Commercial (Non Domestic) Energy Performance Certificates (EPCs)
and Display Energy Certificates (DECs)

The Government timescale for the introduction of Commercial (Non Domestic) Energy Performance Certificates required for all buildings that are newly constructed, sold or leased is as follows:

• Buildings over 10,000 sq meters - 1st April 2008

• Buildings over 2,500 sq meters - 1st July 2008

• Buildings less than 2,500 sq meters - 1st October 2008

In addition a Display Energy Certificate (DEC) will be required for all Public Buildings from 1st October 2008.

Only Commercial (Non Domestic) Energy Assessors trained in the SBEM methodology and licensed by an authorised accreditation body will be able to produce and lodge EPCs for commercial buildings.

The SBEM (Simplified Building Energy Model) is government's approved method for demonstrating the building's compliance with Building Regulations and provides an analysis of a building's energy consumption and carbon dioxide emissions.

The site survey requires the Commercial Energy Assessor to capture a significant amount of data about the building including measurements, general details about the use of each part of the building, heating, hot water and ventilation systems, windows, lighting, building fabric and other details.

3Counties can offer EPCs for commercial properties by our accredited Commercial Energy Assessors as follows:

Level 3

Simple, small existing buildings with commonly occurring characteristics without centralised air conditioning plant. These often include simple heating systems <100kw, natural ventilation and simple cooling systems.

Level 3 does not include the assessment of new build from plans. Examples are converted domestic buildings, doctors surgeries and small shops.

Level 4

New and existing larger buildings with more complex systems and likely to include centralised air conditioning plant.

Fees – Commercial EPCs and DECs

Fees will largely depend on the size of the property, the complexity and number of "zones" that it comprises.
