But it does not work with uk bank when buying. Only option.is bank transfer which is complicated I'm worried if I mistyped 1 little letter when typing address or reference I will loose all money from my account
Well seems like you are indeed a newbie and fits your name.
Anyway. Not sure what you are looking for, but seems like you are looking for an online wallet that has the feature of being able to buy bitcoins at the same time. You can check out:
coinbase (depends on which country you are in, they allow you to buy from their platform)
spectrocoin (not very sure with this, just check it our yourself)
Generally, it is best to just buy from localbitcoins then store it in your own wallet like bither (ios and android) or electrum (android).
