Supply a large goods trailer for use on the road


You must apply to the Driver and Vehicle Standards Agency (DVSA) for permission if you supply large goods trailers for use on the road.

This is called a ‘letter of consent’ and applies to ‘final suppliers’.

You need a letter of consent if your trailer:

  • is for carrying goods and weighs more than 1020kg when it’s not carrying any goods or other items (known as ‘unladen weight’)
  • is a semi-trailer

You don’t need a letter of consent if your trailer is listed in Schedule 2 of the Goods Vehicle (Plating and Testing) Regulations.
