SAP Calculation

The Potton SAP Calculation service is available to all self builders whether you are building with Potton or not.

SAP is the Standard Assessment Procedure (SAP) and is the UK Government's recommended method system for measuring the energy rating of residential dwellings. 


How SAP works

SAP works by assessing how much energy a dwelling will consume, when delivering a defined level of comfort and service provision. The assessment is based on standardised assumptions for how you live in your home. This enables a like-for-like comparison of dwelling performance. Related factors, such as fuel costs and emissions of carbon dioxide (CO2), can be determined from the assessment.

The latest revision of SAP came into force in April 2014 with the updated building regulations amendment to Part L of the Building Regulations for England. The updated SAP is expected to deliver a 6% improvement in new dwelling energy performance.

What is an Energy Performance Certificate?

Energy Performance Certificates (EPCs) is an assessment and certification of the performance of your new home. The EPC contains information about a property’s energy use and typical energy costs and recommendations about how to reduce energy use and save money. An EPC is required for all newly built homes gives a property an energy efficiency rating from A (most efficient) to G (least efficient).

Helping you to achieve compliance

To ensure that your home complies with the SAP calculation and that the Energy Performance Certificate (EPC) can be issued at completion of your build, the building fabric must be constructed following the agreed insulation strategy and to the required standard of workmanship.

To help you achieve this, Potton can also supply a complete insulation package to ensure that your entire building envelope performs to optimum standards and in full compliance with the SAP assessment for your home.
