Bulk Conservation Area Check

Need to check multiple postcodes at once? Bulk Check uses your API account. During the one-month free API trial, accounts can check up to 5 postcodes in a single request. Paid API plans support up to 500 postcodes per request.

How It Works

  1. Paste your postcodes — one per line, or comma-separated
  2. Or drag-and-drop a CSV — we'll extract the postcode column automatically
  3. Get instant results — each postcode checked against 9,300+ conservation area boundaries
  4. Download your report — CSV or JSON, ready for your workflow

What You Get

For every postcode in your batch, the result includes:

  • Whether the postcode is inside a Conservation Area (yes/no)
  • The name of the Conservation Area (if applicable)
  • Designation date and data source
  • Nation (England, Scotland, or Wales)
