A spokeswoman for Accord said: “Due to competitor movements within the market we have received an unprecedented number of applications and wish to ensure we maintain our service levels.”
She added Accord repriced the week before to catch up on itself because again, several lenders had repriced upwards then, leaving the lender exposed.
The new range will launch on Thursday and rates are expected to go up.
Ray Boulger, senior technical manager at John Charcol, said: “Yorkshire’s brands, including Chelsea, Norwich & Peterborough and Accord have been very competitive in the five to ten year market.
“However, I suspect they’ll come up with something new on Thursday. But Accord has been a market leader for the intermediary market, so if they price upwards it will increase the differential between the lender’s intermediary and direct channels,” he added.
