Bad Smells: A Statutory Nuisance?

Understanding Statutory Nuisances and Offensive Odours in the UK

The presence of unpleasant and persistent smells can significantly impact the quality of life for residents. In the United Kingdom, legislation exists to address certain types of nuisances, and a key question many people have is whether bad smells can fall under the umbrella of a 'statutory nuisance'. This article delves into the legal framework surrounding offensive odours, focusing on what constitutes a statutory nuisance and how local authorities handle such complaints.

What is a Statutory Nuisance?

The Environmental Protection Act 1990 is the primary piece of legislation that governs statutory nuisances. This Act provides local councils with the power to act when a nuisance is deemed to be prejudicial to health or is an "unreasonable" interference with the enjoyment of a property. While the Act covers various forms of nuisance, including noise and dust, it also addresses offensive smells emanating from specific sources.

When Do Bad Smells Qualify as a Statutory Nuisance?

Crucially, statutory nuisance laws in the UK primarily apply to smells originating from commercial, industrial, or trade premises. This means that if a bad smell is causing a significant problem, and it can be traced back to a business or industrial activity, it is likely to be considered a statutory nuisance. The law mandates that local councils must serve an abatement notice when such nuisances are occurring, have occurred, or are likely to occur. An abatement notice is a legal requirement for the responsible party to take action to stop or restrict the offensive odour.

Important Distinction: It is vital to understand that statutory nuisance laws generally do not apply to bad smells originating from residential properties. For instance, persistent unpleasant odours from a neighbour's home are typically not covered by this specific legislation, and different avenues may need to be explored for resolution.

Common Sources of Nuisance Smells

Offensive odours that can qualify as statutory nuisances are often linked to specific types of operations. These commonly include:

• Abattoirs and Rendering Plants: Facilities involved in animal slaughter and the processing of animal by-products are frequent sources of strong, unpleasant smells.
• Agricultural and Farming Practices: Activities such as livestock farming, poultry operations, and the spreading of slurry or manure on land can release significant odours.
• Food Processing and Commercial Kitchens: Businesses involved in food preparation and processing, especially those with inadequate extraction systems, can generate offensive smells.
• Sewage Handling Facilities: This category includes sewage treatment works, pumping stations, sludge treatment centres, and storm water storage tanks, all of which can produce foul odours.
• Chemical and Solvent Emissions: Industries using paints, hazardous solvents, or other chemicals, such as car sprayers or vehicle workshops with poorly positioned air vents, can also be a source of nuisance smells.
• Road Traffic Incidents: While less common, unplanned spills on highways resulting from accidents can sometimes lead to localised offensive odours.

How Smells Escape Premises

Unwelcome or hazardous smells typically escape from commercial and industrial buildings through several routes:

• Ventilation Systems: Emissions released from extractor fans or chimney stacks are a primary pathway for odours to spread into the surrounding environment.
• Building Structure: Leaks from the actual building structure, such as through poorly sealed doors or windows, can also allow odours to escape.

How Local Councils Assess Nuisance Smells

When a complaint about a bad smell is made, local councils employ a systematic approach to assess the situation and determine if it constitutes a statutory nuisance. The process typically involves:

1. Determining if it's a Statutory Nuisance

The council will first investigate the source of the smell to ascertain if it originates from a commercial, industrial, or trade premise. They will consider:

• The Character of the Area: The general nature of the locality is taken into account. A smell that might be considered a nuisance in a quiet residential area might be viewed differently in an industrial zone.
• The Number of People Affected: The extent to which the smell impacts the local population is a key factor.

2. Characterising the Odour

Assessing smells for legal purposes is not always straightforward, as individual perceptions can vary. Councils often use a combination of methods, including:

• Human Assessment ('Sniffers'): It is common for councils to employ two or more trained individuals to assess the smell. These individuals attempt to detect and describe the smell's:
• Strength: How potent is the odour?
• Frequency: How often can the smell be detected?
• Duration: How long does the smell linger in the air?
• Character: Describing the nature of the smell (e.g., 'fishy', 'chemical', 'sweet', 'putrid').
• Offensiveness: Whether the smell is considered unpleasant or offensive.
• Emission Rate: The volume or speed at which the odour is being released.
• Smell Diaries: To gather more consistent data and understand the impact on residents, councils may ask complainants to keep a detailed smell diary. This diary should record:
• The date and time the smell was detected.
• The perceived strength and character of the smell.
• The duration of the smell.
• How the smell affected daily activities (e.g., preventing outdoor use of gardens, causing sleep disturbance).

Factors Influencing Assessment: It's important to note that weather conditions, such as wind direction and speed, can significantly influence how and where a smell travels. While these variations exist, they do not negate the potential for a nuisance if the smell is persistent and offensive.

Abatement Notices and Legal Defences

If a council concludes that a statutory nuisance exists, they have the authority to serve an abatement notice on the business or individual responsible. This notice will specify the actions required to abate (stop or reduce) the nuisance.

Appeals and Defences

Businesses that receive an abatement notice have certain rights:

• Appeal Against the Notice: They can appeal the notice if they believe it is unwarranted or incorrect.
• Use as a Defence: If prosecuted for failing to comply with an abatement notice, a business may use its actions as a defence, provided they can demonstrate that they took all practicable means to stop or reduce the offensive odour. This highlights the importance of proactive measures to control emissions.

Environmental Permits and Pollution Control

For certain industrial activities that are significant sources of pollution, including odour, the Environment Agency (EA) issues environmental permits. These permits set conditions and limits for emissions, helping to control hazardous smell nuisances.

The system is designed to prevent double penalties for the same activity. Therefore, if a business is operating under an environmental permit that already addresses odour control, the local council may need to consider this when assessing a statutory nuisance complaint. It is advisable for businesses to check if they require an environmental permit and to understand the application process through the Environment Agency.

What Can You Do?

If you are experiencing persistent and offensive smells from commercial or industrial premises, the first step is usually to contact your local council's environmental health department. Provide them with as much detail as possible, and consider keeping a smell diary as suggested.

Frequently Asked Questions

Q1: Can I complain about a bad smell from my neighbour's house?
Generally, statutory nuisance laws do not cover smells from private residential properties. You may need to explore alternative dispute resolution methods or community mediation.

Q2: What kind of smells are considered a statutory nuisance?
A smell is considered a statutory nuisance if it originates from commercial, industrial, or trade premises, is prejudicial to health, or is an unreasonable interference with the enjoyment of your property. Factors like strength, frequency, duration, and offensiveness are assessed.

Q3: What happens if a business doesn't comply with an abatement notice?
If a business fails to comply with an abatement notice, they can face prosecution, which may result in fines.

Q4: How do I keep a good smell diary?
Record the date, time, duration, strength, and type of smell. Also, note how it affected you and your activities. Be as objective and detailed as possible.

Q5: Do environmental permits cover all bad smells?
Environmental permits are issued by the Environment Agency for certain industrial activities with significant pollution potential, including odour. They are a key mechanism for control, but the local council still has powers under the Environmental Protection Act 1990 for statutory nuisances not adequately covered by permits or from sources not requiring them.
