You must register commercial trailers over 750kg and all trailers over 3,500kg before you can drive through some countries in Europe.

You can use this service to:

  • check if you need to register a trailer to take it abroad
  • create an account to register your trailer or trailers
  • manage your registered trailer details - for example if you sell or scrap a trailer

If you have an abnormal load trailer, you must also get a keeper’s certificate. Keep it in your vehicle to show at border crossings.


It costs:

  • £26 to register a trailer for the first time
  • £21 to issue a new registration certificate for a new registered keeper
  • £10 for a replacement UK trailer registration certificate
