Accord has warned of delays processing residential mortgage applications after recording its busiest two days in 17 years.

The lender is urging brokers to avoid phoning unless they absolutely have to.

It comes after the intermediary arm of Yorkshire Building Society withdrew its 90 per cent loan-to-value products this week following a surge in demand.

In an email to advisers, Accord requests that brokers log into its portal in order to track cases:

“Thanks to our two busiest days in 17 years of business, we are dealing with a huge volume of applications. 

“To enable us to process your applications as fast as we can, if you’re looking for an update, please use the following channels to allow our teams to focus on working through the pipeline.

“Our website homepage always has up-to-date service figures at the top.

“There’s no need to call unless your case is outside our current service standards.”

The website is currently showing the average application to offer timeline is 10 days.

It adds: “There are currently long waiting times for phone lines, so please don’t get in touch unless there’s something about your case we need to know.”

For queries on new applications, Accord urges advisers to use its webchat tool.

The lender says its buy-to-let service is not affected.
