For any visit-visa you should, in general, give as much evidence as possible that you´re planning to return to the country where you reside now, and that you can finance your whole trip incl. returning to your country without recourse to public funds. The more the visa-officer believes that you´re genuinely planning to "only" visit, the more likely you will get the visa.
As such it´a always good to give as much as possible of the following papers:
- proof that you own land/real estate
- proof of current employment (incl. leave letter or anything that proves that you will resume your work after the trip)
- return flight ticket
- funds supporting your stay
- travel health-insurance
- invitation from someone in destaination country (incl. statement that the person will host you and/or pay for you)
- anything else at all which indicates that you plan to return
Which of these are a requirement for the UK I don´t know. Hope someone will give a better reply.
Until then I recommend you change the title of your post as per
