Indoor Air Quality

Professional Indoor Air Quality Testing and Monitoring in Bristol


During our testing, we identify the common contaminants present that affect whether the indoor air quality is acceptable or otherwise. We compare the results we get to the current occupational and workplace exposure limits and the relevant regulations. We then provide a list of recommendations when applicable and necessary.

The following parameters are measured in our standard suite of indoor air quality testing.

  • Airborne Bacterial Analysis
  • Airborne Fungal Analysis
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Relative Humidity (%)
  • Temperature (oC)

The number of contaminants found in indoor air should not exceed concentrations that have been found to cause discomfort or negatively impact the health of occupants. Examples of these contaminants are vapours, different gases, microorganisms, smoke, dust and other particulate matter.

The contaminants in indoor air may be introduced through building materials, furnishings, surface coatings, indoor activities, air treatment or air handling components. The factors considered include the following – toxicity, objectionable odours, potential to induce infections or allergies, irritants and thermal conditions. The contaminants can also already be present because of make-up air.

Apart from making sure that the indoor air in premises is safe for occupants, our indoor air quality assessments in Bristol also ensures compliance to regulations of the following.

  • The Chartered Institution of Building Services Engineers (CIBSE)
  • the Health & Safety Executive (HSE EH 40/02 Occupational Exposure Limits & HSE EH 40/05 Workplace Exposure Limits)
  • the Building Services Research and Information Association (BSRIA) and the Workplace (Health, Safety & Welfare) Regulations 1992.

The main objective of indoor air quality testing is to ensure the comfort parameters of the air and its overall hygienic quality.

We can also offer additional parameters to our suite including testing for Ozone (unstable Oxygen, O3), Nitrogen Oxide (NOx), Volatile Organic Compounds (VOC’s), and Total Dust Particulates.
