I booked a test for in 5 months time, then signed up with this site (a bit dubious) . The following day (monday) I never left the DVLA website. This site only gives you a choice of 3 test centres and I knew I had about 6 to play with, all the same distance away and I did manage to get an earlier date for 2 months time at a test centre not chosen with this site - but it would have been on my birthday and I would have been away on holiday and not able to take my son, therefore having to rely on someone else. I used the DVLA site so much it blocked me!!!!! I started stressing a bit, not knowing how long DVLA would have me blocked, then ping- I got my first text from this site, at a nearer test centre, within 2 weeks so I said "book" and they booked it, then I got a confirmation from DVLA to say it was booked. Hippee, let hope he passed this time and doesn't get the gastapo Instructor like last time!
