Residential Planning Assessments

Planning policy guidance (PPG24) notes set out the Government policies on different aspects of planning. It is regularly used by Local authorities in order to place noise based planning conditions on potentially noisy residential sites. If required, property developers must have a PPG24 noise survey carried out in order to show that on-site noise levels are compliant with this document for the planning application to be accepted.

Mach Testing have great experience in carrying out PPG24 environmental noise assessments across all types of site, for any type of building. Our experience in this area allows us to undertake the most complex of environmental noise assessments with the minimal of fuss. Should a site be too noisy according to this document, Mach Testing have the expertise to provide noise mitigation measures such to comply with PPG24’s requirements.

PPG24 gives Noise Exposure Categories (NECs), ranging from A-D, to help local planning authorities in their consideration of applications for residential development near environmental noise sources. When assessing a proposal for residential development near a source of noise, local planning authorities will compare the measured on-site noise levels to these NEC’s in order to determine which of the four applies. If the noise levels fall into category A planning is normally granted. In bands B and C noise mitigation measured have to presented and accepted before the application can be granted. If noise levels are found to lie in category D, planning is normally refused.

Mach Testing have never had a planning application turned down due to noise levels falling into category D of PPG24. We have found that through clever planning and design even the noisiest sites can be shown to be suitable for property development.
