To those who earlier replied to a question about paying PEA with BKK that it is not possible you are wrong. I pay PEA every month with BKK but you gotta use the web version of BKK. In the PEA app you select BKK - then log on on the web version BKK and you will see the amount and everything else is already filled out and you just approve it - quite easy and only takes a couple of minutes but it is stupid that you can't use the BKK app. Krungsri app doesn't work either.
