What to Do If You Find Knotweed in City of Glasgow

If you discover or suspect Japanese knotweed on a property in City of Glasgow:

  3. Start treatment promptly — Early intervention limits spread and reduces long-term costs
  4. Obtain an insurance-backed guarantee — Essential for property transactions and mortgage applications
  5. Know your legal obligations — You must prevent knotweed from spreading to neighbouring properties

If you're buying in City of Glasgow
