EPC Requirements for Landlords UK

An Energy Performance Certificate (EPC) rates how energy efficient a property is, from A (most efficient) to G (least efficient), and every rental property in England and Wales needs a valid one before it can be marketed or let. For most landlords, the practical question is not whether they need an EPC at all, but whether their current rating meets the legal minimum, and what changes are coming that might affect that minimum.

As of August 2026, the minimum standard for most private rentals is band E. Properties rated F or G cannot legally be let unless a valid exemption is registered. The government has also proposed raising that minimum to band C for new tenancies, though this is not yet confirmed law, so this guide separates what is settled from what is still proposed.

Current minimum standard

The Minimum Energy Efficiency Standards (MEES) regulations set band E as the lowest EPC rating a private rented property in England or Wales can have and still be legally let, subject to exemptions. This has applied to new tenancies since 1 April 2018 and to all existing tenancies since 1 April 2020, so by now it covers essentially every private letting, including relets and renewals.

If your property is rated F or G and no valid exemption is registered, you should not grant a new tenancy, and continuing to let under an existing tenancy without an exemption also breaches the regulations. Local authorities can issue penalty notices for non-compliance, and the specific penalty amounts are set out on GOV.UK rather than repeated here, since they can be revised. The safest approach if you are below band E is to treat it as urgent: either carry out improvements to reach band E, or register a valid exemption if one genuinely applies to your situation.

An EPC is valid for 10 years from the date it was issued, so check the expiry date on your current certificate even if you believe the rating itself is comfortably above the minimum. A property cannot be marketed to let with an expired EPC, regardless of what the last recorded rating was.

As a worked example, a two-bedroom terraced house with a rating of F, gas central heating and no loft insulation might move to band E simply by adding loft insulation and switching to LED lighting, both relatively low-cost measures. A detached property with solid walls and an old boiler is a different case: it may need a new boiler and either solid wall insulation or a heat pump to close the same gap, which is a considerably larger project. This is why an EPC recommendation report, rather than a general rule of thumb, matters for planning which improvements to prioritise.

Proposed future changes

The government has, at various points, consulted on and proposed raising the minimum standard for private rentals from band E to band C, with the change intended to apply to new tenancies first and then extend to all tenancies. These proposals have moved through several rounds of consultation and the exact timetable has shifted more than once, so treat any specific date you see quoted elsewhere with caution.

Because this policy area is actively evolving, do not plan improvement works around a specific deadline you have seen quoted without checking GOV.UK for the current position first. What is worth doing regardless of the exact commencement date is building general efficiency improvements into your maintenance plan, since a band C target, if and when it is confirmed, will require most sub-C properties to make changes eventually. Landlords who improve fabric efficiency (insulation, glazing) and heating systems opportunistically, for example during a void period or a renovation, are better placed than those who wait for a firm deadline before acting.

Exemptions

If your property is below band E, you may be able to register a valid exemption on the PRS Exemptions Register rather than carrying out immediate improvement works. Common exemption categories include:

• All relevant improvements made. You have carried out every cost-effective improvement available under the scheme's funding rules and the property is still below band E.
• High cost exemption. The cost of the improvements needed would exceed the funding cap set out under the regulations.
• Third-party consent refused. A tenant, freeholder, planning authority or similar third party has refused consent needed to carry out the improvement.
• Devaluation exemption. An independent surveyor confirms that a specific improvement would reduce the property's market value by more than a set percentage.
• New landlord exemption. A grace period applies if you have just become the landlord, for example through inheritance or purchase, giving you time before the standard applies.
• Listed buildings. Some listed or officially protected buildings are exempt where the improvement would unacceptably alter the character of the building.

Exemptions must be registered, they are not automatic just because a condition technically applies. Each exemption also typically lasts five years, after which you need to reassess and re-register if it still applies, or carry out improvements in the meantime. Registering an exemption you do not actually qualify for does not protect you if a local authority investigates, so keep evidence (quotes, refusal letters, surveyor reports) that supports whichever exemption you use.

Before assuming an exemption is your only option, get at least one or two quotes for the improvement work first. Landlords sometimes assume a high cost exemption applies without actually pricing the work, only to find a specific measure, such as loft insulation, is well within typical funding caps and would have been quicker to complete than to document an exemption for.

Improvement options

If your property is below band E, or you want to get ahead of a possible band C requirement, the improvements that typically move an EPC rating the most, roughly in order of common cost-effectiveness, are:

• Loft insulation and cavity wall insulation, where the property has cavity walls and does not already have it.
• Upgrading to LED lighting throughout, which is inexpensive relative to its effect on the rating.
• Improving heating controls, such as adding thermostatic radiator valves and a modern programmable thermostat.
• Replacing an old, inefficient boiler with a more efficient modern one.
• Double or secondary glazing, where the property still has single glazing.
• Solid wall insulation or a heat pump, which cost considerably more but can move an older, harder-to-treat property by several bands.

Not every improvement suits every property, particularly period properties where solid wall insulation can be disruptive and expensive relative to the EPC benefit. Get an EPC assessor's recommendation report alongside your current certificate, since it lists property-specific improvements in the order the software estimates they will help, which is a more useful starting point than a generic checklist. See our guide on improving your EPC rating for a closer look at which upgrades tend to offer the best return for rental properties specifically, and our landlord certificates checklist for how EPCs fit alongside your other compliance documents.

How Property HQ helps

Property HQ tracks your EPC expiry dates and current ratings alongside gas safety, EICR and licensing certificates in one place, so a 10-year-old EPC does not slip past its renewal date unnoticed. If you are weighing up improvement works against an exemption, having your certificate history and property details in one record makes that decision easier to plan around.
