EPC Requirements for UK Commercial Buildings

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.

New free guide: Building Regs 2027, what it means for your EPC.

Many landlords are planning refurbishments now to reach EPC B before the 2031 MEES deadline. But the Building Regulations update coming in 2027 is expected to bring a new EPC calculation with it, and that could change the result.

The same building, with the same works, could earn a different rating.

Our new guide explains what's changing and what it means for your strategy. Inside:

• What the Future Buildings Standard changes, and when
• How the EPC calculation works, and which parts are expected to move
• Gas versus electricity: how the carbon factors are expected to shift
• What we learned when we put our clients' questions to CIBSE's technical team
• How the route to B differs for all-electric, gas-heated and mixed buildings
• A worked example: one gas-heated office, two routes to B
• Six steps for planning a refurbishment now

Why it matters: in our worked example, a gas-led refurbishment just reaches B today but could slip back to C under the expected new factors. The electric route gains headroom. The lesson is to aim below the B boundary, not at it, and to test your plans under both methods.

The final details depend on the new NCM modelling guide, which is still to be published. We'll update clients as soon as it is.

Download the guide for free and share it with anyone planning works on a commercial building.

New guide: EPC B by 2031. Is your portfolio ready?

In June 2026, the government confirmed that privately rented commercial buildings over 1,000 m² in England and Wales must reach EPC B from 2031, where cost-effective.

The interim 2027 step has gone. That gives landlords time to plan one well-timed upgrade instead of two rushed ones.

Our free 8-page guide for landlords, asset managers and investors covers:

• MEES in brief
• What changed in June 2026
• Whether the rule applies to your buildings
• Where ratings are lost, and why to fix the data first
• A five-year roadmap to 2031
• Exemptions, plus eight questions for your next portfolio review

Want to know where your buildings stand? We offer a free 2031 exposure check, from a single asset to a whole portfolio.

We’re delighted to share that Silbury House in Milton Keynes has achieved a 5 Star NABERS UK Energy for Offices Whole Building rating, with @Sam Maddock of @Sustainable Urban Solutions acting as the NABERS UK Assessor.

According to the @CIBSE Certification online register, it is currently the only building in the UK holding a 5 Star NABERS UK Whole Building rating, and the third-highest-rated Whole Building certified in the country!

NABERS UK rates offices on their measured energy use in operation, so the rating reflects how the building actually performs day to day. A Whole Building rating covers all the energy used in the building for a year. That includes the landlord’s central services, such as heating, cooling, ventilation, lifts and common area lighting, and the tenants’ own use, such as office lighting, computers and other equipment. A high rating therefore depends on good design, good management and occupiers who use energy sensibly.

The building dates from 1998 and was refurbished rather than redeveloped, avoiding the embodied carbon of demolition and rebuilding. The refurbishment included:

-116 rooftop solar PV panels (41 kWp), generating up to 20% of the building’s energy on site
-Hybrid VRF heating and cooling with heat recovery, moving heat between areas rather than wasting it
-MVHR, providing fresh air while recovering warmth from the air going out
-LED lighting with smart controls that dim or switch off when spaces are empty
-Smart power sockets that help occupiers cut out standby waste

Congratulations to @RO Real Estate and to the team who manage and operate Silbury House. This result reflects both the quality of the refurbishment and the care taken in running the building.

Commercial properties with an EPC rating below B should already be on the radar for landlords, asset managers, investors, and property owners.

With proposed legislation expected to require many commercial properties to achieve a minimum EPC B by 2031, there is significant value in understanding current building performance and identifying the most cost-effective route to compliance.

An updated EPC assessment offers valuable insight into a building's energy performance and can form the basis of a practical improvement strategy, helping to prioritise upgrades, manage capital expenditure, and align works with refurbishment programmes or lease events.

Key benefits include:
✅ A clear pathway towards EPC B
✅ Better-informed investment decisions
✅ Improved asset value and marketability
✅ Reduced energy consumption and operating costs
✅ Greater confidence in future regulatory readiness

Starting the process early allows more flexibility to phase improvements over time, helping to minimise disruption and optimise investment.

