Non Domestic Building Energy Rating


From the 1st of January 2009 a Building Energy Rating (BER) certificate is compulsory for all non domestic buildings being offered for sale, rent or lease.

(Certain exemptions apply click here)


The BER is an indication of the energy performance of the building. It covers energy use for space heating and cooling, water heating, ventilation and lighting calculated on the basis of standard operating patterns.


The BER is intended to give prospective buyers and tenants information about the energy performance of buildings. The rating also gives landlords/vendors an incentive to upgrade the energy performance of the building by giving visible credit to superior standards.


The rating is expressed in the form of performance bands rated from A to G








































A building with an A grade will be the most energy efficient and will hence have the lowest energy bills. For all existing buildings there is no pass/fail grade.


The BER certificate is accompanied by an "Advisory Report" setting out recommendations for cost-effective improvements to the energy performance of the building. However, there will is no legal obligation on vendors or prospective purchasers to carry out the recommended improvements.


Capstone Energy Management specialize in Non Domestic Building Energy Ratings.

Our assessors use the national calculation methodology software SBEM to calculate the BER and generate the advisory report. For new build projects this software can also be use to check for Part L compliance.


The SBEM software calculates the energy consumption and CO2 emissions associated with a standardized use of a building.
