From 2006, legislation has been in place enforcing the requirement for all new dwellings to comply with current SAP Regulations. SAP is the Government's Standard Assessment Procedure for calculating the energy rating of dwellings. Carpenter Davies Partnership are qualified SAP Assessors and can complete your SAP Calculations.

In general terms, this necessitates the production of Standard Assessment Procedure (SAP) calculations by a qualified SAP Assessor, showing the comparison between the Dwelling Emission Rate (DER) and Target Emission Rate (TER).  Approved software has to be used to perform the assessment.

From 2008, an EPC has also been a legal requirement and Carpenter Davies Partnership Ltd. are qualified to carry out this service.
