☀️ Expecting a heatwave or sustained high temperatures? Mention the forecast and work type — we'll include hydration breaks, shade provision, work rescheduling and heat illness monitoring specific to your site.
Legal requirements for hot weather and heatwave working
Under the Health and Safety at Work etc. Act 1974, employers have a general duty to ensure, so far as is reasonably practicable, the health, safety and welfare of employees — this extends to protecting workers from the effects of extreme heat while working outdoors. Regulation 3(1) of the Management of Health and Safety at Work Regulations 1999 requires a suitable and sufficient risk assessment of all workplace hazards, including seasonal and weather-related risks such as heatwaves.
While there is no statutory maximum working temperature in the UK, HSE guidance makes clear that employers must assess the risk of heat stress, dehydration, sunburn and heat exhaustion for outdoor workers, and introduce controls such as rescheduling strenuous tasks, providing shade and free drinking water, and allowing more frequent rest breaks. Employers must also consider the Provision and Use of Work Equipment Regulations 1998 where PPE or clothing affects heat tolerance.
Outdoor workers face elevated long-term UV exposure risk, and HSE data links this to increased rates of skin cancer among outdoor occupations. A documented risk assessment covering the summer months demonstrates compliance and protects your workforce during the highest-risk period, typically June to August.
How it works
1. Describe the work
Tell us the type of outdoor work, workforce size, expected temperatures, and any vulnerable workers. Mention if the site involves working at height, as we can tailor controls for combined risks such as heat and fatigue affecting footing and concentration.
2. Let the app take the strain
Anyrisks produces a fully written, UK-compliant hot weather and heatwave risk assessment referencing the Management of Health and Safety at Work Regulations 1999 and HSE heat stress guidance.
3. Instant download and use
Download as PDF and Word. Share it with your workforce, pin it in the site office, or file it for your summer compliance records. £29, no subscription.

Frequently asked questions
Is there a legal maximum temperature for outdoor working in the UK?
No — unlike the minimum temperature guidance for indoor workplaces, there is no legal maximum temperature for outdoor work in the UK. However, Regulation 3(1) of the Management of Health and Safety at Work Regulations 1999 requires employers to assess and control risks from heat stress, dehydration and sun exposure during hot weather and heatwaves.
What counts as a heatwave for risk assessment purposes?
The Met Office defines a UK heatwave as three consecutive days where daily maximum temperature meets or exceeds a location-specific threshold, typically 25 to 28 degrees Celsius. For risk assessment purposes, any sustained period of high temperature combined with physical outdoor work should trigger additional controls.
Does this cover sun exposure and skin cancer risk?
Yes — prolonged UV exposure is a recognised occupational health hazard for outdoor workers. HSE guidance confirms that outdoor workers are at increased risk of skin cancer, and the assessment includes controls such as shade provision, sunscreen, and clothing cover.
Is heat stress a RIDDOR-reportable condition?
Heat stress incidents resulting in loss of consciousness, hospital treatment or incapacity for more than seven days may be reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR). Your assessment should include monitoring and first aid response procedures to reduce this risk.
Who needs a hot weather risk assessment?
Any employer or self-employed person whose workers carry out physical tasks outdoors — construction, landscaping, agriculture, events, roadworks or deliveries — should have a documented hot weather risk assessment covering the summer months, typically June to August.
Does it cover vulnerable workers?
Yes — describe if your workforce includes pregnant workers, those with underlying health conditions, or workers unacclimatised to heat, and the assessment will include specific controls under the duty to protect vulnerable individuals.
Can it be used alongside an outdoor event risk assessment?
Yes — if you are running an event, this assessment complements an outdoor event risk assessment by focusing specifically on heat-related hazards for staff, stewards and contractors working outside.
How long does it take to generate?
Under 2 minutes. Describe the outdoor work, expected conditions and workforce, and Anyrisks produces a complete, regulation-referenced hot weather risk assessment instantly.
