In reply to sunny123:
Lots of good advise already given here, just adding my personal experience.
I am, like you, at the learning stage and have been for a while, having now climbed for well over ten years. I am still very keen despite having discovered climbing late in life, in fact I am completely gripped. Unfortunately I can't climb very often, only when I have the luxury of free time, hence the very slow learning curve and status of perennial Beginner/Punter.
I am not attracted to the Club scene, I am self conscious and weary of joining much younger climbers for fear of slowing them down, not climbing well enough and also not having much in common with younger people apart from climbing. that is why I end up quite often climbing alone as I need my fix as often as possible, which is more often that the only partner I have at the moment (also tied down with commitments).
As a consequence, I have solo top roped many trad and sport routes, I have solo led trad multipitch (low grades only, accidentally discovering that I DO love the self relaiance and solitude) all of which has helped me to improve technique, both in terms of movement and ropes management/knots/abseiling/gear placements/anchors, etc...
Before setting out I have read everything I could find on the subject (hrs of research and reading, but I enjoyed that too...), then practiced the techniques "on the ground" and in "safe" environments (not in the mountains alone, instead using trees in the garden etc...)
I have at the same time practiced self resque techniques such as Prusiking (or jumaring if you want to use ascenders), passing knots on abseils, etc.. this was also a great opportunity to learn other techniques such as pulleys, escaping the system, etc.. as these are often described in self-rescue books/tutorials and are useful skills to have, in general even if not relevant to soloing. I have put up a lot of practice setting anchors and, whenever climbing or practicing I have ALWAYS used back up systems and redundancy to minimise the chances of something going horribly wrong!
I then started going out for single pitch top rope solos, experimented with a few systems until I found what I liked best (completely personal, you will have to find yours too) and familiarised until it felt comfortable. Only at that stage I started to "work the routes and concentrate on the moves, as the technicalities of soloing where becoming natural rather than requiring high concentration. I later started to go for short multipitch routes (2 or 3 pitches as the technique is quite laborious and time consuming). Having tuned up a workable and safe system I now venture into longer climbs, 8/10 pitches. When I do this I never climb at my limit, staying well within my comfort zone ( for me that translate to grades Diff and VDiff. To put it into prospective, many experienced climbers will be happy to solo those grades unroped).
This is my personal experience, it has given me many unforgettable experiences and so far it has worked for me, I have survived and learned a lot in the process. This doesn't mean that it is the way to do it or that it will work for everyone.
Be aware that soloing in general ande specially learning to climb in this way is both highly dangerous AND slow as there will be no one there to correct your mistakes or help you if you run into troubles. Another downside is that You might also learn "bad habits" that, when later corrected by experienced climbers, will seem hard to get rid of.
In retrospective I think that when starting out it is worth to find partners, as already suggested by others. Your climbing will improve much faster and you will be safer.
Whatever you chose to do, If you are into trad climbing, the UK is a great place to be in terms of climbing possibilities, tradition and history!
Good Luck! Enjoy and climb safe
