Prior to issuing the as-built SAP & EPC – a successful Air Leakage Test must have been conducted within the new building. During the design stage for your project, one part of the SAP Calculation will have determined the target Air Permeability Rate (APR) that must be achieved during the final Air Test itself. In essence, the lower the APR, the more stringent you will need to be during the construction phase in minimising air leakage points throughout the building.

At ATSPACE, our building compliance team look at the overall end-to-end process and our SAP assessors and Air Test engineers will always try to ensure that the client has a realistic target to hit come the Air Test day itself. Furthermore, ATPACE offers customers a discounted Air Test fee and the appropriate Air Test reports and certificates produced.

Once the Air Test has been successfully completed, you will be issued with the appropriate as-built SAP and EPC – after which the property can be signed off and sold legally.
