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 (see our guide to odour management and compliance in the UK). As a result, you may also avoid potential fines and legal consequences.

- What causes odour complaints
- How to understand, handle and prevent complaints

Understanding Odour Complaints
Before you can manage complaints effectively, it is important to understand where they come from and why they occur.
Common Sources of Odour Complaints
Many industries emit odours as part of their normal operations (see: common odour sources). 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
Estimates suggest that a single odour complaint can generate over 250 negative community touchpoints.
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 Responsibility
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 Managing Odour Complaints
The process below outlines how complaints should be handled. It covers initial contact through to resolution and record keeping.
| Step | Action | What This Involves |
|---|---|---|
| 1 | Acknowledge Complaint | Recognise the complaint, gather details (time, location, odour description) and reassure the complainant that it will be investigated. |
| 2 | Investigate Source | Carry out odour sampling and surveys to identify the source and confirm whether controls are working as expected. Speak to an experienced odour consultant to ensure your investigation is effective. |
| 3 | Communicate Findings | Share findings with the complainant and explain next steps, including timescales for resolution. By demonstrating transparency and accountability, you can build trust and positivity. |
| 4 | Take Corrective Action | Adjust processes, improve controls or update equipment as needed. Document all changes within your odour management plan. |
| 5 | Close Complaint | Confirm resolution with the complainant, request feedback and record outcomes for compliance purposes. |
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. 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 type of enforcement typically follows investigations where statutory nuisance is established.
The case highlights the importance of having a strong odour management strategy and the right tools to address and prevent complaints.
The Wider Impact of Odour Complaints
Evidently, odour complaints are an operational issue. But they also have broader psychological, social and economic consequences for both communities and operators.
