new lets. If your property is rated F or G, you cannot legally let it unless you have a valid exemption registered on the PRS Exemptions Register.
Exemptions and the Cost Cap
There are limited exemptions to the minimum E rating requirement. The most commonly used is the cost cap exemption. If you have made all improvements that can be made for 3,500 pounds (including VAT) and the property still does not reach an E rating, you can register a cost cap exemption. This exemption lasts for five years, after which you must reassess. Other exemptions include consent exemptions (where a freeholder refuses consent), devaluation exemptions (where works would reduce property value by more than five percent), and wall insulation exemptions (where an expert advises that wall insulation is not appropriate).
Penalties for Non-Compliance
If you let a property that falls below the minimum E rating without a valid exemption, the local authority can impose penalties. For letting a non-compliant property for less than three months, the penalty is up to 2,000 pounds. For letting for three months or more, the penalty rises to up to 4,000 pounds. Providing false or misleading information on the PRS Exemptions Register carries a penalty of up to 1,000 pounds. The maximum total penalty per property is 5,000 pounds. Penalties are cumulative, so each breach can be penalised separately.
Future Changes: The Move to a C Rating
The government has signalled its intention to raise the minimum EPC standard for rental properties to a C rating. This proposal has been discussed for several years and was included in various consultations. As of early 2026, the requirement for a C rating has not been enacted into law, but it remains a stated policy objective with a target date of 2030. If and when this change is legislated, landlords with properties rated D or E will need to carry out further energy efficiency improvements or register for an exemption. The cost cap for improvements is also expected to increase, potentially to 10,000 pounds, though final figures will depend on the legislation.
How to Improve Your EPC Rating
If your property is close to the minimum threshold or you want to prepare for future changes, there are several cost-effective improvements you can make. These include:
- Loft insulation (typically the cheapest and most effective single measure)
- Cavity wall insulation where applicable
- Upgrading the boiler to a more efficient model
- Installing a smart thermostat or programmable heating controls
- Draught-proofing windows and doors
- Upgrading to LED lighting throughout
The assessor's report includes recommended improvements and their estimated impact on the rating, so use this as your starting point. You must provide the EPC to tenants before the start of the tenancy. Under the Energy Performance of Buildings (England and Wales) Regulations 2012, failing to provide an EPC can result in a penalty of up to 200 pounds. Under the Renters' Rights Act 2025, non-compliance could also affect your ability to serve valid notices under Section 8.
