PLANNING NOISE & VIBRATION ASSESSMENTS
We provide robust Noise Impact Assessments to support planning applications for residential, educational, commercial, industrial and mixed-use developments across the UK. Our assessments consider relevant noise and vibration sources and establish practical acoustic design and mitigation measures where required.
Working closely with architects, developers and planning consultants, we identify acoustic constraints early and provide proportionate advice to help secure planning approval. We can assist with noise related planning condition discharge, including liaison with the Local Planning Authority or Environmental Health where appropriate.

When might you need a Planning Noise Assessment?
Existing Noise Affecting a Site
Where existing road, rail, commercial or industrial noise could affect new noise sensitive development.
Noise from Proposed Site
Where a development could introduce new noise affecting nearby noise sensitive receptors.
Planning Condition Discharge
Where acoustic information is required to support planning application, condition or Environmental Health request.
Planning Noise Assessment Services
Environmental Noise Surveys
Measuring road, rail, commercial and industrial noise to establish site conditions and inform acoustic design.
Noise Impact Assessments
Assessing noise affecting or arising from a development to support planning applications and identify mitigation.
Residential Acoustic Design
Assessing façades, internal noise and external amenity using BS8233 and ProPG to support residential design.
Ventilation & Overheating
Reviewing noise implications of ventilation and overheating strategies, including reliance on open windows.
Commercial & Industrial Noise
Assessing commercial and industrial sound affecting or introduced by a development, including plant and equipment.
Vibration Assessment
Measuring and assessing vibration from railways, industry and other sources to inform development proposals.
Noise & Vibration Mitigation
Developing practical measures to control noise and vibration, tailored to the site layout and proposed scheme.
Planning Condition Discharge
Preparing technical submissions and liaising with planning and environmental health officers to address conditions.
Our Approach
We tailor each assessment to the development, surrounding noise sources and relevant planning requirements. Early consideration of acoustics helps inform the site layout and building design, addressing potential constraints before proposals become fixed.
Review the site, proposed uses, nearby noise sensitive properties and planning correspondence to establish the assessment requirements.
Undertake representative noise and vibration surveys where needed to establish existing conditions across relevant assessment periods.
Assess the effects of existing sources on the development and proposed sources on neighbouring noise sensitive properties.
Develop practical recommendations for site layout, façades, ventilation, external amenity areas and any necessary noise controls.
Prepare a clear report explaining the assessment findings, recommended measures and any further work that is required.
Advice is coordinated with the design team so that acoustic recommendations work alongside ventilation, overheating, construction and other requirements throughout the project.
Relevant Standards and Guidance
Assessments draw on the standards and guidance relevant to the site, surrounding sources and proposed development. Relevant references include:
BS 8233 — sound insulation and noise reduction in buildings.
ProPG — planning and noise guidance for new residential development.
BS 4142 — assessment of industrial and commercial sound.
BS 6472-1 — evaluation of human exposure to vibration in buildings.
BS ISO 1996-2 — environmental noise measurement and determination of sound pressure levels.
Local planning policy and Environmental Health requirements are also considered where applicable. We explain how the relevant criteria apply to the development and use the findings to inform practical recommendations for site layout, building design and noise control. Advice is coordinated with the wider design team to address acoustic requirements alongside ventilation, overheating and other project constraints.
Planning Conditions and Local Authority Liaison
We review planning conditions and Environmental Health comments to establish the acoustic information needed for a submission. Where appropriate, we liaise with the local authority to agree the survey scope, assessment method and relevant criteria before undertaking the work.
Our reports support planning applications and condition discharge, including details of recommended acoustic mitigation. We can respond to technical queries and, where further evidence is requested, advise on and undertake additional assessment or verification testing to address the outstanding requirements.
Frequently Asked Questions
Do I need a noise assessment for planning?
+
An assessment may be required where existing noise could affect a development, or new activities could affect nearby properties.
If the local authority has requested acoustic information, send us the wording with the site address and proposals so we can advise on the scope.
What is a BS 8233 assessment?
+
A BS 8233 assessment considers appropriate noise conditions within buildings and, where relevant, external amenity areas. For residential developments it can inform façade sound insulation and ventilation requirements, alongside the wider acoustic design and planning assessment.
Will I need an environmental noise survey?
+
A survey is often needed to establish representative site conditions. The requirement depends on the surrounding sources, the proposed development and any suitable existing data.
We will recommend survey locations and monitoring periods appropriate to the assessment.
Can you help discharge a noise planning condition?
+
Yes. We can review the condition, prepare the required assessment or mitigation details, and respond to acoustic queries. Where the condition requires checks after construction or installation, we can also undertake the relevant verification measurements.
