Working Outdoors in Hot Weather: Know Your Rights and Stay Safe
Working outdoors in hot weather can pose serious risks to your health and safety. While many people welcome warmer temperatures, prolonged exposure to heat can lead to dehydration, heat exhaustion, sunstroke and even serious workplace accidents. If your job involves spending long hours outside, your employer has a legal duty to take reasonable steps to protect you from these risks.
Every summer we see reports of construction workers, roofers, road crews, agricultural workers and event staff becoming unwell after working in extreme heat. Although the UK does not have a legal maximum working temperature for outdoor work, employers must still assess the risks and put appropriate safety measures in place under the Health and Safety at Work Act 1974.
At Stonehewer Moss Solicitors, we’ve helped people who have suffered injuries because employers failed to provide basic precautions such as drinking water, adequate rest breaks or shaded areas. In many cases, these injuries could have been prevented with proper planning and sensible workplace practices.
In this article, we’ll explain your employer’s legal responsibilities, the dangers of working outdoors in hot weather, the practical steps employers should take to protect their workforce and what you can do if you’ve suffered an illness or injury because those duties were ignored.

Why Working Outdoors in Hot Weather Can Be Dangerous
Working outdoors in hot weather presents a range of health and safety risks that should never be underestimated. High temperatures, prolonged exposure to direct sunlight and physically demanding work can quickly lead to serious illness or increase the likelihood of workplace accidents. While the UK may not experience the same extreme temperatures as some countries, recent summers have shown that hot weather can still pose significant dangers for outdoor workers.
When the body becomes too hot, it struggles to regulate its core temperature. Without regular hydration, suitable rest breaks and opportunities to cool down, workers can experience symptoms ranging from mild heat stress to life-threatening heatstroke. Hot weather can also reduce concentration, slow reaction times and impair judgement, making accidents involving vehicles, machinery, ladders and scaffolding more likely.
Certain occupations are particularly vulnerable because employees spend most or all of their working day outside with little natural shade. These include:
- Roofers and construction workers who are exposed to direct sunlight and heat reflecting from roofing materials, concrete and steel.
- Road and tarmac workers who face additional heat generated by asphalt, road surfaces and heavy machinery.
- Festival and event staff who often work long shifts setting up equipment, managing crowds or providing security with limited access to shade.
- Agricultural workers and grounds maintenance teams who carry out physically demanding tasks in open fields or parks throughout the hottest parts of the day.
The risks are not limited to these industries. Landscapers, delivery drivers, utility workers, scaffolders, tree surgeons and anyone whose role requires prolonged outdoor work may also be affected during periods of hot weather.
Recognising the dangers of working outdoors in hot weather is the first step towards preventing avoidable injuries. Employers should carry out suitable risk assessments, monitor weather conditions and introduce practical measures to protect workers before temperatures become dangerous.
Employers’ Legal Responsibilities for Working Outdoors in Hot Weather
Employers have a legal duty to protect the health, safety and welfare of their employees, regardless of the weather conditions. Although there is currently no legal maximum temperature for working outdoors in the UK, this does not mean employers can ignore the risks posed by extreme heat. They must take reasonable steps to reduce those risks and provide a safe working environment.
The main piece of legislation governing workplace safety is the Health and Safety at Work etc. Act 1974. Under Section 2 of the Act, employers must, so far as is reasonably practicable, ensure the health, safety and welfare of all employees while they are at work. This includes assessing the risks associated with working outdoors in hot weather and implementing suitable control measures.
The Health and Safety Executive (HSE) also provides practical guidance on managing workplace temperatures and protecting employees working outdoors in hot weather. Employers should regularly review this guidance alongside their own risk assessments to ensure appropriate control measures are in place. You can find further information in the HSE’s guidance on thermal comfort in the workplace.
Employers should also comply with the Management of Health and Safety at Work Regulations 1999, which require them to carry out suitable and sufficient risk assessments. During periods of hot weather, these assessments should consider factors such as:
- The forecast temperature and humidity.
- The physical demands of the work being undertaken.
- How long employees are exposed to direct sunlight.
- Whether workers have access to drinking water, shade and rest facilities.
- Employees who may be particularly vulnerable, including pregnant workers and those with certain medical conditions.
If a risk assessment identifies a significant risk of heat-related illness or injury, employers should take practical steps to minimise that risk. Simply expecting employees to “get on with it” during extreme temperatures is unlikely to meet their legal obligations.
Employers who fail to manage the risks of working outdoors in hot weather may be found negligent if an employee suffers heat exhaustion, heatstroke, dehydration or an accident caused by the effects of excessive heat. Where an injury could reasonably have been prevented by appropriate safety measures, the injured worker may be entitled to claim compensation.
Taking sensible precautions not only helps employers comply with their legal duties but also reduces sickness absence, improves productivity and creates a safer working environment for everyone.
How Employers Can Reduce the Risks of Working Outdoors in Hot Weather
Preventing heat-related illnesses is far easier than dealing with the consequences after someone has become seriously unwell. By planning ahead and introducing practical safety measures, employers can significantly reduce the risks associated with working outdoors in hot weather while meeting their legal responsibilities.
