Frequently Asked Questions
General & Compliance
Do you install both extraction and fresh air systems?
Yes, we provide full commercial kitchen ventilation setups, including extraction and fresh air supply systems. This ensures proper airflow, staff comfort, and full compliance with health and safety regulations.
How long does installation take?
Most standard installations are completed in 1–3 days. We’ll provide a clear timescale after a site visit, along with a no-obligation quote.
Do you provide servicing and maintenance?
We do. We offer service packages that include filter changes, fan maintenance, airflow checks, and compliance reviews to keep your system running efficiently.
Are your systems compliant with UK regulations?
Absolutely. All our installations meet DEFRA and DW/172 standards. We also install fire-rated ducting, motorized fire dampers, and supply full certification for local authority approval and insurance.
Do you offer system upgrades or replacements?
Yes. We upgrade existing systems with ESP units, carbon filters, silencers, fans, and other components to improve performance, meet new regulations, or reduce noise and odours
Fan Noise & Performance
Why is my kitchen extraction fan so noisy?
This could be caused by grease buildup, worn bearings, damaged blades, or poor installation. We can diagnose the issue and offer servicing or replacement to reduce the noise and improve airflow.
How can I reduce fan or duct noise?
Solutions include installing silencers, vibration isolators, upgrading the fan, and ensuring the system is properly balanced between extraction and fresh air. We assess all these during your site survey.
Can you replace or upgrade a noisy fan?
Yes. We install quieter, energy-efficient fans with proper anti-vibration mounts and duct silencers to reduce noise and meet your kitchen's airflow needs.
Technical & Design
What’s the difference between ESP units and carbon filters?
ESP units remove grease, smoke, and fine particles.
Carbon filters remove odours.
They're most effective when used together in heavy-duty or odour-sensitive environments.
How do I know what airflow my kitchen needs?
We calculate airflow requirements during the site survey based on your equipment, kitchen size, and usage. This ensures compliance and efficient operation.
What areas do you cover?
We’re based in london and provide ventilation services across the London counties.
Do I need a fresh air system if I already have extraction?
Yes. Without fresh air, your kitchen will suffer from negative pressure, poor airflow, and possible appliance issues. It's also a legal requirement for most commercial kitchens.
Do I need fire-rated ducting and fire dampers?
If the ductwork passes through multiple fire compartments, levels, or exits the building, fire-rated ducting and motorized dampers are required. We’ll advise and install them where needed.
