SAP (Standard Assessment Procedure) is the official method in the UK for conducting energy efficiency assessments to measure a residential property’s energy performance and ensure compliance with Building Regulations Part L. Without these assessments, your project cannot gain approval from Building Control.
The SAP calculations take into account various factors, including the construction type and specific u-values for walls, roofs, floors, and windows. Moreover, the efficiency of heating, hot water, and ventilation systems is also evaluated.
Are you planning a new build, conversion, or extension?

Provide your drawings along with any specific preferences you may have for your development. These will be reviewed, and an initial energy efficiency assessment will be conducted to evaluate how your proposed specifications align with Part L compliance of the Building Regulations. This assessment will examine the design, layout, building fabric, and systems utilised for heating, ventilation, hot water, and lighting within the dwelling.
The findings from this initial SAP assessment will be analysed, and if necessary, improvements will be identified to enhance energy efficiency. Clear and practical recommendations will be made to ensure that the dwelling achieves compliance with Part L of the Building Regulations.
Throughout the construction phase, support will be provided to seamlessly integrate energy-saving measures into the delivery process. Upon completion of the build, an 'As Built' SAP calculation and an On Construction Energy Performance Certificate (EPC) will be issued to reflect the energy efficiency of the dwelling.
You can rest assured that Energy Planning and Compliance Solutions will work closely with you, your architect, and/or your builder to ensure everything runs smoothly, helping you achieve full compliance and secure Building Control approval without delays.
