The Co-operative Bank and Platform mortgage customer ratings
Mortgages from The Co-operative Bank are only available to new customers through Platform, its intermediary-only mortgage brand.
The Co-operative Bank still offers mortgages to existing customers who are on a standard variable rate, or coming to the end of a mortgage deal.
For this review, we've combined customer feedback on both brands, but we've only looked at Platform's deals to work out whether it's currently a market-leading lender.

Star ratings based on a July 2021 Which? survey of 3504 members of the general public in which 49 people told us that they had their mortgage with Platform/ The Co-Op.
What kinds of mortgages does Platform offer?
When we checked in September 2021, there were 81 mortgages available from Platform. All of these deals were fixed-rate - meaning your interest rate will stay the same for a set initial period. Mortgage terms of two, three and five years were available.
Does Platform offer the best mortgage deals?
Our experts analysed hundreds of mortgages over a four-week period in July and August 2021. They compiled a total of 206 ‘top-10 cheapest deal’ tables based on a variety of borrowing scenarios, and counted how many times each lender featured in a table.
The average number of times a lender made it into a table was 24, but Platform failed to feature at all, meaning it didn't offer market-leading rates in any of our scenarios. (Data source: Moneyfacts.)
