Data centres are becoming one of the most important construction markets around London, but the latest Government updates show that the sector is no longer only a story about land, steel, MEP capacity and planning. It is now also a story about power contracts, cyber resilience, board-level accountability and supply-chain assurance.
On 7 July 2026, the Government published a cluster of digital and energy policy updates covering cyber resilience, the governance of the Digital Markets Unit and the development of the Great Britain Corporate Power Purchase Agreement market. Taken together, they point towards a more regulated and more closely scrutinised digital infrastructure economy.
For London construction, the message is practical. Data-centre growth depends on the ability to secure electricity, deliver high-voltage infrastructure, manage digital supply-chain risk, protect operational technology and prove that contractors and suppliers can operate inside a more cyber-conscious procurement environment.
The key construction message is clear: data centres are no longer just large MEP-heavy buildings. They are power-secured, cyber-sensitive, digitally regulated infrastructure assets, and that changes what clients may expect from contractors, designers, suppliers and specialist subcontractors.

What Changed?
The most direct construction signal comes from the Government response to the Corporate Power Purchase Agreements call for evidence. Corporate Power Purchase Agreements, or CPPAs, are long-term electricity purchase agreements between a generator and a corporate electricity user. For large electricity consumers, they can support price certainty, low-carbon procurement and investment planning. That matters for data centres because electricity is not a secondary operating cost. It is the asset. A data-centre development without a credible power strategy is not simply a scheme with a utility problem; it is a scheme with a viability, programme and investment problem.
The Government response shows that interest in CPPAs is cautiously positive, but that barriers remain. Respondents highlighted credit requirements, collateral, bespoke negotiations, hidden costs, non-commodity charges, grid connections, regulatory uncertainty and the need for clearer market information. For construction teams, that points to a major change in project risk. The power strategy is moving upstream. Developers, funders and contractors increasingly need to understand grid availability, onsite generation potential, private wire options, substation works, procurement lead-in and long-term electricity exposure before the site is treated as deliverable.
At the same time, the Government’s Cyber Resilience Pledge shows that cyber risk is being pushed towards board-level responsibility and supply-chain assurance. The pledge asks organisations to strengthen governance, use National Cyber Security Centre services and take a risk-based approach to Cyber Essentials across supply chains.

Why This Matters to London Construction
London and the wider South East sit at the centre of the UK’s digital infrastructure pressure. The West London, Slough, Hayes, Heathrow, Docklands and M25 corridors are already associated with data-centre demand, fibre routes, logistics access and major power constraints. That makes the construction challenge different from a conventional commercial development cycle. A normal building project can often treat utilities as a key workstream. A data centre cannot. Power availability, power resilience and electrical infrastructure define the asset from the beginning. Grid connection, substation capacity, switchgear, generators, UPS systems, battery storage, cooling and integrated commissioning all become core delivery risks.
The Government’s CPPA response reinforces this direction. Long-term electricity procurement is becoming part of business resilience. For data-centre developers, that means power strategy may sit alongside planning, land, funding and construction procurement as a critical investment gate. For contractors, this changes pre-construction. It is not enough to price the shell, frame, envelope and services in isolation. The real delivery risk may sit in grid reinforcement, statutory undertaker coordination, long-lead electrical equipment, energy procurement assumptions, cooling design and the contractual interface between construction completion and operational readiness.

This policy shift connects directly with LCM’s previous analysis of London’s data-centre critical infrastructure market, the Court Lane data centre campus in Iver, and wider National Grid constraints affecting construction delivery.
Power Risk: The New Front-End Construction Question
The Government response describes CPPAs as a route to secure low-carbon electricity supplies at stable prices. Respondents saw long-term price certainty as one of the main benefits, but also identified barriers including credit requirements, collateral, legal complexity, non-commodity costs and uncertainty around wider electricity market reform. For data-centre construction, this matters because power uncertainty can reshape the whole delivery model. If a developer cannot secure commercially acceptable power, the construction programme may slow, the design may change, the phasing strategy may shift or the investment case may weaken.
Private wire and onsite arrangements were identified by respondents as among the most cost-competitive CPPA structures, but difficult to deploy at scale because of proximity, land and tenancy constraints. That is highly relevant around London, where suitable land is constrained and competition between housing, logistics, infrastructure and digital uses is already intense. Sleeved CPPAs remain more accessible, but respondents also raised concerns about hidden costs and complexity. That matters where a data-centre project depends on a long-term energy strategy that must satisfy operators, investors, funders, tenants and technical teams.
The practical construction implication is that power due diligence is becoming an acquisition-stage issue. Developers and contractors need earlier answers on connection capacity, reinforcement works, substation land, easements, statutory undertaker interfaces, high-voltage design, energisation dates and the consequences of delayed grid readiness.
The Hidden Programme Risk: Power Before Building
In a conventional development, a delay to utility works is painful. In a data centre, it can be existential. The building can be structurally complete but commercially unusable if the power, resilience systems and commissioning sequence are not ready. That creates a different risk profile for contractors. Main contractors, MEP specialists, civil engineering teams and utility contractors may all be working around a power-critical path that is partly outside their direct control.
