Future Changes to EPCs: What Homeowners and Landlords Need to Know

2 Jul

Energy Performance Certificates (EPCs) have been a key part of the UK property market for many years, helping homeowners, landlords, buyers, and tenants understand the energy performance of a property.

However, significant changes to the EPC system are planned over the coming years. The Government has already introduced RdSAP 10 for existing dwellings and is consulting on wider reforms designed to make EPCs more accurate, informative, and relevant to modern energy-efficient homes.

If you own, buy, sell, or let property, understanding the direction of travel can help you prepare for future changes.

Why Are EPCs Changing?

The current EPC system uses a single headline rating from A to G, based largely on the estimated cost of energy required to heat and power a property.

The Government believes future EPCs should provide a broader picture of building performance, helping property owners make better-informed decisions about energy efficiency improvements, carbon reduction, and running costs.

Moving Beyond a Single EPC Rating

One of the biggest proposed changes is the move away from relying solely on a single A-to-G rating.

Future domestic EPCs are expected to include multiple headline metrics, giving a more detailed view of a property's performance. Proposed measures include:

Energy costs
Fabric performance (insulation and heat retention)
Heating system performance
Smart readiness and energy flexibility

Additional information relating to energy demand and carbon emissions may also be included.

This means future EPCs may provide a more complete picture than the current single-score approach.

Greater Recognition of Smart and Low-Carbon Technologies

Future EPC methodologies are expected to better reflect the benefits of modern technologies, including:

Heat pumps
Solar photovoltaic (PV) systems
Battery storage
Smart heating controls
Smart home energy management systems

This aligns with the Government's wider objectives around decarbonisation, energy security, and achieving net-zero carbon emissions.

More Emphasis on Building Fabric

The proposed reforms place increased importance on the physical performance of the building itself.

Features such as:

Loft insulation
Wall insulation
Floor insulation
Airtightness
High-performance glazing

may become more prominent within future EPC assessments.

This reflects a growing focus on reducing heat loss before considering heating technologies or renewable energy systems.

Better Data and Evidence Requirements

Recent changes under RdSAP 10 already require assessors to gather more detailed information and supporting evidence in many situations.

Future reforms are expected to continue this trend, making it increasingly important for property owners to retain documentation relating to:

Insulation upgrades
Heating system replacements
Solar PV installations
Battery storage systems
Renewable energy technologies

Providing suitable evidence can help ensure improvements are properly reflected during an EPC assessment.

What Does This Mean for Landlords?

Landlords should pay particular attention to proposed changes to the Minimum Energy Efficiency Standards (MEES).

The Government has confirmed its intention to require privately rented homes to achieve a standard broadly equivalent to today's EPC Band C by 2030, although the final framework will be linked to the new EPC methodology.

Property owners with lower-rated rental properties may therefore wish to consider energy efficiency improvements sooner rather than later.

When Will the Changes Happen?

The reform process is already underway.

Key milestones include:

June 2025: RdSAP 10 introduced for existing dwellings.
2026–2027: Further EPC reforms and new metrics under consultation.
Second half of 2027: Current Government target for the introduction of reformed domestic EPCs based on the Home Energy Model (HEM).
2030: Proposed higher minimum energy efficiency requirements for privately rented homes.

As with any Government consultation, proposals may change before final implementation.

Frequently Asked Questions

Are EPCs being abolished?

No. EPCs will continue to be required for many property transactions, including sales and lettings. The reforms are intended to improve the information provided rather than remove EPCs altogether.

Will my current EPC still be valid?

Yes. Current EPCs remain valid for their normal validity period unless a new EPC is required for another reason. The Government has confirmed that the existing 10-year validity period will remain in place.

Will smart technology affect future EPCs?

Future EPCs are expected to place greater emphasis on smart readiness and technologies that help households manage energy use more efficiently.

Should I wait for the new EPC system before improving my property?

Not necessarily. Many measures that improve energy efficiency today—such as insulation, efficient heating systems, and renewable technologies—are likely to remain beneficial under future EPC methodologies.
