Be wary of requests to pay via bank transfer, especially from overseas buyers. Insist on meeting in person for transactions and checking the item thoroughly before payment. Avoid deals that seem too good to be true, and never share personal or financial information via email or text message. Be particularly cautious of fake listings using stolen images.

Arrange to meet in a public place during daylight hours. Take a friend or family member with you. Let someone know where you are going and when you expect to be back. Avoid meeting at your home or theirs, especially for initial meetings. Consider using a 'safe exchange zone' if one is available in your area.

Always test the item before buying if possible. Check for physical damage, such as cracks or dents. Ask about the item's history, including how long it has been used and whether it has been repaired. Ensure you receive any original accessories, such as chargers or cables. For mobile phones, check the IMEI number to ensure it hasn't been reported lost or stolen.

When buying from a private seller, your rights are more limited than when buying from a business. The item must be 'as described' and of 'satisfactory quality' (taking into account its age and price). However, you don't have the same rights to return an item simply because you change your mind. It's crucial to inspect the item carefully before buying.

Report the listing or user to Gumtree immediately using the 'Report' button on the listing page or user profile. Provide as much detail as possible about your concerns. You can also report suspected fraud or scams to Action Fraud, the UK's national reporting centre for fraud and cybercrime.
