Major Changes to EPCs in Scotland: What Businesses Need to Know

Introduction

The Scottish Government is set to introduce significant changes to Energy Performance Certificates (EPCs) from 2026, particularly for non-domestic buildings. These revisions aim to improve clarity, consistency, and usability while aligning Scottish EPCs more closely with those used in England, Wales, and Northern Ireland.

One of the most notable updates is the introduction of a reformed rating system, focusing on direct emissions and energy demand, alongside the continued use of primary energy ratings. Additionally, the validity period of EPCs will be reduced from 10 years to 5 years, ensuring that energy efficiency data remains up to date and relevant.

With these major changes on the horizon, businesses and property owners must understand how the new system will work, what it means for compliance, and how to prepare.

Why Is Scotland Changing EPCs?

One of the primary drivers behind these reforms is the lack of alignment between Scotland’s current non-domestic EPC ratings and those used elsewhere in the UK.

Many stakeholders expressed concerns that the inconsistencies between rating systems made EPCs difficult to compare and interpret. In response, the Scottish Government has redesigned the EPC framework to enhance transparency and bring Scottish non-domestic EPCs in line with the wider UK market, working within the framework of the Building (Scotland) Act 2003 and the Energy Performance of Buildings (Scotland) Regulations 2008.

Additionally, the changes aim to:

• Improve consumer understanding of energy performance.
• Provide clearer insights into a building’s emissions and energy use.
• Support Scotland’s net-zero targets by ensuring more accurate and actionable energy performance data.

What Are the Major Changes to Scottish EPCs?

From 2026, Scotland’s non-domestic EPCs will include a reformed set of metrics designed to give a more comprehensive picture of a building’s energy performance. These major changes represent the most significant update to Scotland’s EPC framework since the regulations were first introduced.

The New EPC Rating System for Non-Domestic Buildings

1. Energy Efficiency Rating (A–G Scale)

• This rating will now match the Asset Rating system used in England, Wales, and Northern Ireland, allowing businesses and property professionals to compare EPCs more easily across the UK.

2. Direct Emissions Rating

• This metric will provide a clear breakdown of a building’s direct carbon emissions, helping businesses understand their environmental impact and work towards decarbonisation goals.

3. Energy Demand Rating

• This rating will indicate regulated energy use, giving a useful comparison point for evaluating a building’s energy efficiency against similar properties.

4. Primary Energy Rating

• The Primary Energy Rating will remain, ensuring that Scottish EPCs can still be compared with European EPC standards.

Introduction of Heating System Ratings

In addition to the new EPC rating system, Scotland’s non-domestic EPCs will now include a specific classification for the main heating system. This follows a similar approach to the domestic EPC reforms, with heating systems categorised as:

• Clean Heating: Low or zero-emission systems (e.g., heat pumps, district heating from renewable sources).
• Renewable Bioenergy: Systems using sustainable biofuels.
• Hybrid Systems: A mix of renewable and fossil fuel-based heating.
• Polluting Heating: Systems reliant on fossil fuels, which will likely be subject to stricter regulatory measures in the future.

This addition ensures that EPCs provide greater clarity on the environmental impact of heating systems and support the transition to cleaner energy solutions.

EPC Validity Period Reduced to 5 Years

Perhaps one of the most impactful changes is the reduction of EPC validity from 10 years to 5 years.

This change aims to:

• Ensure EPCs reflect recent energy efficiency improvements.
• Provide more relevant data for buyers, tenants, and property investors.
• Encourage more frequent assessments, helping businesses stay on top of regulatory changes and identify energy-saving opportunities sooner.

While some energy professionals have called for even shorter EPC validity periods (such as 3 years), the 5-year timeframe is seen as a step in the right direction.

When Do the New EPC Rules Take Effect?

The reformed EPC system will come into effect in 2026. The Scottish Government has indicated that transitional arrangements will be put in place to ensure a smooth changeover from the existing system to the new framework.

Property owners should note that existing EPCs issued before 2026 will remain valid until their expiry date. However, any new EPCs commissioned from 2026 onwards will follow the reformed rating system and include the new heating system classifications.

