The UK construction sector is a growing target for ransomware, invoice fraud, and supply chain attacks - with firms of all sizes increasingly reliant on connected systems, cloud platforms, and digital project delivery. Government contracts require Cyber Essentials, tier-one contractors are flowing it down to subcontractors, and BIM frameworks demand baseline information security. Certification protects your tenders, your projects, and your reputation.
Construction accounted for one in five UK ransomware incidents in recent NCSC reporting - firms with remote sites and dispersed IT are prime targets
Cyber Essentials is required for government contracts involving sensitive data - without it, your tender is excluded before evaluation
Tier-one contractors increasingly mandate CE for subcontractors - it is becoming a supply chain entry requirement across UK frameworks
From government tenders to supply chain compliance and BIM security, Cyber Essentials addresses the core cyber risks facing construction and infrastructure firms.
UK government contracts worth £5 million or more that involve handling sensitive or personal information require suppliers to hold Cyber Essentials. Public sector clients - including local authorities, NHS trusts, Highways England, and education bodies - increasingly mandate it at lower thresholds too. Without certification, your tender is excluded before it is evaluated.
Tier-one main contractors - Balfour Beatty, Kier, Morgan Sindall, BAM, and others - are flowing cyber security requirements down to subcontractors and supply chain partners. If you access a common data environment, receive project drawings, or connect to a client's systems, Cyber Essentials is increasingly a condition of appointment.
ISO 19650 and its predecessor PAS 1192-5 require organisations to manage information security risks across the BIM process. Cyber Essentials provides the baseline technical controls that protect common data environments, design models, and project information from unauthorised access - the minimum evidence most framework operators accept.
Construction firms are high-value targets for business email compromise and invoice redirection attacks - criminals intercept payment instructions between contractors, subcontractors, and clients. A single compromised email account can result in six-figure losses. The five Cyber Essentials controls block the attack vectors used in the vast majority of these incidents.
UK-registered construction firms with annual turnover under £20m that achieve Cyber Essentials are eligible for free cyber liability insurance up to £25,000 through IASME - at no extra cost. For SME contractors operating on tight margins, this is meaningful cover that would otherwise be a significant budget line.
Construction projects generate vast amounts of sensitive data - architectural drawings, structural calculations, cost plans, client specifications, and personally identifiable information. A ransomware attack that encrypts project files mid-build can halt an entire programme. Cyber Essentials ensures the baseline controls are in place to prevent it.
Certification verifies that five essential technical safeguards are in place - the controls the NCSC identifies as blocking the majority of opportunistic cyber attacks targeting UK businesses.
Control 1
Establish a secure network perimeter to block unauthorised external access to your firm's project servers, financial systems, and site-connected devices.
Control 2
Remove default passwords, disable unnecessary software, and harden every device - including site laptops, tablets, and any equipment connecting to project networks.
Control 3
Ensure staff and subcontractors only access the systems and data they need - limiting the blast radius of any compromised account across your projects.
Control 4
Deploy anti-malware protection to stop ransomware and spyware executing via phishing emails, malicious attachments, or compromised USB drives brought onto site.
Control 5
Keep all operating systems and software patched within 14 days of a security release - closing known vulnerabilities before attackers can exploit them across your fleet.
The right certification level depends on your firm's size, contract requirements, and the sensitivity of the projects you work on.
Not sure which tier your firm needs? Contact us and we will advise →
Tier 1
A verified self-assessment questionnaire reviewed by an approved assessor. Meets government tender requirements, satisfies tier-one supply chain obligations, and provides the baseline BIM security evidence most frameworks accept.
Tier 2
Adds an independent technical audit and vulnerability scan. An approved assessor actively tests your systems to verify controls work in practice. Best for firms working on sensitive infrastructure or MOD-adjacent projects.
We understand that construction companies operate across multiple sites with dispersed IT, site-based workers, and tight project deadlines. We work around your programme - guiding your firm through Cyber Essentials from initial scoping to issued certificate without disrupting live projects.

UK Government - Procurement Policy Note
Government contracts involving sensitive or personal information require suppliers to hold a current Cyber Essentials certificate. This applies across construction, infrastructure, and facilities management procurement.
ISO 19650 / PAS 1192-5 - BIM Security
The UK BIM Framework requires organisations to manage information security risks across the project lifecycle. Cyber Essentials provides the baseline technical controls that satisfy this requirement for most framework operators.
Tier-One Supply Chain Requirements
Major contractors are mandating Cyber Essentials across their supply chains. Framework agreements such as Pagabo, Procure Partnerships, and CCS increasingly list it as a minimum requirement for appointed subcontractors.
UK GDPR - Article 32
Requires appropriate technical security measures for personal data. Construction firms hold employee, subcontractor, and client data - the five CE controls directly satisfy this obligation.
Free Cyber Insurance via IASME
UK-registered firms with annual turnover under £20m are eligible for free cyber liability insurance up to £25,000 through IASME upon achieving Cyber Essentials - at no additional cost to the certification fee.
Construction firms often have a more complex scoping picture than office-based businesses. Here is what you need to consider.
Scoping can be nuanced for construction firms with multiple sites and mixed device ownership. We help you define the right scope before you start the assessment.
