The campaign is based on a series of detective style adverts, loosely based on the writings of Raymond Chandler, that are designed to show how far the lenders sales force will go to make the approval process go smoothly.
David Broadhead, mortgage development manager at NatWest, said: "We did well in 2001, but we want to take our proposition on to the next level in 2002. We want to differentiate ourselves from other lenders in the market. Lenders tend to base their adverts on their rates and while our rates are in the top quartile the major difference for us, according to the intermediaries we have spoken to, is our sales proposition.
"We more than doubled our relationship managers in 2001 and now have around 80 people in total."
