In a note to brokers, NatWest said: "We signalled our intention to launch the scheme for intermediaries, after we had implemented changes to our application system to provide you with AIPs which have a soft footprint for your customers."

On purchase products, NatWest has reduced rates by up to 18bps and 10bps and selected two and five-year deals respectively.
