Industrial & Commercial Ventilation Systems
Ventilation is the process of introducing fresh air into indoor spaces while removing stale air. Mechanical ventilation is a system in a building that brings in "fresh" outdoor air and removes the "contaminated" indoor air.
There are four purposes of ventilation:
- Provide a continuous supply of fresh outside air.
- Maintain temperature and humidity at comfortable levels.
- Reduce potential fire or explosion hazards.
- Remove or dilute airborne contaminants.

If you’re looking to improve air quality, meet building regulations, or replace an ageing system, Inergy Group offers a complete ventilation service for commercial and industrial premises. We design, install, service and repair advanced heating and ventilation systems, helping businesses across the UK create safer, more comfortable, and energy-efficient workplaces.
From standalone commercial ventilation fans to integrated HVAC repair and upgrades, our solutions are built around your building and business needs.
Ventilation is the process of introducing fresh air into indoor spaces while removing stale air. For example, mechanical ventilation is a system in a building that brings in “fresh” outdoor air and removes the “contaminated” indoor air. Our team at Inergy are experts in recommending and installing a broad range of industrial and commercial ventilation systems.
Ventilation System Installation?
In a workplace, a ventilation system is used to control exposure to airborne contaminants. In addition, it is commonly used to remove impurities such as fumes, dust, and vapours to provide a healthy and safe working environment. Ventilation can be accomplished by natural means but is significantly more effective through mechanical tools (e.g. fans or blowers). In this case study we show how much we can improve the effectiveness of roof ventilation.
Commercial ventilation systems are similar in improving air quality and preventing space from becoming stale for either employees or customers. Still, there are other benefits that adequate ventilation can provide.
How Do Industrial Ventilation Systems Work?
Industrial ventilation systems are designed to move out (exhaust) and bring in (intake) a specific amount of air at a particular speed (velocity), which results in the removal of undesirable contaminants. While all ventilation systems follow the same basic principles, each system is explicitly designed to match the type of work and the rate of contaminant release at that workplace. Ventilation is considered an “engineering control” to remove or control contaminants released in indoor work environments. Therefore, it is one of the preferred ways to control employee exposure to air contaminants.
Industrial Ventilation Systems
General industrial ventilation reduces the concentration of air contaminants or controls the amount of heat that accumulates in hot industrial environments by mixing (diluting) the contaminated air with fresh, clean, uncontaminated air. This ventilation system is also known as dilution ventilation. Local exhaust ventilation captures contaminants at, or very near, the source and exhausts them outside.

Frequently Asked Questions
What does a heating and ventilation engineer do?
A heating and ventilation engineer designs, installs, maintains, and repairs systems that control the movement of air and regulate temperature in commercial and industrial buildings. This includes everything from ducted air handling and extraction systems to complex HVAC (Heating, Ventilation, and Air Conditioning) units.
At Inergy Group, our engineers work across sectors such as manufacturing, logistics, education, retail, and healthcare – helping clients maintain safe, comfortable, and energy-efficient environments. They also ensure installations meet compliance standards for air quality, energy use, and staff wellbeing.

Our full-service approach includes everything needed to deliver effective, compliant and long-lasting ventilation:
Free site survey and consultation to assess your building’s needs
Airflow testing and guidance on legal air change requirements
Bespoke system design, tailored to your layout, use, and budget
Installation by qualified HVAC and ventilation engineers
Commissioning and documentation for compliance
Planned maintenance and servicing contracts
Responsive HVAC repair support when you need it
We provide solutions for both new builds and retrofit upgrades, working around your operational needs.
How often should commercial HVAC systems be serviced?
We recommend servicing commercial HVAC and ventilation systems at least annually, with more frequent maintenance (e.g. quarterly) for:
Commercial kitchens and restaurants
Manufacturing plants or workshops with high air particulate output
High-occupancy buildings like gyms, schools, or medical centres
Regular servicing improves system efficiency, reduces running costs, and helps prevent breakdowns. It also supports compliance with workplace safety and air quality regulations.
How much does a commercial MVHR system cost?
The cost of a Mechanical Ventilation with Heat Recovery (MVHR) system depends on several factors. For commercial settings, prices typically start around £10,000, with larger or more complex installations ranging from £20,000 to £40,000+.
Pricing depends on:
The size and function of your building
Ducting layout and accessibility
Whether it’s a retrofit or new build
Level of control, zoning, and heat recovery required
For example, a full MVHR installation in a factory or large office may involve custom ductwork, extraction points, and integration into existing HVAC systems. We offer free consultations and site assessments to provide accurate proposals based on your requirements.
Can you help if our ventilation system breaks down?
Yes – we offer HVAC repair and emergency support for ventilation, heating, cooling, and integrated systems. Whether it’s a failed fan motor, poor airflow, or a complete system shutdown, our engineers are equipped to diagnose and resolve issues quickly.
We also offer servicing plans to help prevent breakdowns and extend the life of your system.
