-There is a big chance that in the letter you also have to state that you offer to be fully responsible, might he cause any financial damage (violence, burglary), or when something happens to him (hospital-treatment).
-They might ask you to attach your pay-slips of yur salary together with the letter, so that they can see that in case anything happens, you are ABLE to take responsibility. If you dont have a high enough paid job, this may have some negative effects, however, you could also let your mum or dad fill in the invitation-form so that they will be responsible
-He probably has to show too that he has enough to go back to in Turkey (payslips of a good job, registration at university, ownership of real-estate).

I dont know where you can get such a letter in the UK, in Thye Netherlands you can buy them at the civil council of the city. I know of British people who wrote the letter themselves too, included name of invitee, duration of stay, reason of stay, financial responsibility etc.
