Odour Complaints & How to Handle Them

Understanding, Managing & Preventing Odour Complaints
Odour complaints may seem minor, but they can have major consequences for compliance and community relations. Here’s how to handle them effectively.
Unpleasant odours can impact the health and well-being of those who live and work nearby. Facilities that emit odours often have specific odour conditions in their operating permits. Your permit may include acceptable odour emission levels and protocols for responding to odour complaints. It is important to know how to handle these complaints, so that you can maintain a safe and comfortable environment for everyone. Doing so will also help you to meet your statutory obligations. As a result, you may also avoid potential fines and legal consequences.
In this guide, we explore common sources of odour complaints and practical solutions to prevent and manage them. By following these tips, you will be better prepared to understand, handle and prevent complaints.
Understanding Odour Complaints
Common Sources of Odour Complaints
Many industries emit odours as part of their normal operations. The most common causes of complaints include;
- wastewater treatment plants
- food processing facilities
- waste management, landfills and composting sites
- agricultural operations
- chemical manufacturing plants
- commercial and restaurant kitchens.
Operators in these industries need to obtain proper permits and comply with environmental regulations. Councils must investigate odour complaints that could be a statutory nuisance.
Why Addressing Odour Complaints Matters
Did you know? For every odour complaint, there could be over 250 negative touchpoints affecting your community relations.
Even a single odour complaint should never be ignored. Failing to act can lead to:
- Impact on the health and quality of life of local residents
- Damaged community relationships and site reputation
- Breach of operating permits, leading to fines and legal action
- Subsequent impact on your time and financial resources

Challenges in Validating Complaints
Odours are subjective and can vary between individuals. It can be difficult to identify the source of an odour if there are a few different potential sources, or if it occurs sporadically or over a wide area. This means that sometimes, investigating an odour complaint can take a lot of time and resources. Even so, it is imperative to address complaints to avoid permit restrictions and legal consequences.
The first step is to conduct odour sampling and surveys. This type of investigation will help you to understand the nature of the emissions. At Silsoe Odours, our odour consultants will guide you on the best approach for your needs.
Handling Odour Complaints
Assigning Personnel
Having a consistent point of contact offers several advantages. For instance, they will know the details of previous complaints. This gives them a better understanding of possible issues, as well as effective methods to resolve them. A consistent liaison person also fosters trust within the local community. A recognisable face demonstrates accountability, prevents misunderstandings and helps build positive relationships. Furthermore, a centralised team is better equipped to maintain complaint-handling records. This is helpful if you need to show the regulator or a court your actions.
A Step-by-Step Approach to Odour Complaints
- Acknowledge
Begin by acknowledging the complainant’s concerns and assure them that you will investigate promptly. Gather information about the time, location and nature of the odour. This will help you to identify the potential problem. If the Environment Agency becomes involved, they will also follow similar steps.
- Investigate
Investigate the complaint promptly and thoroughly. Conduct odour sampling and surveys to determine the source and nature of your odour emissions. You can also use the results to confirm whether your odour abatement equipment is working as it should be. We recommend seeking support from an experienced odour consultancy to ensure your investigation is effective. You can contact Silsoe Odours for guidance.
- Communicate
Communicate the investigation’s findings to the complainant. Explain how you plan to resolve the issue and the expected timeframes. By demonstrating transparency and accountability, you can build trust and positivity. In some cases, you may also be required to do this as part of your permit stipulations.
- Take Corrective Action
Take action to fix the problem. For example, you might need to change some of your processes and operating practices. You could also install or update odour control equipment and ventilation systems. Put in place best practices to maintain and monitor changes. You should have an Odour Management Plan which outlines how you manage odours on your site. This will form part of your ongoing permit compliance actions.
- Close the Complaint
Lastly, take steps to close the complaint. Let the complainant know that the issue has been resolved. You may find it helpful to ask them for feedback on how you handled the issue. This can provide valuable insights for possible improvements. Update your records to show that you have resolved the complaint and archive related documentation. Remember, it is important to keep detailed records of all complaints.
Preventing Odour Complaints
Regular Monitoring & Maintenance
Prevention is always better than reaction. So, make sure your odour management practices are in great shape. Effective odour control systems and processes are important. But the most common mistake operators make is failing to track these systems once they are in place. Regular odour monitoring helps spot when things start to go wrong. This means that you can rectify them before they cause major problems. With this in mind, establish regular maintenance and cleaning procedures to ensure your odour control equipment is working. You should also develop an odour management plan that includes best practices for managing emissions. For example, regular sniff surveys and odour sampling can be valuable tools.
Community Engagement
We have outlined the importance of effective communication with complainants. You can also enhance your relationship with the wider community by creating an open dialogue. Publicise any changes to processes or systems that may affect odour emissions. When there are problems, provide updates on how you have solved them. Give details of the person or team responsible for odour complaints. You should also make sure that they are easy to contact. By being transparent and accessible, you may even receive informal reports of odour issues before they escalate into formal complaints.
Case Study: The Cost of Ignoring Odour
In 2023, a North East company was fined nearly £26,000 for failing to control odour and breaching its environmental permit. The company faced legal action from the Environment Agency after public complaints.
This case highlights the importance of having a strong odour management strategy and the right tools to address and prevent complaints.
