Members of MMA will now have access to the lender’s offering, which provides specialist finance to business owners, homeowners and landlords, and car owners.
Aldermore bank offers deals to customers with small deposits, limited equity, those who are self-employed and who have experienced credit issues in their past.
This follows the addition of Brightstar and The Mortgage Lender earlier this year.
Nick Parker, head of intermediary distribution at Aldermore bank, said: “Homebuyers are more diverse and unique in their financial circumstances than ever before, and COVID-19 has made buying conditions more challenging.
“It has never been more vital that the industry unites and works together, to share best practices, challenge long-held assumptions, and bring the market forward as it evolves into the exciting and rapidly growing digital space.
“We must let those that aspire to be a home owner in the future or those that want to change their housing situation know that the mortgage market is open for business, and working for them.
“From a new buyer raising a small deposit, and self-employed to the last-steppers and private landlords managing big and small portfolios, there are now options and choice for all to find pathways to get to where they want to be.”
Rob Griffiths, director of the MMA, said: “I’d like to welcome Aldermore as the latest lender to commit to the Mortgage Market Alliance.
“As Nick says in his quote – it is more important than ever that the industry unites and works together, and we provide a channel for a collaborative effort to raise consumer awareness around the diverse range of options available in the mortgage market and the benefits of professional advice.”
