SAP L1a new build

Specialists in SAP calculations for new build dwellings

New residential buildings must comply with Part L1a of Building Regulations, which stipulates that SAP assessments must be undertaken, and submitted to Building Control prior to the start of any works on site. All SAP assessments must be undertaken by accredited Energy Assessors.

Ecoflow are accredited Energy Assessors and therefore well equipped to deliver this service, having carried out hundreds of SAP calculations for individual house builders, property developers, housing associations and building contractors throughout the UK.

SAP L1a Calculations provided by Ecoflow include:

Design Stage SAP Calculations
TER / DER calculations
Predicted Energy Certificate
U-value calculations
As Built Energy Performance Certificate (EPC)
Lodgement of EPC with Landmark Registry

At the end of your new-build project the final as-built SAP report is then issued for submission to Building Control together with an On Construction Energy Performance Certificate (EPC) which is required by Building Control prior to the issue of the completion certificate and also for the subsequent sale or let of the property. We also lodge the EPC on the National Landmark Register.
