Assalam-0-Alaikum
bro my personal suggestion is to go somewhere else rather than coming UK
i m 21 and living in uk for last 3 months and looking for job like a dog who is hungry for food. subah 9 o'clock per nikalta hu aur gher main kbhi 9pm kbhi 6p per ghusta hu last two months se but abhi tak kahi se bhi call nahi ay aur naa he job milli (i dont have refrence neither i know any1 here) toilet ,kachra chunna, newpaper distribute kerna kissi bhi kisam ki job nahi mill rahi and mere visa kay 0oper 10hrs per week mention hua wa hay. don't ask me how irritating live is here in UK.
this was my personal experiance but mere college kay bht se lerkay hain jo mashallah week kay 250 to 300 pound bhi earn ker rahay hain. but i don't know why me and some other fellows are not getting job may be depends upon luck.
well 300,000 students ko visa mila hay aur in two years yahaa ki govt is figure ko chaaaant ker 10,000 may le ker aygi aur unhi students ko visa milayga jo bht he zada extra ordinary hongay aur psw bhi khatam ker dia hay.
may be i am wrong somewhere but as i told you b4 this was my personal experience.
good luck mate.
