A spokesperson for RBS Group has said that all banking services are back to normal for customers of RBS, NatWest and Ulster Bank.
Online banking services appear to be working again on the RBS, NatWest and Ulster Bank websites.
Previously, the log-in pages of all three banks were displaying an error message.
It is not clear whether card services are working again.
RBS, NatWest and Ulster Group agreed to compensate customers in March after many experienced problems using their bank cards and with online and phone banking services.
RBS later released a statement blaming the problems on a "hardware fault".
In June 2012, another apparently unrelated software issue left millions customers unable to access their accounts, costing the banks some £125 million in compensation.
The reported technical glitches with RBS, NatWest and Ulster Bank could not come at a worse time for customers hoping to do some Christmas shopping.
Today has been dubbed 'Cyber Monday' as it is expected to be the biggest day in the calendar for e-commerce.
All three banks, which are part of the Royal Bank of Scotland Group, have had technical issues in recent days:
- 28th November - Ulster Bank website was down for over two hours
- 29th November - RBS and NatWest mobile banking was down for around seven hours
Twitters users are reporting problems using their RBS and NatWest cards and using online banking services.
NatWest, RBS and Ulster Bank have said they are having "some technical issues" after numerous reports on Twitter from angry users.
