How Could an EPB Reform Impact Landlords and Tenants?

Reforms to the Energy Performance of Buildings regime Consultation

On 4 December 2024, the UK government launched an extensive consultation on the Energy Performance of Buildings (EPB) framework. This initiative is designed to modernise energy certification, refine performance metrics, and ensure that Energy Performance Certificates (EPCs) – and their related displays – remain relevant as the UK works toward net‑zero emissions in 2050.

Since their introduction in 2012, EPCs have been essential for measuring building efficiency. The current consultation proposes not only updated metrics and certification protocols, but also enhanced data management, improved quality control, and revised enforcement measures – including changes to air conditioning inspection reports. These reforms are particularly significant for landlords and tenants, as they could influence lease agreements, property upgrade decisions, and operating costs.

The consultation, which spans England and Wales (with devolved responsibilities in Scotland and Northern Ireland), is a collaborative effort led by the Ministry of Housing, Communities and Local Government alongside the Department for Energy Security and Net Zero. Over a 12‑week period from 4 December 2024 to 26 February 2025, stakeholders are invited to provide feedback on proposals that include:

1. Clarifying and consolidating current regulations to align with modern technologies and environmental demands – Modernising rules to align with new technologies and environmental demands could require tenants to adapt their spaces to meet updated sustainability standards, potentially prompting operational changes or investments in energy efficiency.
2. Updating EPC metrics to reflect actual energy performance and consumption – Adjusting how energy performance is measured may result in ratings that more accurately reflect actual consumption, affecting leasing decisions, rental costs, and upgrade obligations for properties that are less energy-efficient.
3. Refining the requirements for both EPCs and Display Energy Certificates (DECs) – New standards might require enhanced data-sharing and energy efficiency measures, influencing both landlord compliance and tenant expectations.
4. Improving data management protocols and enforcing higher quality standards – More stringent reporting could impose additional administrative duties on tenants, ensuring that energy usage data is both precise and current.
5. Revising air conditioning inspection reports (ACIRs) to enhance accuracy – Enhanced accuracy in these reports could lead to higher maintenance standards, potentially increasing compliance costs or necessitating upgrades in air conditioning systems.

1. Overview of the Consultation

This consultation focuses on a comprehensive reform of the EPB regime. Key areas under review include:

• Clarifying and consolidating regulations to keep pace with technological and environmental developments.
• Introducing updated performance metrics that better capture real-world energy consumption and carbon emissions.
• Refining the certification process for both domestic and non‑domestic properties.
• Improving data management protocols to ensure EPC information remains accurate and accessible.

These efforts align with the UK’s commitment to net‑zero emissions and addressing fuel poverty while enhancing property standards.

2. What This Means for Landlords and Tenants

For landlords, the proposed reforms may signal increased requirements for property upgrades, more frequent assessments, and stricter compliance measures. For tenants, the changes could offer greater transparency about energy efficiency and potentially lower running costs through improved building performance. Together, these impacts aim to create a more sustainable and economically attractive property market.

3. Anticipated Changes to EPC Requirements

The consultation proposes evolving from a single-rating system to a multi‑metric approach that may include:

• Energy Cost: Updated calculations reflecting modern fuel prices and tariffs.
• Fabric Performance: Detailed assessments of insulation and thermal efficiency.
• Heating System Efficiency: Rankings based on the environmental impact and performance of heating technologies.
• Smart Readiness: Evaluations of a building’s ability to integrate with smart energy systems.
• Energy Use: Metrics focusing on actual consumption patterns rather than estimated costs.

These enhancements could lead to higher minimum standards, such as a requirement for an EPC rating of B for non‑domestic properties, influencing both lease terms and property valuations.

4. Updates to Certification & Data Management

Additional proposals include:

• Reducing the validity period of EPCs and Display Energy Certificates (DECs) to ensure they reflect current building performance.
• Mandating that properties have a valid EPC at the time of sale or rental marketing.
• Streamlining data management by retiring outdated certificates and improving public access to energy performance data.

These measures are expected to enhance compliance and make energy data a more powerful tool for both enforcement and strategic property management.

5. Impact on Leasing and Property Upgrades

With stricter EPC requirements on the horizon, landlords may need to invest in property upgrades sooner. Improved energy efficiency can:

• Enhance property marketability by lowering operating costs.
• Attract higher quality tenants who value sustainability and cost efficiency.
• Potentially secure longer lease durations and higher rental yields.

For tenants, more accurate energy performance data can lead to informed decisions that reduce utility bills and create more comfortable living or working environments.

6. Compliance, Enforcement & Future Penalties

To ensure that the updated EPC requirements are met, the consultation includes proposals for:

• Stricter penalties for non‑compliance to serve as a deterrent.
• Enhanced training and accreditation for energy assessors to improve EPC accuracy.
• Improved coordination among enforcement bodies to better monitor compliance.

These steps are intended to build trust in the energy certification system and ensure reliable property performance data.

7. Opportunities for Property Modernisation

The reform of the EPB regime presents new opportunities for landlords to modernise their properties. Upgraded insulation, advanced HVAC systems, and the integration of smart energy solutions could not only improve building performance but also create a more resilient and sustainable property portfolio.
