Summary: Colocation Cybersecurity in the UK (2026)

• UK legislation shift: The 2026 Cyber Security and Resilience Bill reclassifies data centres as Essential Services, making infrastructure a regulated part of cybersecurity compliance.

•  Cyber threat escalation: The UK recorded over 200 major cyber incidents in one year, with ransomware and supply chain attacks rising sharply across both enterprises and SMEs.

• Regulatory gap closed: New DSIT and NCSC measures require stronger supplier accountability, incident reporting to Ofcom, and adoption of Cyber Essentials baseline protections.

• Infrastructure now critical: Cybersecurity is no longer limited to software. Hosting environments must meet resilience, availability, and physical security standards.

• Supply chain risk exposure: Only around 40% of large organisations assess supplier cybersecurity, making third-party infrastructure a major vulnerability.

• Colocation closes the gap: Dedicated infrastructure, controlled physical access, UK data sovereignty, and predictable performance reduce risks that cloud-only environments cannot f
• ully address.

• IP House alignment: Tier III infrastructure, ISO 27001/9001 certification, and Zero Trust physical security position IP House London in line with 2026 UK cybersecurity and resilience standards.

Introduction

In this new article, we examine recent measures by the UK government to put data centres on a level pegging with energy and water utilities. We also examine cybersecurity measures IP House already implements for UK businesses to protect their data and systems. 

Why are Data Centres Essential Services?

As of March 2026, the UK Government released the DSIT Cybersecurity Newsletter. It revealed that the UK cybersecurity situation was facing a major turning point in early 2025. A core feature is the Cyber Security and Resilience Bill. It is a groundbreaking shift in the protection of infrastructure for UK businesses led by the UK government's strategy. 

Data Centres will be formally reclassified as Essential Services. This effectively places data centre infrastructure on the same playing field and national importance level as energy and water utilities. The reclassification was first announced in September 2024. This new Bill expands upon it. 

The Bill clearly indicates that the UK government considers an attack on a data centre to be a threat to the nation’s productivity and public service delivery. 

What does the CyberSecurity and Resilience legislation mean for UK businesses?

The joint DSIT/NCSC campaign ‘urges SMEs to adopt Cyber Essentials’. The government wants UK businesses to ‘lock the door’ on cybercrime. The new campaign and bill provide practical guidance and methods for businesses to secure themselves against online threats. 

Some of the measures include controlling access to accounts and data and making sure software is always up-to-date. These are areas that cybercriminals commonly exploit, and Cyber Essentials is specifically designed to counter these threats. 

Important Information for UK Businesses on Cyber Essentials and the NCSC

• Businesses can access support, including the Cyber Essentials Readiness Tool (an online self‑assessment to identify security gaps).
• Free 30‑minute consultations with NCSC‑assured cyber advisors to help your business prepare for Cyber Essentials certification.   
• Find out more information on the Cyber Essentials website.

What is the National Cyber Security Centre (NCSC)? 

The NCSC is the UK government’s front-line authority on cybersecurity. It sits under GCHQ in terms of hierarchy. Their role is to protect UK businesses and organisations, infrastructure, and the public from cyber threats.

What does the NCSC do?

• Sets national cybersecurity guidance for businesses and the public sector

• Runs schemes like Cyber Essentials.

• Responds to major cyber incidents

• Advises government and critical infrastructure providers

• Publishes threat intelligence and best practice frameworks

What do the Cyber Essentials changes mean for your business?

Ultimately, your choice of hosting provider is now a matter of national resilience standards. You should choose a data centre that meets the Essentials benchmark. 

What Is the UK Cybersecurity Regulatory Gap?

The Department for Science, Innovation and Technology update (DSIT) is specifically focused on solving a long-standing "regulatory gap". This gap is where data infrastructure falls short of the minimum requirements for cyber resilience. 

In the past, many providers operated with a range of security tiers from low to high. With the new Cyber Essentials legislation, providers of data centre services and hosting are required to manage risks proportionately. Also, cybersecurity incidents must be reported promptly to Ofcom. 

IP House, Already Cyber Security Compliant

At IP House, we are ahead of the game because we knew that this level of regulatory compliance would be necessary with the increase in cybersecurity attacks on UK businesses.

The good news is that our facility in London’s Docklands is built to Tier III standards. That means that if you are an IP House client, your business is already aligned with the standards the UK government is now making compulsory. 

UK Cyber Threat Reaches a Record High

With the NCSC’s Annual review in 2025 revealing that the UK Cyber threat was now at a record high,

“The NCSC’s Annual Review 2025 painted a stark picture: the UK faced 204 nationally significant cyber incidents between September 2024 and August 2025 – a 130% increase on the previous year and the highest number ever recorded. “Highly significant” incidents, those with serious impact on government, essential services, or the economy, rose by 50% for the third consecutive year.”

