New Build Standard Assessment Procedure (SAP) Calculations


Elmhurst Energy Services

Standard Assessment Procedure (SAP) calculations are a mandatory requirement for any new build dwelling. SAP is used to show compliance with Part L of the Building Regulations and is applied at the design stage of the build process.


SAP calculates the energy cost and carbon emissions generated to heat, light, ventilate and provide hot water to a building.


Elmurst's Services Team are fully qualified SAP Assessors and have been producing authorised SAP calculations since 1995. We provide the calculations for:

  • New Build Dwellings
  • Conversions
  • Extensions (where the amount of glazing is deemed high)


We pride ourselves in having good relationships with Building Control bodies. We provide advice and guidance on how to make your project comply in the most effective manner.

Our service has a rapid turn-around time, we are proactive in incorporating innovate materials and renewable energy sources into the calculations where and when required. Simply send us your plans and we'll do the rest!

Elmhurst Energy Services can also assist in standardising building specifications for larger developers i.e. a renewable energy strategy.
