The ability to use Faster Payments now will depend on the stage at which both your bank and the beneficiary's bank are at. Some banks will be receive-only for now, and some will be send/receive enabled.
Even if your bank can send, there is no guarantee that their online infrastructure is in place for roll-out to retail customers, so the ability to actually send payments won't be available to you just yet.
How much money do you need to transfer, and to which bank? Would a cash deposit in a branch not be quicker?
