EPC Exemption 2026: When You Can Skip the Rating

What Is an EPC Exemption and Who Qualifies?

An EPC exemption is a formal recognition that your property either doesn't legally need an EPC, or can be let below the minimum E rating without breaking the law. There's a difference, and it matters.

The first category is properties that fall outside EPC rules entirely. Listed buildings where compliance would unacceptably alter their character. Places of worship. Industrial sites with low energy demand. Temporary buildings used for less than two years. Holiday lets occupied under four months a year. These don't need an EPC at all.

The second category is more common, and it's where most landlords end up. Your property has an EPC, it's rated F or G, but you've registered an exemption that lets you continue letting it lawfully. See our guide on EPC ratings explained for more detail. The most-used exemption here is the £3,500 cost cap: if you've spent £3,500 (inclusive of VAT) on energy efficiency upgrades and still can't reach band E, you can register a five-year exemption.

There are others. The "all relevant improvements made" exemption, where every recommended upgrade on your EPC has been carried out but the rating still won't budge. The "wall insulation" exemption, for solid wall properties where a chartered surveyor has confirmed insulation would damage the structure. The "third-party consent" exemption, where a tenant, lender, or freeholder has refused permission for the work.

None of these are automatic. You register them. We'll come to how.

Which Properties Are Most Likely to Be Exempt?

Listed buildings, solid wall Victorian terraces, and small rural cottages are the three property types we see exempt most often. Each for different reasons.

Listed buildings are the headline case. If you own a Grade II listed cottage in the Cotswolds, the chances of getting it from F to E without altering its character are slim. Double glazing is out. External wall insulation is out. Sometimes even internal wall insulation is refused by the local conservation officer. Historic England has confirmed in writing that listed status itself doesn't grant automatic EPC exemption, the test is whether compliance would "unacceptably alter character or appearance." In practice, for most pre-1919 listed homes, it does.

Solid wall properties are the next big group. Roughly 8 million UK homes have solid walls, and getting them above band E without wall insulation is genuinely hard. If a chartered surveyor reports that insulation would cause damp or structural damage, you can register an exemption on that specific measure. See our guide on wall insulation for more detail. You still have to do everything else, like loft insulation, draught-proofing, and a better boiler.

Then there's the cost-cap group. These are properties where the £3,500 spend has been hit and the rating is still F. We see this a lot in stone-built cottages in Cornwall, Devon, and the Welsh borders. The upgrades that would actually work, such as external insulation or a heat pump, run to £15,000 or more.

A quick aside: the £3,500 cap is per property, not per landlord, and it includes any spend by previous owners on energy efficiency measures within the past seven years. That catches people out.

How EPC Exemptions Affect Your Eligibility for Energy Grants in 2026

Most exemptions don't block you from grants. This is the bit landlords get wrong most often.

If you've registered a cost-cap exemption, you can still apply for ECO4, the Boiler Upgrade Scheme, and the Warm Homes: Local Grant. The exemption is about your legal position as a landlord. It doesn't change whether the property qualifies for funding. In fact, exempt properties often have the worst ratings, which is exactly what these schemes target.

There are some catches.

ECO4 prioritises homes rated D to G, so an exempt F-rated property is high priority. But the tenant has to be on a qualifying benefit, and the work has to deliver a measurable EPC improvement. If your exemption is registered because no improvements would shift the rating, ECO4 funding might be limited to specific measures only.

The Boiler Upgrade Scheme doesn't care about EPC band at all for the £7,500 air source heat pump grant. It cares about having loft and cavity wall insulation in place (where possible), and a property suitable for a heat pump. So an exempt property in a listed cottage might struggle, but an exempt property in an uninsulated 1960s bungalow won't.

The Warm Homes: Local Grant runs through local councils and varies wildly. Cornwall's scheme is generous. Cambridge's is targeted at specific postcodes. Worth checking yours directly.

