New-Build Energy Assessments

As accredited Energy Assessors and Low Carbon Consultants, we are fully qualified to produce energy assessments on both residential (SAP) and commercial (SBEM) developments. 

From planning to practical completion working with us will ensure that your project complies with the relevant energy and carbon requirements of the Building Regulations.

Building Regulations

Under Section 6 (Scotland) and Part L1A (England & Wales), all new buildings (domestic and non-domestic) require energy assessments to be carried out before work can start on site.

An energy assessor is therefore required to perform an assessment of the design using a prescribed methodology to demonstrate compliance with the regulations. The results of this assessment must then be submitted to Building Control as part of the building warrant application process. The Building Regulations outline different procedures for assessing energy in domestic and non-domestic buildings as described below.

Domestic (SAP)

The Standard Assessment Procedure (SAP) is adopted by Government as the UK methodology for calculating the energy performance of dwellings.  

The SAP rating is based on the energy costs associated with space heating, water heating, ventilation and lighting, less cost savings from renewable technologies.

Non-domestic (SBEM/DSM)

The Simplified Building Energy Model (SBEM) is the equivalent methodology for calculating energy performance in non-domestic buildings in the UK. For more complex buildings, approved dynamic simulation modelling (DSM) software is used.

Both methodologies compare CO2 emissions, where the emissions from the ‘actual’ building must not exceed those which are calculated for the ‘notional’ (benchmark) building to comply with the Building Regulations.

What happens if compliance is not achieved?

Following a review, should compliance not be achieved, Carbon Futures will provide advice and solutions to ensure compliance is accomplished in the most cost-effective manner.

When this process is complete, we will issue a series of reports that will be passed onto Building Control for approval to allow construction to begin on site.

How can we help?

Carbon Futures are qualified and experienced energy assessors who take responsibility for ensuring compliance with the Building Regulations without the need for further scrutiny by Building Control. 

We always recommend that you engage with us early in the design process to ensure compliance is achieved as smoothly and efficiently as possible.


McTaggart Construction has commissioned Carbon Futures on numerous projects of varying scale and complexity.   They provide our team with a variety of energy and sustainability related construction solutions to enhance the energy performance and improve the delivery of our residential developments.  Their professional and innovative approach has proven to be an extremely valuable service to our company and our clients.  We would be happy to recommend their services to others and we look forward to working with them on future projects.
