How do I know if my site requires a NNAMS and sHRA?

If your site falls within a designated nutrient neutrality catchment, it is very likely that a NNAMS and sHRA will be required as a condition of submitting a planning application. These requirements vary by LPA, so always check with your local planning authority early in the project. You can also contact WCI with your site’s postcode and we will confirm whether it falls within an affected catchment.
