ISA transfers can take anywhere up to 30 days. We will request funds for a project anywhere between 1-6 weeks post project raise. Therefore, as you cannot guarantee funds will be in your account by the required date with an ISA transfer, we recommend waiting until funds have arrived in your account before making a pledge in this instance. This is to avoid the disappointment of successfully pledging, however then having to have your pledge cancelled as a result of the required funds not being available.
