Non-Domestic MEES Update: Why EPC B Compliance Matters for Commercial Property Owners

The UK’s commercial property sector is waiting for an important policy update that could shape the future of energy efficiency in business premises. The Government’s response to the consultation on Minimum Energy Efficiency Standards (MEES) for non-domestic buildings was expected earlier this year, but is now anticipated in Autumn 2025. This delay is creating uncertainty for landlords, commercial agents and energy assessors who need clarity to plan for compliance.

Under the proposed changes, all privately rented non-domestic properties in England and Wales would need to meet a minimum Energy Performance Certificate (EPC) rating of B by 2030. This is a significant step up from the current EPC E requirement and would have a major impact on the way offices, retail units, warehouses and other commercial spaces are maintained and upgraded.

Why non-domestic MEES matters

Since April 2023, landlords have been required to achieve at least an EPC E before letting a commercial property. Raising the target to EPC B is part of the UK’s commitment to net zero and would bring substantial benefits. Improved energy efficiency can reduce running costs, make properties more attractive to tenants and contribute to lower carbon emissions.

“Non-domestic MEES is one of the most important regulatory tools we have to improve the energy efficiency of commercial buildings,” says Catherine Storer, NDEA at Essential Green Skills. “Without timely guidance, the sector risks falling behind, missing emissions targets and losing the momentum created by recent domestic MEES updates.”

The challenge of uncertainty

The delay in confirming the outcome of the MEES consultation is creating practical challenges. Landlords are hesitant to invest in upgrades without knowing the final requirements and deadlines. Energy assessors are also unable to plan their workload effectively without a clear compliance timetable.

Clear policy guidance would:

• Give landlords confidence to invest in commercial EPC improvements
• Enable assessors to prepare for EPC B compliance work in advance
• Align the non-domestic sector with domestic MEES reforms already underway

“Right now, assessors, landlords and retrofit specialists are having to prepare for multiple scenarios,” adds Catherine. “A confirmed compliance trajectory would lead to smarter investment, better planning and faster delivery of energy savings.”

Aligning with domestic MEES

The domestic MEES framework is already evolving, with new standards being introduced for private and social housing. Aligning non-domestic MEES with these reforms would create a consistent approach and help accelerate progress toward national net zero targets.

“Energy efficiency is not a domestic issue or a commercial issue, it is a national priority,” Catherine says. “The sooner the Government provides clarity, the sooner we can focus on delivering improvements that reduce bills, cut carbon emissions and futureproof our building stock.”

Preparing for EPC B compliance

The uplift to EPC B is achievable if building owners act early. Conducting a commercial EPC assessment now can identify the most cost-effective upgrades and help spread investment over time. When the Government confirms the MEES framework, those who have already taken steps towards compliance will be in the strongest position.

For landlords, the message is clear: start planning now, even before the final policy is announced. Commercial EPC improvements are an investment in the value, efficiency and sustainability of your property.
