How it sells itself

Surcharge Guard UK lets you block checkout for customers in remote UK postcode areas — Scottish Highlands, Scottish Islands, Northern Ireland (BT), Channel Islands (GY, JE), Isle of Man (IM) and the Isles of Scilly. Toggle zones on or off in seconds. When a customer enters a blocked postcode, they see a clear, error message naming their exact area instead of a generic Shopify error. No theme edits. No scripts.

Tidal sets your shipping rates at checkout by postcode zone, weight and carrier. Surcharge the Scottish Highlands, the islands or Northern Ireland, or hide a carrier where it cannot reach. Show a real delivery date, worked out from your cut-offs, bank holidays and lead times. Route products to the right carrier by tag, and combine a mixed basket into one line, or price each location.

Key points
  • One-click setup — toggle remote zones on or off, changes apply instantly
  • Works on every Shopify tier including Basic
  • Block checkout to configured remote zones
  • Block checkout server-side - cannot be bypassed by customers
  • Set rates by carrier, postcode zone, and weight
  • Add surcharges for remote or hard-to-reach postcodes
  • Route products to specific carriers using product tags
  • Combine multi-carrier orders into one checkout rate
