My question is, if your money is in the UK bank, can you do the transfer in Western Union if you are here?

I don't know how can anybody do that?

Do it online via WU using creditcard/visa/MasterCard. Of course you use your banks home currency then it converts and sends. Cheaper to a bank acc. but has wait time, to pick up in person way more expensive but instant transfer. WU will email you confirmation/ pick up number.

use a hotel address when filling out WU transfer details or use some one you trust who is a local, use their details, they can't get access to the money without MCN/ confirmation number which was emailed to you. Or if you can open a bank acc. and send it directly to yourself.

Use Western Union, you can send the money online and then collect from any post office.

... and other locations. My Bangkok Bank branch does Western Union too and I'm sure I've seen some WU counters in malls in Bangkok.
