Shopify can't split a UK shipping zone by postcode, so a Highlands surcharge or an islands-only rate needs carrier-calculated shipping. This app does it with the rates you already have. Add a zone from a preset such as Scottish Highlands & Islands, Northern Ireland or the Channel Islands, or type your own postcode areas, districts, ranges or sectors. Then choose what happens there: show only certain rates, hide some, or don't deliver. Rates can change by order value and be renamed per zone.

• UK presets: Scottish Highlands & Islands, NI, Isle of Man, Channel Islands, IoW
• Show only, hide or block your existing rates per zone, no carrier accounts
• Rules by postcode area, district, range or sector, e.g. IV, KW1-14, IP6 8
• Different rates by order value, with spend thresholds per zone
• Postcode tester and checkout log show what customers actually saw
