UK Stage 2 Plate Requirements: VIN, Weights & Approval

When a vehicle is completed through a formal multi-stage process, an additional manufacturer plate may be required for that stage. This guide explains the key checks for converters without treating every campervan, tipper or recovery body conversion as automatically subject to the same rule.

Stage 1 versus Stage 2

The original vehicle manufacturer may supply a complete vehicle or an incomplete chassis for a specialist bodybuilder. A later manufacturer can complete that vehicle as part of the approval process. The details and responsibilities depend on the vehicle type and the approval arrangement.

Does every conversion require a second plate?

No single answer fits every conversion. Check the vehicle category, registration and approval status, whether the chassis was incomplete, whether the work is part of a multi-stage approval, and whether masses or other particulars have changed. Seek advice from the relevant approval authority, technical service or suitably qualified professional for the specific build.

VIN and manufacturer identity

Multi-stage plate rules generally preserve traceability to the base vehicle and require the correct authorised manufacturer identification. A plate printer must not invent or alter a VIN, display a different converter as the responsible manufacturer, or imply that printing the plate grants approval.

Weights and plate content

There can be differences between the information shown on the chassis manufacturer's plate and the converter's additional plate. Confirm gross vehicle mass, train mass and axle masses using the correct approval and technical records rather than measurements or assumptions. The required order, inscription durability, location and secure attachment are also relevant.

Useful records to prepare

• VIN and base vehicle particulars
• Converter company and authorised contact
• Applicable approval number, stage and vehicle category
• Approved weight values and evidence supporting changes
• The proposed plate layout and fixing method

The GOV.UK IVA guidance for vans and DVSA inspection manuals are the starting points for checking the current rules. This page is general information, not approval advice.
