FAQ
What do I need to provide for my SAP calculation and EPC?
Simply provide your architectural drawings (floor plans, elevations, sections), site layout, and construction specifications (wall, roof, floor insulation type). If you have specific details for a heat pump, solar PV, or timber frame build, include those as well to ensure total accuracy.
Do you handle both design stage and as-built SAP calculations?
Yes. I cover the entire pipeline for your peace of mind. I perform the initial design stage SAP calculation to clear your building control hurdles before construction starts, and then issue the final as-built SAP calculation and legal EPC certificate once the building work is completed.
Will this assessment ensure my project achieves full Part L compliance?
Absolutely. Every assessment is meticulously modeled using industry-approved software to guarantee your new build, HMO conversion, or house extension meets strict UK building regulations. If your initial design fails, I will give you clear, cost-effective solutions to pass.
Can you model calculations for complex extensions and loft conversions?
Yes. I specialize in highly glazed extensions, complex loft conversions, and detailed property conversion projects. I run precise calculations to balance excessive glazing or tricky insulation layouts, keeping your design compliant without sacrificing your architectural vision.
How fast will I receive my completed compliance documents?
Standard domestic projects are delivered within 48 to 72 hours. If you are facing an urgent building control deadline for an apartment block or residential development, choose my express delivery gig extra at checkout, and I will fast-track your project to the top of my queue.
