This project focused on getting a clearer picture of the indoor air quality inside a small office space in Kennington, London, following concerns from staff about how the environment felt during the working day. The aim wasn’t to drown anyone in data, but to understand what might be contributing to discomfort and whether the indoor environment was supporting healthy, comfortable working conditions.
The assessment looked at how the space was used day to day, how air moved through the building, and whether there were any obvious indoor factors that could be affecting air quality. Particular attention was paid to areas where people spend the most time together, such as meeting rooms and shared spaces, as these are often where issues tend to show up first. The building itself had been recently refurbished, which can sometimes change how air behaves indoors, especially when ventilation relies heavily on opening doors and windows.
Overall, the indoor air quality across most areas of the office was found to be generally acceptable, but there were signs that some spaces were more prone to issues than others. In particular, rooms with limited airflow and higher occupancy appeared more vulnerable to stale air and biological build-up. This lined up with staff feedback, where symptoms were more noticeable during busier periods and eased when people were away from the office.
The findings highlighted how important consistent ventilation is, especially in smaller or enclosed workspaces. While nothing unusual was found in terms of everyday office-related pollutants, the assessment made it clear that relying solely on natural ventilation can be hit and miss, particularly in colder months when windows stay closed.
In short, this project reinforced a simple message: indoor air quality isn’t just about the building itself, but how it’s used. Small changes to ventilation and airflow can make a big difference to comfort, wellbeing, and how a space feels to work in.
Sysco Environmental recently completed a detailed Air Quality Monitoring Assessment for a creative prosthetics and model-making workshop located near Wembley. The project aimed to help the client understand their team’s exposure to airborne contaminants such as dust, resins, and vapours commonly generated during mould-making, pottery, and model fabrication tasks.
The goal was straightforward — to get a realistic picture of workplace air quality and ensure it met COSHH (Control of Substances Hazardous to Health) requirements. During the visit, Sysco’s occupational hygienists observed everyday production activities and measured air concentrations in key areas of the workshop. While all recorded levels of airborne substances were within Workplace Exposure Limits (WELs), several opportunities for improvement were identified to ensure long-term protection for staff and freelancers.
Sysco recommended introducing proper local exhaust ventilation (LEV) systems to capture contaminants at their source, replacing basic wall fans which currently only move air around. Improving respiratory protection practices — such as consistent use of FFP3 masks and proper face-fit testing — was also advised. Routine health surveillance and refresher training on dust suppression and solvent handling would further strengthen workplace safety culture.
This assessment underlined how creative workshops, though small-scale, can involve complex exposures due to diverse materials and production techniques. Through practical advice and periodic monitoring, Sysco Environmental continues to help clients maintain safe, compliant, and healthy working environments across the UK.
In October 2024, an Indoor Air Quality Assessment was carried out at a school in London after several staff members reported feeling unwell with symptoms like chest tightness, flu-like illnesses and headaches. The aim was to see if anything in the air such as dust, chemicals or poor ventilation could be contributing to how people were feeling.
The results were actually pretty reassuring for the school and its staff. Volatile organic compounds (VOCs), formaldehyde, carbon monoxide and dust levels were all well below guideline limits, meaning the air isn’t overloaded with any nasty substances. Carbon dioxide levels were slightly raised in a few rooms with high occupancy but even those were considered just marginal and not a serious concern.
Temperature and humidity levels were mostly within comfortable ranges, with just one or two spots—like the school kitchen—running a bit high on humidity.
The overall verdict was that the air quality is good and it’s unlikely that the symptoms reported were caused by chemical exposure or dust. A simple recommendation was made to open windows more often in busy rooms to boost airflow. With a few tweaks the school can keep the air clean and the staff feeling great.
In November 2024, an Indoor Air Quality Assessment was carried out at a multi-storey property in London following previous issues with water leaks and suspected mould. The aim was to check whether the air inside was safe and healthy following recent remedial works.
Air samples were taken throughout the property and compared with an outdoor background sample. The results were actually reassuring, showing that indoor mould spore levels were consistently lower than outdoors, showing that any remaining airborne mould presence was minimal. The most commonly detected spores indoors were Aspergillus/Penicillium, ascospores and basidiospores, which are typical in most environments and didn’t appear in high concentrations.
Surface sampling across multiple rooms also supported the findings that no active mould growth was identified, though there were light traces of environmental spores and dust, which are expected in everyday living spaces.
The overall conclusion was that the air quality indoors is in good shape, and the risk to health from fungal exposure is considered low. With continued good cleaning routines and ventilation, the property should remain a safe and healthy environment going forward. Nothing major needed, just keeping up the basics.
