The lender offers a range of products from standard residential and buy-to-let (BTL) to self-build, semi-commercial and unusual properties.

It will lend on new-build and shared ownership properties – including flats – throughout England, Wales and central London, up to a maximum of six storeys.

As part of the agreement, members of the mortgage club will have access to the lender’s range of offerings.

Melanie Spencer, head of MCI Mortgage Club, said: “Newbury Building Society is a very versatile lender and really gets to understand the borrower’s needs with its manual underwriting approach.

“Our members will be able to benefit from Newbury’s wide range of mortgage products and we look forward to working with the team.”

Karen Smith, sales manager at Newbury Building Society, added: “We have a dedicated intermediary helpdesk and are always happy to discuss cases as we have a flexible approach to lending and take a common-sense view on underwriting.

“Brokers are assigned their own case handler from application through to mortgage offer and are on hand to assist in any way they can.”
