Now some sense is being written.
Yes Barclay's are crap. Many people have reported Nationwide as being very good for transferring money and catering for ex-pats as a whole.
I think though that is some confusion regarding ATM withdrawals and money transfers.
ATMs connect to a worldwide system and the owning bank can give whatever rate at their ATM that they choose. The rates are updated every 120 minutes or less.
Bank of Ayudayha is usually at rthe top of the GBP list but not always.
The difference between the highest rate and the lowest rate is about 35 Satang for each 100 GBP.
Your issuing (home) bank may add another withdrawal charge which you need to be aware of. You will only see that if you have internet banking or you get your statements sent to you. They acquiring bank (ATM owner cannot tell you. They don't know.
Money transfer is different thing altogether. The sending bank and receiving bank must have an agreed rate that caters for fluctuations that will occur in the time it takes to transfer the money. Organizations like SWIFT and CHAPS dictate those rates. Nearly all banks will add on their percentage and then the greedy bastards add a transfer fee, which is double what they pay and to add insult to injury some even charge a commission set fee. All transaction are a separate entity.
There is no such ting as a cyber rate outside the imagination of internet bankers.
Now back to ATM withdrawals and to put this "discussion" to bed once and for all.
The rates for ATM in Thailand for GBP accounts is right now.
Number 1. Siam City 57.18
Number 2 Ayudhya 57.15
Number 10 TMB 56.81
This means that 100 GBP will get you 5,718 Thai Baht at Siam City and 5,681 Baht at TMB. This is a a difference of 37 Baht. 10,000 GBP would have difference of 370 Baht.
Of course you can never guarantee getting those rates unless you have a hand held and park up outside the ATM all day.
I have just spent a considerable amount of time researching and checking this information for the benefit of all readers so please refrain from arguing unless you have alternative information that conflicts and you have the source of that information.
My information comes from CHAPS (BofE), RTGS (BofE), Nationwide and Bank Bangkok. (And of course the reference web site:

BTW. One thing that has not been mentioned so far is the one off 20 - 30 Baht withdrawal charge that all Thai banks make if you withdraw cash from their till and your account is not at that branch.
I wish you a Merry Christmas and a Happy New Year. Just when I got Ramadam out of the way.
