Rather than bring in multiple companies to design, supply, and install your new ventilation system, it pays to use just one reliable, reputable contractor.

Our in-house team of experts will handle every stage of the process for you, with clear communication every step of the way. This saves you time, resources, and money and means you can focus on what you do best – growing your business.

Ventilation Design and Consulting

Where do you begin when it comes to designing a ventilation system? It’s vital to select something that aligns with the size, needs, and age of your building.

We specialise in designing efficient, fully bespoke ventilation systems. We’ll visit you on site, answer your questions, and take measurements. Our CAD and IESVE specialists will then handle the design of your system, ensuring it operates in line with UK requirements.

We also offer independent consultancy services, ensuring your existing ventilation system operates as it needs to, and recommending how you can optimise it.

Keeping Your Ventilation System Low-Cost and Efficient

To ensure your air is fresh and free from contaminants, it’s essential to check your ventilation system regularly. We provide comprehensive testing and reporting, so you can take steps to improve reliability and efficiency as required.

We also offer independent validation services, checking your new or modified ventilation system to ensure it complies with health and safety standards.

We measure the flow rate of air leaving your ventilation system to ensure optimal air quality and comfort.

We measure the air speed to make sure your ventilation system complies with Building Regulations and does not use excess energy.

We measure differential pressure in your ventilation system to identify any issues like blocked filters.

We test the air leakage rate of your ventilation system to ensure your system runs efficiently and you don’t lose energy.

We test the exhaust gases of any fuel-burning appliances to detect potentially dangerous levels of gases and ensure optimal fuel efficiency.

Low air volume is more energy efficient and provides a more pleasant building environment, but can be harder to measure. We use state-of-the-art measuring devices to accurately track low-volume flow.

Whether you need a few pipes moving or a heating system installed – our team can do it, no problem. 

We can provide mechanical services as part of our installations, including but not limited to;

  • Low Pressure Hot Water (LPHW)
  • Chilled Water
  • 2 & 4 Pipe Systems
  • Chilled Beams
  • VRF/VRV/DX AC systems