Rising cyberattacks have fueled the current initiatives by the UK government to make British businesses more resilient in the face of cybersecurity threats. You can read more about the types of cyberattacks in our article: Microsoft Report: 600 million cyberattacks everyday.

Cyber Attacks Can Destroy Businesses Overnight

A cyber attack forced the collapse of a 160-year-old UK haulage firm, showing that even established businesses with existing security measures are vulnerable. Knights of Old entered administration after ransomware corrupted critical financial data, making it impossible to meet lender requirements. 

The incident reflects a wider trend, with major organisations like Marks & Spencer and the Co-op also facing disruption, while smaller firms remain at even greater risk due to limited resources. Experts warn that modern attacks are evolving rapidly, with “ransomware as a service” increasing both frequency and impact. Some key facts about cyberattacks are:

• Real-world collapse: Cyber attack destroyed a long-established UK business despite existing protections

• Data corruption risk: Critical systems and financial data can be rendered unusable, halting operations

• Widespread threat: Large brands and SMEs are both being targeted across sectors

• SME vulnerability: Smaller firms face greater risk due to limited budgets and response capability

• Evolving attacks: Ransomware now combines data theft and system lockout to maximise pressure

As cybersecurity expert Tash Buckley explains, “It really can happen to anyone… for smaller companies, it’s more of an existential issue.”

The Shift to Supply Chain Due Diligence

In light of the forthcoming legislation, DSIT’s latest research indicates that large businesses are improving their internal defences. However, figures suggest that only 40% of big businesses assess the cybersecurity risks coming from their suppliers. 

The 2026 Cyber Essentials Bill aims to fix this prevalent problem by enabling regulators to designate "Critical Suppliers." 

Supply Chain Cyber Attacks Are Rising Fast

The National Cybersecurity Centre warned businesses that now was the time to prepare for severe cyberattacks. They issued a collective call to action for UK businesses to protect themselves against cybercrime and have resilient infrastructure. 

“The NCSC Annual Review 2025 highlights the widening gap between the rising pace of cyber threat and the UK’s collective resilience – and the NCSC’s message is unambiguous: the time to act is now.”

Cyber criminals are no longer targeting organisations in isolation. Instead, they are targeting the ecosystem around them, i.e. the Supply Chain. Suppliers, partners, and service providers have become the easiest entry point into larger, more secure and connected networks.

A single weak link is enough for a cybercriminal to gain entry. If a supplier’s system is compromised, attackers can move laterally across connected environments, gaining access to data, systems, and operations that would otherwise be difficult to breach.

• Entry point risk: Suppliers are often less protected, making them easier targets for attackers

• Lateral movement: One breach can spread across connected systems and organisations

• Operational disruption: Attacks on suppliers can halt production, logistics, and services

• Real-world impact: Incidents affecting companies such as Jaguar Land Rover show how supply chain attacks disrupt entire industries

This is no longer theoretical. Modern business depends on digital supply chains, but those same connections create shared risk. If your suppliers are not secure, neither are you. This is a key area that the new UK government legislation is seeking to address. 

Why Cloud-Only Cybersecurity Is Not Enough: The Fallacy of the Virtual-Only Defence

One prime concern is that most cybersecurity strategies by UK businesses have software as the starting point rather than infrastructure. Companies configure their firewalls, monitor their endpoints and secure their identity controls. However, the infrastructure that lies beneath these measures is often neglected. 

In a cloud environment, you are renting the capability, but you are not controlling it. As a business, you cannot verify who has access to your hardware on the physical level, how the security is implemented on-site and how your systems are managed and prioritised during a cybersecurity incident. 

In recent times, the shift towards colocation services does not mean a business abandons the cloud. It is more about realising that digital security with physical control is limited. If you do not have this physical security and control on the infrastructure, it is a major risk for your business. This is partly what has prompted the new UK bill. 

What the Cybersecurity and Resilience Bill Means for UK Businesses in 2026

The Cyber Security and Resilience Bill has established cyber security as foundational to the operations of UK businesses. It is no longer an IT department issue. In effect, this now means as a UK business:

• Infrastructure is now part of compliance: it is no longer enough to secure applications; the hosting environment must meet defined standards

• Supplier risk becomes your risk: gaps in third-party security are now directly relevant to your own exposure

• Accountability extends beyond your organisation: failure at the provider level can still result in operational and regulatory consequences.

With the new legislation, your hosting provider is now not just a supplier but a core part of your security architecture. 

