SAP Calculations for Energy-Efficient Homes

To give you the most accurate SAP assessment and helpful advice, we need a clear picture of your design.  Ideally, this means providing us with detailed, up-to-date drawings (electronic format is preferred) and any accredited construction details you have.

The more information we have, the better we can understand its energy performance potential. This typically includes:

• Architectural Drawings: Floor plans, sections, and elevations to understand the building’s layout and dimensions.
• Site Orientation: A site plan showing the position of existing elements and the orientation of the proposed building to assess solar gain and potential overshadowing.
• Construction Specifications: Detailed information about the construction materials and methods for existing walls, new structures, roofs, and floors, including insulation types and thicknesses.
• Window Specifications: Details about the type of glazing (single, double, triple), frame materials, and dimensions of all windows.
• Heating System Information: Specifications for both primary and secondary heating systems, including their efficiency ratings and any controls.
• Renewable Technology Details: If your project incorporates renewable energy sources like solar panels or heat pumps, we’ll need information about their type, capacity, and integration into the building’s systems.

Providing this information upfront allows us to conduct a more thorough and accurate SAP assessment, leading to optimised energy performance and a smoother compliance process.

Comprehensive Documentation: We provide all the necessary SAP calculation documentation required for full compliance with the Building Regulations, from the initial Design Stage (Predicted Energy Assessment or PEA) through to the final On Construction stage (On-Construction EPC or OC-EPC).

Expert Guidance for Success: If your project needs a little boost to meet energy efficiency targets, we offer tailored advice and recommendations to ensure a pass every time.

Dedicated Support: We’re with you every step of the way, offering clear communication and answering any questions you may have throughout the SAP assessment process.

Quick Turnaround: We understand that time is of the essence in construction projects. That’s why we prioritise efficiency and offer quick turnaround times for your SAP calculations.

Seamless Collaboration: We’re happy to liaise directly with your builder, architect, or Building Control Officer during our site visit, ensuring a smooth and hassle-free experience.

Holistic Building Performance: We understand that a successful project goes beyond just energy efficiency. That’s why we offer a range of complementary services, such as air tightness testing, sound insulation testing, and ventilation assessments, to ensure your building performs optimally across multiple aspects.

SAP (Standard Assessment Procedure) calculations are the UK government’s approved method for assessing the energy performance of new dwellings. They predict energy use and carbon emissions, resulting in an Energy Performance Certificate (EPC) rating.

SAP calculations are mandatory for new dwellings to demonstrate compliance with Part L of the Building Regulations (England & Wales) or Section 6 (Scotland). They’re essential for obtaining building permits and ensuring your project meets energy efficiency standards.

Ideally, SAP calculations should be integrated into the early design stages of your project. This allows you to optimise energy efficiency from the outset and avoid costly modifications later. However, a final SAP assessment is also required upon completion for compliance and to generate the official EPC.

Multiple factors impact your SAP rating, including the building fabric (insulation, windows, airtightness), heating and hot water systems, ventilation, lighting, and renewable energy installations.

While it’s best to optimise energy efficiency during the design phase, some improvements can be made after construction. However, these can be more costly and disruptive. A professional SAP assessor can advise on potential retrofitting options.

The cost varies depending on the complexity and size of your project. At Focus360 Energy, our SAP Calculation services start from £80 + VAT, and we offer same-day quotes for your convenience.

Our team of accredited assessors provides accurate and comprehensive SAP calculations, ensuring compliance and offering expert guidance on optimising energy efficiency.

We offer a range of services to support your building’s overall performance, including air tightness testing, ventilation assessments, thermal bridging analysis, and sound insulation testing.
