Landlords in England and Wales must have a minimum EPC rating of E before letting a property. Proposals to raise this to C have been delayed, but the E minimum is enforced now, and fines reach up to £30,000. If your rental property sits at F or G, you need to act before your next tenancy or face penalties.
The rules catch out more landlords than you'd expect. We regularly see people who bought a property years ago, never checked the certificate, and only discover the problem when a letting agent flags it during a tenancy renewal. So here's exactly where things stand and what you need to do about it.
What EPC Rating Do Landlords Need in 2026?
E. That's the legal minimum right now.

Since April 2020, every privately rented property in England and Wales has needed an EPC rating of E or above before you can grant a new tenancy or renew an existing one. This applies at the point of letting, not just when a new tenant moves in, so if your current tenant renews their contract and your property is rated F or G, you're technically in breach of the Minimum Energy Efficiency Standards (MEES) regulations.
You've probably heard about plans to raise the minimum to C. The previous government proposed this for 2025, then dropped it. The current government's Warm Homes Plan signals that a C requirement is coming eventually, but there's no confirmed date and no legislation in place yet. For now, E is the floor.
Here's the honest bit: even though C isn't mandatory yet, the direction of travel is obvious. If your property is scraping an E, you're one policy announcement away from non-compliance. Landlords who start improving now will spread the cost over time rather than scrambling when the rules tighten. We've covered the broader policy direction in our Warm Homes Plan guide if you want the full picture.
Which Tenants and Properties Are Affected?
Not every rental property falls under MEES. The rules apply to domestic private rented properties in England and Wales that are legally required to have an EPC. In practice, that covers the vast majority of lets.
But there are exceptions:
Listed buildings where compliance would unacceptably alter their character or appearance
Properties let on tenancies of 6 months or less (though this exemption is narrow and rarely applies to standard ASTs)
Properties let on tenancies of 99 years or more before the regulations came into force
Temporary buildings with a planned time of use of 2 years or less
Social housing follows different rules under a separate regulatory framework, so if you're a private landlord letting through a housing association lease, check which set of regulations applies to your specific arrangement.
One thing that trips people up: holiday lets and Airbnb-style short lets don't currently need an EPC in most cases. But if you switch a property from short-term to an assured shorthold tenancy, you'll need one immediately. And it'll need to be E or above.
How Much Does It Cost to Improve Your EPC Rating?
This is where landlords get nervous. The answer ranges from "barely anything" to "quite a lot," and it depends almost entirely on what's dragging your rating down.
Let's start with the cheap wins.
Loft insulation. If your property has less than 100mm in the loft, topping up to 270mm costs roughly £300 to £600 and typically pushes a rating up by one full band. It's the single best return on investment for EPC improvement, and we've written a detailed breakdown of loft insulation costs and grants separately. For a property sitting at F, this alone might get you to E.
Draught-proofing and lighting. Replacing old halogen bulbs with LEDs and sealing draughts around doors and windows can shift your score by a few points. Cost: under £200 for a typical two-bed. Not glamorous, but sometimes those few points are all you need.
Cavity wall insulation. If your property has unfilled cavity walls, insulation costs around £800 to £1,500 depending on the size of the property. This is a bigger job but usually worth a full band improvement. Our cavity wall insulation guide covers the process and what to expect.
Now the expensive end.
Solid wall insulation, whether internal or external, runs from £4,000 to £14,000 or more. New windows can cost £3,000 to £7,000 for a full house. A heat pump installation starts around £7,000 after grants. These are the upgrades that would push a D to a C, which is why the proposed C minimum worried so many landlords.
Grants Landlords Can Use to Meet EPC Standards in 2026
Right, so can you get any help paying for this?
Yes, but the options for landlords specifically are more limited than for owner-occupiers. Most government grant schemes are designed for homeowners or low-income tenants, not landlords. That said, there are routes worth exploring.
ECO4 is the big one. It funds insulation, heating upgrades, and other measures for households on qualifying benefits. The key detail for landlords: ECO4 eligibility is based on the tenant's circumstances, not yours. If your tenant receives Universal Credit, Pension Credit, Child Tax Credit, or certain other benefits, the property may qualify for fully funded upgrades under ECO4. The scheme runs until December 2026, so there's still time, but the window is narrowing.
The Warm Homes: Local Grant operates through local authorities and varies enormously by area. Some councils include privately rented properties; others don't. Bristol, for example, has been more generous with landlord-eligible funding than many other areas. You'll need to check with your specific local authority, and our Warm Homes: Local Grant guide explains how the scheme works across different regions.
