RFL on 2018 Euro 5 van

[Twincam Escort]

Because I knew there was no immediate chance to use my recently acquired van I SORNed it straight away.
I've since tried to find out how much the road fund licence fee will be and I'm struggling. DVLAs website wouldnt/couldnt tell me and when I asked the previous owner they couldnt remember either.
I assume prior to the new rules everyone paid the same? Can someone enlighten me please?

Depends on the weight £260 for 3500kg and something like £160 for over
