EPC Standards for Commercial Properties: 2030 update

Energy rules for commercial buildings are becoming stricter. From 2030, it’s expected that updated EPC requirements will raise the minimum energy efficiency standards (MEES), meaning many commercial properties will need to meet higher performance levels than before.

If you’re a landlord, property manager, investor, or responsible for commercial premises, it’s clear that buildings must become more energy-efficient, reduce carbon emissions, and meet higher minimum energy performance standards. This is part of the government’s wider strategy to support the UK’s commitment to reaching net zero by 2050.

At a glance:

• The current minimum EPC rating for most non-domestic rented buildings is E.
• Proposed changes will require many commercial properties to reach an EPC rating of B by 2030.
• Commercial landlords who fail to comply may face penalties and restrictions on letting.
• Early planning allows you to improve energy efficiency cost-effectively and protect asset value.

If you’re unsure about your building’s current energy performance or what will be required to meet the new standards, it’s important to take action sooner rather than later. Early assessment gives you the flexibility to plan upgrades properly, manage costs effectively, and ensure compliance without unnecessary pressure.

What is a commercial EPC?

A commercial energy performance certificate measures a building’s energy efficiency and carbon footprint by assessing energy consumption, fixed heating systems, air conditioning systems, mechanical ventilation systems, insulation, lighting, and overall thermal efficiency, and assigning an EPC rating from A to G.

For commercial landlords and property owners, the EPC rating directly affects legal compliance, commercial property sales, lease negotiations, commercial lease renewal, operational costs, and the overall marketability of a commercial building.

A valid commercial EPC is a legal requirement when selling, leasing, or constructing commercial property. Beyond compliance, it provides a benchmark of a building’s energy performance and highlights where energy efficiency improvements can reduce energy usage and carbon emissions.

Better commercial EPC ratings not only support sustainable operations and environmental sustainability but also improve a property’s appeal to tenants and prospective buyers, and help future-proof commercial premises against tightening minimum energy efficiency standards.

What’s being updated for commercial EPC standards for 2030?

The proposed 2030 update builds on the existing energy efficiency standards (MEES) framework. The structure of the regulations is not being replaced; instead, the performance threshold is expected to increase.

The key proposals:

An increase in the minimum EPC rating

The current minimum EPC rating for most non-domestic rented buildings is E. The government has consulted on raising this requirement to a B rating by 2030.

If implemented, this would represent a significant increase in the required energy performance of commercial properties across England and Wales.

Potential staged compliance milestones

Alongside the proposed move to raise the minimum rating requirement to B by 2030, earlier consultation documents suggested interim checkpoints before it fully comes into effect. These staged intervals have not yet been finalised, but they indicate a likely phased transition rather than a single deadline.

The overall direction is clear: progressively higher minimum energy performance requirements within the existing regulatory framework.

What will this mean for commercial landlords?

If the minimum rating is raised to B, a greater proportion of commercial buildings will fall below the legal letting threshold.

This would affect:

• New lettings
• Existing tenancy arrangements
• Commercial lease renewal
• Commercial property sales

Buildings currently rated D or E that meet today’s minimum standard may need improvement works to continue being legally let if the new threshold is introduced. For landlords and property managers, this means reviewing properties early, budgeting for potential upgrades, and planning ahead to avoid disruption or compliance issues.

When does the 2030 update come into effect?

The proposed changes are widely associated with a 2030 deadline, with 1st April 2030 frequently referenced. However, the final legislation and timetable have not yet been confirmed.

Previous consultations suggest the transition may be phased rather than introduced all at once. While details remain subject to confirmation, this could potentially involve:

• Meeting a higher interim minimum EPC rating ahead of the final threshold
• Achieving the proposed EPC B rating by 2030

As improvements such as upgrading fixed heating systems, improving thermal efficiency, or installing renewable energy technologies require planning and investment, reviewing your building’s current EPC position now allows for a measured, cost-effective approach, rather than reacting once the final framework is confirmed.

Next steps to prepare your commercial property for 2030

Meeting the proposed minimum energy performance requirements requires a structured approach. Here are some practical steps to take:

Review your existing EPC

Start with your current commercial energy performance certificate. Confirm:

• Is the EPC still valid?
• What is the current EPC rating?
• When does it expire?
• What improvement recommendations are listed?

An outdated or inaccurate EPC may not reflect the building’s true energy performance or recent upgrades.

Book an updated commercial EPC assessment

If your certificate is due to expire, or if improvements have been made, instruct accredited energy assessors to conduct a new assessment.

A professional commercial EPC provides:

• An accurate reflection of the building’s energy consumption
• Clarity on the gap between the current rating and a B rating
• A clear roadmap of energy efficiency improvements
• Confidence that the property meets current commercial EPC requirements

This is particularly important for complex buildings with multiple systems, such as office buildings, retail premises, and industrial sites.

Plan and implement energy efficiency improvements

Improving the building’s energy efficiency may require targeted upgrades across key systems, which an EPC can recommend. This can include improvements to heating and ventilation systems, insulation, and the incorporation of renewable energy sources, such as solar panels.

Where properties are tenanted, improvements should be planned strategically around lease renewals and tenancy transitions. Taking a phased, portfolio-wide approach reduces disruption, supports smoother commercial lease renewals, and allows investment to be managed in a controlled, cost-effective way.

The risks of non-compliance

If a commercial property fails to meet the applicable minimum EPC rating, landlords may be prohibited from legally letting the building. Local authorities can impose financial penalties – currently up to £150,000 per breach, depending on rateable value – and may publish details of non-compliant properties.

Beyond fines, non-compliance can delay commercial lease renewals, disrupt commercial property sales, reduce tenant demand, and negatively affect asset value. In an increasingly sustainability-focused market, poor commercial EPC ratings also present reputational and investment risk.

When is an EPC not required for commercial property?

While most commercial buildings require a valid energy performance certificate, certain exemptions apply under current EPC regulations. Common exemptions include:

• Temporary buildings: Structures intended to be used for less than two years.
• Small detached buildings: Detached buildings with a total floor space of under 50m².
• Non-residential agricultural buildings: Low-energy agricultural buildings that are not used as dwellings.
• Buildings scheduled for demolition: Where relevant planning permission for demolition has been granted, and the building is to be demolished.
• Listed buildings: Where carrying out energy efficiency improvements would unacceptably alter the character or appearance of the building.

It is important to confirm exemption eligibility and ensure any required registrations are completed.

Summary

The proposed 2030 update to EPC standards for commercial properties is expected to raise the minimum energy efficiency standards for non-domestic rented buildings, with a likely move from the current minimum EPC rating of E to a B rating. While the final legislation and timetable are still to be confirmed, the focus is on higher energy performance expectations within the existing MEES framework.

For commercial landlords and property managers, this means reviewing current EPC ratings, identifying potential improvement works, and planning ahead. Taking a structured approach now – through assessment, targeted upgrades and strategic investment – helps reduce compliance risk, protect asset value, and position commercial properties for a more energy-efficient future.
