I bank with SABB but for 8 months my company and SABB cannot get it right so I want to throw in the towel and move to Riyadh Bank.
Can anyone vouch for their internet banking and ease of remitting funds to Blighty?

And another thing - those tossers, sorry, wonderful guys, at SABB/HSBC hit me 5-6% on a currency transfer - not by charges but by reduced exchange rate. No wonder HSBC was not affected by the finacial crisis ....

Try going to one of the exchange places and see what their rates are. If they are better, work out the value of your time and see if it's worth taking the cash out and doing it manually.

In terms of transferring money from KSA to UK, have a read of this thread, it may help:

AFAIK, the OP has since had some better luck with the whole process and did say he would post an update.

I've only ever used SABB, so can't vouch for Riyadh Bank.
