Types Of Commercial EPC Assessments
Not all Commercial EPC assessments are the same. Different building types require different assessment levels depending on their size, complexity and installed building services. From small retail units and coffee shops to banks, offices, warehouses and industrial facilities, understanding the differences between Level 3 and Level 4 Commercial EPCs can help ensure the correct assessment is carried out. This section explains the various types of Commercial EPC assessments and how they apply to different commercial properties.
Types Of Commercial EPC Assessments - What Type Does Your Property Require?
What is the Difference Between a Level 3 (L3) and Level 4 (L4) Commercial EPC?
Commercial EPC assessments are divided into different accreditation levels depending on the complexity of the building being assessed. A Level 3 Commercial EPC is typically suitable for simpler buildings such as: Small offices Retail units Coffee shops Restaurants Small warehouses Standard commercial premises with simple heating systems A Level 4 Commercial EPC is generally required for more complex buildings containing features such as: Air conditioning systems Complex ventilation Multiple heating zones Larger commercial premises Mixed-use buildings More advanced mechanical services The correct level depends on the building itself rather than simply its size. An accredited assessor can confirm the appropriate level before the survey takes place.

What Buildings Require a Level 3 Commercial EPC?
Level 3 Commercial EPC assessments are usually used for simpler commercial buildings with straightforward construction and servicing arrangements. Examples often include: Shops Cafés and coffee shops Small offices Community buildings Workshops Basic industrial units Smaller retail premises These properties are generally assessed using SBEM (Simplified Building Energy Model) software and tend to involve less complex mechanical systems than larger commercial buildings. Level 3 EPCs are the most common type of commercial assessment for small and medium-sized business premises.

What Buildings Require a Level 4 Commercial EPC?
Level 4 Commercial EPC assessments are typically required for more complex buildings with advanced heating, cooling or ventilation systems. Examples may include: Banks Large offices Medical centres Hotels Multi-storey commercial premises Air-conditioned buildings Larger mixed-use developments These buildings often contain more sophisticated building services that require detailed modelling during the EPC assessment process. Because Level 4 properties are usually more complex, surveys and calculations can take longer than standard Level 3 commercial EPC assessments.

What is SBEM in a Commercial EPC Assessment?
SBEM stands for Simplified Building Energy Model. It is the government-approved software methodology commonly used to produce commercial EPCs for many non-domestic buildings. During the assessment, information about the building's construction, heating, cooling, lighting and ventilation systems is entered into the software to calculate the property's energy efficiency rating. Most Level 3 and many Level 4 commercial EPC assessments are produced using SBEM methodology.

Do I Need a Commercial EPC Before Selling a Commercial Building?
Yes. A commercial EPC is normally required before marketing a commercial building for sale. The certificate provides potential purchasers with information about the property's energy efficiency and must be available during the sales process. Most commercial properties, including offices, warehouses, shops and industrial buildings, require a valid EPC before being advertised. The certificate should be commissioned early to avoid delays once a buyer has been found. If a valid EPC already exists and is less than 10 years old, it may still be used for the sale, provided no significant alterations have been made that would affect the building's energy performance.

Do Air Conditioned Buildings Require a Different Commercial EPC?
Often, yes. Commercial buildings with air conditioning, comfort cooling or more advanced ventilation systems frequently require a higher level of assessment due to the increased complexity of the building services involved. Air conditioned offices, banks, medical buildings and larger commercial premises commonly fall within Level 4 accreditation requirements. Buildings containing cooling systems may also be subject to separate TM44 air conditioning inspection regulations depending on the size and output of the installed systems.

Can You Carry Out Commercial EPCs on Industrial Buildings and Warehouses?
Yes. Commercial EPC assessments can be carried out on a wide range of industrial and warehouse properties. This includes: Distribution warehouses Trade counter units Manufacturing buildings Storage facilities Industrial estates Hybrid warehouse/office premises The complexity of the assessment depends on the size of the building and the services installed within it. Large warehouses with office accommodation, heating systems or air conditioning may require more detailed modelling than basic storage buildings.
