Do I require planning permission for a new septic tank or repairing an existing one?
Yes. Our advice is check with your local planning department but usually a new septic tank will require planning permission. Under normal circumstances, completely new septic tanks for new properties or developments will be included within the main planning approval for the new build project. The new septic tank will need to be installed in accordance with Building Regulations. If the new septic tank is replacing an existing system then Full Planning Permission may not be required, instead the work can be carried out under a Building Notice only, meeting the requirements of Building Regulations. It does not matter when your original tank was installed!
