EPC minimum standards: what the proposed Band C target means for landlords.

Energy Performance Certificates (EPCs) are a legal requirement for privately rented properties in England. The current minimum standard is Band E, and landlords cannot let a property below that rating unless a valid exemption applies. The government has proposed raising the minimum to Band C in future, a change that would affect a substantial number of rental properties. This article sets out the current legal position, the penalty regime for non-compliance, and what the proposed Band C target means for landlords planning ahead. What is an EPC? An Energy Performance Certificate (EPC) rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). For privately rented properties in England, an EPC must be obtained before the property is let and provided to tenants free of charge at the start of the tenancy. (Source: MEES Regulations guidance, GOV.UK; How to Rent guide, DLUHC, October 2023.) An EPC is valid for ten years. The rating is based on the property's construction, insulation, heating system, windows and other fixed features. What is the current minimum standard? The Minimum Energy Efficiency Standards (MEES) Regulations came into force for new tenancies from 1 April 2018 and were extended to all existing tenancies from 1 April 2020. Since 1 April 2020, landlords may not let a domestic property on any tenancy if the EPC rating is F or G, unless a valid exemption has been registered. (Source: Domestic private rented property: minimum energy efficiency standard — landlord guidance, GOV.UK.) The current minimum standard is therefore Band E. A property rated F or G cannot lawfully be let without an exemption. What exemptions exist under the current rules? A landlord may register an exemption where the cost of the required improvements would exceed the cost cap, where relevant improvements are not possible due to the property's construction or third-party consent requirements, or where a newly let property has recently received a low EPC rating. Exemptions are registered on the PRS Exemptions Register, which is publicly searchable. An exemption is valid for five years, after which the landlord must reassess whether improvements can now be made. (Source: Domestic private rented property: minimum energy efficiency standard — landlord guidance, GOV.UK.) What are the penalties for non-compliance with the current Band E requirement? If a local authority confirms that a property is or has been let in breach of the MEES Regulations, it may issue a financial penalty. The maximum penalties per property per breach are as follows. For letting a non-compliant property for less than three months, the maximum penalty is £2,000. For letting a non-compliant property for three months or more, the maximum penalty is £4,000. For registering false or misleading information on the PRS Exemptions Register, the maximum penalty is £1,000. For failing to comply with a compliance notice issued by the local authority, the maximum penalty is £2,000. The maximum total fine per property is £5,000. (Source: Domestic private rented property: minimum energy efficiency standard — landlord guidance, GOV.UK.) In addition to financial penalties, the local authority may publish details of the breach for at least 12 months. A local authority may serve a compliance notice on a landlord up to 12 months after a suspected breach, and may impose a penalty up to 18 months after the breach. (Source: Domestic private rented property: minimum energy efficiency standard — landlord guidance, GOV.UK.) What is the proposed Band C target? The government has proposed raising the minimum EPC standard for privately rented properties in England to Band C. This proposal was set out in consultation and is referenced in the Renters' Rights Act 2025 context, but as of the date of this article it has not been enacted into law. No confirmed implementation date has been legislated for. The current source material — the GOV.UK MEES landlord guidance — confirms the existing Band E requirement as the enforceable standard. The Band C proposal remains a stated policy intention. Landlords should monitor government announcements for a confirmed timetable. What percentage of rental properties would be affected? A significant proportion of privately rented homes in England currently fall below Band C. Properties built before the 1980s, those with older heating systems, single-glazed windows, or poor wall and loft insulation are most likely to require work to meet a Band C standard. The exact scale of required investment varies considerably by property type and age. What improvements typically raise an EPC rating? Common improvements that raise EPC ratings include loft insulation, cavity wall insulation, solid wall insulation, double or triple glazing, upgrading from an older boiler to a modern condensing boiler, installing a heat pump, adding solar photovoltaic panels, and improving hot water cylinder insulation. The EPC assessment itself will indicate which improvements would have the greatest impact on a specific property's rating. What should landlords do now? Landlords whose properties are currently rated E, F or G should check their EPC rating and expiry date. Any property let on a rating of F or G without a valid exemption is already in breach of the current MEES Regulations and is exposed to financial penalties now, not in the future. Landlords with properties rated D or E should consider what improvements might be needed to reach Band C if the proposed target is enacted, and factor this into maintenance and investment planning. Getting an updated EPC assessment is a sensible first step, as some older EPCs will not reflect improvements already made to the property. Landlords should not wait for the Band C target to be confirmed before addressing a property that is already non-compliant with the Band E requirement. What this means for landlords The current law is clear: no property rated F or G may be let without a valid exemption registered on the PRS Exemptions Register. Penalties for non-compliance reach up to £4,000 per property for breaches lasting three months or more, with a maximum total of £5,000 per property. The proposed Band C target is not yet law. No landlord is currently required to meet Band C. However, it is a stated government intention, and landlords with lower-rated properties should treat it as a likely future requirement and plan accordingly. Checking the EPC rating and expiry date for every property in a portfolio is the minimum step any landlord should take now. An EPC is valid for ten years; many properties last assessed several years ago may have since had improvements made that would increase the rating if reassessed. Registering any legitimate exemption on the PRS Exemptions Register is essential before letting a sub-standard property. Letting without a valid exemption is a breach of the MEES Regulations regardless of whether the landlord was aware of the obligation.
