Our Ventilation Services:
Design & Installation
Bespoke ventilation systems that ensure a continuous airflow while removing contaminants, moisture, and excess heat. Our systems are tailored to your specific building requirements, ensuring compliance with all industry regulations and environmental standards.
Maintenance & Repairs
Regular maintenance and routine inspections are crucial to ensure your ventilation system continues to perform efficiently and maintains healthy air. Our expert technicians carry out checks for issues like airflow restrictions and swiftly repair any blockages, or mechanical faults.
Heat Recovery Ventilation (HRV/MVHR)
Energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a cross flow or counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow. HRV provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling) requirements for many applications including vehicles.
Increased Comfort & Productivity.
Regulates temperature and humidity levels, creating a comfortable working environment for employees and customers. Studies show that good ventilation can positively impact concentration and cognitive function, leading to increased productivity.
Improved Indoor Air Quality.
Removes airborne contaminants like dust, pollen, bacteria, and harmful chemicals, leading to cleaner air for occupants. Most building codes mandate adequate ventilation to ensure occupant health and safety.
Energy Efficiency.
Properly designed ventilation systems can optimise heating and cooling needs by managing air exchange, potentially lowering energy consumption.
Benefits for Commercial Ventilation
Commercial Ventilation Use Cases:
Restaurants & Kitchens
High-quality extraction and fresh air systems for food safety compliance.
Offices & Retail
Air circulation solutions to improve employee productivity and customer experience.
Healthcare Facilities
Maintain sterile environments with specialised filtration systems.
Hotels & Gyms
Ensure clean air for guests with smart ventilation systems.
Reduced Maintenance Costs.
By removing contaminants from the air, industrial ventilation can minimise the need for cleaning and equipment maintenance.
Temperature Regulation.
Helps maintain a comfortable temperature range within the facility, improving worker comfort. Reduces exposure to harmful airborne contaminants like dust, fumes, chemicals, and gases, minimising the risk of respiratory illnesses and occupational diseases for workers.
Fire Prevention.
Proper ventilation can help control the spread of flammable vapors, reducing fire hazards.
Benefits for Industrial Ventilation
Industrial Ventilation Use Cases:
Factories & Warehouses
Large-scale ventilation for heat dissipation and improved worker safety.
Production Facilities
Custom systems for climate-sensitive manufacturing environments.
Data Centres
Controlled airflow to prevent overheating of IT equipment.
Cold Storage Facilities
Maintain consistent air exchange for temperature stability.

HRV extracts stale indoor air and replaces it with fresh outdoor air, transferring heat in the process to significantly reduce HVAC energy usage. ERV systems additionally manage humidity, making them ideal for gyms, kitchens, and humid commercial environments. These systems can recover 60–95% of heat, resulting in lower energy bills and enhanced indoor air quality—while helping businesses meet UK Part F ventilation standards.

DCV uses CO₂ and occupancy sensors to adjust airflow based on actual usage—reducing ventilation when rooms are empty and increasing it when space is occupied. This smart system can cut ventilation-related energy usage by 20–40%, while ensuring good air quality and compliance with Part F regulations.

Ventilation systems—including ducts, filters, fans, and controls—should be professionally inspected at least once per year. Regular maintenance prevents blockages, ensures airflow is optimal, reduces noise, and extends equipment lifespan—key for both air quality and energy efficiency.
Typical mistakes include poor ductwork planning, inadequate sealing (leading to energy loss), incorrect system sizing, and failing to comply with Part F requirements. Proper planning and professional installation are essential to prevent airflow inefficiencies, excessive noise, and maintenance hassles later on.
Leakage in duct systems leads to wasted energy, compromised air quality, and noisy operation. Ensuring tight sealing reduces heat loss and avoids unnecessary strain on HVAC equipment—improving both performance and efficiency.
Costs depend on building size, system type (HRV, ERV, or DCV), and complexity of ductwork. A small office may only require a few thousand pounds’ investment, while larger commercial or industrial facilities will be higher. Modern systems are highly energy efficient and often pay for themselves through reduced energy bills and improved air quality.
Most small to medium installations can be completed within a few days. Larger or more complex systems may take longer, but our engineers plan works to minimise disruption—often scheduling installations outside of peak operating hours to keep your business running smoothly.
