SAP Calculations for new build dwellings in England

All new buildings in England and Wales are required to have a Standard Assessment Procedure (SAP) calculation, which quantifies energy performance in terms of heating, lighting, and ventilation. The calculation also considers the fabric and structure of the building, the type and efficiency of insulation, and any renewable technologies installed.

Why SAP Calculations Are Required
​
SAP calculations are used to demonstrate compliance with Part L1 of the Building Regulations. They ensure your new dwelling is energy-efficient, comfortable, and compliant with UK standards.

Importance of SAP at the Design Stage

It is highly recommended to carry out the 
SAP calculation during the design stage of your project. Doing so allows:
  • Early identification of potential energy efficiency issues
  • Design adjustments before construction begins
  • Avoidance of costly changes once building work is underway

By addressing energy performance requirements early, you can save time, reduce costs, and ensure smooth building control approval.

How Our SAP Calculations Work

All our SAP calculations are carried out 
off plan, so we do not carry out site visits. To complete the calculation, we ask you to provide:
  • Floor plans and building layouts
  • Building specifications
  • Construction notes

Providing this information upfront ensures a smooth and accurate SAP calculation process.

As Built EPC

Once construction is complete, we can produce an 
As Built EPC (On Construction EPC) for your new build dwelling. This confirms the building meets energy performance standards and fully complies with building regulations.

Our Commitment to Sustainability

We are an 
eco-aware company committed to reducing carbon emissions in the construction and property industry. By helping new builds achieve energy efficiency targets, we support sustainable housing design and the adoption of renewable technologies.
