A Guide to EPC Exemption Rules for Property Owners

An EPC is usually a straightforward requirement when selling or letting a property, but exemptions can create uncertainty at exactly the point you need clarity. This guide to EPC exemption rules explains when a property may be exempt, why evidence matters, and the crucial difference between an EPC exemption and a MEES exemption.

For most owners, landlords and agents, the practical starting point is simple: do not assume a building is exempt because it is old, listed, small or difficult to improve. Exemptions are limited, fact-specific and, in some cases, need supporting records. Getting this wrong can delay marketing, a tenancy or a transaction.

When is an EPC normally required?

An Energy Performance Certificate is generally required when a building is constructed, sold or let. It gives the property an energy rating from A to G and includes recommendations for improvement. In practice, sellers need one before marketing a home, while landlords need a valid EPC before granting most new tenancies.

The requirement applies to both domestic and commercial buildings, although the rules and documentation can differ. An EPC remains valid for 10 years unless a newer certificate has been commissioned.

There are specific exemptions, but they relate to the nature and use of the building rather than the owner’s preference. If a property is not clearly within an exemption, arranging an EPC is normally the safest and quickest route to compliance.

EPC exemption rules: the main categories

The following exemptions are the ones most commonly relevant to property owners. They should be assessed carefully against the individual building and its intended use.

Listed buildings and protected buildings

A listed building is not automatically exempt from needing an EPC. This is one of the most common misunderstandings.

The exemption may apply where compliance with minimum energy performance requirements would unacceptably alter the building’s character or appearance. That can be relevant to historic fabric, original windows, protected façades or other features where energy improvements would conflict with heritage controls.

However, many listed properties can still have an EPC carried out without making any alterations at all. The certificate is an assessment of the property as it stands. If you are selling or letting a listed house, cottage or flat, obtain advice before deciding that no EPC is required. Planning restrictions, the listing description and the realistic scope for improvements all matter.

Temporary buildings

Buildings intended to be used for two years or less may be exempt. This can include genuinely temporary site accommodation or short-term structures, provided their intended lifespan is clear.

A building does not become temporary simply because an owner plans to sell it, redevelop it or use it for a short period. The construction and intended use need to support the exemption.

Small detached buildings

A detached building with a total useful floor area of less than 50 square metres may be exempt. The word “detached” is significant. A small flat, shop unit or annex attached to another building will not normally qualify on this basis.

It is also important to use the correct measure. The exemption refers to useful floor area, not an estate agent’s approximate marketing measurement or the external footprint of the building.

Low-energy-demand buildings

Some buildings designed for low energy demand can be exempt. Typical examples may include certain unheated storage buildings, agricultural buildings, workshops or industrial premises where the energy used to condition the indoor environment is minimal.

This exemption is not based solely on a building being commercial or lightly used. A heated workshop, office space within a warehouse, converted barn or unit with staff facilities may still require an EPC. The actual building services and occupation are central to the decision.

Places of worship

Buildings used as places of worship and for religious activities can be exempt. Where a site includes halls, offices, meeting rooms or residential accommodation, each part may need separate consideration depending on its use and layout.

Buildings due for demolition

A building may be exempt where it is being sold or let with a view to demolition, but strict conditions apply. Typically, the relevant planning permission, conservation area consent or listed building consent must be in place, along with evidence that the building is to be demolished.

An intention to redevelop is not enough. Until the necessary permissions and documentation are available, an EPC may still be required for marketing or letting.

EPC exemptions are not the same as MEES exemptions

Landlords often use “EPC exemption” to mean an exemption from the Minimum Energy Efficiency Standards, known as MEES. These are separate issues.

An EPC exemption means that the building may not need an EPC at all. A MEES exemption means that a private rented property has an EPC but may be allowed to be let despite not meeting the minimum rating required by the relevant regulations.

For most privately rented homes in England and Wales, a property needs an EPC rating of E or above before it can be let, unless a valid exemption has been registered. Commercial landlords also need to consider the non-domestic MEES rules.

A low EPC rating does not create an automatic MEES exemption. Landlords must usually take all relevant cost-effective improvements first, or show why a particular exemption applies.

Common MEES exemptions for landlords

MEES exemptions are time-limited and must be recorded on the appropriate PRS Exemptions Register before they can be relied upon. In many cases, an exemption lasts for five years, after which the position must be reviewed and, if still applicable, registered again.

The most common situations include where all relevant energy-efficiency improvements have been made and the property remains below the required rating; where a recommended measure does not meet the required seven-year payback test; where third-party consent cannot be obtained; or where an independent report confirms that a measure would reduce the property’s value by more than 5%.

There can also be a temporary exemption for a new landlord who has recently become responsible for a property, for example through inheritance, purchase or a lease event. This gives limited time to bring the property into compliance or register a longer-term exemption. It should not be treated as a permanent solution.

The evidence required depends on the exemption claimed. It may include a current EPC, quotations, professional reports, correspondence showing consent was refused, or reports from suitably qualified experts. Keep records organised. Local authorities can request evidence and may issue penalties where a property is let in breach of MEES.

How to check whether your property is exempt

Start by confirming the building’s use, size and physical arrangement. A detached garden building, a listed town-centre property and a commercial unit with low occupancy can all look exempt at first glance, yet fall outside the rules once the details are checked.

Next, separate the EPC question from the letting question. If you are a landlord, ask both: does this building need an EPC, and if it has a rating below E, can it legally be let? These are not interchangeable decisions.

Where an exemption depends on heritage status, demolition plans, low energy demand or a MEES improvement test, retain clear supporting documents. A verbal opinion, an old survey or an assumption based on a neighbouring property is unlikely to be enough.

For mixed-use properties, converted buildings and blocks with shared services, it is particularly worthwhile to obtain assessor-led advice early. The correct EPC arrangement may depend on whether parts of the building are self-contained, separately let or served by common heating and ventilation systems.

Avoid delays before marketing or letting

The most efficient approach is to check the position before photographs are taken, a letting advert goes live or contracts are prepared. If an EPC is required, a prompt assessment avoids last-minute compliance issues and gives you a clear rating to work from. If improvements are needed, the recommendations can also help you prioritise measures that are realistic for the property.

For landlords, an up-to-date EPC is useful beyond basic compliance. It can highlight insulation, heating and lighting improvements that may reduce running costs, support tenant demand and improve the property’s long-term resilience against changing standards.

Rules can differ across Great Britain and may change over time, so a practical assessment of the specific property is always better than relying on general assumptions. If you are unsure whether an exemption applies, arranging professional EPC advice before you market or let can protect your timescales and give you a clear, defensible next step.
