I just found Azimo earlier today as I'm pretty sure world remits charges have increased recently... Worldremit vs Azimo Azimo by far the best option for now..
The limits on WorldRemit have increased recently, the maximum you can send in one transaction from a credit /debit card is £1000 which makes the 6.99 fee a little more bearable. But yes I think they did increase fee's recently.
World Remit are very reliable and I am happy with they service, but am using Azimo at the moment because of the cost of sending.
