Commercial EPC Assessments

Comprehensive commercial EPC assessments for sales, lettings, compliance and asset management decisions.

Commercial EPC

What is a Commercial EPC?

A commercial EPC (Energy Performance Certificate) is a legally required assessment of a building’s energy efficiency. It is produced by an accredited assessor and provides an energy rating from A (most efficient) to G (least efficient), along with recommendations to improve performance and reduce running costs.

Commercial EPCs are tailored to the building type, age, construction and services. Unlike domestic EPCs, they consider more complex building systems such as heating, ventilation and air conditioning (HVAC), lighting, and larger floor areas. An EPC helps landlords, occupiers and investors understand compliance requirements and the building’s likely energy performance in use.

When Should You Instruct a Commercial EPC

Selling or Buying a Commercial Property

A commercial EPC is required during a sale and should be available early in the marketing process. It provides buyers with an overview of the building’s energy efficiency and can highlight potential compliance risks or upgrade costs.

Letting or Renewing a Lease

Landlords must provide a valid EPC when granting a new lease or renewing an existing one. An up-to-date EPC helps avoid delays, supports compliance with Minimum Energy Efficiency Standards (MEES), and gives tenants clarity on energy performance.

MEES Compliance and Improvement Planning

If a property has a low EPC rating, it may be restricted from being let unless exemptions apply. An EPC can help identify where performance improvements may be needed, supporting forward planning and reducing the risk of non-compliance.

Portfolio and Asset Planning

For property owners and asset managers, EPCs provide a consistent way to benchmark energy performance across a portfolio. This supports informed decisions on retention, refurbishment, disposals and long-term sustainability strategy.

What Our Commercial EPCs Cover

Our commercial building surveys include a careful, non-intrusive visual inspection of accessible areas at the time of inspection. Each report is clearly structured and supported by photographic evidence.

Building Details

We record key information including building type, age, use, floor area, construction type and zoning. This forms the basis of the EPC assessment and ensures the correct methodology is applied.

External Fabric

External walls, roof construction and glazing are considered as part of the energy model. These elements influence heat loss, insulation performance and overall efficiency.

Internal Areas

Internal layout, zoning and use are assessed where relevant. This helps determine how the building operates and how energy use is calculated within the EPC.

Heating and Hot Water

We review the building’s heating systems, fuel type, controls and hot water provision. The type and efficiency of these systems can significantly affect the EPC rating.

Lighting

Lighting type, controls and coverage are assessed, as lighting is a major contributor to energy consumption in many commercial buildings. Improvements here can often offer quick rating gains.

Air Conditioning and Ventilation

Where present, HVAC systems are considered including cooling, ventilation and controls. These systems can have a major impact on energy performance and EPC outcomes.

Understanding Commercial EPC Ratings

Our commercial building surveys use a clear priority-based system to highlight areas of concern. These ratings help clients understand which elements of the property are in satisfactory condition and which require attention, repair or further investigation, supporting informed commercial decisions.

A to C Ratings

Relatively energy efficient, typically associated with modern construction, efficient services and lower risk of regulatory or compliance issues.

D to E Ratings

Typical of many existing commercial buildings. An E rating meets the current minimum energy efficiency standard for lawful letting.

F to G Ratings

Poor energy efficiency. Properties in this range cannot be lawfully let under MEES without improvements or a registered exemption.

How EPCs Are Used

Our commercial EPC assessments are designed to support compliance and clear decision-making. They provide a valid certificate and practical recommendations, written in plain English and focused on outcomes.

Support Sales and Lettings

Provide the EPC required for marketing, sale or lease, helping avoid delays during a transaction.

Support Negotiations on Price or Terms

Use the EPC rating and recommendations to support informed negotiation and reduce uncertainty.

Plan Energy Efficiency Improvements

Prioritise upgrades that can improve performance, reduce running costs and support future-proofing.

Understand Compliance and Letting Risk

Identify where a low EPC rating may impact letting under MEES and plan the right next steps.

Support Asset and Portfolio Strategy

Benchmark EPC ratings across sites and plan improvements, refurbishment, retention or disposal.

Commercial Property Types We Assess

We provide commercial EPCs for a wide range of non-domestic property types across different sectors. Our EPC assessments are tailored to the building type, its use and the complexity of the services installed.

  • Industrial Units and Warehouses
    Including distribution centres, storage facilities and light industrial buildings.
  • Office Buildings
    From small office premises to multi-storey commercial offices.
  • Retail Units and Shopping Parades
    High street units, parades, showrooms and standalone retail properties.
  • Mixed-Use Properties
    Buildings combining commercial and residential elements (where an EPC is required for the non-domestic areas).
  • Small to Medium Commercial Premises
    Including owner-occupied and locally managed properties.

If you are unsure whether a commercial EPC is required for your building, our team will be happy to advise.

Frequently Asked Questions

A commercial EPC (Energy Performance Certificate) is a document that shows the energy efficiency of a non-domestic building. It provides an energy rating from A (most efficient) to G (least efficient) and includes recommendations to improve performance.

A commercial EPC is usually required when a property is:

  • sold

  • let

  • constructed

  • marketed for sale or lease

In most cases, the EPC must be available at the point the property is marketed, not after a buyer or tenant is found.

A commercial EPC is valid for 10 years, unless major changes are made to the building that could affect energy performance. If the EPC is still in date, it can usually be reused for future sales or lettings.

No. A commercial EPC is not a condition survey and does not report on defects, maintenance issues, or repair liabilities. It is an assessment of energy performance and focuses on construction elements and building services such as heating, cooling and lighting.

Commercial EPCs (also called non-domestic EPCs) are more complex than domestic EPCs. They account for:

  • larger floor areas

  • different building uses

  • more complex heating and cooling systems

  • ventilation and lighting performance

The methodology and assessment approach are different to a residential EPC.

We typically require access to the property and basic information such as:

  • floor areas and layout

  • building use and zoning

  • heating, hot water, ventilation and cooling systems

  • lighting type and controls

  • construction details (where available)

If you have plans, O&M manuals or specifications, these can help speed up the process, but they are not always essential.

This depends on the size and complexity of the building. As a general guide:

  • smaller premises may take around 1–2 hours

  • larger or more complex buildings may take longer, particularly where there are multiple zones or HVAC systems

We will confirm likely timescales once we understand the property type and size.

What is MEES and how does it relate to EPC ratings?

Yes — in many cases, EPC ratings can be improved. Common improvements include:

  • upgrading lighting to LED with controls

  • improving heating efficiency and controls

  • upgrading insulation (where applicable)

  • improving glazing performance

  • reviewing HVAC efficiency

The EPC recommendations report provides suggested measures, although the best improvements depend on the building type and intended use.

Commercial EPC costs vary depending on the size, layout and complexity of the property. A small single-unit building is usually quicker to assess than a large multi-storey or heavily serviced building.

We provide clear, tailored quotes once we know the property type, approximate floor area and location.