Some of the most effective ways employers can protect outdoor workers include:
Provide Easy Access to Drinking Water
Workers should have continuous access to clean, cool drinking water throughout the working day. Employers should encourage employees to drink little and often rather than waiting until they feel thirsty, as thirst is often an early sign of dehydration.
Adjust Working Hours Where Possible
When practical, physically demanding tasks should be scheduled for the cooler parts of the day, such as early morning or later in the afternoon. Reducing strenuous activity during the hottest hours can significantly lower the risk of heat-related illness.
Provide Shade and Suitable Rest Areas
Employees should have somewhere cool to rest during breaks. This may include temporary shelters, canopies, air-conditioned welfare units or shaded indoor areas where workers can recover from prolonged exposure to the sun.
Increase the Frequency of Rest Breaks
During periods of high temperatures, employers should consider introducing more frequent breaks to allow workers to cool down and rehydrate. Short, regular breaks are often more effective than waiting for longer scheduled breaks.
Provide Appropriate Protective Clothing
Where PPE is required, employers should ensure it is suitable for hot weather wherever possible. Lightweight, breathable high-visibility clothing, wide-brimmed hats or neck protection and high-factor sunscreen can all help reduce the risk of sunburn and heat stress.
Train Workers to Recognise the Warning Signs
Employees and supervisors should understand the early symptoms of heat-related illness, including excessive sweating, dizziness, headaches, muscle cramps, nausea and confusion. Recognising these warning signs early allows action to be taken before the condition becomes a medical emergency.
Employers who take these simple but effective precautions are far better placed to protect their workforce during periods of hot weather. Regularly reviewing risk assessments and responding to changing weather conditions can help prevent avoidable injuries and ensure employees can work safely outdoors throughout the summer.
Can You Claim Compensation for a Heat-Related Injury at Work?
If you’ve suffered an illness or injury because your employer failed to take reasonable steps to protect you while working outdoors in hot weather, you may be entitled to make a personal injury claim. Every employer has a legal duty to provide a safe working environment, and failing to manage the risks associated with excessive heat could amount to negligence.
Not every heat-related illness will give rise to a compensation claim. However, where an employer has ignored obvious risks or failed to follow appropriate health and safety procedures, they may be held responsible for the harm caused.
Examples of situations where a claim may be possible include:
- Being required to work for long periods in extreme heat without access to drinking water.
- Not being given adequate rest breaks or opportunities to cool down.
- Being denied access to shaded or sheltered rest areas.
- Employers failing to carry out a suitable hot weather risk assessment.
- Suffering a fall or workplace accident after becoming dizzy or faint due to heat exhaustion or dehydration.
- Being required to carry out strenuous physical work during extreme temperatures without appropriate safety measures.
Heat-related workplace injuries can range from relatively minor cases of dehydration to serious medical emergencies requiring hospital treatment. In some cases, workers suffer long-term complications or sustain additional injuries following falls, vehicle collisions or machinery accidents caused by heat-induced fatigue or loss of concentration.
To bring a successful claim, it is usually necessary to show that your employer breached their duty of care and that this failure caused, or significantly contributed to, your illness or injury. Useful evidence may include medical records, accident book entries, photographs of the working conditions, weather reports, witness statements and any correspondence showing concerns about excessive heat.
In most cases, you have three years from the date of your injury to begin a personal injury claim. Seeking legal advice as soon as possible can help preserve important evidence and ensure your claim is started within the relevant time limit.
If you’re unsure whether you have a claim, speaking to an experienced personal injury solicitor can help you understand your legal options and whether your employer may be liable for your injuries.

Frequently Asked Questions
No. There is currently no legal maximum temperature for working outdoors in the UK. However, employers still have a legal duty under the Health and Safety at Work etc. Act 1974 to protect the health, safety and welfare of their employees. This means they must assess the risks posed by hot weather and take reasonable steps to reduce those risks, such as providing drinking water, rest breaks and access to shade.
You may be able to claim compensation if your employer failed to take reasonable precautions to protect you from the risks of working outdoors in hot weather and you suffered heat exhaustion, heatstroke, dehydration or another injury as a result. A specialist personal injury solicitor can assess whether your employer breached their duty of care and advise whether you have a valid claim.
Employers should carry out a suitable risk assessment and introduce practical measures to protect workers. This may include providing free drinking water, shaded rest areas, more frequent breaks, suitable protective clothing, sunscreen where appropriate, and adjusting working hours to avoid the hottest part of the day where reasonably practicable.
Employees should raise any health and safety concerns with their employer as soon as possible. While there is no automatic right to refuse to work simply because it is hot, employers must provide a safe working environment. If working conditions present a serious and imminent danger to your health or safety, you should seek advice and report your concerns immediately.
Heat exhaustion can cause heavy sweating, dizziness, headaches, muscle cramps, nausea, weakness and tiredness. If left untreated, it can develop into heatstroke, which is a medical emergency. Symptoms of heatstroke include confusion, a high body temperature, hot skin, rapid breathing and loss of consciousness. Anyone showing signs of heatstroke should receive emergency medical attention immediately.
