Landlord EPC Exemptions Explained

Exemptions are the most misunderstood corner of landlord EPC compliance. Some landlords assume an old or solid-wall property automatically qualifies; others don’t realise exemptions exist at all and overspend trying to reach a standard they were never required to hit. The truth sits in between. There is a formal route that lets a genuinely unimprovable home be let lawfully while sub-standard, but it is evidenced, time-limited and registered per property. This guide sets out the six exemption types, the cost cap that underpins most of them, and how to register, honestly framed as a backstop rather than a strategy.

First, what an exemption actually does

The minimum EPC standard to let a home in England or Wales is currently E. It has been unlawful to grant a new tenancy below E since 1 April 2018, and unlawful to continue letting an existing tenancy below E since 1 April 2020, unless you have registered a valid exemption. An exemption is not funding and it does not improve the property. It is a legal shield that lets you continue letting a home that falls below the standard, where you can show it genuinely cannot be brought up to standard within the rules. The full basis is in the domestic MEES landlord guidance on GOV.UK{rel=“noopener”}.

Crucially, an exemption is not a way to dodge straightforward improvements. If a modest fabric-first package would lift your property over the line within the cost cap, you are expected to do it. The exemptions exist for homes where that genuinely is not possible.

The £3,500 cost cap sits behind everything

Most of the exemptions turn on money, so understand the cap first. Under the current EPC E standard you are not required to spend more than £3,500 including VAT trying to reach E. If the cheapest measure that would get you there costs more than that, you are not obliged to do it, and the “high cost” exemption applies. For the proposed EPC C standard a higher cap of £10,000 has been proposed, subject to legislation, with exemptions proposed to run ten years rather than five. Bear in mind EPC C by 2030 remains a proposal, not yet law.

The six exemption types

Each of these is registered per property on the PRS Exemptions Register, and each requires specific evidence.

Exemption	When it applies	Evidence needed	Typical length
All relevant improvements made	You’ve done every relevant measure within the cost cap and the property is still below the standard	Records of the works and the resulting EPC	5 years
High cost	The cheapest relevant measure exceeds the £3,500 cap	Three installer quotes showing the cost	5 years
Wall insulation	Independent expert advice shows wall insulation would damage the property	Written expert opinion	5 years
Third-party consent	A freeholder, planning authority, tenant or lender refuses required consent	Evidence of the refusal	5 years (re-try when consent might be given)
Property devaluation	An independent surveyor confirms works would reduce the value by more than 5%	RICS surveyor’s report	5 years
New landlord (temporary)	You’ve recently and unexpectedly become a landlord	The circumstances qualifying you	6 months

A few honest notes on the ones landlords misread:

• Wall insulation is not “my walls are solid, so I’m exempt”. It requires independent expert advice that insulation would damage the specific property, a real risk on older solid walls prone to damp, but an assessed judgement, not an assumption. See how to improve a solid-wall terrace’s EPC for when this genuinely bites.
• Third-party consent is the one that most often applies to flats, where a freeholder or management company refuses communal works. Our buy-to-let flat EPC page covers the leasehold constraint in detail.
• Listed and heritage properties are not automatically exempt. A genuinely listed building can be exempt from needing an EPC only where improvement works would unacceptably alter its character, and conservation-area status is not the same thing. See our listed and heritage rental EPC page.

How to register an exemption

Registration is done by the landlord (or agent) on the government’s PRS Exemptions Register. In practice the process is:

1. Confirm the property genuinely qualifies. Get a current EPC and, for cost-based exemptions, the installer quotes or expert reports the register will ask you to hold. A weak assessment done without proper survey evidence can wrongly show a fail, so start with an accredited assessment.
2. Gather the evidence. The register asks you to declare the exemption type and confirm the supporting evidence. Keep it on file; you may be asked to produce it.
3. Register per property. Each home needs its own exemption entry, and each entry is tied to that address. A portfolio of unimprovable homes means multiple registrations.
4. Diarise the expiry. Most exemptions last five years, after which you must try again to improve the property, so an exemption is a pause, not a permanent pass.

Why it’s a backstop, not a strategy

It is tempting to see exemptions as the cheap route: register one and forget the problem. That thinking usually costs more in the long run for three reasons.

First, most exemptions expire after five years, so you face the same decision again, and the cost cap or the standard may have risen in the meantime. Second, an exemption does nothing for tenant appeal or running costs — weak-EPC homes let more slowly and tenants increasingly filter on efficiency. Third, and most importantly, for the majority of homes a modest fabric-first package within the cost cap is cheaper and lower-risk than relying on repeated exemptions. Loft insulation, heating controls, draught-proofing and LED lighting lift most borderline properties to a lettable rating for a few hundred to a few thousand pounds — well inside the cap. Our cost guide and how much it costs to reach EPC C set out the numbers.

The rational sequence is: try to improve first, register an exemption only where the property genuinely cannot be brought up to standard within the rules, and treat every exemption as a five-year reminder to revisit.

Where exemptions fit against the penalties

Exemptions matter because the alternative is expensive. Letting below the standard without a valid exemption exposes you to penalties of up to £5,000 per property, enforced by your local authority, which can also publish the breach — see landlord EPC penalties explained. A properly registered exemption removes that exposure for a genuinely unimprovable home. An assumed, un-registered “exemption” removes nothing.

For local context on how councils enforce, see our pages on landlord EPCs in Manchester, Birmingham and London, and to understand the standards behind all of this, read EPC E vs EPC C for landlords. Common misconceptions are also covered in our landlord EPC myths page and the full FAQs.

The honest bottom line

Exemptions are a legitimate and important part of the regime, but they are a shield for genuinely unimprovable homes, not a shortcut for stock you simply haven’t improved. Confirm you qualify with real evidence, register per property, diarise the expiry, and for most homes take the cheaper fabric-first route instead.