For commercial properties currently rated below EPC B, or where the current EPC may no longer reflect the building's performance, an updated assessment is a sensible first step towards developing a clear roadmap to 2031.

The Government has published its interim response on strengthening Minimum Energy Efficiency Standards (MEES) for non-domestic rented buildings in England and Wales, providing some long-awaited clarity for the commercial property sector. Key proposals include:

✅ From 2031, privately rented buildings over 1,000m² will be required to achieve an EPC B rating, where cost-effective.

✅ Buildings below 1,000m² will remain subject to the current EPC E minimum standard.

✅ The previously proposed EPC C milestone in 2027 has been removed, giving landlords and occupiers additional time to plan improvements.

✅ Existing exemptions and the 7-year payback test will remain in place to ensure upgrades are practical and economically viable.

At @Sustainable Urban Solutions, we help clients through detailed baseline EPC modelling, decarbonisation studies, and energy efficiency assessments. Our services provide a clear roadmap to achieving compliance and improving asset performance. By testing improvement scenarios and aligning recommendations with planned maintenance programmes and CAPEX investment cycles, we help clients target the measures that deliver the greatest return on investment while avoiding unnecessary expenditure.

With 2031 approaching, now is the ideal time to understand how your portfolio is likely to perform and develop a practical, phased strategy for achieving EPC B in the most cost-effective way.

We’re kicking off a new project at the YY Building in Canary Wharf, developing a detailed design-stage energy model to test and refine predicted energy use and carbon emissions associated with a tenant fit-out, ensuring alignment with wider landlord NABERS UK targets.

In practice, this type of modelling helps bridge the gap between design decisions and operational performance, supporting more informed choices during the design and fit-out stages.

We're pleased to have delivered a predicted Level 5 EPC assessment (forecast A Rating) for a 3,500m² office building in Central Nottingham as part of a major refurbishment and decarbonisation project.

The refurbishment includes:

✅ Replacing the existing 4-pipe fan coil system served by a gas-fired boiler and air-cooled chiller with a high-efficiency VRF system.

✅ Replacing the existing gas-fired domestic hot water plant with an air-to-water heat pump solution.

✅ Installation of a roof-mounted solar PV system.

These upgrades will significantly improve the building's energy performance, reduce operational carbon emissions, and support the transition away from fossil fuel-based systems.

A key outcome from the EPC modelling was the ability to optimise the renewable energy strategy and PV specification. By refining the design through detailed analysis, we demonstrated that the project could still achieve the forecast EPC A Rating while reducing the required PV capacity.

This insight delivered a substantial capital expenditure saving for the client, avoiding unnecessary oversizing of renewable technology while still achieving the required EPC outcome.

It highlights the value of undertaking predicted EPC analysis early in the process and informing decisions that can materially improve project viability and reduce capital cost.

🎉 Thank you to everyone who participated in our Net Zero Awareness Award this year at the SAED MSc Oxford Brookes University end-of-year exhibition.

What an inspiring evening celebrating the outstanding projects designed and delivered by this year’s students. The quality of work on display was exceptional, with students demonstrating not only creativity and technical ability, but also a genuine understanding of the challenges and opportunities facing the industry today. It is a privilege to sponsor an award that not only recognises excellence, but also encourages the next generation to drive meaningful change within the industry and give back to the course and community that support them.

This year’s award focused on Net Zero awareness within the built environment, challenging students to develop projects that not only strive to achieve net zero in practice, but also communicate those ideas clearly, practically, and with passion.

With Net Zero now a key requirement of the London Plan, low-energy and net-zero buildings will increasingly come under scrutiny for how they perform in the years ahead. Helping the public and building users better understand what net zero really means will be vital in supporting wider sustainability goals and driving change from the ground up, creating greater demand for more sustainable buildings.

Congratulations to all of the students shortlisted for the award, and to this year’s winners.

🥇 1st Place and £500 Award - Maximilian Cook

🥈 2nd Place - Ar. Rochelle Dsouza & Ellie Pearce

🥉 3rd Place - Paola Herrera

The show remains open at the School of Architecture, @Oxford Brookes University until the 20th of June.

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.
