Why it is Required
A SAP (Standard Assessment Procedure) energy assessment is a required calculation for all new build homes in England and Wales. It measures the predicted energy performance of a dwelling and is used to demonstrate compliance with Part L of the Building Regulations. The SAP calculation informs your Energy Performance Certificate (EPC) and is an essential part of the documentation needed for Building Regulations sign-off.
At APT UK, we provide SAP assessments that are accurate, clearly documented, and delivered in a timescale that keeps your project on track.

Why a SAP Assessment is Important
Getting your SAP assessment right from the outset saves time and avoids complications later. A well-prepared SAP calculation helps you understand the energy performance of your design before construction begins, identify whether any changes are needed to meet compliance targets, and produce the documentation required by building control.
It also provides the information needed to issue the final EPC upon completion — a legal requirement before any new home is sold or occupied.
