How Does It Work and What’s The Process?

Doing  SAP calculations for extensions is slightly different than SAP calculations for New Builds or even SAP calculations for conversions.

Although the principles are the same there are different methods of compliance and also we are adhering to Part L1B of the building regulations.

Don’t worry, we’ve done thousands of SAP calculations for extensions and we will ensure everything runs smoothly for your extension.

We will assess your extension from the plans and specification you or your architect provide us.

From our experience, the vast majority of projects we assess achieve a pass first time. However, if a pass is not achieved we shall put forward cost effective solutions to achieve a pass.

We can suggest a number of measures such as:

  • Increase in insulation or quality of insulation
  • Higher performing glazing
  • Improvements to the existing dwelling
