Over time, the partnership may evolve into a white-labelled service, an arrangement Enterprise Finance has with other networks.
Danny Waters, CEO of Enterprise Finance, said: "We are delighted that the NACFB has chosen Enterprise to be its exclusive provider of secured loans and will ensure that all its members receive a first-class service that they can be proud of. There was intense industry competition to secure this partnership and the fact we won represents a significant step forward for the Enterprise Finance proposition and brand.
"In the current market, secured loans are increasingly seen as a simple and effective way to raise capital. Our role is to ensure that the growing demand for these products is met."
Adam Tyler, chief executive of NACFB, added: "We chose to work with Enterprise Finance because they are hugely respected in the industry, have unrivalled experienced in this area of the market and came highly recommended by some of the UK's largest broker networks. We are confident that they will bring real value to the table for our members through a market-leading service proposition and we look forward to working with Danny, Harry and the team in the months ahead."
