After trading for over four years as a hobby business I decided to go full time and of course needed a proper business bank account. starling came recommended by a friend who uses them so I tried to apply but was rejected without explanation or recourse. All attempts to get further information have been blocked/ignored. 24/7 customer support is worthless if their only answer is "we refuse to tell you that". I have trading history, equipment and assets already and so have zero risk - I wasn't even applying for any kind of credit. They're simply not interested in model trains it seems. I applied to Monzo and was snapped up in under an hour.
