"A recent high volume of business has resulted in our service levels exceeding the timescales we are comfortable with."
In a statement, the Society said: "A recent high volume of business has resulted in our service levels exceeding the timescales we are comfortable with. After monitoring the market and careful consideration we are temporarily pausing mortgage applications with immediate effect.
"This is not a decision we have taken lightly and is a temporary measure to enable us to clear our backlog. We are working hard to process our existing pipeline and our aim is to get all cases to offer and completion as quickly as possible."
For cases already in progress, DIPs can be submitted on withdrawn products up to 5pm on Tuesday 9th August and mortgage applications from these previously submitted DIPs can be submitted up to 5pm on Tuesday 16th August.
Last week, Saffron Building Society temporarily paused new mortgage applications on all mortgages excluding self-build.