How Colocation Improves Cybersecurity for UK Businesses

Colocation resolves the problem at the infrastructure level rather than trying to patch over it with additional software. Instead of relying on shared environments, you operate on dedicated hardware within a facility designed for resilience. That allows security to be enforced consistently, not assumed.

• Physical access is controlled and auditable: no unknown variables around who can reach your systems
• Performance is stable and predictable: no shared resource contention affecting uptime or monitoring
• Data remains within UK jurisdiction: reducing legal complexity and improving compliance alignment

This is why colocation is increasingly used for critical workloads. It is not about preference. It is about risk reduction.

How IP House London Meets the 2026 Standards

The key difference with IP House is that its infrastructure already aligns with the direction of the new UK regulations. The IP House Docklands-based facility operates to Tier III standards, with redundancy across power, cooling, and connectivity. That ensures systems remain operational even under stress conditions, which is exactly when security matters most.

• Tier III infrastructure: designed for continuous availability and fault tolerance

• Biometric access and 24/7 monitoring: physical security enforced as rigorously as digital controls

• Infrastructure compliant: For UK businesses, the great benefit of partnering with IP House, London, is that we already meet the new Supply Chain Diligence requirements set down by the UK government. IP House Data Centre is both:

• ISO 27001 certified (Information security, cybersecurity and privacy protection — Information security management systems). This ISO defines how risks are identified, managed, and continuously reviewed
• ISO 9001 certified (Quality Management Systems). This ISO ensures operational consistency and accountability across all processes

• UK data sovereignty: Hosting with IP House’s London-based facility keeps data under UK jurisdiction, reducing legal exposure and simplifying compliance.

What Is Physical Security in Zero Trust Cybersecurity?

Zero Trust is usually discussed in terms of users, logins, and permissions, but that is rarely applied to the security of the physical environment. At IP House London, Zero Trust extends beyond software into the physical layer or facilities themselves:

• Perimeter security: The Docklands facility operates with Grade III intruder detection, anti-climb protection, and tightly controlled access points within one of the UK’s most connected digital hubs

• Biometric access control: Multi-factor authentication and biometric verification remove reliance on keycards, eliminating common vulnerabilities such as tailgating or credential theft

• Continuous on-site monitoring: 24/7/365 CCTV and physical security presence ensure that access is not only restricted, but constantly verified

• Zero Trust Physical Defence: The physical layer is an active part of the security of the building. 

What Are Availability Attacks in Cybersecurity?

Availability Attacks the Primary Threat

“In general, availability attacks are a DoS attack that can delay or completely prohibit authorized individuals to access to certain services at the time when they need to.”

Source: Science Direct.com, 2026 

With an availability attack, if your systems go offline, so does your cyber defence. Therefore, availability is a core aspect of security. Whilst data breaches tend to get more coverage in the media, disruption to services is a more immediate and frequent risk.

Denial-of-service attacks do not need to breach your systems. If systems go offline, monitoring stops. If monitoring stops, threats go undetected. 

Colocation infrastructure at IP House London is designed to handle availability attacks with: 

• Carrier-neutral connectivity: Multiple Tier-1 providers allow traffic to be rerouted when a network path is targeted

• N+1 redundancy: Power and cooling systems remain operational even when components fail, ensuring systems stay live

• High-bandwidth capacity: Infrastructure is built to absorb traffic spikes that would overwhelm standard business connections

Physical Infrastructure and AI Security

AI-driven cybersecurity is often regarded as the next evolution in defence. However, AI systems are only as effective as the infrastructure they run on. Advanced security tools do not fail because they are poorly designed. They fail because the infrastructure beneath them cannot support them when it matters.

High-performance security platforms generate significant heat and require stable, high-density power. Many environments simply cannot sustain that consistently, which leads to throttling, instability, or outright failure under load.

At IP House London, the environment and physical infrastructure are engineered to support these demands:

• 2MVA power capacity: Supports high-density compute workloads without degradation

• Precision cooling systems: Maintain optimal operating conditions for sustained performance

• Schneider Electric StruxureWare DCIM: Provides real-time monitoring and optimisation of the data centre environment

Conclusion: Cybersecurity Now Starts with Infrastructure

“Cyber security is now a matter of business survival and national resilience.”

Clearly, cybersecurity is no longer just about protecting systems at the software level. The new UK government cybersecurity measures and proposed legislation now recognise that the physical infrastructure is also vital to cybersecurity

The infrastructure where those systems live, how they are controlled, and whether they can operate under pressure, are all determining factors in protecting against a cyberattack. 

Colocation services at IP House London close that gap in cybersecurity by providing a controlled, compliant environment where security is enforced at every level.

By moving critical infrastructure to IP House London, your business will have cutting-edge cybersecurity protection that aligns with the UK government’s 2026 resilience standards.
