The products are available up to 75% LTV and are available with both fee and fee-free options.
They include a 10-year fix at 5.29% with a £999 fee, and a 10-year fix at 5.69% with no fee, both available at 75% LTV.
The new deals will be available exclusively direct.
The lender has also reduced rates across a number of products in its fixed rate range by up to 0.40%.
Reductions include a cut of 0.30% on its three-year fix available up to 75% LTV, now at 4.39% with a £999 fee.
Meanwhile the lender’s five-year fix at 85% LTV has been reduced by 0.40% to 5.29%, with no fee.
James Hillon, head of mortgages at The Co-operative Bank, says: “We’ve already been recognised as the best provider of longer term fixed rate mortgages so the introduction of a new 10-year fixed rate range is the next step in giving borrowers even more choice.
“For those looking for the security and peace of mind offered by a product fixed for a longer term, this provides a welcome boost.”
