Section 61

What is Section 61?

Section 61 of the Control of Pollution Act 1974 (England and Wales) is a critical tool used by local authorities to regulate and control activities that may cause significant environmental pollution or nuisance. In the realm of construction, demolition,and civil engineering projects, adhering to environmental regulations is crucial for ensuring legal compliance and minimising the impact on local communities and ecosystems. Section 61 plays a vital role in managing noise pollution construction sites. Understanding the intricacies of a Section 61 application and its implications can significantly benefit project managers, environmental consultants, and contractors. This article explores the purpose of Section 61 applications, how they are applied, and their importance in environmental management.

Purpose of Section 61

The primary purpose of a Section 61 is to empower local authorities to address potential sources of pollution or nuisance from industrial, commercial, or other operations. It allows authorities to impose conditions or prohibit activities that could harm the environment or affect the well-being of nearby communities and enables contractors to open a dialog with the local authority regarding their works and methodology to ensure the job can be done, is compliant and no one is adversely impacted.

Application Process

Businesses or individuals engaged in activities that may impact the environment, such as emitting noise, odours, dust, or other pollutants, may need to apply for a Section 61 consent from their local authority, especially if works are large, impactful, in Central London or near sensitive receptors. The application typically requires detailed information about the nature of the activity, its potential environmental impacts, and proposed measures to mitigate these impacts. The application will got through a number of steps starting with Assessment and Planning. This step includes a thorough assessment of the potential noise impact caused by the project that will be carried out, identifying noise sources, predicting noise levels, and evaluating the proximity of sensitive receptors such as residential areas, schools, and hospitals.


Based on the assessment, contractors must develop a plan for noise control, which is the second step. Contractors must show that they are implementing Best Practicable Mean (BPM). This may include using quieter equipment, implementing noise barriers, scheduling noisy activities during less disruptive times, and providing communication channels for residents to report concerns. Then the application is submitted to the local authority. It is essential to provide detailed and accurate information to facilitate a smooth review process.

The local authority reviews the application and may come back with comments and request modifications or additional measures. Once the local authority is satisfied, they will grant a Section 61 consent, specifying the terms of the application including the agreed noise control measures and monitoring requirements.

Once a Section 61 consent is obtained, continuous monitoring and compliance are crucial. Contractors must implement the agreed-upon noise control measures and maintain records of noise levels. Regular communication with the local authority ensures ongoing compliance and addresses any emerging issues promptly.

The Role of Environmental Consultants

Environmental consultants play a pivotal role in the Section 61 process. Their expertise in noise assessment, modelling, and mitigation is invaluable for preparing comprehensive applications and ensuring effective noise control. Consultants like EEMC specialise in creating detailed noise models, which are a requirement for all large construction/demolition projects within Central London, using advanced software like CadnaA, providing accurate predictions and actionable insights.

Importance in Environmental Management

Section 61 applications play a crucial role in ensuring compliance with environmental regulations and protecting public health and well-being. By obtaining a Section 61 consent, businesses demonstrate their commitment to responsible environmental stewardship and minimise the risk of legal penalties or enforcement actions from regulatory authorities.

Environmental Impact Assessment: Applicants must assess and document the potential environmental impacts of their activities, including measures to mitigate adverse effects.
Community Consultation: Depending on the nature of the activity, applicants may need to engage with local communities to address concerns and gather feedback.
Compliance Monitoring: Once a consent is granted, ongoing monitoring and reporting may be required to ensure continued compliance with the conditions set out in the Section 61 consent. Section 61 of the Control of Pollution Act 1974 provides a vital mechanism for managing environmental impacts associated with industrial and commercial activities.

By requiring businesses to apply for consent before conducting potentially polluting operations, Section 61 helps safeguard environmental quality and protect communities from harm. Section 61 requirements are essential steps for businesses committed to sustainable development and regulatory compliance in the UK.

Understanding and adhering to Section 61 is not just about regulatory compliance; it reflects a commitment to responsible construction practices that benefit both the project and the broader community.
