I’ve a UK account and the apply pay top up limit for me is 250. Can I increase that? Thabnks
In a word, no. It’s a limit 
set. There’s no language anywhere that leads me to believe that a user can unlock a higher limit. That’s the limit until decides otherwise.
As I understand it, Freetrade would rather people didn’t use Apple Pay and Google Pay because of the transaction fee that Apple/Google charge. They’d much rather people used bank transfers, which are much cheaper (not free, the ‘merchant’, i.e. Freetrade, has to pay a fee there too, but it’s much less). Freetrade is a low-fee broker so they need to keep an eye on costs!
