How Much Do Cyber Attacks Really Cost UK Businesses?

Cyberattacks have been identified as a significant financial burden for UK businesses, with the average cost per incident exceeding £10,000. The rise in online threats correlates with the increase in remote and hybrid working since 2020, as hackers often exploit less secure internet connections used at home or in public spaces.

According to government reports, 43% of UK businesses and 30% of charities experienced cyberattacks in the past year. The shift towards hybrid working environments, with 28% of UK adults working in such settings between January and March 2025, has intensified these threats, as reported by the Office for National Statistics.

Uswitch Broadband has highlighted the security challenges posed by this change in work habits. Max Beckett, a broadband expert, noted that unlike secure office networks, many home or public internet connections lack essential security measures such as encryption, firewalls, and monitoring, making them more vulnerable to cybercriminal activities. Beckett emphasized the importance of measures like updating firmware, using strong passwords, and employing VPNs to safeguard company data.

An unsecured broadband network is characterized by inadequate security, such as no password, a weak password, or lack of encryption. This vulnerability allows unauthorized access and data interception. Max Beckett warns that small businesses and remote workers are particularly at risk, as a single security breach can lead to financial loss, reputational damage, and legal issues under UK GDPR regulations. The absence of robust protection in home or shared workspaces facilitates access to sensitive information by cybercriminals.

During Cyber Security Awareness Month, Uswitch Broadband's Max Beckett shared practical advice for reducing cybersecurity risks. He recommended securing Wi-Fi networks by removing personal details from network names, setting strong passwords, and ensuring WPA2 or WPA3 encryption is used.

Beckett also advised the use of VPNs in public settings, as they create a secure encrypted connection, making data interception more difficult for hackers. Keeping devices updated is another crucial step, as updates fix vulnerabilities that hackers exploit. Regular software updates are one of the most effective defenses against cyber threats.

Strong passwords are essential, as weak ones can be easily cracked by automated tools. Beckett suggests using a combination of uppercase and lowercase letters, numbers, and symbols to enhance password strength, particularly for Wi-Fi networks connecting multiple devices.

Impact of Hybrid Work on Cybersecurity Costs

The transition to hybrid work has introduced new cybersecurity risks. Many employees now use personal devices and connect via home routers that are not regularly updated, increasing the exposure to cyber threats. Uswitch Broadband reports that cyberattacks cost businesses an average of more than £10,000 per incident, with small businesses facing higher recovery costs. The need for robust home network protection is critical to reducing these financial impacts.
