The withdrawal came in to force at midnight last night.
The mutual said it was a temporary measure and that brokers had until midnight on 16 March to submit fully packaged cases where a mortgage illustration had already been produced.
It added that all other products remained unchanged.
Meanwhile, Accord is adding two-year and five-year fixed rate no-fee products to its range of remortgages.
The two-year fixed rate product is available at 65% loan to value (LTV) at 1.66%, while a five-year fix 75% LTV is available at 2.24%.
Both offers come with free standard valuation and free legal fees.
Accord has also reduced rates across selected 65%, 75% and 80% LTV fixed rate mortgages by up to 0.10%.
Accord national intermediary sales manager David Robinson said: “It is proving to be a popular time for borrowers to remortgage at the moment, especially those seeking lower loan-to-value deals.
“We believe that our new remortgage options will prove popular amongst borrowers and the options across the different terms, plus the additional features, will help brokers to choose the best loan to suit their clients’ requirements.”
