Home Guides Best grounds to appeal General guidance, not legal advice
The grounds that actually work.Checked against the official sources linked on this page on 23 October 2026. Rules change, so check the dates on your own notice.

Pick the grounds that are true for you. A weak ground padded out with a sob story won’t beat a clear photo of a faded line.
“Strong”, “Worth arguing” and “Weak” are our reading of how firmly the official rule backs each ground. They’re a guide, not a prediction of any outcome.
Council PCNs
