Update from the government re my enquiry. Case closed lol.
Good afternoon Mick.
Many thanks for your recent e-mail which has been passed to the Approvals Technical department in order to reply to your concerns. Firstly, please accept our apologies for the delay in replying, the department is extremely busy at this time.
Any “new” trailer, be it manufactured by a company or self-built, will be required to have an approval before it is first used on a public road. Small trailers however are not as such “registered”.
For trailers manufactured in small numbers or for self-builds, these would usually be approved through Individual Vehicle Approval (IVA). The IVA scheme is administered by ourselves (the DVSA).
Please follow the link below for more information on the IVA Scheme;
**LINK**
The technical requirements that a trailer must meet can be found in the IVA Inspection Manual for Trailers;
**LINK**
For your trailer with a GVW not exceeding 750kg, this would be classed as a Category O1 Trailer.
Once you have completed the build, you must apply for an inspection using the correct application form (IVA1T);
**LINK**
This must be submitted electronically on our Technical Application Submission (TAS) system;
**LINK**
You can find a list of IVA test sites and the Category of vehicles they can accommodate in the interactive map in the link below (best viewed in Chrome or Firefox);
**LINK**
The fee for an IVA inspection on a Category O1 trailer is £70.00.
Once your trailer meets with the requirements, you will be issued with an Individual Approval Certificate (IAC). This will then permit you to use your trailer on a public road.
I hope that you find this information helpful and apologise again for the delay in replying.
Many thanks & best regards,
Steve Bardsley | DVSA Vehicle Approvals Technical Team
