First, for most purposes, it doesn’t really matter what year your bike was made.
Second, I was curious and I Googled. There’s little information about this particular model, and I can’t find an exact match.
That said, my guess is that the frameset is from the early 2000s, probably pre-2004. Raleigh USA’s 2004 catalog shows a Professional model with an aluminum frame and carbon seat stays. By my recollection, aluminum with carbon stays had a brief moment of popularity around that time. Your frame does look like an aluminum frame, but it doesn’t look like it has carbon seat stays. So, let’s guess pre-2004.
The components look like Campagnolo Centaur or Chorus. In the early 2000s, those were all polished silver components. That corroborates that this was an early 2000s frame. I doubt those components came stock, however. Nearly all OEM specifications were Shimano components.
I’m less familiar with Mavic wheels, but those look like the first or second generation of Ksyrium SSC wheels. Again, those were an early 2000s wheelset.
Side note: you need to close that front brake. There’s a small sliding button on the levers near where the brake lever pivots. Push it in.