More detailed implementation guidance is expected from the Scottish Government in advance of the 2026 deadline. For the latest official information, consult the Scottish Government’s energy efficiency policy pages.

Do I Need to Renew My EPC Before 2026?

If your current EPC remains valid through 2026 and beyond (within its 10-year validity period), you are not legally required to renew it early. However, there may be strategic reasons to consider an earlier renewal:

• Properties undergoing significant energy efficiency improvements may benefit from an updated certificate that reflects these enhancements.
• Landlords preparing for transactions or lease renewals may prefer to obtain a current certificate under the existing system before the transition.
• Understanding your property’s performance under the new metrics can help with planning for future compliance requirements.

Once your existing EPC expires after 2026, any renewal will automatically use the new rating system and 5-year validity period.

What Happens If My Building Has Polluting Heating?

Buildings classified with “polluting heating” systems (those reliant on fossil fuels) will need careful consideration. While the new classification does not immediately prohibit these systems, it signals future regulatory direction towards decarbonisation.

Property owners with fossil fuel heating should:

• Plan for potential future restrictions on polluting heating systems in commercial properties.
• Investigate alternative heating technologies, including heat pumps, district heating connections, or hybrid systems.
• Consider the impact on asset value and lettability as tenants increasingly prioritise environmental performance.
• Factor heating system upgrades into longer-term capital expenditure planning.

The heating system classification will likely become increasingly important as Scotland progresses towards its net-zero targets and as environmental, social, and governance (ESG) considerations become more prominent in commercial property decision-making.

How These Changes Affect Businesses

With Scotland’s EPC framework evolving, businesses and landlords must be prepared for the new compliance landscape. These major changes will have implications across the commercial property sector.

For Property Owners and Landlords

• Non-compliance could impact rental and resale values, making it essential to stay updated on EPC regulations.
• Investing in energy efficiency improvements will become more critical, especially with increased focus on direct emissions and heating system classifications.
• Comparability with UK-wide EPCs may impact investment decisions, particularly for businesses operating across different regions.
• The shorter 5-year validity period will require more frequent reassessments and associated costs.

MEES Phase 2 2027 Considerations

Scottish commercial landlords must also be aware of the interaction between these EPC reforms and the Minimum Energy Efficiency Standards (MEES) Phase 2 requirements coming into effect in April 2027 for England and Wales. While MEES applies primarily to England and Wales under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, Scotland has its own energy efficiency requirements for rented properties.

Landlords with portfolios spanning both Scotland and the rest of the UK should:

• Understand how the different rating systems compare when assessing compliance.
• Plan improvement works that address both Scottish EPC requirements and MEES obligations.
• Consider how the reformed Scottish EPC metrics align with broader decarbonisation goals.
• Monitor developments in Scottish commercial property energy efficiency regulations, which may follow similar trajectories to MEES.

Preparing for the 2026 EPC Changes

With the Scottish EPC reforms coming into effect in 2026, businesses and energy professionals should take proactive steps to ensure compliance and take advantage of new opportunities.

Key Actions to Take Now:

1. Review Current EPCs
   • Assess whether existing EPC ratings align with upcoming changes.
   • Identify potential improvements to boost energy performance.
   • Understand when current certificates expire and plan for renewals under the new system.
2. Upgrade Heating Systems
   • With heating now a separate classification, businesses should consider investing in cleaner, low-carbon heating solutions.
   • Evaluate the feasibility of transitioning from polluting heating to clean or hybrid systems.
3. Plan for More Frequent EPC Renewals
   • With the new 5-year validity period, businesses must schedule regular reassessments to remain compliant.
   • Budget for increased assessment costs over time.
4. Seek Expert Guidance
   • Engaging with energy assessors or EPC specialists can help businesses navigate the complex regulatory landscape and identify cost-effective energy efficiency measures.
   • Consider comprehensive energy reports that go beyond basic EPC requirements to inform strategic decarbonisation planning.
