We Can’t Get Building Regs Approval Without SAP Calculations!
You’ve secured planning permission, your architectural drawings are complete, and your contractor is lined up to start work next week. Everything is on track — until Building Control issues a warning: no SAP Calculations, no green light.
It’s a problem faced by many first-time and even experienced developers. You can’t legally start or complete a new build without producing Standard Assessment Procedure (SAP) Calculations. These reports demonstrate the energy performance of a proposed dwelling and are a requirement under Part L of the Building Regulations in England and Wales.
Why are SAP Calculations so important?
They assess how energy-efficient your design is, calculating carbon emissions, thermal performance, and energy usage based on insulation, heating systems, solar gains, ventilation and more. Without them, your project is technically in breach of Building Regs, and that means delays, fines, or a rejection at sign-off.
This is where EnviroSolution comes in. We provide fast, reliable SAP Calculations that ensure your project remains compliant from day one. We work closely with your architect or designer to review all specifications and ensure your planned build meets the necessary standards.
Our turnaround can be as quick as 48 hours, helping you avoid costly delays. What’s more, we don’t just produce numbers — we offer practical advice on how to improve your SAP rating cost-effectively if your design needs refinement.
Common red flags that might cause SAP issues include:
- Poorly insulated building fabric
- Lack of low-carbon heating solutions
- Excessive glazing or poorly oriented windows
- High air leakage rates
If your initial SAP rating doesn’t hit the required target, we work with you to adjust the specification. Whether it’s switching insulation type, improving airtightness, or installing PV panels, we help balance compliance with cost-efficiency.
When you choose EnviroSolution, you’re not just getting a report — you’re getting a partner in your project’s success. Our accredited assessors have worked on everything from one-off self-builds to 200+ unit developments, and we pride ourselves on clear communication, competitive pricing and a problem-solving attitude.
Don’t wait until Building Control stops your build. Be proactive. Get your SAP Calculations done early and avoid the stress of last-minute compliance hurdles.
