We work with contractors to assess the suitability of any proposed on-site works and to provide guidance and support to reduce noise and vibration at the neighbouring receptors.
Extraction System Noise Surveys & Assessments
What is an extraction system noise survey?
Extraction systems are among the most common noise nuisance complaints, especially in built-up areas where pubs and restaurants are located in close proximity to houses. The problems are exacerbated if commercial kitchen exhausts vent into small shared spaces or are located beneath residential units – flats and apartments situated above takeaways with late opening hours, for instance.
If catering businesses are located in busy city centres, extraction systems noise levels may well be indistinguishable from other ambient sounds – traffic and music systems – but in quieter areas, they could be more intrusive – and more likely to get a poor reception from neighbours. Acquiring accurate data on noise emissions is the only way to ensure your business complies with regulations designed to minimise noise nuisance. Assessing noise levels in context is crucial.
How are extraction system noise surveys used?
Challenges in Monitoring Construction Noise
An extraction system noise survey is usually a requirement when a planning application is being submitted to a local authority. The requirement is as likely to apply to smaller catering businesses, such as cafes and hot food shops, as it is to large commercial kitchens and takeaways, such as KFC and Nandos. A noise impact assessment to BS 4142:2014 will satisfy the local planning authority that proposals will not have an adverse impact on others.
Our thorough extractions system noise survey include:
- Background sound level assessment
- Assessment of noise emissions from the extractor fan (or acoustic modelling if the unit is not yet operational)
- Analysis of noise impact to BS4142:2014
- Recommendations for any noise mitigation measures (including fitting a silencer)
- Technical report for submission in support of a planning application
We approach every case with fresh eyes and you can be confident with our in-depth understanding and experience dealing with local authorities to achieve planning permission for a range of client for extraction systems.
Should the proposed installation seem likely to cause adverse impact, we will provide you with tailored advice regarding cost-effective and realistic solutions that will enable you to meet BS 4142:2014 standards, including changing or modifying the proposed unit, re-orientation or realignment, or the implementation of acoustic noise-reducing barriers or enclosures.

As urban areas continue to expand and human activities thrive, environmental noise pollution has become a significant concern.
Poor Sound Insulation is an issue that plagues many houses both small and large, through the development of noisy hobbies such as gaming systems, drum kits or food processors, or simply poorly soundproofed properties.
