FAQ
What information do you need from me to start the SAP calculations?
I need your architectural floor plans, sections, and elevations (in PDF or DWG format), along with details about your insulation, window specifications, and heating systems.
What happens if my building design fails the initial SAP calculation?
Don’t worry. If it fails, I will analyze the report and provide clear, actionable recommendations—such as upgrading insulation or adjusting your heating specs—to help your project pass.
Do these calculations comply with current UK Building Regulations?
Yes. All assessments are performed according to the latest Part L (Conservation of fuel and power) requirements for building control approval.
Can you help size my Air Source Heat Pump (ASHP) based on the report?
Yes. I can perform a detailed room-by-room heat loss analysis to determine the exact kilowatt (kW) capacity required for your specific ASHP installation.
