75 allowed and 126 dismissed (201 decided), plus 3 split decisions. That is 1.8 percentage points above the national average of 35.5%.

Only 13 Householder decisions in the last 12 months (we need 20 for a recent figure), so this covers all years.

Allowed ÷ (allowed + dismissed). Split decisions, withdrawn, invalid and undetermined appeals are left out. Based on completed records in the Appeal Scout archive, which runs a little behind today's date because decisions are added after publication.
