Understanding EPC Exemptions
Most properties in England and Wales need an Energy Performance Certificate when they're sold or rented. But not all of them. There are specific exemptions written into law — and separate MEES exemptions that let landlords rent out properties below the minimum E rating. This guide covers every exemption, how to claim them, and the myths that trip people up.
EPC requirements come from two pieces of legislation: The Energy Performance of Buildings (England and Wales) Regulations 2012 sets out when you need an EPC, while The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 sets the Minimum Energy Efficiency Standards (MEES) for rental properties.
It's crucial to understand the difference: EPC exemptions mean you don't need a certificate at all, while MEES exemptions mean you still need an EPC but are temporarily exempt from meeting the minimum E rating when renting. Many people confuse the two, which can lead to costly mistakes.
Full EPC Exemptions (No Certificate Required)
The following types of property are completely exempt from needing an EPC:
Places of Worship
Buildings used primarily as places of worship and religious activities are fully exempt. This includes churches, mosques, synagogues, temples, gurdwaras, and meeting houses.
However, if a place of worship contains residential accommodation (such as a vicarage or rectory that's part of the same building), the residential portion may still require an EPC if it's being sold or let separately.
Temporary Buildings (Less Than 2 Years)
Buildings with a planned time of use of two years or less are exempt. This includes temporary site offices, portacabins, show homes with a limited lifespan, and modular structures intended for short-term deployment.
The key test is the intended use period at the time of construction or placement — not how long the building has actually been in use. If a "temporary" structure ends up being used for more than two years, the exemption no longer applies.
Buildings Due for Demolition
Buildings that are subject to a confirmed demolition order, or where the owner can demonstrate that all relevant planning permissions and conservation area consents for demolition have been granted, are exempt.
Simply intending to demolish a building is not enough. You must have the formal approvals in place. If the demolition plans fall through and you subsequently sell or let the building, you'll need an EPC.
Standalone Non-Residential Buildings Under 50m²
Very small standalone buildings that are not dwellings and have a total useful floor area of less than 50 square metres are exempt. This covers small workshops, detached garages, storage buildings, and similar structures.
This exemption does not apply to small residential dwellings. A self-contained studio flat under 50m² still needs an EPC if it's being sold or rented.
Industrial Sites, Workshops, and Non-Residential Agricultural Buildings
Buildings where a large proportion of the internal space is open to the outside or where the main energy use is for industrial processes (not for conditioning the space for human occupants) are exempt. This includes factories, workshops with large open doors, agricultural barns, and similar buildings.
However, if any part of the building is used as office space or for human occupation, that part may need to be assessed separately.
Listed Buildings — The Most Misunderstood Exemption
"My property is listed, so I don't need an EPC"
This is wrong, and it's the most common misconception about EPC exemptions. Listed buildings (Grade I, Grade II*, and Grade II) are not automatically exempt from needing an EPC. If you sell or rent a listed building, you still need a valid Energy Performance Certificate.
Listed buildings are exempt from MEES improvement requirements — not from having an EPC
The exemption for listed buildings relates to the Minimum Energy Efficiency Standards (MEES), not the EPC itself. Under Regulation 25 of the MEES Regulations, landlords of listed properties can claim an exemption from the minimum E rating if making the required energy improvements would "unacceptably alter the character or appearance" of the building.
In practice, this means:
- Selling a listed building: You still need an EPC. No exemption exists for the certificate itself.
- Renting a listed building rated F or G: You can claim a MEES exemption if energy improvements would harm the building's character. You must register this exemption on the PRS Exemptions Register.
- Buildings in a conservation area: Similar rules apply — the exemption is from making improvements, not from having an EPC.
The only scenario where a listed building doesn't need an EPC at all is if it also qualifies under one of the other full exemptions (e.g., it's a place of worship).
For more details about how EPCs affect listed buildings, see the GOV.UK guidance on EPCs for domestic buildings and Historic England's guidance on energy efficiency in historic buildings.
