"The current rate conditions allow us to offer a highly competitive rate on our ten-year fix, which is significantly below the 3.05% market average rate. "
The product comes with a £995 product fee and free standard valuation.
Borrowers can also make annual overpayments by up to 10% without charge, and the mortgage is portable.
Jemma Anderson, mortgage manager at Accord, said: “We’ve seen demand for longer term fixes increase recently, which is possibly due to economic and political uncertainty as well as the potential upward trajectory of the Bank Rate.
“So we felt it was important to offer a mortgage which will give borrowers long-term value for money and provide them with the reassurance of knowing exactly what their monthly repayments will be for a decade come what may.
“The current rate conditions allow us to offer a highly competitive rate on our ten-year fix, which is significantly below the 3.05% market average rate.
“Life is constantly changing, so the new mortgage is portable which gives borrowers the flexibility to take their deal with them if they decide to move home before it comes to an end.
“Locking into a deal for this length of time is a big decision, so brokers can add value for their clients by helping to make sure they are aware of all their options before signing on the dotted line.”
