The high temperatures recently experienced across the UK have placed extra pressure on many commercial kitchens, making effective ventilation and regular kitchen extract cleaning even more important. The Met Office reported that the UK provisionally broke its May and spring temperature record for the second day in a row, with 35.1°C recorded at Kew Gardens on 26 May 2026. This level of heat can intensify existing issues within extract systems, particularly where grease, carbon and debris have been allowed to build up.
For restaurants, hotels, pubs, schools, healthcare kitchens and other catering environments, this level of heat can make already demanding kitchen conditions even more challenging.
When temperatures rise outside, kitchens often feel the impact inside. Cooking equipment, grills, fryers and ovens already generate intense heat. If the kitchen extract system is restricted by grease, carbon or debris, it may struggle to remove heat, steam, smoke and grease-laden air effectively.
That is why regular Kitchen Extract Cleaning is so important.
Heat can make grease build-up more problematic
Grease naturally builds up inside canopies, filters, ductwork, fans and other parts of a kitchen extract system over time.
During periods of higher temperatures, grease deposits can soften, spread and become harder to manage. This can increase contamination within the system and make hidden areas more vulnerable to build-up.
Without professional Kitchen Extract Cleaning, grease deposits may continue to accumulate in areas that daily cleaning cannot reach. This can increase fire risk and create ongoing hygiene and compliance concerns.
Odours can become stronger in hot weather
Warm conditions can intensify odours from trapped grease, carbon, food residue and contaminated ductwork.
For busy commercial kitchens, this can affect more than just the back-of-house environment. Persistent odours may impact staff comfort, customer experience and the overall impression of the premises.
If unpleasant smells become more noticeable during hot weather, it may be a sign that the extract system needs inspection or cleaning.
Poor extraction can make kitchens harder to work in
A kitchen extract system should help remove hot air, smoke, steam and airborne grease from the cooking area.
However, when ductwork, filters or fans are affected by grease build-up, airflow can become restricted. During hotter UK weather, this can make the kitchen feel even more uncomfortable for staff.
Poor extraction can also place extra strain on mechanical components, making the system work harder than it should.
The implications for commercial kitchens
When heat, grease and poor extraction combine, commercial kitchens may face:
- Increased fire risk
- Stronger odours
- Reduced ventilation performance
- Hotter working conditions
- Greater strain on fans and equipment
- Hygiene concerns
- Compliance issues
- Potential disruption to daily operations
Why Kitchen Extract Cleaning matters during warmer weather
Professional Kitchen Extract Cleaning helps remove grease and contamination from the areas that standard daily cleaning cannot properly access.
This supports safer working conditions, improved airflow, reduced fire risk and better long-term system performance.
The recent high temperatures across the UK are a reminder that extract systems need to be properly maintained all year round, not just when problems become visible.
