House deposit savings source of money -

homi

Got myself in a real muddle with my savings  / house deposit account , was on top of everything until a few years ago and few family related issues to deal with . 

My savings all over the place and the  problem is that is a large amount which is over the 85k so cannot hold it one place .

I have 

Natwest business account ( soletrader ) which I run my online store from where the vast majority of funds has come from which has a large sum sitting earning no interest .

Tescos Savings account with the majority of my money ( at the savings limit )  all which was transferred  from my natwest sole trader account to earn some interest  ( .71%) .
 

I have two cash isas ( natwest and coventry building society ) with around 20k in each . 

Lloyds bank which i use for most daily things like shopping . 

 
Chase account ( opened a couple of days ago ) which I wish to load up to the max .  

90% of the funds is from my natwest sole trader / business account but  my concern is that when I come to finally ( if ever ) put a deposit down there wont be any questions to where the money has come from and why it was transffered .

Is there any surefire way of keeping track of the transactions ,or will the statements be enough .  

Any help would be appreciated . 

The majority of the money can be traced back to a natwest account which was opened around 7 years ago , it still have a large sum earning no interest ( .10% ) which I want to transfer into chase   , life and worry has got in the way of buying a property but dont want to keep chasing higher interest rates in case it costs me in the long run .

Any ideas on the best course of action . 

Is there anyway of keeping a track which will be good enough for the mortgage company to prove where the money has come from .

There's no need to hold it all in one place, mortgage lenders and solicitors etc are capable of adding things up!
