When scrapping a car in the UK, you will need ID, such as a driver's license or passport, and proof of address. This is legally required in compliance with the Scrap Metal Dealers Act 2013. 

This regulation aims to deter illegal activities, including selling stolen vehicles, ensure the transaction is legitimate, and protect individuals from scams. While it may be inconvenient to gather these documents, they are necessary for the legitimacy of the scrapping process.

You can scrap a car that isn't in your name, but you must have the owner's explicit permission and provide certain documents. These include the relevant section of the V5C vehicle registration document signed by the owner, a letter from the owner authorizing the scrapping, the owner's photo ID, and a utility bill to establish their identity and residency. 

This ensures that the scrap collector verifies that the vehicle isn't stolen and that you have legal consent to proceed with the scrapping.

It's crucial to have a valid photo ID, like a driver's license or passport, when scrapping your car, as scrap metal dealers are legally required to verify the identity of sellers. 

Ensure that your ID displays your full residential address, or bring a formal document, such as a utility bill, along with your photo ID to complete the process smoothly.
