You were pretty right, I got a mail from the DVLA this morning saying they would transfer the years if it says on my license what date I passed my test, which in my case it does.
Now my quest continues to see the difference in quotes with different licenses!
For anyone interested in the full DVLA mail:
Thank you for your email about exchanging your Dutch driving licence to a GB one.
I should start by explaining that since 1 January 1997 you are no longer required to exchange a valid EC/EEA licence for a GB licence, providing you have passed a test in an EC/EEA country.
You are entitled to drive here on the strength of your EC/EEA driving licence as long as it remains valid up until the day preceding your 70th birthday or for 3 years after becoming resident here whichever is the longer period.
However, if you wish to exchange your licence, please ask at your main Post Office® for a D1 application form and return the form to DVLA with your licence and the relevant enclosures. A fee of £50.00 is required with your application. The EC/EEA licence will be returned to the Issuing Licensing Authorities.
Important Note: If your EC/EEA licence was issued in exchange for one from another country, this may be valid for driving in GB for only 12 months and you may not be able to exchange it for the GB equivalent.
Holders of community licences with vocational entitlements who live in GB must by law, register their details with DVLA.
Drivers of small vehicle may also register, if they wish. Drivers who register will receive their licence back together with a UK counterpart licence. This would enable them to take advantage of the fixed penalty system for road traffic offences instead of having to go to court. If you would like to apply for a GB paper counter part to accompany your Dutch driving licence, please complete a D9 application form. Please see D100 information leaflet available at the Post Office® for further information.
Turning to the next part of your enquiry. I should point out, if your Dutch driving licence shows the date you passed your car test in Netherlands then this information will be recorded on your GB driving licence. However, if the date you passed your car test abroad is not recorded on your Dutch licence then we will use the date your licence was issued in GB on your licence instead.
With regards to insurance matters. Unfortunately, we cannot comment on this. If you require any information relating to your insurance certificate/policy, please contact your insurance company and they will be able to assist or advice you further.
