SAP Calculations for Conversions
SAP Calculations are required for many conversion projects in the UK, ensuring that newly created dwellings meet the energy‑efficiency standards set out in Part L of the Building Regulations. Whether you’re converting a commercial space, subdividing an existing property, or changing the use of a building, SAP assessments demonstrate that the upgraded fabric, heating systems, and ventilation strategy achieve the necessary compliance.
Ensuring Compliance When Buildings Take on New Life
At Stanley Sustainability, we provide SAP calculations tailored for conversion and change‑of‑use projects — from office‑to‑residential schemes to barn conversions and beyond. By modelling energy performance with precision, we help you demonstrate compliance with Part L of the Building Regulations, secure Building Control approval, and optimise design choices for unique building types.
Our service is ideal for developers, architects, and others navigating the complexities of repurposed buildings.
What We Deliver
🧮 Specialist SAP Modelling – Assessments adapted to the quirks of conversions and mixed‑use projects

🔧 Design Guidance – Advice on insulation, heating, and renewables to achieve compliance cost‑effectively
