Accident at roundabout
Hi, I'm new to this forum first of all so hello to you guys. I would appreciate some help and advice from yourselves as I am not sure where to go with this one. I was involved in a car accident yesterday at a roundabout. I was in the inside lane and was taking the 5th exit as shown on the image below. I was indicating right the whole time and there are no road markings on the roundabout or on the exit i came off from to indicate which lane cars should be in.
The van on the inside lane was taking the exit as shown below and hit into my drivers side door with force. I pulled up immediately and took his details, he was adamant it was my fault and I was adamant it was his. There was absolutely no damage to his van and a substantial amount of damage to my drivers side door. There were witnesses but no one that stopped at all.

I apologise for the extremely messy drawing.
I'm not sure who is in the wrong here and I would like an idea before contacting insurance. Also my no claims are unprotected, if the insurance see it as 50/50 or in my favour am I still likely to lose these? Any advice/assistance would be really appreciated.
Thanks