Long-lead equipment is another pressure. Switchgear, transformers, generators, UPS systems, cooling plant, controls and specialist electrical packages can affect programme certainty before site works begin. If procurement does not align with grid and energisation strategy, the programme can become exposed very quickly. For London data-centre schemes, this strengthens the case for early-stage technical coordination between developer, power consultant, DNO, IDNO, MEP designer, main contractor, commissioning team and future operator.
Cyber Risk: Why Construction Supply Chains Should Pay Attention
The Cyber Resilience Pledge is voluntary, but the direction of travel is important. The Government wants cyber security to become a board-level responsibility. It also wants organisations to use NCSC tools and take a risk-based approach to requiring Cyber Essentials across supply chains. For the construction sector, that last point is the most important. Supply-chain cyber assurance may move from being a technology-sector issue into construction procurement, especially where contractors are working on data centres, public-sector frameworks, critical infrastructure, utilities, transport, healthcare, defence, telecoms or digitally connected buildings.
Data-centre construction is particularly exposed because the project environment is highly digital. Common data environments, BIM models, access control, commissioning records, controls integration, building management systems, fire systems, security systems, operational technology and handover documentation all create digital attack surfaces. A cyber incident during construction could affect more than emails or office systems. It could disrupt project data, compromise drawings, delay procurement, affect access-control systems, expose client information, interfere with commissioning evidence or damage trust between client and contractor.
This is why cyber resilience is becoming a construction delivery issue. The supply chain that builds digital infrastructure may increasingly be expected to prove that it can protect the digital systems, data and evidence created during delivery.
Cyber Essentials Could Become a Procurement Filter
The Cyber Resilience Pledge asks organisations to take a risk-based approach to requiring Cyber Essentials certification across their supply chain. It also asks signatories to audit Cyber Essentials coverage across the entire supply chain and present that audit to the board. That is significant for construction. If large clients, strategic suppliers, technology companies and infrastructure operators adopt this approach, the requirement may flow down into subcontract appointments, framework agreements, consultant terms, MEP packages, security packages and specialist commissioning roles.
The immediate impact may be felt most strongly by firms working on mission-critical projects. Electrical contractors, controls specialists, security integrators, fire and life-safety contractors, BMS specialists, ICT installers, commissioning managers and FM transition teams may all face stronger cyber-assurance questions. For SMEs, the risk is being caught late. A subcontractor may be technically capable on site but lose access to work if it cannot satisfy cyber-assurance requirements during prequalification. Cyber Essentials may therefore become part of the evidence pack needed to work on higher-value digital infrastructure projects.
Digital Markets Governance: The Wider Signal
The Government also published a Memorandum of Understanding on the governance of the Digital Markets Unit between the Department for Science, Innovation and Technology and the Department for Business and Trade. The DMU sits within the Competition and Markets Authority and oversees the digital markets regime under the Digital Markets, Competition and Consumers Act 2024. This is not a construction regulation in itself. A contractor pouring concrete, installing containment or commissioning switchgear is not suddenly regulated by the Digital Markets Unit because of this MoU.
However, the wider direction matters. Government is formalising how it oversees digital markets, strategic technology firms and the digital economy. Data centres sit physically inside that economy. They are the buildings, power systems and resilient infrastructure that allow cloud, AI, digital services, media, finance, retail and public services to operate. For construction, that means digital infrastructure is increasingly policy-relevant. Data-centre schemes may be judged not only as local developments, but as assets linked to national resilience, economic growth, digital competition, energy demand and cyber security.
What This Means for Contractors and Developers
| Risk Area | What Is Changing | Construction Impact |
|---|---|---|
| Power procurement | Large electricity users are looking for long-term price certainty and low-carbon supply routes. | Power strategy becomes part of project viability and early-stage due diligence. |
| Grid connections | Respondents to the CPPA call for evidence highlighted grid constraints and connection uncertainty. | Connection risk can affect programme, procurement, phasing and funding confidence. |
| Cyber governance | Cyber security is being framed as a board-level responsibility. | Major clients may expect clearer cyber controls from contractors and suppliers. |
| Supply-chain assurance | The Cyber Resilience Pledge promotes a risk-based approach to Cyber Essentials across supply chains. | Cyber Essentials may become a practical prequalification requirement for specialist packages. |
| Digital handover | Construction data, commissioning records and operational systems are increasingly sensitive. | Poor control of digital records could create security, compliance and handover risk. |
| Critical infrastructure status | Data centres are increasingly viewed through national resilience and digital infrastructure policy. | Planning, procurement and client expectations may become more demanding. |
The London Delivery Pressure
London’s data-centre market is shaped by geography. The most attractive locations need access to power, fibre, transport, labour, logistics and customer demand. But those same locations often face land constraints, planning pressure, competing development uses and overloaded infrastructure. This creates a hard delivery equation. The more strategically important the data-centre asset becomes, the more pressure there is to deliver quickly. But the more power-intensive and cyber-sensitive the asset becomes, the more front-end assurance is needed before construction can safely accelerate.
