Challenges we solve
Your data has to stay in the UK
Regulation, customer contracts, or public-sector rules mean your workloads can't sit in a data centre on the other side of the world. You need certainty about where your data resides.
Compliance keeps getting harder
Auditors want evidence, not assurances. Proving data residency, access control, and encryption across a sprawling public-cloud estate takes time you don't have.
Hyperscaler bills are unpredictable
Consumption pricing is hard to forecast, and the bill rarely matches the budget. You want the flexibility of cloud with costs you can actually plan around.
You don't want to hand over control
Self-service matters, but so does knowing a UK team is watching the platform around the clock. You need both: the freedom to build and the safety net of expert support.
What is Claranet Sovereign Cloud?
Claranet Sovereign Cloud is an Infrastructure-as-a-Service (IaaS) platform built and operated in the UK. You get the agility of public cloud, with the assurance that your data stays within UK borders and within reach of a team you can pick up the phone to. "Sovereign" here means three specific things: your data is hosted, processed and backed up entirely within UK data centres; the platform is operated by a UK-based Claranet team, not a subsidiary of an overseas parent company; and support, patching and administration are all carried out from the UK. This is different from simply choosing a "UK region" on a public hyperscale cloud, where the underlying provider may still be headquartered overseas - a distinction that matters for organisations that need to evidence data residency to auditors, regulators or public-sector procurement teams.
You configure compute, storage, networking, and backup to suit your workloads, then manage it all yourself through a dedicated tenant portal. Spin up virtual machines from a catalogue of operating system templates or bring your own. When you need a steer, our Competitive Edge consultants work with you through the Discover, Analyse, Architect, and Mobilise phases to design the right solution for where your business is heading.
Choose a shared platform for standard workloads, or a dedicated cluster where licensing, performance, or security demands call for it. Either way, the infrastructure sits in secure, ISO-compliant UK data centres with encryption at rest, resilient power, and round-the-clock monitoring as standard.

Frequently Asked Questions
-
A sovereign cloud is cloud infrastructure that is hosted, operated and supported entirely within one country's borders, by a provider based in that country — giving organisations a clear, evidenceable answer about where their data lives and who can access it.
-
A public cloud UK region stores data in the UK, but the underlying provider may still be headquartered overseas and subject to that country's laws. Claranet Sovereign Cloud is hosted, operated and supported by a UK-based team, on UK-owned infrastructure.
-
Yes - it's used by organisations where data residency isn't optional, including UK police forces managing case data and digital evidence, and healthcare providers hosting Electronic Patient Records and medical imaging under UK/EU data sovereignty requirements. See how UK police forces and healthcare providers use it to evidence data residency to auditors and regulators.
-
Public cloud (e.g. AWS, Azure UK regions): fast to scale and consumption-priced, but the underlying provider may be headquartered overseas - meaning data stored in a UK region can, in some circumstances, still be subject to foreign law. Private cloud: dedicated infrastructure, often on-premises or in a single data centre, giving strong control but less flexibility and typically higher fixed cost. Sovereign cloud (Claranet): the self-service flexibility of public cloud, delivered on infrastructure that is UK-hosted, UK-operated, and UK-supported end to end - built for organisations that need to evidence data residency, not just claim it.
-
Entirely within Claranet's UK, ISO 27001-certified data centres. Data is not processed or backed up outside the UK as part of this service.
-
Claranet Sovereign Cloud runs entirely in UK data centres, operated by Claranet's UK business — your data is not hosted or managed by an overseas parent company, and administration, support and patching are all carried out by UK-based teams. That's a straightforward answer to a question that's become harder to give confidently on public hyperscale platforms, where the underlying provider may be subject to overseas legislation even when data is stored in a UK region. This isn't a claim that Claranet's platform is exempt from all legal process — it's a statement of operational and jurisdictional control that most public cloud "UK region" options cannot make.
