Energy Performance Certificates (EPCs) have long been a core part of property letting in the UK. They indicate how energy-efficient a home is, a rating that directly affects heating costs, sustainability, and even rental value.
But 2026 is shaping up to be a landmark year for landlords. The government is expected to introduce a new EPC framework that will reshape how efficiency is measured and reported. Landlords who prepare early can protect their rental income and property value, whilst those who ignore these updates may face higher costs or compliance issues later.
What Is an EPC?
An Energy Performance Certificate (EPC) measures a property's energy efficiency, grading it from A (most efficient) to G (least efficient). Every rental property in England and Wales must have a valid EPC before it can be marketed or let.
EPCs do more than satisfy legal requirements; they influence tenant attraction, energy bills, and marketability. As more renters look for eco-friendly homes, properties with higher EPC ratings often stand out and let faster.
Current EPC Requirements for Rental Properties
Under the Minimum Energy Efficiency Standards (MEES), rental properties must have an EPC rating of at least Band E. It’s illegal to let a property with an F or G rating unless you’ve registered a valid exemption on the government’s PRS Exemptions Register.
Key current rules include:
-
A valid EPC must be available before marketing the property
-
EPCs are valid for 10 years
-
Non-compliance can lead to fines of up to £5,000 per property
These standards remain in place, but the government’s upcoming 2026 changes will alter how EPCs are assessed and how compliance is judged.
EPC Changes Coming in 2026
The EPC system is undergoing reform in 2026 to make ratings more accurate and reflective of real-world energy use. Rather than just measuring estimated fuel consumption, the new EPC will also factor in:
-
Carbon emissions and energy source mix
-
Smart readiness and home automation efficiency
-
Insulation and building fabric performance
Additionally, the government has proposed to raise the minimum EPC requirement for rental properties to Band C, expected to apply to:
-
New tenancies by 2028
-
All existing tenancies by 2030
Whilst timelines may shift, it’s clear that landlords will face increasing pressure to improve their properties’ energy performance well before the end of the decade.
What Landlords Should Do Now to Prepare
Rather than waiting until 2026, landlords can start planning upgrades today. Some of the most effective (and affordable) improvements include:
-
Loft and wall insulation
-
Efficient heating systems
-
LED lighting and smart controls
-
Double glazing or draught-proofing
It’s also wise to get an EPC pre-assessment; many professional letting agencies or energy assessors can estimate your current rating and recommend changes needed to hit Band C or higher.
Financial and Letting Impacts of EPC Changes
A better EPC rating can directly impact a landlord’s bottom line. Properties with higher energy efficiency often:
-
Attract better tenants who stay longer and pay premium rents
-
Reduce void periods thanks to improved comfort and lower energy costs
-
Increase resale value for buy-to-let investors
There are also financial aids available, such as:
-
Green Homes funding
-
Tax-deductible improvements tied to energy efficiency
-
Low-interest retrofit loans for landlords in some councils
Ignoring EPC upgrades could make certain homes unlettable in a few years, especially older buildings. Planning means avoiding the rush and inflated contractor costs that will likely hit when the 2026 rules take effect.
FAQs About EPC Rental Property 2026
1. Will EPC rules apply to short-term rentals or holiday lets?
Yes, if your property is let for more than four months in a year, EPC regulations generally apply. However, specific short-term or listed properties may qualify for exemptions.
2. Can I sell my rental property if it doesn’t meet the new EPC rules?
You can still sell, but buyers will factor upgrade costs into their offer. Improving your EPC before selling can raise property value and attract investor interest.
3. Are listed buildings exempt from EPC requirements in 2026?
Yes, but only if compliance would unacceptably alter the building’s character. It’s important to confirm exemptions with your local authority before assuming your property qualifies.
