At Samut Prakan I had to make a deposit/ withdrawal on the day of application and get an updated bank book along with the Bank letter.

@Tod ********

have called they just said they need copies for the application.

Found a photocopy of all of it but can't find the originals at the moment - will that be ok?

I hope so. I'll get the wife to phone up. Otherwise, I might be needing a divorce certificate as it seems to have been "tidied up" !

I’d beg, borrow or steal the 400k and then give it back after you get the visa.

I have found them very reasonable in Samut Prakan.

His office is Samut Prakan same as mine.

So

@Tod ********

- if my yearly extension runs out mid-July, I just season my 400k in the bank for two months and turn up with all the paperwork, photos etc like usual?

I might be wrong, but my understanding is international bank transfers are FTT and local are SMT. Because some international transfers go to the head office of your bank in Bkk first and are then re-routed to your branch, they don't appear as an international transfer- but a local one. I also believe that Transferwise doesn't actually send the money abroad eg from UK to Thailand but only to a branch in UK. Which is therefore no good for visa extensions as Immigration say the money hasn't come from abroad. But I stand to be corrected.

You might be out of luck as the Thai Embassy in London is shut until further notice. Not sure if a consulate can do it?
