Picture this nightmare scenario. Your busy restaurant kitchen during evening rush, when suddenly flames burst from your exhaust hood. The fire spreads through grease-covered ducts faster than you can blink. Your staff screams as smoke fills the dining room and customers flee in panic. Every day you delay proper commercial kitchen exhaust hood cleaning in London puts your business at serious risk of this exact disaster.
1. Fan Services

This London-based company has been keeping kitchens safe since 2015 with their impressive 4.9-star customer rating. They really know their stuff when it comes to complete HVAC solutions for commercial spaces.
I heard from one restaurant owner whose breakfast service almost got ruined when their extraction fan died. Fan Services jumped into action within minutes and had a replacement installed the same day. That kind of emergency response saves businesses thousands in lost revenue.
Their commercial kitchen cleaning team handles everything from full system checks to gas interlock testing. They measure airflow to make sure everything works properly and remove dangerous grease buildup from inside your kitchen ducts. The technicians can also reposition canopies and boost extraction speeds to get rid of cooking fumes faster.
They balance negative pressure and install make-up air systems so your kitchen stays comfortable while meeting all safety rules.
