Office vs Industrial: Why EPC Strategies Must Differ

One of the biggest mistakes commercial property owners make when planning energy efficiency improvements is assuming every building should follow the same strategy.

The reality is simple: not all commercial assets behave the same.

An office building and an industrial unit may both require Energy Performance Certificate, or EPC, improvement, but the pathway to achieving better performance can be completely different.

As landlords and investors prepare for the proposed Minimum Energy Efficiency Standards, or MEES, 2031 requirements, understanding these differences is important for effective capital planning, protecting asset value and avoiding unnecessary expenditure.

There is another consideration too. EPC and MEES planning should look at the whole portfolio, not just the buildings affected by the next regulatory change.

Why one EPC strategy does not fit all

Commercial portfolios often contain a mixture of offices, industrial units, warehouses and smaller commercial properties. A standard approach across every building can lead to poor investment decisions.

A strategy that works well for an industrial unit may deliver limited value in an office environment, while expensive interventions suitable for a complex office building may be unnecessary for a simpler industrial asset.

The starting point should always be understanding how each building operates and where the greatest opportunities exist.

Office buildings: more complex energy challenges

Office buildings can present a more complex route to EPC improvement because energy performance is often influenced by building services, how the space is used and occupier requirements.

Key considerations can include:

• Heating, ventilation and air conditioning, or HVAC
• Cooling demand
• Occupancy patterns
• Lighting
• Building controls
• Tenant comfort requirements

Depending on the building, improvements may include controls optimisation, HVAC or building management system upgrades, lighting improvements, fabric enhancements or electrification planning.

This does not mean every office requires major capital investment immediately. A detailed roadmap can help identify the most cost-effective pathway and allow improvements to be planned around refurbishment and lease events.

Industrial buildings: different opportunities

Industrial and warehouse assets often have a different energy profile. Depending on the building and its use, opportunities may include:

• Light emitting diode, or LED, lighting upgrades
• Improved controls
• Energy monitoring
• Heating optimisation
• Operational improvements

Lighting can be an important consideration in larger industrial and warehouse buildings, although the potential EPC benefit depends on the existing specification, building characteristics and other services included in the EPC assessment.

The important point is that industrial buildings are not automatically easier to improve. They simply present a different combination of opportunities and challenges.

Why this matters for MEES 2031 planning

The government has proposed that, from 2031, privately rented non-domestic buildings over 1,000 square metres would need to meet a higher energy efficiency standard of EPC B where cost-effective.

The current proposal is for buildings below 1,000 square metres to remain subject to the current EPC E minimum standard. These proposed changes are not yet law. However, smaller buildings should not simply be left out of long-term planning.

A building may fall outside the proposed 2031 EPC B requirement, but it remains part of the owner’s portfolio and may still present:

• Future compliance risk
• Higher running costs
• Carbon reduction opportunities
• Investment requirements
• Opportunities to coordinate improvements with planned works

The UK also has a legally binding target to reach net zero greenhouse gas emissions by 2050. For property owners, this means looking beyond today’s minimum requirements and understanding the energy performance of the whole portfolio.

Where the regulations actually stand

It is worth being precise here. EPC B from 2031 is a proposal rather than law, and it would apply to privately rented non-domestic buildings over 1,000 square metres in England and Wales, where cost-effective. It still requires secondary legislation before it takes effect. Below that threshold the minimum standard stays at EPC E, which is law today. Scotland and Northern Ireland have no minimum EPC band to let a commercial building at all.

Take a portfolio-wide approach

Rather than asking only which buildings need to reach EPC B, a better question is: what does our entire portfolio need to do to remain compliant, efficient and prepared for the future?

A portfolio-wide approach can help owners:

• Identify risks earlier
• Prioritise investment
• Avoid unnecessary expenditure
• Coordinate improvements with planned works
• Understand the likely cost of improving different assets
• Plan a longer-term pathway for energy and carbon performance

The proposed 2031 MEES changes may create a specific regulatory deadline for larger buildings, but good portfolio planning should look beyond a single deadline or floor-area threshold.

Moving beyond EPC compliance

The future of commercial property energy strategy is not simply about achieving a rating. It is about understanding:

• How each building operates
• Where investment creates the greatest value
• How improvements should be phased
• How individual assets fit into the wider portfolio

The question is no longer “What EPC rating do we need?” It is “What is the most effective strategy for this asset, and how does it fit into our wider portfolio?”

How Vital Direct can help

At Vital Direct, we help commercial property owners, landlords and asset managers develop tailored energy improvement strategies across different asset types and entire property portfolios.

Our EPC Plus advisory reports go beyond the certificate, identifying the most cost-effective pathway towards improved performance, EPC B readiness where relevant, all-electric operation and Net Zero in Operation objectives. If you need the certificate itself, our commercial EPC service covers assessment and lodgement.

Whether you own offices, industrial units, warehouses, smaller commercial properties or a mixture of asset types, the strategy should start with understanding the building, and the portfolio as a whole.

Because when it comes to energy performance, one strategy does not fit all.
