SAP Calculations for Conversions: Ensure Your Project Meets Building Regulations
Why You Need a SAP Calculation for Building Conversions
When converting an existing building into residential use, it’s crucial to ensure that the building complies with current energy efficiency standards under Part L of the Building Regulations. A SAP Calculation for Conversion assesses the energy performance of your building after conversion, ensuring that it meets the required energy efficiency standards and remains comfortable and cost-effective for future occupants.

​
Speed Up Building Control Sign Off
Whether you’re converting a commercial building into residential flats or transforming a barn into a modern home, our SAP calculations for building control help you meet the stringent requirements for energy performance. Without a Part L Compliant SAP Calculation Building Control will not sign off on your project, meaning you can’t legally occupy or sell the property.
​
​
Improve Your Building's Energy Efficiency and Save Money
In a building conversion, factors such as insulation, window quality, and heating systems must be carefully evaluated to meet energy efficiency requirements. A SAP Calculation for Conversion evaluates:
-
U-values of the building materials used in walls, roofs, and floors.
-
The efficiency of heating systems and hot water provisions.
-
The building’s air tightness and overall heat loss performance.
By improving these areas before the conversion is completed, you ensure that your building complies with Part L and achieves a favorable SAP rating and saves you money.
