Tips
* Use Templates thanks to Chetanojha and separate them with tabs

* Use Plastic jackets thanks to QuickSam

* Include a self addressed special delivery return envelop

* Bank Draft or Postal Order: There are many instances on this forum of Debit/Credit cards being lost by their owners or being rejected by banks due to the high amount (in spite of being instructed to allow a large payment to the UKBA earlier). If you are opting for a postal application spend a few pounds more, get yourself a bank draft/postal order and save yourself the stress.

* Enclose a photocopy of all the documents in a separate plastic jacket. Make life easier for your case-worker.
* Don't stress. Check processing timeline sticky thanks to Sushdmehta