Here's the honest bit. If you've registered an exemption because upgrades aren't physically possible, grants won't change that. But if you've registered a cost-cap exemption because YOU couldn't afford the upgrades, a grant might cover what you couldn't. That's worth looking into.

How to Register an Exemption on the PRS Exemptions Register

You register exemptions yourself, online, on the government's PRS Exemptions Register. It's not done by your EPC assessor or your letting agent.

The process is free. You'll need:

• Your property address and EPC number
• Evidence supporting the exemption (invoices for the £3,500 cap, surveyor's report for wall insulation, consent refusal letters)
• The specific exemption category you're claiming
• Photographs in some cases

For the cost-cap exemption, the evidence threshold is real. You can't just say you've spent £3,500. You need three quotes showing the cheapest route to band E would exceed that, plus invoices for what you've actually done. Local authorities can request this evidence for up to seven years after registration.

The registration takes around 20 minutes if your evidence is ready. Approval is usually immediate, the system doesn't manually review most applications upfront. But that's where landlords get complacent. Trading Standards officers do spot-check the register, and a fraudulent or unsupported exemption can land you with a £5,000 penalty separate from the standard MEES (Minimum Energy Efficiency Standard) fines.

A quick warning. Don't let a letting agent or a third party register on your behalf without seeing the documents. We've seen agents tick boxes without proper evidence to avoid having to chase landlords for upgrade work, and the legal liability sits with you, not them.

What Happens When Your Exemption Expires?

Most exemptions last five years, then you have to re-assess.

When the five years are up, you're back at square one. The exemption doesn't auto-renew. You need to either:

1. Upgrade the property to band E or above, or
2. Register a fresh exemption with new evidence, or
3. Stop letting the property

The critical point is the rules around upgrades may have changed by then. The government's been signalling for years that the minimum standard will rise to band C for new tenancies, and band C for all tenancies by 2030. The exact dates have shifted more than once, and as of mid-2026 the band C deadline still hasn't been written into law. But it's coming.

So a cost-cap exemption registered today, expiring in 2031, lands right in the middle of whatever the new regime turns out to be. The £3,500 cap might rise to £10,000. The minimum rating might be C. Your exemption might no longer be valid against the new standard.

If you're a landlord registering an exemption now, plan for two scenarios. Either the rules tighten and you'll need to spend more in 2031, or they stay the same and you re-register easily. Either way, don't treat the exemption as permanent.

One more thing worth knowing. Some exemptions are tied to the landlord, not the property. The "new landlord" exemption gives you six months to get up to standard after first letting a property. So if you sell up, the new owner can't inherit your exemption, they have to register their own or upgrade.

EPC Exemptions vs Low EPC Ratings: Which Situation Are You In?

Having a low rating and being exempt are two very different positions, and the route forward depends on which one applies.

If you're rated F or G and you haven't registered an exemption, you're letting unlawfully. The MEES penalty regime starts at £2,000 per property for non-compliance under three months, rising to £4,000 for longer, and stacking up to £30,000 in serious cases. Trading Standards enforces this, and they've been more active since 2024.

If you're rated F or G with a valid registered exemption, you're letting lawfully but on borrowed time. The exemption expires. You should be planning the upgrade work now, even if you don't do it yet.

If you're rated D or E, you're fine for now under current rules. But if the rumoured band C minimum lands, you'll be in the same position as today's F-rated landlords. We'd suggest starting with a Retrofit Assessment to understand the cheapest path to C.

If you're rated A, B, or C, you've got nothing to worry about for the foreseeable future. Most landlords aren't here. About a quarter of the private rented sector sits at D, and roughly 8% is still F or G.

The single most useful thing you can do right now, whatever your rating, is check what grants you'd qualify for. The eligibility check takes two minutes and covers all the active 2026 schemes including ECO4 (for tenants on benefits), the Boiler Upgrade Scheme (for heating upgrades), and your local Warm Homes scheme.

Not every property gets to band E or C economically. But more do than landlords assume, especially with grant funding factored in. Get the numbers before you register an exemption you don't need.
