Introduction
A construction noise assessment is often required for UK planning applications where construction activities could affect nearby residents or sensitive land uses. Local planning authorities use construction noise assessments to understand how noise will be managed during the construction phase of a development.
This blog explains what a construction noise assessment involves, how BS 5228 is applied, and how the assessment supports planning approval.
What Is a Construction Noise Assessment?
A construction noise assessment evaluates the potential noise impacts associated with construction activities. Unlike operational noise assessments, it focuses specifically on temporary noise generated during site works.
A construction noise assessment typically:
- Considers proposed construction activities
- Assesses likely noise impacts on nearby receptors
- Reviews appropriate standards and guidance
- Identifies suitable mitigation measures
The assessment is planning-led and proportionate to the scale of development.
When Is a Construction Noise Assessment Required?
Local authorities may request a construction noise assessment where development:
- Is close to residential properties
- Involves prolonged or intensive construction works
- Includes demolition, piling, or earthworks
- Is located in noise-sensitive areas
The requirement is usually identified during planning or at pre-application stage.
Understanding BS 5228
BS 5228 provides guidance on:
- Noise and vibration control on construction sites
- Typical noise levels for construction activities
- Best practice mitigation measures
A construction noise assessment often references BS 5228 to demonstrate that potential impacts have been properly considered.
What Does a Construction Noise Assessment Cover?
Site Context and Receptors
The assessment identifies:
- Nearby residential and sensitive receptors
- Site layout and access routes
- Construction phases relevant to noise
This ensures impacts are assessed accurately.
Assessment Methodology
A clear construction noise assessment explains:
- The approach used to estimate noise levels
- Relevant assumptions
- How BS 5228 guidance has been applied
Transparency is key for planning review.
Mitigation Measures
Mitigation may include:
- Programming of noisy activities
- Use of quieter plant where practicable
- Site management measures
Planners expect mitigation to be realistic and enforceable.
How a Construction Noise Assessment Supports Planning
A well-prepared construction noise assessment helps to:
- Address environmental health concerns
- Support planning conditions
- Reduce objections from nearby residents
It demonstrates that construction impacts have been responsibly managed.
Conclusion
A construction noise assessment plays an important role in planning applications where construction activity could affect neighbours. By applying BS 5228 guidance and proposing proportionate mitigation, the assessment helps ensure development is acceptable during construction.
Early assessment can help prevent delays later in the planning process.
Frequently Asked Questions
Q1: Is a construction noise assessment required for all developments?
A1: No. It is typically required only where construction noise could materially affect nearby receptors.
Q2: Does BS 5228 set mandatory limits?
A2: No. BS 5228 provides guidance that informs assessment and mitigation.
Q3: Who reviews construction noise assessments?
A3: Planning officers and environmental health teams usually review them.
