commercial epc

There are 2 levels of commercial EPC, which one your building requires depends on the following:

Level 3

This refers to buildings with typical features in terms of construction materials, layout, and design. Think of small shops, restaurants, or offices. Total heating system capacity should be less than 100kW, this generally means smaller boilers or individual heating units. If the building has air conditioning, its total cooling capacity should be under 12kW. This typically covers single units or small split systems.  

Level 4

These buildings have features that are not typical of standard commercial structures. This could include unusual shapes, unique construction materials, or specialised internal layouts. Level 4 buildings often have more sophisticated heating, ventilation, and air conditioning systems. This might involve Heating systems greater than 100kW, cooling systems greater than 12kW, multiple zones with different temperature controls and air handling units.
