Existing HSBC fixed rate mortgage owners can keep the same rate of interest if they sign up for another fixed rate deal with the group.
The deal lasts until the end of April, meaning that customers have until then to renew their deal if they want to continue making steady repayments.
A spokesman for HSBC commented, "This offers allows even more HSBC customers to smooth out any repayment hike once their fixed period comes to an end and creates a sustainable platform for homeownership".
