We proudly hold corporate membership with the Institute of Acoustics (IOA) – the UK’s leading professional body for acousticians. This accreditation demonstrates our technical competence and commitment to maintaining the highest industry standards, giving clients full confidence that every assessment is carried out in line with best practice and national guidance.
Our services cover locations including Cardiff, Swansea, Newport, Wrexham, Bangor, and Llanelli, as well as wider regions across Wales.
We undertake all types of environmental noise surveys and acoustic assessments, including:
Planning application support and discharging conditions
BS 4142, BS 8233 & BS 5228 assessments
Environmental permitting and workplace noise risk assessments
Post-occupancy noise nuisance investigations
Planning authorities often request environmental noise assessments to make sure new residential, commercial, or mixed-use developments meet national standards. Without the right evidence, applications risk delays, refusals, or objections from Environmental Health Officers.
BS 8233 – Assesses noise levels inside and outside dwellings, ensuring acceptable living conditions. Reports translate data from traffic, railways, or commercial activity into design advice such as glazing, façade layout, and ventilation strategies.
BS 4142 – Focuses on assessing the potential impact of industrial and commercial sound (e.g., plant, machinery, or extraction systems) on nearby residential areas. It helps determine whether noise is likely to be a source of complaint.
BS 5228 – Provides guidance on controlling noise and vibration from construction sites, making it essential for developers managing demolition, piling, or major building works.
By commissioning these assessments early, you strengthen your planning application, reduce risks, and keep your project on track.

If you’re planning a residential, commercial, or mixed-use development in Wales, you may need to demonstrate compliance with standards such as BS 8233, BS 4142, or BS 5228, as well as Welsh Government guidance including TAN11: Noise.
Understandably, many developers, architects, and planning consultants have questions about what an environmental noise survey involves and how it supports a planning application in Wales.
From how surveys are carried out on site, to the information included in a professional acoustic report, this section answers some of the most common queries we receive.
Each response is designed to give you practical insight into the process, timelines, and requirements, helping you make informed decisions, satisfy Welsh planning authorities, and keep your project progressing without delays.
In Wales, a noise assessment is often required whenever a proposed development is likely to be affected by noise or generate noise that impacts surrounding communities. For example, residential developments close to busy roads, railways, or industrial areas will typically need a BS 8233 assessment to demonstrate acceptable internal and external noise levels.
Similarly, new commercial or industrial schemes introducing plant, equipment, or machinery may require a BS 4142 assessment. The Welsh Government’s Technical Advice Note (TAN) 11: Noise provides guidance to planning authorities on how noise should be considered during the planning process. Many councils, including Cardiff, Swansea, and Newport, will not validate or approve applications without robust acoustic evidence.
A noise assessment demonstrates that a scheme meets both national guidance and local planning policies, reducing objections and ensuring planning consent can be granted without unnecessary delay.
A BS 8233 noise survey assesses the impact of environmental noise on new or refurbished residential properties, ensuring that acceptable indoor and outdoor noise levels can be achieved.
In Wales, this type of assessment is particularly important for developments near major transport routes such as the M4, Cardiff Central rail corridor, or industrial estates in South Wales. The process typically involves placing calibrated sound level meters on-site to record noise over representative periods, including daytime and night-time. The data is then compared against BS 8233:2014 criteria for internal and external noise. Where predicted levels exceed recommended limits, the acoustic consultant will propose mitigation such as upgraded glazing, acoustic trickle vents, or barriers.
Reports are tailored to Welsh planning policy, including TAN11, to demonstrate compliance. By commissioning a BS 8233 survey early, developers can avoid costly redesigns, reassure local planning authorities, and ensure future residents benefit from good acoustic comfort.
BS 4142 assessments evaluate the noise impact of industrial and commercial sound sources, such as mechanical plant, HVAC equipment, or generators, on nearby sensitive receptors.
In Wales, planning authorities often require BS 4142 reports when considering applications for new commercial developments or building services installations in mixed-use areas. The method involves measuring or predicting the specific noise level of the source, applying any acoustic corrections (e.g. for tonality or impulsiveness), and comparing it to the existing background noise. The difference between the two values indicates the likelihood of adverse impact. Planning authorities in Cardiff, Swansea, and Wrexham frequently rely on BS 4142 results when imposing conditions or approving schemes.
A clear report, aligned with both the standard and TAN11, reassures decision-makers that noise risks have been properly assessed and mitigated. This avoids planning refusals, ensures compliance, and provides developers with confidence that operational noise will not cause complaints.
BS 5228 provides guidance on predicting and controlling noise and vibration from construction and demolition sites. In Wales, local authorities frequently reference BS 5228 when setting planning conditions or granting Section 61 prior consents.
For major projects such as infrastructure works, city-centre redevelopments, or large housing schemes, construction noise can become a significant issue for nearby residents and businesses. A BS 5228 assessment predicts likely noise and vibration levels from equipment such as piling rigs, breakers, and excavators, then compares results to recognised thresholds. Where risks are identified, the consultant recommends practical control measures such as restricted working hours, acoustic hoarding, or monitoring programmes. Compliance monitoring throughout the works can also be required.
By undertaking a BS 5228 assessment, contractors demonstrate proactive management of noise and vibration, reducing the risk of complaints, enforcement action, or costly project delays. It also reassures planning authorities and the public that construction impacts will be responsibly controlled.
Technical Advice Note (TAN) 11: Noise is a key planning document in Wales, setting out how local authorities should consider noise when making land-use decisions. It complements British Standards by giving councils a framework for determining whether noise-sensitive development (such as housing or schools) is appropriate in a given location, and whether noisy uses (such as industrial sites or entertainment venues) are suitably located. TAN11 highlights the importance of balancing economic growth with environmental protection, ensuring communities are not exposed to unacceptable noise levels.
For developers and architects, this means that planning applications must be supported by robust acoustic evidence, clearly demonstrating how noise impacts have been assessed and mitigated.
Failure to address TAN11 considerations often results in planning delays or refusals. By referencing TAN11 directly in acoustic reports, consultants like Polaris Acoustics provide planning officers with the assurance that both local and national policy requirements have been fully addressed.
Project timelines are often tight, and delays in securing planning consent can have costly knock-on effects. At Polaris Acoustics, we understand these pressures and offer fast, reliable turnaround times across Wales.
Standard environmental noise surveys can usually be completed within 3–5 working days of instruction, with final reports delivered shortly after data analysis. For urgent projects, we also offer express services, where surveys and draft reports can be produced within 24–48 hours, subject to site access and conditions. More complex assessments, such as BS 5228 construction noise monitoring or BS 4142 industrial plant assessments, may take longer due to the need for extended measurements or stakeholder consultation.
Regardless of complexity, our reports are always tailored to Welsh planning policy, including TAN11, and written with decision-makers in mind. This approach ensures that applications proceed smoothly, with reports that are both technically robust and accessible to planners.
