Been with NatWest business banking for around six years. That is neither a recommendation or a criticism.
You get allocated a business manager who in my case would love me if I took loans, credit card machines etc etc.
However, my business didn't want any of that even at the start. I am there to make money for my business not there's, which is a concept he doesn't seem able to grasp very well.
In fact I now use a PayPal credit card machine which I recharge the PP fees out and avoid the reoccurring monthly charges from NW.
Most of my business is with clients who pay by BT so we both avoid the charges.
As it is, my business manager is never, ever, ever , available even on his mobile and is quite frankly pants. So I pretend he isn't there and that works fine.
The rest of it is fairly painless, branch staff at a number of branches I use, admin, statements etc all ok.
If you need a replacement card that can take a couple of weeks and if they make a cock up on processing you get the usual banal call centre crap. Just keep asking for the next manager above them until you get what you want.