MEES Exemptions for Landlords
The Minimum Energy Efficiency Standards require rental properties in England and Wales to have an EPC rating of at least E. Properties rated F or G cannot be legally let unless the landlord has a registered exemption. Here are the valid MEES exemptions:
All Improvements Made Exemption
If you've made all "relevant energy efficiency improvements" that can be made (or there are none that can be made), and the property still doesn't reach E, you can register this exemption. "Relevant improvements" are those listed in Schedule 4 of the MEES Regulations that are cost-effective within the government's payback criteria.
Validity: 5 years from registration date.
Cost-Effectiveness Exemption (High Cost)
If the cost of bringing the property to an E rating exceeds the current cost cap (£3,500 including VAT for domestic properties), you can register an exemption. You must have spent up to the cap on improvements first, and provide evidence (typically three independent quotes) to show that the remaining improvements exceed the cap.
Validity: 5 years from registration date.
Wall Insulation Exemption
If the only way to reach an E rating is through wall insulation (cavity, external, or internal), and a registered installer or surveyor determines that wall insulation would cause damage to the fabric of the building, you can claim this exemption. This often applies to properties with stone walls, non-standard construction, or buildings in conservation areas.
Validity: 5 years from registration date.
Consent Exemption
If you need consent from a third party to make energy improvements (e.g., planning permission, conservation area consent, or a superior landlord's permission), and that consent has been refused, or was granted with conditions that make the improvements unreasonably expensive, you can register this exemption.
For landlords of leasehold properties, this also applies if the tenant refuses consent for improvements that would affect their unit.
Validity: 5 years from registration date.
Devaluation Exemption
If an independent surveyor (RICS-qualified) provides a written opinion that the required energy improvements would reduce the market value of the property by more than 5%, you can register this exemption. This is relatively rare but may apply where, for example, installing external wall insulation would significantly alter a property's appearance in a way that reduces its appeal.
Validity: 5 years from registration date.
New Landlord Exemption
If you become a landlord of a property that's already let (e.g., by inheriting it or buying it with sitting tenants), and the property is below E, you have a temporary exemption of 6 months to either make improvements or register another exemption. This gives new landlords time to assess the situation.
Validity: 6 months only.
Important for landlords: MEES exemptions must be registered on the PRS Exemptions Register to be valid. Simply meeting the criteria is not enough — if you haven't registered, you're not exempt, and Trading Standards can fine you up to £5,000. Read our full guide on EPC rules for landlords.
Holiday Lets and Short-Term Rentals
The rules around holiday lets are nuanced and frequently misunderstood:
Properties Rented for Less Than 4 Months Per Year
If a holiday property is rented out for fewer than 4 months in total per year, it is exempt from MEES requirements. This means you don't need to meet the minimum E rating to let it. However, you may still need an EPC if the property is marketed through a letting agent or online platform, as they are required to display the EPC rating in advertising.
Properties Rented for 4+ Months Per Year
Holiday lets that are available for 4 or more months per year are subject to the same MEES requirements as standard rental properties. They need an EPC, and that EPC must show a rating of E or above (unless a registered exemption applies).
Short-Term Lets Under 4 Months Consecutive
Short-term lets (e.g., Airbnb-style lettings) where no single tenancy exceeds 4 consecutive months are in a grey area. The government's guidance suggests these may not need an EPC, but this hasn't been definitively tested in enforcement. If you're regularly letting your property on a short-term basis through a platform, having an EPC is advisable to be safe.
Scotland — Different Rules
Scotland has its own EPC regulations. Short-term let legislation in Scotland (introduced in 2022) requires all short-term let properties to have an EPC, regardless of the rental duration. This is stricter than the rules in England and Wales. Check the Scottish Government's EPC guidance if your property is in Scotland.
