Off-Plan Calculations – Pre-Construction Heat Loss Modelling
Planning an eco-conscious building or renovation? Our off-plan calculations give you early-stage performance insights to inform design, material choices, and system sizing—long before construction begins.
Services
Heat Loss from Plans – Detailed thermal modelling from architectural drawings and specifications.
Early Design Input – Optimise layout, insulation, glazing, and building orientation for best thermal performance.
ASHP & Low-Carbon Heating Guidance – Early recommendations on zoning, system design, and positioning of air source heat pumps.
Compliance & Outputs
Detailed modeling in line with BS EN 12831 and MCS requirements.
Performance and noise estimates to support early contractor and supplier engagement.
Provides a firm foundation for budgeting, system procurement, and EPC/SAP preparation.
Future Homes Standard Ready
The UK Future Homes Standard (FHS) will require all new homes built from 2025 to produce 75–80% fewer carbon emissions compared to current regulations. This means:
No gas boilers in new builds
Heat pumps and other low-carbon systems as the default choice
Higher efficiency building fabric and insulation standards
Our off-plan heat loss calculations are designed with these future regulations in mind, helping developers and architects meet FHS targets today. By aligning your project with upcoming standards, you avoid costly redesigns, reduce compliance risk, and ensure homes are market-ready for a low-carbon future.
Benefits of Off-Plan Heat Loss Surveys
Cost Control – Identify design risks early, avoid oversizing, and streamline procurement
Reduced Rework – Minimise design changes and wasted materials during construction
Collaboration – Improve coordination between architects, developers, and M&E teams
Future-Proof – Ensure compliance with the Future Homes Standard and long-term energy efficiency
Get Expert Input Before You Build
Our off-plan heat loss calculations provide the foundation for efficient, compliant, and cost-effective heating system design. Developers, architects, and contractors across the UK trust us to deliver accurate results that save time and money.
