EPC Legal Requirements for Landlords & Property Owners (UK Guide 2026)
The Energy Performance Certificate (EPC) is a legal requirement for landlords and property owners across the UK in 2026. If a property is being rented, sold, or leased, a valid EPC must be in place before it is marketed. These requirements apply to both domestic and commercial properties and are obligatory for local authorities.
Understanding EPC legal requirements UK landlords must follow helps avoid penalties, delays, and compliance issues. This guide explains the current rules, minimum standards, and what property owners need to be aware of in 2026.
What an EPC Is and When It Is Required
An EPC measures how energy efficient a building is and assigns it a rating from A (most efficient) to G (least efficient). It also includes recommendations for improving performance. Once issued, an EPC is valid for ten years.
Under the EPC certificate law UK, an EPC is legally required when a property is sold, rented, or leased. This is implemented in houses, flats, shops, offices, warehouses, and most mixed-use buildings. An expired EPC cannot be used for marketing, letting, or legal compliance. EPCs must only be carried out by accredited assessors and lodged on the official UK EPC Register. Certificates produced outside this system are not legally valid.
EPC Requirements for Landlords in England and Wales
For residential landlords, EPC requirements for landlords are clearly defined. A privately rented property must have a minimum EPC rating of E before it can be legally let.
The minimum EPC rating rental property rules apply to new tenancies, renewals, and most existing tenancies. Properties rated F or G cannot usually be rented unless a valid exemption has been registered. Advertising or letting a non-compliant property can result in enforcement action.
An effective EPC must be available before marketing begins, and a free copy must be provided to the tenant before the tenancy agreement is signed. These requirements form the basis of EPC compliance for landlords and are regularly checked by local authorities.
Requirements of EPC Compliance for Landlords for 2026: What Property Owners Should Know
EPC compliance involves more than having a certificate on file. The EPC must be current, accurate, and reflect the property as it is being used. If a building has been altered or upgraded, a new EPC may be required. The core EPC rules remain unchanged for the year 2026. EPCs are valid for ten years, a minimum rating of E is required for most rental properties, and EPCs must be in place before marketing.
The government has confirmed plans to update how EPCs are calculated later in 2026, with greater emphasis expected on building fabric, insulation quality, and heating system efficiency rather than energy costs alone. At the same time, proposals under the Warm Homes Plan signal a longer-term move towards a minimum Band C requirement, with new tenancies expected to be affected first from 2028 and existing tenancies by 2030.
These changes are not yet part of the EPC certificate law in the UK, but they are relevant for landlords planning upgrades and long-term compliance, as future EPC assessments may differ from those issued under the current framework.
Commercial EPC Legal Requirements
Commercial EPC rules apply to most non-domestic properties when they are sold or leased. This includes offices, retail units, warehouses, and industrial buildings.
In most cases, a commercial property must meet a minimum EPC rating of E to be valid, unless a registered exemption applies. EPC compliance for landlords in the commercial sector is imposed in the same way as residential properties, with penalties based on the severity of the breach.
Commercial EPCs must reflect the actual use of the building and are assessed differently from domestic properties, making it important to use assessors experienced in commercial EPCs.
EPC Exemptions and Penalties
Some properties may be eligible for EPC exemptions, but such reliefs are limited and must be formally registered. Listed buildings may be exempt only where energy efficiency improvements would unacceptably alter their character. Other exemptions may apply where improvements are not cost-effective.
Failure to comply with EPC legal requirements can lead to financial penalties, restrictions on renting or marketing a property, and execution by local authorities or trading standards. Penalties vary depending on property type and breach severity.
Conclusion
EPC compliance is a legal requirement that affects every stage of selling or renting a property. With strict rules around minimum ratings, ten-year validity, and accredited assessments, property owners must ensure their EPCs are accurate, current, and legally valid.
Many compliance issues arise from expired certificates, incorrect assessments, or EPCs that were not carried out by accredited assessors. These problems can delay transactions and lead to avoidable penalties.
