Our Expertise

We specialise in SAP and RdSAP calculations for a wide variety of building types, including:

  • New Builds
  • Conversion Projects
  • Extensions
  • Existing Buildings
Why Choose CAESL for Your SAP & RdSAP Assessments?
  • Personalised Expertise: You’ll have a dedicated energy assessor who will understand your project’s specific needs and provide tailored, efficient, and friendly service.
    Free U-Value Calculations: Benefit from complimentary U-value assessments for walls, floors, and roofs, enhancing energy efficiency.
  • Cost-Effective Compliance: We aim to achieve energy compliance without introducing costly options or delays to your build timeline.
  • Quick Turnaround: We understand the importance of meeting deadlines, and we deliver efficient results even under tight schedules.
Key Elements Assessed in SAP Calculations:

When conducting SAP calculations, we assess multiple factors contributing to energy consumption and carbon emissions, such as:

  • Thermal efficiency of walls, floors, and roofs
  • Performance of windows and doors
  • Boiler efficiency
  •  Secondary heating systems
  •  Renewable energy integration
  •  Building air tightness
Our Process: From Design to Completion
  • Initial Design Review: We assess your architectural plans to ensure compliance with Part L of Building Regulations.
  • Design Stage SAP Calculations: Our team evaluates compliance with energy regulations (Part L1A for new builds and L1B for conversions/extensions).
  • Design Review & Adjustments: We propose practical adjustments to achieve compliance in a cost-effective manner.
  • Predicted EPC & SAP Calculations: We provide design-stage SAP calculations and a predicted Energy Performance Certificate (EPC) for building control submission.
  •  As-Built SAP Review: Near project completion, we ensure the built structure matches the SAP design specifications. If necessary, we re-calculate to maintain compliance.
  • Final SAP & EPC Submission: After the final review, we issue and lodge the as-built SAP calculations and EPC with the relevant authorities
RdSAP Assessments for Existing Properties

We also offer RdSAP assessments to provide accurate EPC ratings for existing properties, whether you’re selling, renting, or aiming to improve energy efficiency. Our team conducts on-site evaluations, assessing key factors such as insulation, heating systems, and windows to generate a precise EPC for your building.

 

SAP vs. RdSAP: What’s the Difference?
  • SAP Calculations: Required for new builds, conversions, and extensions, ensuring compliance with energy regulations during design and construction phases.
  • RdSAP Calculations: Designed for existing buildings, offering a streamlined assessment of energy performance to generate EPCs for established structures or energy upgrades.
