About

SAP calculations are required to demonstrate compliance with Building Regulations Part L.

We assess how your building will perform based on:

  • Fabric performance (walls, roofs, floors)
  • Glazing and solar gain
  • Heating and hot water systems (including heat pumps)
  • Ventilation strategy (including MVHR)
  • Renewable technologies such as solar PV

We provide:

  • As-designed SAP calculations for Building Control
  • As-built SAP & EPC on completion

 We don’t just produce the numbers — we work with you to get the design right.
