Once you have accepted a bid and made payment for the service offered, the funds are held by DeliveryD2D until the transaction has been completed.
DeliveryD2D feedback is your most valuable tool in determining the trustworthiness of a transporter, as feedback is left by other DeliveryD2D users after every transaction. Working in the same way as the feedback score on eBay, you can leave comments for the transporter, as well as a positive, neutral or negative feedback rating.
HGV and operator licenses can be checked here.
If the transport provider claims to be a member of a trade association, look up that association as most have an online directory. Use this to look up the transport provider there to verify their claims. False claims of membership to a trade association are taken very seriously by DeliveryD2D.
If the transporter advised that they are a limited company you can check the records at Companies House
Transport providers also state their level of insurance cover on their profiles.
Once a transport has been verified his profile is amended to show the verification of the transporter.
