Why Precedents Are Powerful
“Planning officers must have regard to similar applications in the area. If a similar extension has been approved at a nearby property, it becomes harder to refuse yours without good reason.”
— National Planning Policy Framework, Paragraph 12
📍 Location Specific
Precedents on your exact street carry the most weight. Same conservation area is also relevant.
🏠 Property Type
Precedents on similar property types (Victorian terrace, Edwardian semi) strengthen your case.
📏 Scale & Design
Similar-sized extensions with similar materials provide the strongest support.
📅 Recent Decisions
Recent approvals (last 5 years) are most relevant as they reflect current planning policy.
