Thousands of Hargreaves Lansdown customers have experienced a power cut since Thursday evening 19 March.
The outage is due to a major IT failure that hit the UK’s largest retail investment platform during a period of extreme market volatility.
The Bristol-based firm, which manages more than £170bn for around two million clients, confirmed on Friday 20 March that technical issues were affecting its website and mobile app.
While there is no problem with customer data and assets, the company made it clear that there is “no evidence of any cyber incident or data breach.”
After the outage, investors heavily criticized the platform as they were unable to trade amid volatile markets triggered by escalating conflicts in the Middle East.
Consumer lawyer Gary Rycroft said affected customers may have legal claims in negligence, but financial loss would be challenging if markets recover.
The disruption comes after weeks of upheaval for the investment platform, which introduced new fees applicable to new clients on March 1, sparking a wave of transfer requests to rival firms.
Officials have apologized for the inconvenience and promised to restore full service as soon as possible, requesting users to check the website for more updates.
