Indoor Air Quality Monitoring in Portsmouth

Portsmouth is one of the UK's most densely populated island cities, and its geography only compounds its air quality problem. Traffic is funnelled through a limited number of arterial routes on Portsea Island, while Portsmouth International Port generates a constant flow of HGVs, coaches, and ferries that define the city's waterfront. The problem is significant enough that Portsmouth was identified by the UK government for exceeding legal pollution limits — leading to the introduction of a Clean Air Zone in 2021. Despite this, some locations in the city continue to exceed the legal limit for nitrogen dioxide, with many more persistently close to the threshold.


That means pollution in Portsmouth isn't a periodic event — it's a background constant. It infiltrates offices, schools, retail units, and commercial premises throughout the city, mixing with indoor-generated contaminants like VOCs, CO₂ build-up, and particulate matter to create air quality conditions that shift throughout the day, week, and season.

We test for...

  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Volatile Organic Compounds (VOCs)
  • Formaldehyde (HCHO)
  • PM2.5 & PM10
  • Nitrogen Dioxide (NO2)
  • Sulphur Dioxide (SO2)
  • Mould and Microbial Life

What's involved in Indoor Air Quality Monitoring?

Unlike a one-off test, our indoor air quality monitoring service gives you a continuous, real-time picture of what's happening inside your building — so you can act on trends, not just snapshots.

We use advanced sensors to track pollutants concentrations and environmental conditions over time, detecting fluctuations and emerging trends as they happen. Once you book with us, the process flows in three simple steps:

  1. Initial Consultation: We discuss your building specifications, current air quality concerns, and whether short-term or permanent monitoring best suits your goals.
  2. Sensor Deployment: We install calibrated IAQ sensors across your building, connecting them via Wi-Fi, BACnet, or Ethernet to stream live data to a desktop or smartphone dashboard.
  3. Reporting & Recommendations: We deliver a thorough analysis of your monitoring data — identifying patterns, problem areas, and practical improvements — with expert recommendations you can act on.

What are the Benefits of Indoor Air Quality Monitoring?

Understanding how your indoor air quality changes over time gives you far greater power to protect the people inside your building and remain compliant with UK legislation and guidelines. With continuous monitoring you benefit from:

  • Compliance: demonstrate ongoing adherence to UK regulatory standards with time-stamped, real-world data and reports

  • Health: detect and address pollutant spikes before they cause headaches, fatigue, or staff absences
  • Productivity: maintain the low-pollutant conditions that support cognitive performance and focus

  • Energy Savings: identify over-ventilation and HVAC inefficiencies that are costing you money

  •  
  •  

Did you know?

Air inside a building can be up to 5x more polluted than the air outside.
 
With continuous monitoring data, you can match pollutant spikes to real-world events, like heavy traffic, ventilation schedules, and high building occupancy times.
