With the UK expected to experience another heatwave next week, hospitality teams need to be prepared for the impact of extreme temperatures. 

For teams on the ground, this blog focuses on the practical daily habits that protect food quality, support staff wellbeing, and keep operations running safely during extreme heat. 

Why heatwaves increase risk across your operation 

Hot weather doesn’t just affect comfort – it directly impacts safety and performance. 

During a heatwave, businesses often face: 

• Increased risk of food spoilage 

• Greater strain on refrigeration and equipment 

• Higher likelihood of staff fatigue 

• Faster spread of bacteria if controls slip 

During busy summer periods, especially with increased footfall from major events, these risks can escalate quickly if routines aren’t followed consistently. These risks don’t happen suddenly – they build when small daily actions aren’t followed consistently. 

Protecting food safety in high temperatures 

Heat speeds up bacterial growth, which means food safety controls become even more critical. 

Stay on top of temperature control. 

Fridges and freezers are under more pressure in hot weather. 

• Monitor temperatures more frequently 

• Avoid overloading units 

• Keep doors closed where possible 

Small deviations can quickly become bigger risks. 

Review storage and handling practices 

Hot environments increase the risk of contamination. 

• Keep raw and ready-to-eat foods clearly separated 

• Minimise time food spends at ambient temperature 

• Ensure deliveries are checked and stored promptly 

Consistency is key – especially during busy service. 

 Supporting equipment performance under pressure 

Higher temperatures can impact how well equipment works. 

Watch for early signs of failure. 

Refrigeration, extraction, and cooking equipment can struggle in extreme heat. 

• Check units regularly throughout the day 

• Act on small faults before they escalate 

• Ensure maintenance schedules are up to date 

Reduce unnecessary strain 

Simple actions help equipment perform better: 

• Avoid blocking airflow around units 

• Schedule heavy usage where possible 

• Keep equipment clean and well maintained 

These steps help prevent breakdowns during peak periods. 

 Looking after your team 

Heat doesn’t just affect operations – it affects people. 

Staff working in kitchens, outdoor spaces, or busy venues are at increased risk of fatigue and dehydration. Supporting employees should be a priority during hot weather. 

Encourage regular hydration 

• Providing accessible drinking water stations 

• Encouraging staff to refill bottles before and during shifts 

• Reminding teams about hydration during pre-shift briefings 

• Keeping chilled water available in hot back-of-house areas 

• Checking that outdoor workers can access water without leaving their work area for long periods 

 Hydration is not simply a wellbeing benefit. Dehydration can affect concentration, decision-making and physical performance, all of which can increase risk during busy service. 

Supporting Vulnerable Guests 

Guests such as the elderly, pregnant women, young children and those with health conditions can be particularly vulnerable during a heatwave. It is important to support guests that are at a higher risk. 

• Ensure guests have access to drinking water 

• Create cooler seating areas  

• Move outdoor tables out of direct sunlight 

• Proper ventilation 

• Provide a menu with cool food items such as salad and fruit 

• Monitor indoor temperatures 

• Check in with guests regularly  

Recognise the signs of heat stress 

Teams should be aware of: 

• Dizziness or fatigue 

• Headaches 

• Difficulty concentrating 

Responding early helps prevent more serious issues. 

Heatstroke is more serious and requires urgent medical attention. 

Signs can include: 

• Confusion 

• Very high temperatures 

• Rapid breathing 

• Seizures  

Teams should know who to inform, where first-aid supplies are kept and when emergency assistance is required. 

Adjust where possible 

Small changes can make a big difference: 

Workloads  

Practical adjustments may include: 

• Scheduling additional staff for forecasted busy periods 

• Rotating employees between hotter and cooler work areas 

• Sharing physically demanding tasks across the team 

• Reducing unnecessary manual handling or heavy work during peak heat 

• Ensuring breaks are planned into the rota rather than left until service slows down 

 A well-planned rota protects employees from being overstretched and helps maintain consistent service for guests. 

Make breaks meaningful 

Breaks should give employees the opportunity to cool down, drink water and recover from the heat. 

During busy periods, staff may feel pressure to skip breaks or shorten them. Managers should actively check that breaks are being taken, especially by employees working in kitchens, outdoors or in heavier uniforms. 

Review uniforms and PPE 

Businesses should consider whether summer-appropriate alternatives are suitable without compromising safety or hygiene requirements. 

This could include: 

• Lightweight, breathable uniform options where appropriate 

• Breathable fabrics that still meet hygiene and presentation standards 

• Reviewing whether PPE is necessary for every task  

• Ensuring employees wearing PPE have more regular opportunities to cool down 

 Any changes should be practical, safe and suitable for the employee’s role. 

Improve airflow, ventilation and cooling 

Where possible, businesses should: 

• Check that ventilation and extraction systems are working effectively 

• Use air conditioning where available and ensure it is maintained 

• Keep airflow routes around units clear 

• Open windows and doors where safe and appropriate 

• Use fans to improve air movement in suitable areas 

• Close blinds or curtains in guest-facing spaces to reduce direct sunlight 

 Commercial kitchens require particular attention. Cooking equipment, ovens, grills, fryers and hot-holding units can make temperatures rise quickly, particularly during peak service. Effective extraction and airflow are essential to supporting safer working conditions. 

Where things can slip during a heatwave 

When temperatures rise and service is busy, standards can slip – not through lack of care, but through pressure. 

Common challenges include: 

• Missed or rushed checks 

• Increased reliance on memory 

• Delays in responding to issues 

• Reduced focus due to fatigue 

This is why heatwave safety is about keeping things simple, clear, and repeatable. 

Turning daily habits into consistent safety 

The most resilient businesses don’t introduce new processes during a heatwave. 

They focus on doing the fundamentals well, every time: 

• Clear routines that teams understand 

• Checks that are easy to complete 

• Accountability across every shift 

• Quick action when something isn’t right 

When these habits are in place, teams can manage pressure – even during peak summer trade – without compromising standards. 

Take action during the heatwave 

As temperatures rise, now is the time to focus on the basics: 

• Are food safety checks being completed consistently? 

• Is equipment being monitored closely? 

• Are your teams supported and able to take breaks? 

• Are routines simple enough to follow under pressure? 

Because safe operations during a heatwave don’t happen by chance –
they happen through consistent daily habits.
