Enterprise Colocation
Enterprise Colocation
Enterprise colocation at scale — 1MW and above — is a fundamentally different market to retail colocation. The operators capable of delivering multi-megawatt deployments with the redundancy, connectivity, and compliance specifications that enterprise organisations require are a distinct and smaller group. The procurement process is more complex, the commercial terms more nuanced, and the consequences of a poorly structured contract more significant. Armason exists to bring structure, market intelligence, and neutrality to enterprise colocation procurement — ensuring that large-scale deployments are matched to operators who can genuinely deliver.
What is Enterprise Colocation?
Enterprise colocation — also referred to as wholesale colocation — describes data centre arrangements at 1MW of contracted IT power and above. At this scale, the commercial and operational dynamics shift substantially from retail colocation. Enterprise buyers typically contract dedicated data halls, suites, or power blocks rather than individual cabinets. Agreements are negotiated directly with operators on bespoke terms rather than from a published price list. Contract lengths run from five to fifteen years. And the technical specification — redundancy architecture, cooling configuration, connectivity requirements, compliance framework — is typically tailored to the buyer’s specific operational requirements rather than defaulting to operator standards.
The enterprise colocation market in the UK and Europe is dominated by a relatively small number of operators capable of delivering at this scale. Global platform providers — Equinix, Digital Realty, NTT Global Data Centers — operate at the top of the market. A second tier of regional operators, many with strong positions in specific geographies, handle the majority of enterprise wholesale demand outside hyperscaler relationships. Understanding which operators in which locations have genuine capacity at the right specification and on the right timeline is the central challenge for enterprise buyers — and the core value that Armason provides.

What Enterprise Colocation Buyers Need
Four requirements that define enterprise colocation at scale.
Power at Scale
Enterprise deployments typically start at 1MW and extend to tens of megawatts for large or AI-intensive requirements. At this scale, power infrastructure — redundancy architecture, UPS systems, generator backup, and grid connection quality — becomes the primary determinant of operational reliability. Operators capable of delivering genuinely redundant power at multi-megawatt scale with contracted SLAs are a distinct subset of the total market.
Compliance and Audit
Enterprise organisations in regulated sectors — financial services, healthcare, public sector — require compliance documentation that many operators cannot provide. ISO 27001 certification, SOC 2 reports, PCI DSS compliance, and the ability to support internal and external audit processes are baseline requirements for regulated enterprise workloads. Armason’s operator qualification process verifies compliance credentials before any engagement begins.
Connectivity Depth
Enterprise architectures typically require multiple carrier connections, access to cloud on-ramps, and in many cases internet exchange access. The number of carriers present in a facility, cross-connect pricing, and the availability of direct connectivity to AWS, Azure, and Google Cloud all affect both operational performance and long-term commercial efficiency. Carrier-neutral facilities are generally preferred for enterprise deployments to avoid commercial dependency on a single network provider.
Commercial Flexibility
Enterprise colocation contracts are long-term commitments with significant financial exposure. Escalation mechanisms, exit provisions, capacity expansion rights, and SLA compensation structures all require careful negotiation. Operator standard terms are structured to favour the operator — Armason reviews and challenges every material commercial term as part of every enterprise engagement, ensuring that contracts reflect the buyer’s actual requirements and risk appetite rather than operator defaults.
How Armason Sources Enterprise Colocation
Armason’s approach to enterprise colocation procurement starts with a structured requirement definition that captures every variable relevant to operator selection and commercial negotiation. Power requirement and redundancy specification. Density and cooling needs. Connectivity requirements including carrier preferences, cloud on-ramp needs, and internet exchange access. Compliance and certification requirements. Geographic constraints across primary and secondary locations. Timeline. And commercial parameters including contract length flexibility and budget envelope.
This brief is used to engage a targeted set of operators with genuine enterprise colocation capability and availability matching the requirement. We do not broadcast to the market. We engage the operators most likely to deliver, manage the proposal process to ensure responses are directly comparable, and provide clear evaluation across technical fit, commercial terms, and delivery credibility.
Where multiple operators are credible, we create structured competitive tension that consistently delivers better commercial terms than direct single-operator negotiation. Where the preferred location cannot deliver the requirement on the required timeline, we provide honest alternatives — adjacent markets, phased approaches, or build-to-suit structures where operators commit to delivering to specification on a forward timeline.
We work with enterprise buyers across all sectors — AI and HPC, enterprise compute, healthcare and regulated, and technology and SaaS. Minimum engagement is 1MW. All enquiries are handled confidentially.
Enterprise Colocation by Location
London — Europe’s largest colocation market and the primary location for latency-sensitive enterprise workloads. Power is the principal constraint. New wholesale capacity on a twelve to eighteen month timeline is scarce — pre-let opportunities and adjacent sub-markets represent the most realistic near-term options.
Manchester — the strongest UK alternative to London for enterprise colocation. Active operator build programmes, better grid accessibility, and a 30 to 50 percent cost advantage versus equivalent London capacity make Manchester the default recommendation for buyers without a hard London requirement.
Frankfurt — Europe’s primary enterprise colocation hub for continental deployments. DE-CIX access, GDPR compliance maturity, and the deepest financial services ecosystem in continental Europe.
Amsterdam — AMS-IX access and strong EU data residency credentials, though power constraints from the Dutch moratorium require careful navigation.
Dublin — hyperscaler cloud on-ramp access unmatched in Europe. The default location for cloud-connected enterprise architectures requiring EU data residency.
