Choosing the right canopy size depends on the type and volume of cooking you’re doing. Factors like heat output, appliance layout, and kitchen dimensions all play a role. A canopy that’s too small won’t capture smoke and grease effectively, while an oversized one can be inefficient and costly to run.

Cleaning frequency varies based on usage, but most busy kitchens require professional duct and canopy cleaning every 3 to 6 months. Regular maintenance isn’t just about hygiene—it’s essential for fire safety and staying compliant with insurance and local regulations.

In many cases, yes—especially if you’re installing external ducting or operating in a residential or mixed-use area. Local councils often have strict requirements around noise, odour control, and visual impact, so it’s worth checking early to avoid delays. We can guide you on this. 

UK regulations require adequate ventilation to remove heat, smoke, and airborne grease. Systems must comply with standards such as DW/172 and health & safety guidelines. Proper installation and ongoing maintenance are key to meeting these obligations.
