The Driver Vehicle Licensing Agency (DVLA) must be informed immediately of any
changes to your name and address. This ensures that your vehicle's registration
certificate is up to date (V5C). The process is reassuringly simple. Write the new
information in section six of the V5C - then sign and date the declaration in section eight.
The DVLA must also be informed of certain modifications to your vehicle. These should
be reported in section seven of the registration certificate. Once again, complete the
declaration in section eight too. Reportable vehicle changes include: colour, engine,
cylinder capacity, fuel type (propulsion), replacing or modifying the chassis/monocoque
body-shell, seating capacity, weight of a goods vehicle, wheel plan, body type, vehicle
identification number (VIN), chassis number, and the frame number for motorcycles.
Written evidence may be required to confirm the vehicle modifications. Acceptable proof
might include: product/service receipts, evidence from the manufacturer, an inspection
report provided for insurance purposes, and/or confirmation on headed paper from a
garage. Send the completed V5C to DVLA, Swansea, SA99 1BA. No payment is required.
