Cybersecurity is now a building risk: What UK organisations must control in 2026
Cybersecurity used to sit with IT.
In 2026, it affects buildings, operations and facilities management directly.
Across the UK, cyber attacks are increasingly targeting connected infrastructure, smart building systems and suppliers – creating real operational risks for organisations of every size.
What has changed?
Recent reports show the scale of the issue.
One UK security report revealed that millions of attacks are now targeting outdated connected devices and systems still operating inside organisations, including smart cameras and networked infrastructure.
At the same time, the National Cyber Security Centre has warned that the UK could face cyber attacks “at scale” affecting public and private organisations alike.
The government is also tightening regulation through the proposed Cyber Security and Resilience Bill, which increases expectations for infrastructure resilience and incident reporting.
This marks a major shift.
Cybersecurity is no longer just an IT issue.
It is now an operational and facilities risk.
Why this matters for FM and operations
Modern buildings are highly connected.
Facilities teams now manage systems including:
- CCTV and access control
- HVAC and BMS systems
- Smart sensors and monitoring tools
- Energy management systems
- Contractor and visitor platforms
If these systems are outdated or poorly controlled, they become entry points for attackers.
And the consequences are operational:
- Loss of building access
- Disruption to services
- System shutdowns
- Data exposure
- Reputational damage
The growing concern is not only internal systems.
It is third-party suppliers and contractors.
Recent cyber incidents have shown that attacks increasingly spread through vendor relationships and connected infrastructure.
This means FM teams must now think about cybersecurity as part of building resilience.
What this means for different organisations
Small businesses
You are still at risk.
Many attacks now target smaller organisations using older systems or limited protections.
You should:
- Update connected devices
- Use secure suppliers
- Avoid unsupported systems
Medium and large organisations
The challenge is visibility.
Across sites, you need:
- Control over connected systems
- Clear cyber processes
- Supplier oversight
Multinationals
Cybersecurity now affects:
- Operational continuity
- ESG risk
- Governance and reporting
UK expectations are increasing rapidly.
Public sector buyers
Cyber resilience is now a procurement priority.
You must demonstrate:
- Secure operations
- Resilient suppliers
- Controlled infrastructure
Contractors
Contractors are part of the risk chain.
You must:
- Follow secure access processes
- Protect connected systems
- Comply with cyber requirements
What to check now
Start with five key checks:
- Devices – are connected systems updated and supported?
- Access – who can access your building systems?
- Suppliers – are contractors following secure processes?
- Visibility – do you know what systems are connected?
- Resilience – could operations continue during an attack?
Where TPMG FM fits in
This is where integrated FM becomes essential.
At TPMG FM, operational resilience is supported through:
- Controlled contractor management
- Proactive system oversight
- Compliance-focused processes
- Clear operational reporting
As buildings become smarter, organisations need more than maintenance.
They need resilience.
If your organisation needs to improve operational resilience, reduce cyber related building risks or strengthen supplier controls, TPMG FM can help you deliver secure, compliant and future ready FM services.
