Coventry was the first lender to introduce pledges in 2007, making six key commitments to intermediaries including a promise not to dual price and not to cross sell.
The new pledge extends this number to seven.
Linked products require borrowers to take additional products such as insurance policies to qualify for a specific mortgage product. This can result in borrowers taking out policies which may not be the most suitable for their needs.
Sales and marketing director Colin Franklin stated: "We were the first lender to make public commitments to the sector and we have remained true to them throughout the economic downturn.
“Through our pledges we aim to help brokers to give the best possible advice to their clients. Saying no to linked products is a logical extension to our pledges which includes no dual pricing and notice of product withdrawal."
Dev Malle, sales and marketing director at PTFS, said "Coventry BS made some brave decisions when it led the lender market in introducing its pledges. Since then, if anything, the pressure for them to pull back on these has never been greater. Instead, it has strengthened the pledges. I sincerely hope my colleagues in the intermediary sector do not underestimate the value of these pledges and appreciate how important pledges such as no dual pricing are at the moment."
Ben Thompson, director mortgages at L&G, said "Coventry's approach towards intermediaries throughout a difficult few years has been completely refreshing. Their pledges are well known and very welcome; of particular note has been their pledge of no dual pricing which one hopes means they benefit from a high level of support from those that don't like this practise.
“The latest pledge of no linked sales is another logical and welcome addition to their overall service and relationship with intermediaries. Effectively they are standing behind their mortgage products which will live or die depending on how good they are, and nothing more complicated than that.”
