Core installation

Full kitchen extraction system install — supply, fabrication, electrical and commissioning, carried out entirely by our own engineers. Everything below is included in the price unless stated under Exclusions.

Extraction System

Stainless steel extraction canopy hoodSized to cover the cooking line, grease baffles included
£8,400

304-grade stainless steel canopy, sized and positioned to cover the full cooking line confirmed at survey. 304-grade is the commercial kitchen standard — corrosion resistant, easy to clean, built to last. Grease baffles fitted as standard.

High-pressure centrifugal fan with inverter driveSpecified to the duct run's static pressure
Included

Fan selected to overcome the static pressure resistance of the surveyed duct run. The inverter drive gives variable speed control — turn it down during quieter periods to cut noise and energy use, up to full extraction during service.

In-line acoustic silencerFitted between fan and discharge point
Included

Attenuates fan noise at source. In a live trading environment, noise bleed from kitchen extraction into customer-facing space is a real concern — the silencer is specified to address this rather than relying on duct lagging alone.

Ductwork & Distribution

Ductwork fabrication & installFull run from canopy to discharge point
Included

All ductwork fabricated in-house to the route confirmed on site survey — including all bends, transitions and sections to complete the run. Exact length confirmed on installation day; the price reflects the surveyed estimate.

TR19-compliant access panelsInstalled at 2-metre intervals throughout the run
Included

A mandatory TR19 requirement — access panels must be present throughout the duct run for inspection and cleaning. Without them, the system cannot receive a TR19 certificate and your insurance may be at risk.

Rubber flexible connectionsAt canopy spigot and fan inlet/outlet
Included

Isolates vibration from the fan motor so it doesn't transmit through the ductwork into the building structure, and allows minor positional tolerance during installation.

Electrical & Ancillaries

Dedicated circuit breakerSupply and installation for the extraction fan
Included

Dedicated breaker supplied and installed as part of this contract. Connection point to the incoming electrical supply confirmed on site — any works to the incoming supply itself are by others.

Full fitting kitAll fixings, brackets, hangers and supports
Included

Everything needed to secure the canopy, ductwork and fan properly in position is included in the price — no day-one conversations about missing materials.

Commissioning & Handover

System commissioning & airflow balancingTR19 compliance certificate issued on completion
Included

Once installed, we run the system up, verify extraction performance at the canopy face, and set the inverter to the correct operating speed. The system is left working, not just installed — TR19 certificate issued same day.

As-fitted drawings & data sheetsIssued on completion, plus a full client walkthrough
Included

A record of the installed system — duct route, fan position, access panel locations — required for TR19 cleaning records and future maintenance. We walk you through the system before leaving: how to operate it, what to check, and your ongoing TR19 obligations.

Exclusions: building works and structural penetrations beyond those described, planning permission (we can advise), gas supply works, fire suppression, and electrical connection to the incoming supply (by others). Any work not explicitly listed above will be priced and confirmed in writing before commencement.

Additional works

Optional extras available alongside the core install — tick to add to your total.

All prices exclude VAT. Quote valid for 30 days from issue.

Your system will need regular TR19 cleaning

Once installed, your extraction system must be cleaned at TR19-compliant intervals to stay EHO-compliant and keep your insurance valid. We already know your system — ask us about a cleaning contract.
