SAP Calculations for New Builds


If you are a housing developer and would like to enquire about volume discount, please get in touch using the enquiry form on our Contact Us page and we will be pleased to see how we can meet your requirements.


New builds typically need a SAP assessment to be done at Design Stage, in order to demonstrate to building control that the proposed design will meet Building Regulations.  This provides an opportunity to review your design from an energy efficiency perspective, something that is increasingly important as we move towards Net Zero Carbon.  The As-Built stage demonstrates that the actual construction meets energy efficiency standards and takes into account any changes made between design and build stages.  UK Energy Assessors staff are qualified in architectural design as well as energy assessment, and we can advise on the most cost effective approach to achieving compliance for your project.


Background to SAP

SAP Calculations are a requirement of the Building Regulations and form part of the UK Government's plan to achieve Net Zero Carbon by 2050. SAP Calculations are required for new dwellings and certain types of conversion and extension. Part L1A of the Building Regulations for England and Wales set mandatory targets for the thermal performance of buildings and their associated carbon dioxide emissions. You will normally need a SAP calculation before commencing work in order to demonstrate to Building Control that your proposed design is compliance with the Fabric Energy Efficiency and Dwelling Emission Rate targets.


SAP Calculations are performed based on plans and specifications and do not require a site visit. Design stage calculations are required before commencing work and allow a Predicted Energy Performance Certificate to be produced - this is needed if you are going to market your development off plan. Our standard service for design stage SAP calculations includes offering suggestions to achieve compliance if your initial design proposal does not meet the required targets. As-built SAP calculations are required prior to selling the property and allow the final EPC to be generated. Our standard service for SAP Calculations covers both the Design and As-built stages of the process, but we can offer Design or As-built Stage only services where required.


We can typically turn around SAP Calculations within 48 hours of information being provided. The information needed to complete a SAP Assessment is described in more detail in our downloadable SAP Information Sheet. We are accredited to provide SAP Calculations and are able to offer this service on a nationwide basis. If you have a development that requires a SAP Assessment please get in touch using the contact form opposite. We will reply with pricing information and a firm quotation can provided once details of your development have been confirmed.
