Workplace Heat Risk Assessment Tool — HSE Six-Factor Framework

UK summers are getting hotter, and the law is clear: there's no maximum workplace temperature — instead, employers must assess heat as a risk and act on it. This tool helps you do exactly that, properly, in about ten minutes.

Built around the HSE's recognised six-factor thermal comfort framework, it walks you through a structured assessment of your workplace and produces a dated, professional record you can keep on file — the kind of documentation that shows you took your duty seriously.

What it does:

• Guides you through the six HSE heat factors — air temperature, radiant heat, air movement, humidity, clothing/PPE and work rate — plus exposure, hydration and workforce vulnerability
• Gives you a clear risk level (Low to Severe) with the reasoning shown — not a black box
• Generates a prioritised list of recognised control measures matched to your specific risks
• Flags higher-risk workers needing individual assessment, including the legal duty around pregnant and new mothers
• Includes a temperature log, an action checklist with sign-off, and a review-date prompt
• Prints to a clean, professional assessment record for your health & safety file

Why this beats a blank template: free templates hand you an empty form and assume you already know the answers. This tool walks you through the assessment, works out the risk level for you, and tells you which recognised controls apply to your situation — turning guidance into a finished, documented assessment.

This is an assessment aid, not legal advice or a guarantee of compliance. It helps you carry out and document your own assessment using the HSE framework; it does not replace a suitable and sufficient risk assessment or professional advice. Always verify current guidance at hse.gov.uk and acas.org.uk.

These templates, tools, apps, and e-learning courses are provided as general aids to help you build your skills and organise and document your own arrangements. They are not legal, professional, or safety advice, and they do not guarantee compliance with any law, regulation, or standard, nor any particular outcome.

You are responsible for deciding whether a template, tool, or course is suitable for your specific needs, workplace, activities, and circumstances, and for completing, adapting, and acting on it using competent judgment. Where the law requires a competent person, a formal assessment, a recognised qualification, or professional advice, you should obtain it.

Our e-learning courses are educational introductions intended to build general knowledge and good practice. Any certificate issued confirms completion of the course only; it is a certificate of completion, not an accredited or regulated qualification, and it does not certify competence to perform any specific task or role.

Where a tool or course performs calculations or produces figures, ratings, action levels, scores, or other results, those outputs are based on the information you enter and on general guidance, and are indicative only. They are not a site-specific assessment and must be independently checked by a competent person before you rely on or act on them.

Interactive tools and downloadable courses run entirely in your browser; they do not store or transmit the data you enter.
