Launched in 1953 by a group of local business people in South Wales, its initial remit was to provide finance for local families.
It continues to cater to South Wales but has now expanded its geographic and demographic scope and provides funding to commercial customers.
According to the lender, it had over 12,000 customers throughout South Wales, the Midlands, West and North of England.
Rob Hopkins, chief operating officer at Family Finance, said: “We are delighted to join the ASTL as the association has such a strong reputation among short-term property lenders.
“Our philosophy at Family Finance is to always try to ensure good customer outcomes and this aligns with the ethos of the ASTL.”
Vic Jannels (pictured), chief executive of the ASTL, said: “I’d like to welcome Family Finance as the latest lender to join the ASTL. We now have more than 40 lender members, representing the vast majority of recognisable brands in the short-term property lending market.
“This strong membership gives us greater influence as an association, helping us to promote the sector, engage with policy makers, and uphold standards.”
There are currently 41 lender members of the ASTL, including Family Finance and The Bridging Group, covering regulated and non-regulated bridging, development finance, refurbishment, ground-up development and second charge loans.