For contractors, this means data-centre work may look attractive but operationally demanding. The market offers major opportunities for civils, utilities, remediation, structural works, envelope, MEP, controls, cooling, fire, security and commissioning specialists. But it also demands stronger coordination, more disciplined documentation and better understanding of digital and power-related risk. The construction firms that benefit most may be those that can combine physical delivery with evidence control, cyber-aware systems, power infrastructure competence and credible supply-chain management.
Why This Is Not Just an IT Story
The Government’s cyber messaging is clear that cyber resilience is not just an IT issue. For construction, the same point applies. On a data-centre project, cyber security connects to site systems, design information, client confidentiality, commissioning data, access controls, operational technology and the integrity of handover records. A construction company does not need to be a software business to create cyber risk. It only needs to hold sensitive drawings, connect to a client platform, manage access credentials, operate site networks, handle commissioning data or appoint suppliers who do the same.
That is why cyber requirements may increasingly sit inside procurement questionnaires, contract schedules, project execution plans, BIM protocols, common data environment rules and handover requirements. In practical terms, the question for contractors may become: can you prove that your people, systems and suppliers can protect the digital evidence and operational interfaces created during delivery?
What Contractors Should Watch Next
The first area to watch is whether Cyber Essentials becomes more visible in construction prequalification. The Cyber Resilience Pledge is voluntary, but large clients and strategic suppliers can turn voluntary commitments into practical supply-chain expectations.
The second area is power due diligence. Developers should expect funders, operators and major contractors to ask harder questions about power certainty, connection dates, substation strategy, long-term energy procurement and whether CPPA structures are relevant to the project’s operating model.
The third area is digital handover. Data-centre clients may increasingly expect better control of commissioning records, asset information, access credentials, controls documentation, cybersecurity evidence and operational readiness information.
The fourth area is procurement language. Contracts may begin to place clearer obligations on contractors around cyber controls, supply-chain certification, incident notification, secure data handling and compliance with client security requirements.
The fifth area is skills. Data-centre delivery already requires specialist MEP and commissioning capability. The next stage may require more cyber-aware project managers, document controllers, BIM teams, package managers and commissioning specialists.
Construction Examples
A data-centre developer considering a London-edge brownfield site may now need to test grid connection, private wire potential, substation land, CPPA options and long-term electricity cost exposure before treating the project as commercially deliverable.
A main contractor bidding for a mission-critical scheme may need to demonstrate not only technical delivery capability, but also cyber controls, secure document management, supply-chain assurance and incident-response processes.
An MEP subcontractor installing controls, switchgear, BMS or security systems may face tougher questions around Cyber Essentials, access permissions, software updates, supplier credentials and commissioning data protection.
A smaller specialist supplier may find that cyber certification becomes a route into higher-value work, while failure to prepare could become a barrier to appointment even where the firm has strong technical site capability.
Evidence-Based Summary
Data-centre construction is moving into a new phase of risk.
Government policy is not only supporting digital growth. It is also strengthening expectations around cyber resilience, digital-market governance and long-term power security.
For London construction, this means data-centre delivery will increasingly depend on power certainty, grid coordination, cyber-aware procurement, secure information management and specialist MEP capability.
The opportunity is substantial, but the delivery model is becoming more demanding. Contractors that treat data centres as ordinary buildings with larger plant rooms may underestimate the real risk.
FAQ: Data Centres, Cyber Resilience and Construction
Why do Government cyber updates matter to construction?
They matter because construction supply chains now handle sensitive project data, connected systems, access controls, commissioning information and operational technology. Cyber weakness can disrupt delivery and damage client confidence.
What is the Cyber Resilience Pledge?
It is a voluntary Government-backed pledge asking organisations to strengthen cyber resilience through board-level accountability, NCSC Early Warning registration and a risk-based approach to Cyber Essentials across supply chains.
Could Cyber Essentials become important for construction suppliers?
Yes. Where major clients adopt the pledge, Cyber Essentials may become more visible in procurement, particularly for data centres, critical infrastructure, public-sector work and digitally connected building systems.
Why do CPPAs matter for data centres?
Corporate Power Purchase Agreements can help large electricity users secure long-term electricity price certainty and low-carbon supply. For power-intensive data centres, electricity procurement can influence viability, funding and operating strategy.
What is the main construction risk around power?
The main risk is that grid capacity, substation works, energisation dates, reinforcement requirements and long-lead electrical equipment can control the project programme before the building itself is complete.
Does the Digital Markets Unit directly regulate construction?
No. The Digital Markets Unit regulates aspects of digital markets under the DMCC Act 2024. However, its governance is part of the wider policy environment in which digital infrastructure, cloud services and data-centre capacity are becoming strategically important.
Why is London particularly exposed?
London and the wider South East combine high data demand, fibre connectivity, cloud and finance-sector proximity, constrained land, planning pressure and major power limitations. That makes data-centre delivery commercially attractive but technically difficult.
What should contractors do now?
Contractors should review cyber controls, Cyber Essentials readiness, supplier assurance, project data handling, power-risk knowledge, commissioning documentation and how early they engage with grid, MEP and operational technology interfaces.
