Beware renewal of your licence if you had a 25Kw restriction on it.
Passed my test in Nov 03, sent my licence to DVLA due to change of address, came back with cat A effective from Nov 05! Only recently noticed this when insurance company asked for confirmation of years riding.
Went into DVLA Northampton, they recognised fault,( I'd photocopied my old licence and pass cetificate). They spoke to Swansea, who said that's when restriction was taken off licence so that's the category date. All paperwork is now on way to Swansea DVLA, will update when I've heard back from them.