The Boiler Upgrade Scheme offers £7,500 towards an air source heat pump or ground source heat pump. This one is available to landlords directly, which makes it unusual. If your property still runs on an oil boiler or an old gas system and you're looking at a longer-term investment, this could make a heat pump financially viable. The scheme runs until March 2028.
The Great British Insulation Scheme, which previously offered up to £3,000 for insulation measures, closed in March 2026. It's no longer available, but if you had work done under it, the improvements will still count on your EPC.
Honestly, the grant situation for landlords is patchier than for homeowners. The government's position has broadly been that landlords should fund improvements themselves since they benefit from the asset value increase. That's frustrating if you're a small landlord with one or two properties and tight margins, but it's the reality.
What Happens If You Do Not Meet the Minimum EPC Requirements?
Fines. Potentially large ones.
Local authority trading standards teams enforce MEES. If you let a property with an F or G rating without a valid exemption, you can be fined:
Up to £5,000 for renting a non-compliant property for less than 3 months
Up to £30,000 for renting a non-compliant property for 3 months or more
These are per-property fines. If you own three non-compliant flats, that's three separate penalties.
Enforcement has been inconsistent, and that's led some landlords to assume the rules aren't really enforced. This is a gamble. Local authorities have been increasing enforcement activity, and the penalties are published on a public register, which means your non-compliance becomes a matter of public record. For landlords with portfolios, reputational damage can matter as much as the fine itself.
There is an exemption route. If you can demonstrate that all cost-effective improvements have been made (defined as measures that pay for themselves through energy savings within 7 years) and the property still doesn't reach E, you can register a "high cost" exemption on the PRS Exemptions Register. This exemption lasts 5 years. But you need to actually register it, with evidence. Simply claiming you can't afford improvements isn't enough.
A quick aside: the 7-year payback test is interesting because it was designed when energy prices were lower. With current gas and electricity costs, more measures now pass the payback threshold than when the rules were written. So an exemption that might have been valid in 2019 may no longer hold up. Worth rechecking if you registered one a few years ago.
How to Get Your Property Assessed and Improve Its Rating
So you need to act. Here's the practical sequence.
First, check whether your property already has a valid EPC. Every EPC lasts 10 years, and you can look yours up for free on the government's EPC register. If your certificate is from 2016 or later, it's still valid. If it's older, or if you've made improvements since the last assessment, you'll want a new one.
Getting a new EPC costs between £50 and £120 depending on your area and property size. We've broken down exactly what an EPC costs and what affects the price in a separate guide. The assessment itself takes about 45 minutes for a typical property. The assessor checks insulation, heating, windows, lighting, and hot water systems, then generates a rating and a recommendations report.
That recommendations report is gold. It tells you exactly which upgrades would improve your rating and by how much. Don't ignore it.
Once you know your current rating and the recommended improvements, prioritise by cost-effectiveness. Loft insulation and cavity wall insulation almost always come first. Then heating controls and boiler upgrades. Then windows and more expensive measures. You don't need to do everything on the list. You just need to reach E.
After completing improvements, get a new EPC to confirm your updated rating. Keep records of all work done, including invoices and installer certifications, in case your local authority ever requests evidence of compliance.
One thing we'd recommend: don't wait until a tenancy renewal forces your hand. EPCs take a few weeks to arrange, improvements take time to schedule, and if you're relying on a grant like ECO4, the application and installation process can take months. Start now, even if your current tenancy doesn't expire for a while.

Frequently asked questions
Do I need an EPC if my property is already tenanted?
Yes. The MEES regulations apply to existing tenancies, not just new lets. Since April 2020, all private rented properties in England and Wales need an EPC rating of E or above, including where a tenant is already in place. If your property is rated F or G and you haven't registered a valid exemption, you're technically non-compliant right now.
Can I pass the cost of EPC improvements on to my tenant?
No.
What if my property is a listed building?
Listed buildings are exempt from MEES if the required energy improvements would unacceptably alter the property's character or appearance. But this isn't a blanket exemption. You'd need to demonstrate that specific measures can't be carried out, not simply that the building is listed. Some improvements, like loft insulation or a modern boiler, can often be installed in listed properties without affecting their character. Get advice from your local conservation officer before assuming you're exempt.
Will the minimum EPC requirement for landlords increase to C?
Almost certainly, eventually. The previous government proposed a C minimum by 2025 but dropped it. The current government's Warm Homes Plan signals a C requirement is coming, but no date has been confirmed and no legislation has been introduced. Our view: plan for it. If your property is at D or E, start thinking about what it would take to reach C, because when the requirement does land, there'll be a rush for installers and assessors.
How long does an EPC last?
10 years from the date of issue. But if you've made improvements since your last assessment, it's worth getting a new one early. Your current certificate might show an E when the property would now score a D after insulation work, which matters if future regulations raise the minimum.
