An Energy Performance Certificate (EPC) rates a property's energy efficiency from A (most efficient) to G (least efficient). For private landlords in England and Wales, holding a valid EPC is a legal requirement before marketing a property for let — and the Minimum Energy Efficiency Standards (MEES) impose a floor below which you cannot lawfully let.
Your rental property must have an EPC rating of E or above. You cannot legally let a property rated F or G unless a valid exemption is registered. The government has proposed raising the minimum to C for new tenancies from 2030 — budget for upgrades now.
What is an EPC and how long is it valid?
An EPC is produced by an accredited domestic energy assessor after a visit to the property. It shows the current energy rating, the potential rating if recommended improvements are made, and estimated running costs. An EPC is valid for 10 years from the date of issue. You can reuse the same EPC for multiple tenancies within that period, provided the property has not been materially altered.
- Valid for 10 years from date of assessment
- Must be lodged on the national EPC Register (gov.uk/find-energy-certificate)
- Must be provided to a prospective tenant before they view the property
- Must be included in marketing materials where a rating is advertised
- Must be handed to the tenant at the start of the tenancy (or emailed if tenant agrees)
Minimum Energy Efficiency Standards (MEES)
The Energy Efficiency (Private Rented Property)(England and Wales) Regulations 2015 prohibit landlords from letting a domestic property with an EPC rating below E. This applies to:
- New tenancies granted on or after 1 April 2018
- Existing tenancies renewed or rolled over on or after 1 April 2019
- All privately rented properties regardless of tenancy date from 1 April 2020 (subject to registered exemptions)
Letting an F or G rated property without a valid registered exemption is a civil breach. Local authorities can issue financial penalties of up to £5,000 per property for breaches of up to 3 months, rising to £10,000 for longer breaches. Serious or repeated non-compliance can also trigger a public register entry and affect your ability to serve possession notices.
MEES exemptions
If your property cannot reach an E rating despite making all 'relevant improvements', you may register an exemption on the PRS Exemptions Register. Exemptions last 5 years (or until you sell or the tenancy ends, whichever is sooner). Valid exemption grounds include:
- High cost exemption: The cheapest package of relevant improvements exceeds the £3,500 cost cap (including VAT)
- All improvements made exemption: You have made all relevant improvements but the property still falls below E
- Wall insulation exemption: Written expert opinion confirms that cavity/external/internal wall insulation would damage the property's fabric
- Consent/debenture exemption: Third-party consent (e.g., freeholder, planning authority) has been refused or granted only on unreasonable conditions
- New landlord exemption (temporary): 6-month grace period where you became the landlord by inheritance, court order, or repossession
The EPC C target — what is coming
The previous government's proposal to require EPC C for new tenancies from 2025 was abandoned in 2023. The current government has signalled an intention to require EPC C for new tenancies from 2030 and for all tenancies from 2033 — but as of May 2026 no new regulations are in force. Landlords with older stock should use this window to plan and budget for fabric improvements, heat pump installations, and insulation upgrades.
Some landlords may qualify for subsidised insulation under the Great British Insulation Scheme (GBIS) or ECO4. Check eligibility at gov.uk/apply-great-british-insulation-scheme. Funding is targeted at lower-rated properties in lower-income areas.
Which properties are exempt from EPC requirements?
- Listed buildings where compliance with energy efficiency requirements would unacceptably alter their character or appearance
- Buildings used for less than 4 months per year
- Stand-alone buildings with a total useful floor area of less than 50 m²
- Short-term holiday lets (no more than 31 days per let, and no more than 4 months total per year)
- Properties where consent has been refused by the relevant authority
Practical landlord checklist
- Check the EPC Register for your property — confirm rating and expiry date
- If rated F or G: commission an assessor to identify the cheapest improvement package before the next tenancy
- If improvements are affordable (under £3,500): carry them out and commission a new EPC before re-letting
- If improvements cost more: register the high-cost exemption on the PRS Exemptions Register before letting
- Keep a copy of the EPC and any exemption registration in your compliance file with the tenancy documents
- Plan now for the EPC C target expected from 2030 — fabric-first improvements (insulation, draught-proofing) have the best payback
