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.

Successful completion of a recent Level 5 EPC assessment for a commercial office project.

Through a detailed approach, we were able to identify improvements that delivered an uplift from a B to an A rating.

For the client, this A-rated EPC enhances asset value, improves marketability, and signals strong energy efficiency performance. It also future-proofs the building against tightening regulatory standards. This is particularly significant in the context of MEES (Minimum Energy Efficiency Standards).

With regulations continuing to evolve, especially for non-domestic properties, achieving an A rating positions the asset well ahead of current requirements and anticipated future thresholds, reducing risk and avoiding potential penalties or letting restrictions.

If you're considering how to improve your building’s EPC rating or prepare for upcoming MEES changes, feel free to get in touch.

We recently carried out a full EPC reassessment on a commercial unit, and the impact of getting the details right was significant:

✅ EPC improved from C to B
✅ Assessment upgraded from Level 3 to Level 5
✅ Corrected heating fuel (previously recorded as gas, actually electric)
✅ Increased recorded floor area by 25% uplift on the original

This is a perfect example of how inaccurate data can hold a property back. By taking the time to reassess properly and apply the correct methodology, we unlocked a higher rating and a more accurate reflection of the building’s performance at no additional cost.

If you’re relying on an older EPC, it may be worth revisiting, especially with tightening regulations and increasing pressure on commercial properties to perform.

Feel free to get in touch if you’d like us to review yours.

We recently completed six Commercial Energy Performance Certificates (EPCs) for newly created retail units at Jura House in Aberfeldy. The project involved the conversion of former residential flats into modern commercial spaces, supporting the ongoing regeneration of the local area and creating opportunities for new businesses.

As part of the process, @Sustainable Urban Solutions analysed and optimised the U-value targets for both existing and new construction elements, and reviewed the HVAC strategy and efficiency targets for the scheme to ensure the development achieved full compliance.

It’s always rewarding to support projects that give existing buildings a second life while contributing to the wider regeneration of an area. Great to see the progress being made across the Aberfeldy estate and to have played a small part in the journey.

A positive step forward for decarbonising the UK built environment.

NABERS UK Energy for Offices ratings, certified by the Chartered Institution of Building Services Engineers (#CIBSE), are now recognised by the UK Net Zero Carbon Buildings Standard (#UKNZCBS) as meeting its operational energy requirements.

This recognition strengthens NABERS UK’s role as a trusted benchmark for measuring real operational energy performance in office buildings. It also simplifies compliance for building owners, enabling NABERS UK ratings to demonstrate alignment with the Standard’s operational energy criteria.

By aligning these frameworks, the industry gains clearer pathways to validate building performance, improve energy efficiency, and accelerate the transition to a net-zero built environment.

If you're looking to understand how your building performs or how to achieve a NABERS UK rating, feel free to get in touch. We’re helping organisations measure, improve, and demonstrate real operational energy performance.

Another A-rated Level 5 #EPC assessment was completed this week on a prime office building in Maidenhead. A great example of how the right combination of refurbishment and efficient building services can significantly improve energy performance.

The property comprises approximately 12,250 sq ft arranged over three floors and benefits from a fully electric setup, supported by VRF air conditioning and LED lighting throughout. Renewable electricity is also generated on-site via solar PV.

Following our detailed modelling process, the EPC has been uplifted from a B rating to an A rating. A fantastic result and a clear demonstration of how targeted upgrades and efficient systems can move a building into top-tier EPC bands.

With MEES regulations tightening and occupiers increasingly prioritising sustainable, energy-efficient space, improvements like this are becoming more important than ever. Always rewarding to see a building make the jump from good to outstanding energy performance.

We’ve completed two Level 5 #EPC assessments, covering office buildings with approximately 145,000 sq ft and 97,000 sq ft respectively. Both buildings achieved a B-rated EPC, demonstrating strong energy performance.

Both buildings feature modern office HVAC strategies, including AHUs with heat recovery, fancoils, LED lighting, smart controls, solar PV, and efficient building fabric.

This means both buildings comfortably meet the Minimum Energy Efficiency Standards for commercial properties (known as MEES). Achieving a B-rating not only meets the current standards but also future-proofs the assets for the proposed 2030 targets.

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
