EPC Requirements for UK Commercial Buildings
EPC Requirements Diagram

EPC Requirements
and Compliance

Energy Performance Certificates (EPCs) are essential for every leased commercial property, providing a clear rating of energy efficiency from A (most efficient) to G (least efficient). Under the current Minimum Energy Efficiency Standards (MEES), landlords cannot let properties with an EPC rating below E, unless a valid exemption applies.

Future requirements are tightening: by 2030, commercial properties are expected to achieve a minimum EPC rating of B, with a possible trajectory towards A by 2035.

These changes are designed to reduce carbon emissions, improve building performance, and align the sector with the UK’s net‑zero commitments. For landlords, this means acting early to upgrade assets is critical. Not only to avoid compliance risks and penalties, but also to protect rental income, strengthen asset value, and remain competitive in a market increasingly driven by sustainability.

MEES Timeline for Commercial Properties

EPC E 2018

Initial Requirements

Unlawful to grant new leases for properties with EPC rating below E.

2018
-2023

Transition Period

Landlords could continue letting existing F and G-rated properties, but were expected to plan upgrades.

EPC E 2023

Full Enforcement

Extended to all leases: properties rated F or G cannot be let unless a valid exemption applies.

2023
-2030

Transition Period

Current minimum remains EPC E, but landlords are advised to prepare for the next threshold.

EPC B 2030

Future Requirement

Proposed tightening: minimum EPC rating raised to B for all commercial lettings.

2030
-2035

Transition Period

Market adjustment period, with government signalling ambition to move towards EPC A.

EPC A 2035

Potential Requirement

Minimum EPC rating could progress to A, aligning with net-zero commitments.

Our team has completed a Level 5 EPC assessment for a prime, multi-let Grade A office building, specifically to evaluate MEES risk and identify targeted EPC improvement opportunities.

This is a substantial asset, approximately 300,000 sq ft of office space, with large flexible floorplates and complex HVAC systems.

Our scope involved building a large-scale dynamic simulation model in #IESVE and scenario testing multiple upgrade pathways. For assets of this size, the model becomes a project in itself. The Level 5 (DSM-based) approach allowed us to:

✔️ Stress-test the asset against tightening MEES thresholds
✔️ Quantify EPC uplift from improvement measures
✔️ Identify phased, cost-effective upgrade strategies
✔️ Avoid unnecessary or misdirected capital spend

📍This week, our team was in Leeds undertaking detailed site surveys across two commercial buildings as part of updated Level 5 Dynamic Simulation Model (DSM) EPCs.

Both assets form part of a major mixed-use business district that has transformed a former industrial site into a vibrant commercial and public destination.

For Level 5 DSM EPCs, on-site verification is critical. Our surveys focused on:
• Confirming HVAC systems and control strategies
• Validating thermal zoning
• Reviewing lighting installations and existing building fabric
• Collecting comprehensive audit-ready evidence

This level of detail ensures the most accurate, optimised EPC results, delivering real benefits for building owners and managers:
✔ Clear understanding of energy performance
✔ Compliance with current regulations
✔ Insight for future refurbishment and sustainability planning
✔ Enhanced asset value and marketability

If you’re reviewing your portfolio’s EPC strategy or require Level 5 DSM support, our team would be pleased to discuss.

We’re pleased to share that our team is now accredited as NABERS UK Assessors.

For those less familiar, NABERS UK is a rating system that measures how a building actually performs once it’s in use, based on real energy data. It focuses on operational performance rather than design predictions, giving owners, occupiers and investors a clear, comparable view of energy efficiency.

NABERS was established in Australia, where it has had a measurable impact on the office market:

• More than 75% of Australian office buildings are now NABERS rated
• Around half of the rated offices achieve 5 stars or above
• Average energy reductions of 40% and emissions reductions of over 50%
• Consistently linked to higher occupancy levels and rental premiums

With NABERS now established in the UK, we’re looking forward to supporting clients in understanding how their buildings are really performing and identifying practical opportunities to improve efficiency, reduce costs and support net zero ambitions.

Thanks to #CIBSECertification for the accreditation and to everyone working to raise the bar on building performance.

Great to see another building achieve an EPC A rating following a major refurbishment.

@Sustainable Urban Solutions were involved from the early refurbishment design stage back in 2022, helping shape the strategy around energy performance from the outset. The focus was on improving the existing building with upgrades targeted specifically at efficiency and decarbonisation.

Upgrade works included:
• New AHUs with heat recovery
• Daikin VRF systems for efficient heating and cooling
• Electric point-of-use water heaters to reduce losses
• LED lighting with daylight dimming and PIR control throughout

Achieving an EPC A rating means the building is fully compliant with current #MEES requirements and well placed for any future tightening of the regulations. It also showcases reduced energy costs, lower carbon emissions, and helps protect the long-term value of the asset.

A good example of how the right refurbishment strategy can significantly improve performance in existing commercial buildings.

We’ve recently upgraded a G-rated commercial unit to a B-rated EPC simply by ensuring the EPC accurately reflected the current tenant fit-out.

The improvement was driven by:
🔌 All-electric building
♨️ Heat pump systems for space conditioning
💡 Efficient LED lighting throughout
📝 Capturing the tenant’s actual installation and layout

This is a great example of how outdated EPCs can seriously misrepresent a building’s performance. In many cases, reviewing and updating the assessment can unlock major rating improvements and help futureproof assets against MEES and the EPC B by 2030 target.

If your EPC hasn’t been revisited since a tenant fit-out, it’s probably worth another look.

Is your commercial EPC accurately reflecting your asset’s performance?

Many commercial EPCs are outdated or based on default modelling assumptions, rather than verified building data. This can result in ratings that underrepresent the true efficiency of the asset.

Our approach focuses on a detailed technical review of the building, often identifying opportunities to improve EPC ratings without the need for physical upgrades.

For clients, this delivers commercial benefits:

- Improved MEES compliance and reduced regulatory risk
- Enhanced asset marketability for lettings, disposals, and refinancing
- Cost avoidance by eliminating unnecessary capital expenditure
- Greater confidence for investors, occupiers, and lenders

If your EPC is several years old or based on assumptions, a data-led reassessment could unlock immediate value.

Getting the timing right is key to a meaningful NABERS UK Energy for Offices assessment ⚡🏢

If you’re wondering when to undertake your assessment, here’s what delivers the most accurate and valuable results:

✅ 12 months at full occupancy
NABERS UK measures actual operational performance. For the most robust rating, the building should be fully occupied and operating normally for at least 12 continuous months, ensuring the data reflects real-world use.

✅ Energy efficiency measures already embedded
Optimum results are achieved when energy-saving measures such as optimised controls, efficient plant, and improved operational practices are already in place and performing as intended. NABERS rewards actual performance, not design intent.

✅ Detailed sub-metering is essential
Accurate, well-configured sub-metering is critical. It enables clear separation of landlord and tenant energy use and ensures the assessment is credible and compliant.

🔍 The value of an initial assessment
Even if a building isn’t yet at peak performance, an initial NABERS UK assessment can be incredibly valuable. It highlights where energy consumption can be reduced, identifies operational inefficiencies, and provides a clear roadmap to improve performance, helping prepare the building for a stronger result at the next assessment.

💡 In summary:
Undertake a NABERS UK Energy assessment when your building is stable, occupied, efficiently operated, and properly metered. Done at the right time, it becomes a powerful tool to drive improvement, support ESG goals, and enhance asset value.
