The UK government has published a partial response to its consultation on Reforms to the Energy Performance of Buildings regime, outlining significant updates to how Energy Performance Certificates will operate from 2026 onwards. While much of the reform focuses on domestic EPCs, there are important implications for commercial landlords, particularly around when EPCs are required and how the regime will apply across different rental sectors.

This article summarises what has been confirmed so far, using only information published in the official consultation documents and partial government response.

Why the EPC Regime Is Being Reformed

The consultation, launched on 4 December 2024 and closed on 26 February 2025, sought views on:

  • What reformed EPCs should measure
  • When EPCs should be required

The reforms are part of the government’s broader objectives to:

  • Support progress toward net-zero emissions by 2050
  • Alleviate fuel poverty
  • Improve building standards
  • Enhance transparency for consumers and businesses

The Ministry of Housing, Communities and Local Government, supported by the Department for Energy Security and Net Zero, is leading these changes in England and Wales.

Headline Change for Commercial EPCs, Carbon Rating Retained

One of the most important clarifications for commercial landlords is that non-domestic EPCs will retain the single carbon-based Environmental Impact Rating as the headline metric.

During consultation, views were sought on whether additional metrics should be added. However, the government has confirmed that:

  • The carbon-based Environmental Impact Rating will remain the primary headline metric for non-domestic EPCs.

This decision is intended to:

  • Support businesses in the net zero transition
  • Enable emissions reporting
  • Facilitate compliance with non-domestic Minimum Energy Efficiency Standards regulations

While some respondents highlighted that the carbon intensity of electricity generation is outside the control of building owners, the government has decided to maintain this approach.

For commercial landlords, this means that the overall structure of non-domestic EPC scoring will not fundamentally change in 2026.

EPC Validity Period, No Reduction

The consultation explored reducing EPC validity from the current ten-year period to a shorter timeframe.

Many respondents, particularly landlords, expressed concern about:

  • Increased cost
  • Administrative burden
  • Workforce capacity

The government has confirmed that:

  • The ten-year validity period will be maintained for reformed EPCs.
  • Existing EPCs will also retain their ten-year validity.

For commercial landlords, this provides continuity and avoids the need for more frequent reassessments solely due to regulatory reform.

EPC Required at the Point of Marketing

A more significant operational change for commercial landlords concerns when an EPC must be in place.

Currently, regulations allow up to 28 days after marketing begins for an EPC to be obtained.

The government intends to update regulations so that:

  • A valid EPC must be in place before a property is marketed for sale or rent.

The majority of consultation respondents supported this proposal, recognising that prospective buyers and tenants should have access to energy performance information at the decision-making stage.

For commercial landlords and managing agents, this means:

  • EPCs must be commissioned earlier in the transaction process.
  • Marketing cannot legally begin without a valid certificate in place.

This change is designed to improve clarity and strengthen compliance and enforcement.

Houses in Multiple Occupation, Whole Property EPC Required

The government intends to clarify the scope of the regime so that:

  • A valid EPC is required for the whole HMO when a single room is let.

While this primarily affects residential HMOs, it signals a broader government approach of ensuring consistent information across rental sectors.

Short-Term Rental Properties Brought Into Scope

The consultation addressed short-term and holiday lets, where regulatory requirements have previously been less explicit.

The government intends to update regulations so that:

  • Short-term rental properties must have a valid EPC when let.
  • This applies irrespective of who pays the energy bills.

Although this change is primarily residential in impact, it reflects a wider move toward expanding EPC coverage across building types and tenures.

Heritage Buildings, Exemptions to Be Removed

One of the more controversial proposals concerned removing the exemption for heritage properties.

The government has stated its intention to:

  • Remove the exemption allowing landlords of heritage buildings to avoid obtaining an EPC.

While consultation responses raised concerns about suitability of retrofit recommendations and cost implications, the government’s position is that removing the exemption provides:

  • Greater clarity
  • Better information for owners and consumers
  • Improved consistency across the private rented sector

Importantly, the government noted that where MEES applies, exemptions remain available to ensure owners are not mandated to install unsuitable measures.

For commercial landlords with listed or heritage buildings, this means EPC requirements may apply more consistently in future.

Interaction With MEES Regulations

The government confirmed it is working to ensure that:

  • Revised Energy Performance of Buildings regulations
  • Private Rented Sector MEES regulations

interact effectively without placing undue burdens on landlords.

The final position on requiring a new EPC when one expires during a tenancy is still being refined. Further detail will be published in 2026.

For commercial landlords, it remains critical to monitor how EPC reform aligns with evolving MEES requirements.

Transition to New-Style EPCs

New-style domestic EPCs are expected from October 2026, subject to parliamentary approval.

For non-domestic buildings:

  • The headline carbon-based metric will remain.
  • The ten-year validity period will continue.

The government has acknowledged that implementation timelines are ambitious and has committed to engaging with industry to support transition.

Further responses covering:

  • Display Energy Certificates
  • EPC and DEC data
  • Managing EPC quality
  • Air Conditioning Inspection Reports

are expected in 2026.

What Commercial Landlords Should Do Now

Based on the confirmed reforms:

  • Ensure EPCs are commissioned before marketing begins.
    This will become a clearer regulatory requirement.
  • Maintain compliance with the ten-year validity rule.
    No reduction has been confirmed.
  • Monitor updates on MEES interaction.
    Further clarification is expected in 2026.
  • Review heritage property portfolios.
    Removal of exemptions may require additional EPC coverage.
  • Stay engaged with regulatory updates through 2026.
    Additional responses will finalise transitional arrangements.

Conclusion

The 2026 EPC reforms introduce structural change for domestic EPCs but maintain continuity for non-domestic certificates by retaining the carbon-based Environmental Impact Rating and ten-year validity period. For commercial landlords, the most immediate operational change will be the requirement to hold a valid EPC before marketing a property. Broader scope changes, including inclusion of heritage and short-term properties, reflect the government’s intention to provide a fuller picture of building energy performance across the country. Further detail will be published in 2026 as the government finalises regulations and prepares for implementation. Commercial landlords should continue to monitor official updates and ensure their EPC and MEES strategies remain aligned with evolving regulatory requirements.

How Should Ventilation Be Managed in Winter?

Ventilation systems affect both air quality and heating efficiency.

During winter, excessive ventilation can dramatically increase heating demand. Consider:

  • Reducing ventilation rates in low occupancy periods
  • Ensuring vents are clean and operational
  • Checking heat recovery systems

Air leaks increase heat loss. Check:

  • Door seals
  • Window frames
  • Roller shutter gaps in warehouses
  • Loading bay areas
