If you’re planning a new build or making major changes to a residential property, you’re probably aware that SAP Calculations are not optional — they’re a legal requirement under Part L of the Building Regulations. At EnviroSolution, we work with construction professionals across the UK to deliver fully compliant, accurate, and timely SAP Calculations that keep your project moving.
👉 SAP Calculations are essentially an energy performance assessment that determines how energy-efficient a residential building will be. If you’re submitting plans to Building Control, you’ll need these calculations completed before construction starts — and again at the end of the project for final sign-off and EPC generation.
Real-World Scenario: Mid-Sized Housing Developer
We recently supported a developer working on a 12-plot residential scheme in the Midlands. The client needed SAP Calculations for Building Control approval, and their in-house architect wasn’t familiar with the intricacies of U-values and renewable energy input. Our team quickly took their proposed spec and provided detailed SAP Calculations along with recommendations for cost-effective improvements to meet compliance. Result: no delays at sign-off, and each unit hit its required EPC rating first time.
What Construction Teams Need to Provide
To speed up the process, we typically ask for:
- Floorplans, sections, and elevations
- Construction details (U-values, materials)
- Heating system spec (boilers, underfloor heating, heat pumps, etc.)
- Lighting and ventilation details
If you’re missing any of these, don’t worry — we can advise and fill in the gaps with compliant assumptions or alternatives.
