MEES Myths: Separating Compliance from Confusion

Vital Myth Busters, Part 3

Understanding what MEES really means for commercial property owners

Minimum Energy Efficiency Standards, known as MEES, remain a source of confusion across the commercial property sector. Many landlords, investors, asset managers and managing agents are unsure which properties the rules cover, what the current requirements are and what they should be doing to prepare for future changes.

The starting point is simple: an EPC assesses. MEES regulates.

Understanding the difference is the first step towards making informed property decisions.

Myth 1: “MEES and EPCs are the same thing.”

An Energy Performance Certificate, or EPC, assesses a building’s energy performance using a standardised methodology and gives it an energy efficiency rating from A to G.

Minimum Energy Efficiency Standards are the legal requirements that determine the minimum EPC rating certain privately rented properties must meet, unless a valid exemption applies.

In England and Wales, the current minimum standard for covered non-domestic rented property is EPC E.

Think of it simply: the EPC provides the rating. MEES sets the legal minimum standard. We covered the difference in more detail in Part 2 of this series.

Myth 2: “If my building is compliant today, I don’t need to think about MEES.”

Meeting today’s minimum requirements does not necessarily mean a building is prepared for future changes.

In June 2026, the Government confirmed its intention to introduce a higher minimum standard for privately rented non-domestic buildings in England and Wales. Under the intended approach, buildings over 1,000 square metres would need to reach EPC B from 2031, where cost effective, subject to secondary legislation.

The previously proposed EPC C milestone for 2027 is not being taken forward.

EPC B is not yet the legal minimum. For now, the minimum MEES standard for covered non-domestic rented property remains EPC E, unless a valid exemption applies.

For property owners, the message is simple: don’t wait for regulation to force action. Plan ahead.

Myth 3: “MEES only affects large commercial buildings.”

The Government’s intended EPC B standard from 2031 focuses on privately rented non-domestic buildings over 1,000 square metres. Buildings below this threshold are intended to remain subject to the current EPC E minimum for now.

However, smaller commercial buildings should not be ignored.

The absence of a proposed EPC B deadline for smaller buildings does not mean they are exempt from current MEES requirements or that standards will never change.

The UK’s legally binding target to reach net zero by 2050 means reducing carbon emissions across the economy remains a long-term priority. Energy performance is also increasingly relevant to:

• Occupiers and their running costs
• Investors and asset managers
• Lenders and property finance
• Environmental, social and governance reporting
• Long-term property value and investment decisions

A smaller building with poor energy performance may face higher running costs, reduced occupier appeal or more expensive improvement work in the future.

Every building should be considered as part of the bigger portfolio picture.

Myth 4: “I can wait until MEES changes before taking action.”

You can wait, but that doesn’t necessarily mean you should.

Improving a building’s energy performance takes planning. Before making investment decisions, landlords should understand:

• Their current EPC rating and MEES position
• Potential improvement opportunities
• Likely costs
• Expected benefits
• The most practical route forward

Early planning gives owners time to assess their options, compare costs and consider improvements alongside other planned works, rather than reacting when deadlines approach.

For smaller buildings, it also avoids assuming that today’s minimum standard will remain unchanged indefinitely.

Planning ahead gives you more time to make informed decisions.

Myth 5: “The only goal is achieving EPC compliance.”

Compliance is important, but it is only part of the bigger picture.

An improved EPC rating does not automatically mean a building uses less energy in practice or that its running costs will fall by a particular amount.

The benefits of an improvement programme need to be considered alongside:

• Regulatory compliance
• Potential reductions in energy use and running costs
• Occupier needs and comfort
• Lower carbon emissions
• Long-term asset resilience

The right improvements will depend on the building, its existing systems, how it is used and what is practical and cost effective.

The future of commercial property will not just be about whether a building complies. It will also be about how well it performs.

Myth 6: “Commercial properties have to reach EPC C by 2027.”

The previously proposed 2027 EPC C milestone is not being taken forward.

The Government’s current intention is for privately rented non-domestic buildings over 1,000 square metres in England and Wales to meet EPC B from 2031, where cost effective, subject to secondary legislation.

For now, the current legal minimum remains EPC E for covered non-domestic rented property, unless a valid exemption applies. Scotland and Northern Ireland currently have no minimum EPC band for letting a commercial building.

It is important to distinguish between today’s legal requirements and the Government’s intended future changes. Property owners should not base investment decisions on outdated information about the 2027 proposal.

The Vital View

MEES should not be seen simply as a future compliance deadline. It is an opportunity to understand, plan and improve commercial property assets.

Whether you own a large office, industrial unit, retail property or smaller commercial building, understanding its current energy performance can help you make better-informed decisions about investment, improvement and future compliance.

Today’s regulatory threshold may not be tomorrow’s benchmark.

The question property owners should be asking is not only “Does my building comply today?” It is also “Is my building prepared for the future?”

At Vital, we help commercial property owners, landlords, investors and asset managers understand their current EPC position and identify practical opportunities to improve energy performance. Our commercial EPC service gives you the rating, and our EPC Plus report sets out a practical route to improving it.

Our approach is simple: Measure. Model. Improve. Comply.

Because the best time to plan for future requirements is before they become urgent.
