Trailer logging

You must apply to the Driver & Vehicle Standards Agency (DVSA) for a 'letter of consent' if you are the final supplier of new large goods trailers for use on the road. You need this for any new trailers that the Goods Vehicle (Plating and Testing) Regulations apply to.

When you need permission

You need to get permission if you’re a ‘final supplier’ of trailers. Final suppliers are:

  • trailer manufacturers
  • trailer dealers
  • importers of new trailers

If you’re a dealer or importer, you only have to get permission if it hasn’t already been obtained (if the trailer was built abroad and the manufacturer did not apply).

When you need to get permission depends on when the trailer was manufactured.

Type of trailer When you need permission
New trailers manufactured in a single stage From 29 October 2012
New trailers manufactured in multiple stages From 29 October 2013
Special purpose trailers (trailer caravans, boat launching trailers, gritters, towed machinery) From 29 October 2014

It’s an offence to supply or use these trailers without getting permission first and you could be fined.

If you’re an operator using large goods trailers on the road supplied after the dates above, you don’t need to get permission - it should already have been given.

You can check this by calling the number below:

You might also need to send evidence of vehicle approval depending on when the trailer was manufactured.

  • a European Community Whole Vehicle Type Approval (ECWVTA) Certificate of Conformity (CoC)
  • a UK National Small Series Type Approval (NSSTA) CoC
  • a UK Individual Vehicle Approval (IVA) certificate

More details are in the guidance notes. There is an additional form if you want to apply for consent of multiple trailers.

After you apply

Once DVSA has received your application and confirmed that you meet the requirements you’ll get a ‘letter of consent to supply’.

If your application is rejected, DVSA will send you a letter explaining the reasons why.
