EPC Exemptions 2030: When You Don’t Have to Reach Band C

The October 2030 EPC Band C deadline is coming, and if you own rental property you already know the stakes: a potential £30,000 fine per property for non-compliance. But what if your property genuinely cannot reach Band C? The government has built a limited set of exemptions into the regulations — and understanding them now could save you from panic-spending later.

A word of caution before we go any further: most landlords will not qualify for an exemption. The criteria are deliberately narrow, and enforcement bodies will scrutinise claims carefully. Exemptions are a safety valve, not a loophole. If there is any realistic path to Band C for your property, you should be pursuing it.

The cost cap exemption

This is the exemption most landlords will encounter. Under the proposed rules, you are required to spend up to £10,000 per property on qualifying energy efficiency improvements to reach Band C. If you have spent that amount and your property still falls short, you can register for an exemption.

The critical point is that you must have actually spent the money on qualifying improvements. You cannot simply obtain quotes showing it would cost more than £10,000 and then claim an exemption without doing any work. The cap requires real expenditure, documented with invoices and certificates from qualified installers.

For a full breakdown of how the cap works, what qualifies as a “qualifying improvement,” and the retroactive start date, see our dedicated guide: The £10,000 EPC Cost Cap Explained.

All improvements made exemption

This exemption applies where every reasonable energy efficiency measure has been installed in the property but it still cannot reach Band C. “Reasonable” here means measures that are technically feasible and appropriate for the property type — not measures that would require demolishing or fundamentally re-engineering the building.

In practice, this exemption most commonly applies to solid-wall pre-war properties where:

• Loft insulation has been installed to the maximum practical depth
• Internal or external wall insulation has been fitted (or is not feasible)
• Double or triple glazing has been installed
• A modern condensing boiler or heat pump is in place
• Draught-proofing and other low-cost measures have been completed

If all of that has been done and the SAP assessment still returns a score below 69 (the Band C threshold), you may register an exemption. You will need evidence — the EPC itself, plus installer certificates or photographs confirming each measure.

Listed buildings and conservation areas

Heritage properties present a genuine compliance challenge. If your property is a listed building (Grade I, II* or II) or sits within a conservation area, there may be legal restrictions on the types of improvement you can carry out. Common restrictions include:

• External wall insulation: Almost always refused on listed buildings because it alters the external appearance
• Replacement windows: Listed building consent may require like-for-like timber frames rather than modern uPVC double glazing
• Solar panels: May be refused in conservation areas if visible from the street
• Roof insulation: Some historic roof structures cannot accept standard insulation without risk of moisture damage

To claim this exemption, you need written evidence that the relevant authority (the local planning department or Historic England) has refused consent for the improvement, or that the improvement would unacceptably alter the character of the building. A general statement that “it’s a listed building” is not sufficient — you must show that specific measures were considered and rejected.

Consent refused by third parties

Sometimes the barrier to compliance is not the building itself but someone else’s refusal to cooperate. Two common scenarios:

Freeholder or superior landlord refuses consent

If you hold a leasehold interest and the freeholder will not grant permission for improvement works (for example, external wall insulation on a block of flats), you can register an exemption. You will need written evidence of your request and their refusal. A verbal “no” is not enough — put everything in writing.

Tenant refuses access

If a sitting tenant refuses to allow improvement works to be carried out, this can also form the basis of an exemption. Again, you need written evidence: a formal request to the tenant (ideally sent by recorded delivery) and their written refusal. Note that you cannot use this exemption if the property is empty between tenancies — that is precisely when you should be doing the works.

New landlord exemption

If you have recently acquired a rental property (through purchase or inheritance), you are granted a six-month grace period from the date of acquisition to bring the property up to Band C. This recognises that new owners need time to assess the property, obtain quotes, and schedule works.

The grace period is not an exemption from the requirement — it is a temporary deferral. After six months, you must either have a valid Band C EPC or have registered one of the other exemptions. If you are buying property close to the October 2030 deadline, factor compliance costs into your acquisition budget from the outset.

How to register an exemption

Exemptions are registered on the PRS Exemptions Register, maintained by the government. The process involves:

• Creating an account on the PRS Exemptions Register
• Identifying the property by its address and EPC reference
• Selecting the relevant exemption category
• Uploading supporting evidence (invoices, refusal letters, listed building consent decisions, EPC reports)
• Submitting the application for review

Once registered, the exemption is valid for five years. After that, you must either re-register (if the circumstances still apply) or bring the property up to standard. Local authorities have the power to review and challenge exemptions, so ensure your evidence is thorough and well-documented.

What an exemption does NOT protect you from

There are several common misconceptions about what an exemption actually means. Even with a valid exemption on the register:

• You still need a valid EPC. An exemption from the Band C minimum does not exempt you from having an in-date Energy Performance Certificate. Every property marketed for rent must have an EPC that is less than 10 years old.
• You cannot re-let without a valid EPC. If your current EPC has expired, you must commission a new one before marketing the property or entering into a new tenancy agreement.
• Tenants can still request improvements. Under separate regulations, tenants have the right to request energy efficiency improvements. An exemption on the PRS register does not override this right.
• The exemption can be challenged. Local authority enforcement officers can review your exemption and request additional evidence. If they find the exemption was registered without proper grounds, it can be revoked and penalties applied.

For most landlords, the smartest move is to start improvement works now rather than bank on an exemption. With the £10,000 cost cap backdated to October 2025, every pound you spend from now counts. See our guide on EPC Band C requirements for landlords for a step-by-step compliance plan.
