SAP Assessment

How does it work?

The Standard Assessment Procedure (SAP), assesses the energy and carbon performance of the whole building. During each assessment an assessment of the Fabric Energy Efficiency (FEE), Environmental Impact and Dwelling Emission Rating is undergone, and a SAP calculation is accumulated.

What is the Difference between a SAP assessment and SAP rating?

A SAP rating is part of each SAP assessment and is calculated through evaluating the expected energy costs of the ventilation, space heating, water heating and lighting within the property. Each SAP score is rated between 1-100, the higher the number the better the energy consumption.

Is a SAP assessment only required for new builds?

All new build dwellings require a SAP assessment and all existing dwellings will require an RDSAP (reduced data standard assessment procedure) if any extensions etc. are being undergone.

Who can complete a SAP Assessment?

Only registered SAP assessors can complete a standard assessment procedure.

What is the difference between SAP and EPC?

An ‘as built’ SAP calculation determines the A-G performance ratings that are shown on an EPC. As of 2008, all domestic new builds must have an Energy Performance Certificate (EPC), which will be included within a Home Information Pack, to be used when the property is sold.
