Get your project off to the right start. We provide the vital calculations and statements required to secure planning permission and satisfy Part L Building Regulations.
Before a single brick is laid, your building's energy strategy must be proven. Designing and planning calculations form the critical foundation of modern construction.
From SAP and SBEM calculations ensuring Part L compliance, to complex overheating assessments (TM59) required by local planning authorities — we model your project to guarantee it meets both national laws and local targets efficiently.
Browse our full suite of pre-construction compliance modeling. We provide everything required to secure your planning approval and pass Building Control regulations.
Standard Assessment Procedure modeling for new homes to prove compliance with Part L energy laws. Essential for residential Building Control approval.
Explore ServiceSimplified Building Energy Model for commercial projects like shops, schools, and offices. Ensures your non-domestic project meets Part L regulations.
Explore ServiceClear, detailed energy strategies required for planning permission. We ensure your project meets local authority energy-saving targets and carbon reduction policies.
