200,000 GBP questions

[marcnj97]

I have a couple of questions:
1. Should the whole amount of 200,000 GBP be transferred from my personal account to the business account after the business starts to work?
2. Should the investment of 200,000 GBP be made at once, or this amount of money can remain at the business account and be used for the business purposes?
3. Should the whole amount of 200,000 GBP be invested, even if the business requires less? If "yes", then within what period of time the entire investment of 200,000 GBP should be made?
