I've been with Santander for around 4 years now, and I've not really had any problems with them. I left Barclay's after a series of customer service muck ups and moved to Santander (then Abbey) as they offered a 0% overdraft.
I've now got two savings accounts with them with I can access through my online banking - their online banking system is really easy to use as well.
They loose one star for the new daily overdraft charges, but it seems all the other big players do them same thing so can't complain too much!
