What Is a Noise Impact Assessment?

A noise impact assessment is a technical report that measures the noise environment at a development site and evaluates whether noise levels are acceptable for the proposed use. It is carried out in accordance with BS 4142, BS 8233, and PPG24. Where noise levels exceed acceptable thresholds, the report recommends mitigation measures such as acoustic glazing, mechanical ventilation, or barrier walls.

Planning authorities require them because they have a legal obligation to protect future residents and existing communities from unacceptable noise. If your site is near a road, railway, industrial premises, or any other significant noise source, your local planning authority will almost certainly require an assessment before granting permission.

Our noise impact assessments are produced by engineers using UKAS-traceable monitoring equipment and are written to the standards that planning officers expect. Our reports are accepted by planning authorities on first submission in 98 percent of cases.

Who Needs a Noise Impact Assessment?

A noise impact assessment is required in a wide range of planning scenarios:

Residential development near a busy road, motorway, or railway

Commercial or industrial premises near existing residential properties

Change of use applications where noise-sensitive uses are being introduced

Applications where the planning authority has attached a noise condition

Applications that have previously been refused on noise grounds

Mixed-use developments with residential above commercial units

When Is a Noise Impact Assessment Required?

A noise impact assessment is normally required at the planning application stage. If your site has significant noise sources nearby, submitting a noise assessment with your initial application reduces the risk of a noise condition being attached or your application being refused.

Where a planning condition has already been attached, the assessment is required to discharge that condition before building works can begin. Where an application has been refused on noise grounds, a fresh assessment addressing the planning authority’s specific concerns is required for resubmission.

How Does the Noise Assessment Process Work?

  1. 1
    Initial Consultation

    We discuss your site, your planning situation, and what the local planning authority has asked for. By the end of the call you will have a fixed price and a clear timeline. No obligation.

  2. 2
    Site Monitoring

    One of our engineers visits the site with calibrated, UKAS-traceable noise monitoring equipment. We measure ambient and specific noise levels at the times and locations relevant to your application.

  3. 3
    Data Analysis

    We process the measurements against the applicable standards — BS 4142, BS 8233, PPG24 — and assess whether noise levels at your site are within acceptable limits for the proposed use.

  4. 4
    Report Production

    We produce a full technical report setting out the methodology, measurements, analysis, and conclusions. Where noise levels require mitigation, we specify the measures required and demonstrate compliance.

  5. 5
    Submission

    Your completed noise impact assessment arrives within five working days, formatted and referenced for direct submission to your local planning authority.

How Does the Air Tightness Test Process Work?

How much does a noise impact assessment cost? +

It depends on the site, the noise sources, and what the planning authority has asked for. We give you a fixed price after a free phone call. No surprises, no hourly rates, no extras.

How long does it take from start to finish? +

For working days in our standard turnaround from survey to final report. If you need it faster, ask us. We can often accommodate urgent requests.

Will the council accept your report? +

Yes. Every report we produce is written to BS 4142, ProPG, and BS 8233 standards. It includes all the data, methodology, and conclusions that planning officers expect. Our first-time acceptance rate is 98 percent.

Should I get the assessment done before or after I submit my planning application? +

Before, in most cases. If your site is near a busy road, a railway, or commercial or industrial premises, the planning authority will almost certainly ask for one. Getting it done upfront avoids delays and shows the council you are serious.

My planning application has already been refused on noise grounds. Can you help? +

Yes. We regularly help clients whose applications have been refused or conditioned. We review the planning officer’s comments, carry out the survey, and write a report that addresses every concern they raised. We also have a strong track record of getting refusals overturned on resubmission.

Do you cover Luton Borough Council specifically? +

Yes. We work with Luton Borough Council, Central Bedfordshire, North Hertfordshire, Dacorum, St Albans City and District, and every other LPA within our 50-mile service area. We know what each authority expects and we write to that standard.
