Unmarried Partner Visa
I think you will be OK to provide something for every couple of months or every 3 months, spread out over the two years. Try to provide as much as possible esp things that show the address, rack your brains to think of as much of this stuff as you can, doesn't have to be joint bills (tho obviously they are the best) but things of both yours and hers showing the same address. Any insurance policies you have, (travel, pet, gadget insurance, contents insurance, car insurance), do your P60s have your home address on? A letter from your doctor or dentist to show you have been registered at that address is what we got for my husband's application to get his ILR put into a new passport (they may charge a small fee to do you a letter but worth it for the extra proof. Our doctor charged but dentist didn't).
Although the immigration people consider this 'soft' rather than 'hard' evidence, letters from friends and family to say they know you as a couple and how long they have known you (esp good if you can get from colleagues or better a boss, or someone of a professional standing), boarding passes, photos together, and joint invitations to weddings/parties/christenings etc if you still have them.
Don't forget you'll need proof of finances and accommodation both being adequate.
The timing shouldn't be a problem because as long as they are considering your application you are legal (I am assuming switching visas in country between Tier 4 and unmarried partner is OK because I wouldn't know that). Also check if that kind of application can be done in person. If you can, although it costs more, it's great for peace of mind. We went in person to do my hubby's ILR in a new passport (we had an appointment), and we walked out with the new sticker about 4pm the same day.
