When this service may be useful
An overheating assessment helps test whether internal conditions are likely to be acceptable under the agreed scenarios. It is useful before glazing, shading, ventilation and servicing decisions are fixed.
Energy & sustainability
Overheating Assessments
Specialist assessment of overheating risk and potential mitigation.
How the work is approached
Specialist input develops the agreed model from building geometry, orientation, glazing and occupancy assumptions. Results are reviewed with the design team, with mitigation or further scenarios tested where included in the scope.
What you receive
You receive the agreed assessment, assumptions and design recommendations. The modelling reflects a defined design version; later changes may require reassessment before the recommendations can be relied on.
What we need to start
Building geometry, glazing, orientation, uses and servicing assumptions.
We review the site, proposal and planning stage to agree the appropriate scope. Specialist surveys and assessments are coordinated where needed.
How our planning consultancy process worksILLUSTRATIVE REPORT PREVIEW
Overheating Assessment
Front cover and contents page examples. The document structure is tailored to your instruction, site and relevant planning requirements.
What the report should contain
This outline explains the purpose of each section. The final contents depend on the agreed scope, available evidence and requirements of the local planning authority.
Document control & executive summary
Project details, reference, revision, date, author, reviewer and a concise summary of the key findings.
Proposal, rooms & assessment scope
Identify the dwellings or spaces assessed and the purpose of the study.
Methodology & acceptance criteria
State the chosen assessment approach and relevant guidance.
Model geometry, fabric & glazing
Document building inputs, shading and room selection.
Weather & occupancy assumptions
Record weather files, gains, schedules and assessment scenarios.
Ventilation & opening constraints
Explain air movement assumptions and security, noise or air-quality restrictions.
Baseline results
Present room-level performance against the selected criteria.
Passive mitigation & revised results
Test shading, glazing, ventilation and other appropriate measures.
Residual risk & design commitments
Explain conclusions, limitations and the measures the final design must retain.
Appendices & evidence register
Index relevant plans, photographs, calculations, surveys and source documents; include only the evidence relevant to this instruction.

Overheating assessments FAQs
Clear answers to help you plan your next step.
Still have a question?
Tell us about the site and we will confirm what is needed and what it should cost.
Make an enquiryCan you test alternative design options?
Yes, where additional scenarios are included in the scope. We agree the baseline design, assumptions and options to be tested, such as shading, glazing or ventilation changes, before modelling proceeds.
What information should I provide to get started?
Building geometry, glazing, orientation, uses and servicing assumptions.
How is the fee for this service confirmed?
The price shown is a starting estimate for the stated scope. We review the site, proposal, available information and required deliverables, then confirm the fee, exclusions and programme in a written quotation before appointment.
How do your specialists work together on a project?
We bring the relevant planning consultants and specialist providers into a coordinated project team. They work from an agreed brief and current proposal, with dependencies and design changes discussed across disciplines. Each consultant remains responsible for their own professional advice and agreed deliverables.
PART OF A COORDINATED APPOINTMENT
Your specialist evidence, connected.
This service can form part of a wider coordinated planning appointment. We bring the relevant consultants together to work alongside your design team, discuss assessment findings and identify how recommendations affect other reports and the proposal.
Your fee proposal confirms who prepares each document, the information it relies on and the limits of the instruction. A report provides evidence for the council’s assessment; the planning decision remains the council’s. Explore how our consultants work together or discuss the team your project needs.
