Transactions from start of 'glitch' will be given priority
ULSTER Bank is working through a backlog to ensure all delayed transactions go through in the right sequence.
This means that if you carried out a number of transactions in the past week, the first to go through will be the oldest one -- i.e. if you were due to get paid last Wednesday and your mortgage was due out of your account yesterday, your wages will be paid into your account first and then your mortgage will be paid.
Because the oldest transactions are being tackled first, any recent transactions will be waiting in a queue.
Brian Hutton of BH Consulting, which specialises in IT security, said it was taking a long time because millions of accounts and millions of transactions had been affected by last week's "glitch".
The numbers are so high because there is a "shared platform" between Ulster Bank, RBS and NatWest.
"It will be an automated job in as much as possible and they will be doing it in sequence," he explained.
But Mr Hutton said he would expect people to query transactions and fees for several months even after the backlog is cleared.
While the bank is saying 99pc of RBS and NatWest accounts in the UK have been updated, RBS said Ulster Bank customers continue to suffer "unacceptable delays".
