Hello, and apologies for taking time to get back to you - I've been out of circulation for a while.
To answer your questions, I don't know if I've paid more as a result of opting for DD as DD was the only option. However, I would think not as there was no mention of interest on payments etc. Apparently, the idea behind the altered cost and payment structure was to make it more affordable and accessible for everyone.
My appointment was in Kenilworth. I was told that they were hoping to open new centres in partnership, but there was no mention of where or when. I got the impression that they hoping that it would be soon, but nothing more than that.
The staff I met at Kenilworth were excellent and my assessment was very thorough. I would suggest you try to get an early appointment as you stand a bettwer chance of being seen on time.
Best regards
Stuart
