It's also not the case that if the homeowner is a SW recipient that they will automatically get a waiver if available in their area. If your household income comes from the DSFA or if your household income is not liable for income tax you can get bin tags free of charge. The local authority requires proof of all household income, so, basically if someone living in the house is working & paying tax, or if the homeowner has an additional pension etc, the chances are they would not qualify for a waiver, but as local authorities differ, as Darthvadar advised, they should check to make sure.
