I can transfer 100k in GBP free too. BACS limit is £250k. Once I exceed that I have to fall to CHAPs which will cost me about £25 and has no limit. Banking is mostly free in the UK.
You're correct, sorry. AIUI there's a higher limit for corps/govs too. Banks often have lower limits than these but I've no doubt they'll lift them if there's need.
For those not familiar, FPS offers 2h (normally instant) transaction speed.
Having bank transfers in 2019 so slow is outrageous. It's the time when trading bots produce millions in a split second. But bank transactions require hours and days. And they dare to call them fast!
Eh, when does it really matter? The only time I care about speed is when buying something, and the more expensive that something is, the less fast it needs to be.
