Commercial Ductwork Supply & Installation
Bespoke metal ductwork supply and installation for commercial and mixed-use buildings across London.
-
M&E coordination
We work with M&E teams and coordinated drawings to ensure the ductwork slots into the wider M&E programme without causing clashes or delays.
-
Pre-fabricated runs
Ductwork is fabricated off-site to agreed routes, reducing time spent working in occupied spaces.
-
Commercial-grade compliance
All installations meet relevant building and fire regulations for commercial and mixed-use premises.
Commercial ductwork and ventilation across London
Domani Ventilation Services supplies and installs commercial ductwork and mechanical ventilation for offices, mixed-use schemes, hospitality venues, education buildings, and leisure facilities across London and Greater London.
Over the past decade, overheating, indoor air quality, and noise requirements have made commercial ventilation more complex. Our role is to deliver ductwork and MVHR/MEV solutions that meet project specifications, programme dates, and regulatory obligations — without unnecessary cost or rework.
How commercial ventilation supports your business
Workplaces with high occupancy, equipment heat gains, or variable activity levels need ventilation that goes beyond opening windows. A correctly designed mechanical system can:
- Remove stale air, odours, and elevated CO₂ levels
- Recover heat from extracted air to reduce energy spend
- Improve comfort for staff, customers, and building users
- Support compliance with health, safety, and building regulations
We install ventilation for offices with IT load and heat gains, retail units with fluctuating footfall, gyms with humidity from showers and exercise areas, and food service spaces where kitchen extract and fresh air balance matter.

Ventilation solutions by sector
Workspaces and offices
HSE guidance expects enclosed workplaces to provide adequate fresh air. Our office ventilation packages commonly include MVHR units, heat exchange, fan coil distribution, and linear supply grilles — sized to manage CO₂, heat, and comfort across open-plan and cellular layouts.
Hospitality and leisure venues
Restaurants, cafés, and hospitality units need ventilation that manages kitchen fumes and odours without compromising the customer experience. We install MVHR systems with high-grade filtration (including F7 where specified), accessible plant locations, and acoustic treatment for quiet operation in dining areas.
Education settings
Schools, nurseries, and colleges benefit from ventilation that lowers CO₂ levels and replaces stale air with filtered supply air. Systems can include high-airflow floor-standing units, EC motors, heat recovery, summer bypass, and sensor options for demand-led operation.
Leisure centres and gyms
Gyms require ventilation that handles high occupancy, elevated CO₂, and humidity from changing rooms and showers. We specify MVHR systems with appropriate airflow capacity, heat recovery, and filtration to maintain a healthy environment for members and staff.
