First Complete and Pink are calling for brokers to check their back books and make sure consumers understand their remortgaging options before the end of the year.
The firms say that £28bn of fixed rate mortgages are up for renewal by the end of the year.
A First Complete statement says: “Given the number of people coming off fixed rate mortgages by the end of the year, brokers need to work with their clients to find the right product that will suit changes to their lifestyle.
“As such, First Complete and Pink are urging brokers to take action now.”
First Complete and Pink mortgage manager Karen Hedges says: “As 2016 draws to a close, brokers must continue to be proactive. Advisers mustn’t assume the customer will just pick up the phone to them.
“Today, there are strong opportunities for brokers to help borrowers across the UK to reconsider their current mortgage deal, and potentially save them money on a monthly basis.
“What’s more, it is also a prudent time for brokers to talk to their clients about their protection needs as there is a real opportunity to strengthen client relationships.”
