When buying or selling, you should meet in-person to see the item and exchange money. The purpose of the Gumtree “For Sale” category is to encourage face-to-face, local, trading. For personal ease and safety, always ensure you take someone with you. If you're answering a home service ad, ask the poster to produce identity and proof of qualification before inviting them into your home.
Never send your item before receiving the money
Never send or wire money to sellers or buyers. This includes never mailing a cheque or using payment services like Bidpay, Western Union or Money Gram to pay for items found on Gumtree. It is our belief that these forms of funds transfer are favoured by fraudsters.
Gumtree doesn’t offer any sort of buyer protection/ payment programs. Any emails you receive that talk about such systems are scams, even if they may have the Gumtree logo. If you receive any emails promoting these services, please report it to us.
Please also take special care when buying expensive items like mobile phones, laptops, plasma TVs, airline tickets and even tickets for shows/gigs. When buying airline tickets we suggest you take the seller's name and ticket number, check the ticket exists and take responsibility yourself for changing the names.
When buying tickets for events please be aware that some tickets may have terms printed on them that limit the ability of the original buyer to sell them to someone else. Some event tickets, e.g. Glastonbury Festival 2007, may also feature a photograph of the original buyer which may mean that anyone other than the original buyer may be refused entry to the event.
Never provide your personal or banking information (e.g. credit card number) to others over the Internet.
Make yourself aware of common scams and fraud - see our Scam Watch section. Do not believe the promise of large sums of money for your help in any task.
Report to us any attempted fraud or suspicious emails, ads, or other activity by community members. In case of fraud or illegal activity, we also recommend that you report it to the Police.
Use common sense. If something sounds too good to be true, it probably is.
