SAP Calculations – Meaning

All new UK residential developments, conversions and some extensions are subject to a Standard Assessment Procedure (SAP). The SAP measures the energy efficiency of a building and is the basis of the Energy Performance Certificate (EPC).

This document is a building control legal requirement and must be completed before a property can be sold on or rented out.

SAP calculations are provided through our partner EAL Consultants, a well-established energy consultants with expertise in renewables and other low-carbon energy technologies.

SAP Calculations for New Builds

Any new building must have an SAP calculation to give to building control, which must comply with the minimum requirements in terms of Part L1A of the building regulations. The property cannot exceed the established carbon emission target – which may vary depending on where the building is and when construction began.

Additionally, if you’re constructing a property in England, your fabric must meet the necessary thermal performance level. EAL Consultants will help you deal with any problems that arise so you can achieve compliance quickly and efficiently. You’ll receive all the support you need throughout the process. Any questions you have will be answered by our expert partners.
