Where Knowledge Meets Innovation
"Easily block checkouts for remote UK postcodes on Shopify."
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. The app works on every Shopify tier including Basic.