Rural and Off-Grid Properties
Rural and off-grid properties often have unique energy situations. Here's how exemptions apply:
Off-Grid Heating (Oil, LPG, Solid Fuel)
Properties that aren't connected to the gas grid still need an EPC. There is no exemption for being off-grid. However, these properties often score poorly on EPCs because the RdSAP methodology gives lower scores to oil, LPG, and solid fuel heating systems. For landlords with off-grid F/G rated properties, the MEES exemptions above (particularly the cost-effectiveness and wall insulation exemptions) are often relevant.
Properties Without Mains Electricity
In very rare cases where a property has no mains electricity supply at all, it may be difficult to produce a standard EPC. However, there's no formal exemption for this. Assessors use the RdSAP methodology which can accommodate off-grid scenarios. If you're selling or letting such a property, you'll still need to arrange an EPC assessment.

If you're a landlord who qualifies for a MEES exemption, here's how to register:
- Visit the PRS Exemptions Register: Go to prsregister.beis.gov.uk
- Create an account (or log in if you already have one)
- Select the property and the type of exemption you're claiming
- Upload supporting evidence:
- For cost-effectiveness: three independent quotes showing the cost exceeds the cap
- For wall insulation: a report from a registered installer or surveyor
- For consent: copies of refused planning applications or consent requests
- For devaluation: a written report from a RICS surveyor
- For listed buildings: evidence that improvements would alter the building's character
- Submit the registration. You'll receive confirmation and the exemption will be recorded against the property
Exemption Validity Periods
| Exemption Type | Validity | Can You Renew? |
|---|---|---|
| All improvements made | 5 years | Yes, if still applicable |
| Cost-effectiveness (high cost) | 5 years | Yes, with new evidence |
| Wall insulation damage | 5 years | Yes, with updated report |
| Consent refused | 5 years | Yes, if consent still refused |
| Devaluation | 5 years | Yes, with new survey |
| New landlord | 6 months | No — must improve or get another exemption |
| Full EPC exemptions (places of worship, etc.) | Permanent | N/A — no registration needed |
When a MEES exemption expires, you must either make the necessary improvements to reach band E, or provide fresh evidence and re-register. The exemption does not automatically renew. Failure to act at expiry means you're letting illegally.
Common Myths About EPC Exemptions
"I don't need an EPC because I'm not selling — I'm just remortgaging"
Correct — for now. You don't need an EPC to remortgage. However, some lenders now request the EPC rating as part of their valuation process, particularly for green mortgage products. While it's not a legal requirement, having a current EPC may help your remortgage application.
"My property is too old to have an EPC"
Wrong. There is no age-based exemption. Whether your property was built in 1426 or 2026, if it's being sold or rented, it needs an EPC (unless it qualifies under one of the specific exemptions listed above). The RdSAP methodology has provisions for assessing very old buildings.
"Shared accommodation (HMOs) is exempt"
Wrong. Houses in Multiple Occupation (HMOs) need an EPC for the whole building, and in some cases for individual let rooms. Since October 2008, an EPC has been required when an HMO is rented out. The MHCLG guidance confirms that MEES applies to HMOs.
"A MEES exemption means I never have to improve my property"
Wrong. MEES exemptions last a maximum of 5 years (6 months for new landlords). After expiry, you must either make improvements or provide fresh evidence for a new exemption. The government has also signalled that MEES requirements will tighten (potentially to band C by 2028/2030 for rentals), so relying on permanent exemptions is risky.
Penalties for Getting It Wrong
The consequences of incorrectly claiming an exemption — or failing to have an EPC when required — can be significant:
- Missing EPC (selling): Fine of up to £5,000 from Trading Standards
- Missing EPC (letting): Fine of up to £5,000
- Letting an F/G property without registered exemption: Fine of up to £5,000 (per property, per offence)
- Providing false exemption information: Additional penalties and potential prosecution
Local authority Trading Standards teams enforce these requirements and can inspect the PRS Exemptions Register. Some local authorities are proactive in checking compliance — particularly in areas with large private rented sectors.
