The new platform will allow applicants to complete the process in a matter of minutes, with a decision usually given within 24 hours.
NatWest says the platform can offer larger digital loans than any other UK bank and will build on the success of its ESME Loans platform, which provides loans of up to £150,000.
Alison Rose, CEO of commercial and private banking at NatWest, said: “We are continuously looking for innovative solutions to meet the ever-evolving needs of our business and commercial customers.
"Our commitment to helping businesses in the UK access funding is at the heart of everything we do and we want to support them. Accessing larger loans, quickly, is vital, and this new end-to-end digital lending platform allows us to offer just that.
"The scale and pace of changes in customer behaviour is like nothing we have seen before, and we’re incredibly proud of this new proposition which shows our commitment to serving our customers better.”
