Overview

About the service.

Indoor air quality has a direct impact on the health, comfort and wellbeing of building occupants. Poor ventilation, airborne particles, elevated CO₂ levels and other environmental factors can contribute to reduced air quality, affecting both occupant comfort and workplace performance.

Our engineers carry out professional indoor air quality (IAQ) testing to assess key environmental conditions, identify potential air quality concerns and provide accurate data to support informed maintenance, ventilation improvements and healthier indoor environments.

What’s included

  • CO₂ concentration testing
  • Particulate matter (PM) monitoring
  • Temperature & humidity measurements
  • Indoor air quality reporting
  • Recommendations & remedial advice

IAQ Insights

Understanding your environment.

Every indoor air quality assessment provides clear, objective data on the conditions within your building, helping you understand how effectively your ventilation system is supporting occupants. Our reports present accurate measurements in an easy-to-understand format, allowing you to identify potential air quality concerns before they become more significant.

Where improvements are identified, we provide practical recommendations to help enhance ventilation performance, improve indoor air quality and create healthier, more comfortable environments for building occupants.

Why it matters

Creating healthier indoor environments.

Routine indoor air quality testing helps identify air quality issues, support occupant wellbeing and provide the information needed to improve building ventilation.

Healthier environments

Assess key air quality indicators that can affect occupant health, comfort, wellbeing and the overall indoor environment.

Better ventilation

Identify ventilation deficiencies that may contribute to poor air quality, stale air and elevated CO₂ levels.

Informed decisions

Objective test data supports maintenance planning, ventilation improvements and targeted remedial works.

Ongoing assurance

Regular assessments provide a documented record of indoor air quality, helping monitor building performance over time.

How it works

From testing to report.

A clear, accountable process — supported by accurate measurements.

01

Assess

We discuss any air quality concerns, review the building’s ventilation and identify the areas or spaces requiring assessment.

02

Measure

Using calibrated instruments, we measure key indoor air quality parameters including CO₂, particulate matter, temperature and humidity.

03

Evaluate

The results are assessed to identify potential air quality issues, ventilation deficiencies and environmental conditions that may affect occupant comfort.

04

Report

You receive a comprehensive report detailing the test results, observations and practical recommendations to help improve indoor air quality where required.

Sectors we serve.

We clean and certify ventilation systems across a wide range of commercial and industrial settings.

FAQs

Common questions.

What is indoor air quality (IAQ) testing?

Indoor air quality testing measures key environmental conditions within a building to assess air quality, identify potential issues and help create healthier, more comfortable indoor environments.

What does IAQ testing measure?

Depending on your requirements, we can measure factors such as carbon dioxide (CO₂), particulate matter, temperature and humidity to assess the overall quality of the indoor environment.

When should indoor air quality be tested?

IAQ testing is recommended where occupants experience poor air quality, discomfort or ventilation concerns, following building alterations, or as part of a proactive building maintenance strategy.

What do I receive after the assessment?

Every assessment includes a detailed report containing the test results, observations and practical recommendations, providing a clear record of your building’s indoor air quality.
