Thermal modelling designed for approval, not rework

If your scheme needs to demonstrate overheating risk or energy performance, then yes. It is commonly required for Part O compliance, planning conditions, and higher-risk or complex developments.

We assess against TM52, TM59, TM54 and Part O, depending on your project type and stage. This ensures your design aligns with current UK guidance.

TM52 is typically used for non-residential buildings, while TM59 is focused on residential overheating risk. The methodology and pass criteria differ, so the correct one depends on your scheme.

Yes. Thermal modelling supports Part L by testing real building performance, helping identify risks that SAP or SBEM alone may not highlight.

Most standard assessments are completed in 3–7 working days. More complex or large-scale schemes may take longer depending on scope and design stage.

Costs vary based on size, complexity, and level of detail required. Simple assessments are typically lower cost (from £300, depending on scope), while dynamic simulation modelling for large schemes will require a tailored quote.

Yes. Our reports are aligned to recognised methodologies and are structured to support Building Control and SAP assessor review.

You receive a clear report outlining: Compliance results Identified risks Practical recommendations where needed The aim is to support approval, not just provide data.

Yes. We provide practical design advice to improve performance, whether that is glazing, shading, ventilation, or building fabric changes.

Yes. We can respond to queries from Building Control, planners, or design teams to help move your project forward.

Yes, and it should be. Early modelling helps avoid costly redesigns and supports better decisions at planning and concept stages.

Where useful, enevo can align thermal modelling with SAP, air testing, acoustics and wider compliance inputs to avoid conflicts later in the project.

Yes. All modelling is delivered by our in-house building physics team, ensuring consistency, quality, and accountability.

We support residential, commercial, education and complex schemes, including high-rise and modular developments.

Yes. We can assess condensation risk alongside thermal modelling to ensure buildability and long-term performance.

For higher-risk buildings, thermal modelling often forms part of the wider compliance evidence needed at Gateway 2, particularly where overheating risk must be demonstrated.

Yes. We regularly support projects with tight deadlines and can prioritise assessments where required.
