BS 4142 is a British Standard that provides guidelines and criteria for assessing the potential impact of noise from industrial and commercial sources on nearby residential areas. Titled “Methods for Rating and Assessing Industrial and Commercial Sound,” this standard outlines procedures and criteria for evaluating noise emissions from various sources and their potential effects on the surrounding environment, particularly residential properties.


BS4142: Methods for Rating and Assessing Industrial and Commerical Sound

BS 4142, a British Standard, serves as a comprehensive framework for evaluating and rating the impact of industrial and commercial sound on the surrounding environment. This standard not only provides methods for assessing noise but also outlines procedures for gauging its potential effects on nearby residential and sensitive areas.

The standard’s approach encompasses various facets, including the characterization of noise sources, duration of sound emissions, and the nature of the receiving environment. Factors such as background noise levels, existing noise sources, and potential disturbances to individuals are carefully considered.

The assessment process under BS 4142 involves several key steps:

  1. Data Collection: Gathering detailed information about the noise source, including its operational characteristics, proximity to sensitive areas, and local background noise levels.
  2. Noise Measurements: Conducting on-site measurements to quantify the noise generated by the source. This entails using sound level meters to capture noise levels at different distances and times.
  3. Background Noise Assessment: Evaluating the existing background noise levels in the surrounding environment to understand the baseline conditions.
  4. Noise Rating: Calculating the Noise Rating Level based on the activity’s sound level, considering additional penalties for specific acoustic characteristics.
  5. Impact Assessment: Comparing the calculated Rating Level with background noise levels to gauge potential adverse effects on sensitive receptors.
  6. Judgment: Based on the assessment, determining compliance with local authority requirements. If noise levels exceed acceptable limits, mitigation measures or operational adjustments may be necessary.

It’s crucial to recognise that while BS 4142 provides a standardized framework, its application may require professional judgment and expertise in acoustics and noise management. Local regulations and practices may influence the assessment process, underscoring the need for tailored approaches to ensure the well-being of the surrounding community is safeguarded.


Service Plant Noise Assessment

BS 4142 sets out the process for conducting noise assessments, including measurements and calculations, and it establishes specific noise level limits that should not be exceeded to prevent adverse impacts on the well-being of residents in the vicinity of industrial or commercial activities. It is a valuable tool for environmental consultants, local authorities, and businesses to ensure that noise emissions are managed in a way that minimises disruption and potential harm to the community.

What is required to be able to quote for a BS4142 Assessment?
  • Site Location Plans
  • Floor Plans and Section Drawings
  • Site Address and Contact
  • Planning Decision Notice
  • Proposed and/ or existing services (plant) including any relevant technical datasheets 
  • Any relevant correspondence with the Local Planning Authority and/ or Environmental Health Departments
How much does a BS4142 Assessment cost?

This will depend on the required scope of works, however our prices start from £950+VAT

How long does a BS4142 Assessment take?

A minimum of a continuous 24-hour monitoring of background noise and/or service plant noise is required in most instances. This typically is done by remote unattended monitoring. We would require safe and secure to the site to install and retrieve the noise monitoring equipment. In some instances further attended measurements might be required.

Once the on-site assessment is complete the report can take between 5-10 working days. We will always keep you updated.
