Cyber Security in Construction: Preparing for the Cyber Security and Resilience Bill

Cybersecurity might not have been top of mind for many in the construction industry, but that’s changing fast.

In April 2025, the UK government published the Cyber Security and Resilience Policy Statement, outlining the confirmed and proposed measures to be included in the Cyber Security and Resilience Bill. This marks a significant shift in how digital risks will be managed across critical industries, including construction. As our sector continues to embrace digital tools for everything from project planning to communication and data management, the risks of cyber threats are becoming increasingly urgent.

For construction companies, this bill signals the need for stronger safeguards to protect sensitive information, comply with mandatory incident reporting, and ensure adherence to industry standards for cybersecurity. The digital systems we rely on, from cloud-based software to BIM models, are valuable tools, but they also make us targets for cybercriminals.

Why Cybersecurity Is a Real Risk in Construction

Construction firms are becoming more reliant on technology. From mobile project management software to digital drawings and cloud-based document sharing, much of the industry’s day-to-day activity now depends on IT systems.

This shift has made the sector a growing target for cyberattacks. Whether it’s ransomware locking down sensitive project files, or fraudulent emails posing as clients or suppliers, the risks are real and rising. A successful cyberattack can halt projects, compromise data, damage reputation and lead to financial penalties.

What the New Bill Will Require

The Cyber Security and Resilience Bill is still in development, but the direction of travel is clear. It will likely include:

  • Compulsory cyber risk assessments for all businesses operating in critical or high-value sectors

  • Mandatory reporting of cyber incidents to regulatory bodies

  • Baseline security standards for digital systems and supply chains

  • Greater powers for enforcement agencies to audit and penalise non-compliance

Construction firms involved in public sector work or strategic infrastructure are particularly likely to be affected.

Steps Construction Companies Should Be Taking Now

Although the bill is not yet law, preparation should start immediately. Here are five practical actions firms can take:

1. Assess Your Cyber Risks

Identify the systems and data your business relies on. This includes project files, payment records, architectural plans, and supplier communications. Evaluate where your vulnerabilities lie, whether through outdated software, limited access controls or unsecured devices.

2. Improve Basic Cyber Hygiene

Make sure your internal systems follow recognised best practices. Use strong, unique passwords and two-factor authentication. Keep all devices and software updated. Back up essential data regularly, and limit access to confidential material based on employee roles.

3. Train Staff to Spot Threats

People are often the weakest link in cyber security. Invest in training that helps staff identify phishing emails, suspicious links and fraudulent messages. Training should be ongoing and relevant to both site and office-based teams.

4. Evaluate Your Supply Chain

Construction projects involve dozens of third parties. If one supplier or subcontractor has poor cyber defences, it could put your business at risk. Review your key partners and consider introducing minimum security standards as part of your procurement process.

5. Create a Cyber Incident Response Plan

If a breach happens, you need a clear process. Your plan should cover containment, internal communication, legal reporting and how to keep projects running while systems are restored.

Cybersecurity might not be visible on-site like scaffolding or materials, but it’s now fundamental to a secure and professional construction operation. As the Cyber Security and Resilience Bill moves forward, companies that prepare early will be better protected, more trusted, and more competitive.
