Several banks have been reporting issues to complaints tracker Downdetector as their online apps suffered an unexpected outage this morning.

Customers of Santander, HSBC, NatWest and Halifax have been left unable to access their bank accounts due to a Sky technical outage.

All nine lenders’ websites and mobile app banking services were partly down on Friday morning, with issues reported from 5am.

The outage is related to an ongoing Sky broadband and Wi-Fi technical failure.

A Sky spokesperson told said: “Sky Broadband customers may be experiencing issues when trying to access some websites this morning. We’re investigating this as a priority and we’re sorry for any inconvenience.”

Customers reporting access issues to complaints tracker Downdetector

If you’re a Sky customer, you may be able to work around the issue by turning on 4G or disconnecting mobile data. If your mobile data is run by Sky, you can try connecting to an alternative Wi-Fi network instead.

Lloyds Bank, which owns Halifax, said its online banking services are running as normal for all non-Sky customers.

The outage first began with 450 Santander customers reporting access issues to complaints tracker Downdetector in the early hours of today. At present, 97% of those on the complaints forum have reported issues with Sky internet.

Half of those who reported issues said online was down and a further 49% said they could not access their mobile banking.
