This product. Fitted by the team that designed it.
Most suppliers ship a fan and wash their hands. We fit and commission every unit we sell, so when something's not performing, we're not scrambling to read a subcontractor's install notes. One team, one accountability, one phone number.
- Manufacturer-trained install engineers
- Full DW/172 compliance pack on every install
- Next-day replacement parts if anything fails
- Service contracts and deep-clean schedules
- Emergency breakdown response within 24 hours
- Extended warranty on labour and parts

Compliance without the headache.
Every commercial extraction system in the UK has to pass muster with four different gatekeepers. We handle every one of them so you can focus on running your kitchen.
Environmental Health
DW/172-compliant design, grease management, and a signed commissioning report. We speak EHO.
Building Control
Fire damper placement, means-of-escape integrity and safe discharge. We liaise directly on your behalf.
Your insurer
Documented kitchen extraction with regular deep-clean schedule — the key to keeping your premium sane.
Landlord
Discharge at roof level, noise-compliant, vibration-isolated. Handover pack included for lease file.
What our clients say.
"Commercial Fan Pro specified and installed a full 4.8m twin-canopy system for our new Shoreditch site. DW/172 pack delivered, commissioned on time, and the kitchen is noticeably cooler than our last extraction setup."
"We were 10 days from opening when our extract fan failed. The Commercial Fan Pro team were on-site the next morning with a replacement Ventorn unit and commissioned within 24 hours. Saved our launch."
"Needed high-airflow extraction for 6 ghost-kitchen units in a tight footprint. They designed and installed a custom low-noise system that passed Environmental Health first time."
- For standard canopy hood replacements we can usually install within 2–4 weeks of sign-off. Emergency extract failures we can mobilise inside 72 hours. Full new-build fit-outs depend on fabrication time — typically 4–6 weeks.
- Yes, every system we supply is designed and commissioned to DW/172 (HVCA specification for kitchen ventilation systems). You get a full commissioning pack for Environmental Health and your insurer.
- Absolutely. About half our work is replacement or upgrade. We survey the existing ducting, motor, and any make-up air provision, then design the minimum-intervention solution.
- Our workshop is in North London but we install nationwide across the UK. Our engineers are mobile and regularly work from Edinburgh to Exeter.
- Yes — we offer scheduled deep-cleaning, filter replacement, bearing service and compliance inspection packages. Most clients renew annually.
- 2-year parts & labour warranty as standard. Extended warranties and service-level agreements available on request.
