ERS has delivered hundreds of SBEM calculations and commercial EPC’s over the years, helping building developers, owners and managers meet compliance standards and boost building efficiency.


SBEM is the method of calculating a buildings energy and carbon performance for all commercial or industrial scale buildings.

As part of the UK Part L Building Regulations, all new build structures and some extensions require SBEM calculations. They should be submitted at the same time as your Building Control Application.

ERS are experienced in SBEM calculations and delivering the 'pass' rating that you require. We use a computer software-based model called SBEM (developed by BRE) to establish energy ratings.

Part L Building Regulations changed on 6th April 2014 which, in effect, means that all new non-domestic buildings have to reduce carbon emissions by 9% below 2010 regulations.

ERS have a deep knowledge of energy efficiency and renewable energies gives us the experience to help you get the most from your advisory report. We ensure that you've always got someone to turn to for energy advice and to assist the implementations required between the 7 year reporting stages.

EPC’s (Energy Performance Certificates):

An Energy Performance Certificate (EPC) is similar to the certification found on many domestic appliances. They are used to demonstrate the energy rating of a building.

An energy performance certificate displays the energy efficiency of a building on a scale of band A (most efficient) to band G (least efficient). EPC's are required by the Energy Performance of Buildings Directive applicable to England and Wales, and they are accompanied by advice on how to improve the buildings energy efficiency.

We have a dedicated team of fully qualified assessors and we provide free technical advice and an instant quote over the phone. ERS have many years of experience in the application of both commercial and residential Energy Performance Certificates (EPC’s).

Our consultants can review your plans, provide initial advice for free, conduct the calculations and issue certification at the best industry rates.

We will need some information from you to assist the calculations. Please call 01865 378885 or fill our form, we'll be more than happy to talk you through the best approach to your SBEM or EPC requirements.
