I understand it that as long as you have access to funds of £2000 + you should be fine, just make sure you let them see the statements of your current account showing your wages coming in each month and the transfer to your savings account, I would also show them statements of your savings showing the money going into that account each month. We got our fiancee visa just last week and it came within 7 days of applying which was amazing. I had also added a monthly budget plan which I knocked up quick on my computer showing my money going into the account and then listed all my main outgoings and money I transfer into my savings account and then I shown the figure that was left to support my fiancee each month.
I think the main thing is to make it all clear to them and be honest, me personally from the 6 months of statements I submitted the first 3 were showing me in my overdraft sometimes going overdrawn as I was trying to sell a second property and things got really tight, I just made sure I added a covering letter explaining why my account was like that and explained that since selling the property everything is fine. Its normal to worry and I was really stressed about my early bank statements but we got our visa in 7 days so guess I did the right thing.
Best of luck with your application[/I]
