    SAP Assessments
    Standard Assessment Procedure, or SAP as it is more commonly known, is the Government’s method for measuring the energy rating of a building.

    SAP calculates a dwelling’s CO2 emissions, along with likely energy costs for space, water heating and lighting per square metre, producing a score between 1-100. The higher the number, the more energy efficient the property is.

    Build Aviator SAP Assessment Service takes your plans and provides you with a product specification. We provide a list of materials required, meaning your assessment has been undertaken using actual u-values rather than notional values. This offers a significantly more accurate representation of the energy rating of your dwelling

    We ensure all the products listed are locally available saving time with material procurement

    We include our Registered Construction Details (RCDs) into your assessment, providing you with build details and points to watch to minimise thermal bridging at junctions. These RCDs have been approved by Local Authority Building Control

    Along with a full SAP report, you’ll also receive an on-site support pack containing: a SAP summary, product specification with associated U-values, RCDs and support documents for end of build testing.
