Planning document information


A noise assessment, is a report that determines the current level of noise at the proposed development. The assessment also predicts the level of impact that the new proposal will have on this existing noise level. 


The report you submit should include an executive summary and be clear, easy to read and jargon free. 

If you need to submit a noise impact assessment but cannot carry it out at the site proposed development site, you should carry it out at a similar site. 

If the only part of your application that needs a noise impact information is an extraction system or condenser unit you may not have to submit a full report. If the manufacturers details of these units include either the 'sound power level' or the 'sound pressure level' this will provide enough information. 

You can also talk to our Environmental Health team for more help and advice. 

You should also read about the requirements for submitting a Fume, extraction and ventilation assessment. 

You can get help and advice from our Duty Planner on noise impact assessments and planning applications.
