For the correct format you should only add one space to your registration following what it’s written on the certificate. However if it is requested that the plate spacing will be modified, the plate immediately becomes not road legal which is at the owners discretion. This will then become ” a Show plate” and a form will be given out that must be signed suggesting that this plate should not be used on the UK roads and only for display/show. Please refer to your V5 log book if you are unsure or contact us for more information
