Which UK cloud provider is best? 5 providers compared

If you’re looking for a reliable cloud solution, the UK market offers a range of es­tab­lished providers spe­cial­ising in secure document col­lab­or­a­tion, backup, managed storage and cloud in­fra­struc­ture. Our com­par­is­on covers five UK cloud providers suited to different business re­quire­ments.

What are the benefits of cloud storage services?

Cloud storage allows or­gan­isa­tions to store data on remote servers and access it over the internet instead of relying solely on local computers, servers or external drives. The services available vary con­sid­er­ably: Ideagen Col­lab­or­a­tion Portal focuses on secure document col­lab­or­a­tion, Redstor spe­cial­ises in backup and recovery, Ex­po­nen­tial-e and iomart provide managed business cloud services, and Civo offers cloud in­fra­struc­ture and object storage.

One of the main benefits of using a cloud is that au­thor­ised users can access data from different locations and devices. Depending on the provider, or­gan­isa­tions may be able to share documents, manage access per­mis­sions, col­lab­or­ate in con­trolled work­spaces or expand their storage capacity without pur­chas­ing and main­tain­ing ad­di­tion­al hardware.

Cloud services can also support data pro­tec­tion and business con­tinu­ity. Redstor provides cloud-based backup and recovery, while Ex­po­nen­tial-e and iomart offer storage, backup and disaster-recovery services for business en­vir­on­ments. These services can help or­gan­isa­tions restore data following ac­ci­dent­al deletion, hardware failure, cy­ber­at­tacks or other dis­rup­tions. However, file syn­chron­isa­tion and document sharing should not be treated as complete sub­sti­tutes for a properly con­figured backup strategy.

To improve cloud security, or­gan­isa­tions should use strong au­then­tic­a­tion, carefully manage access per­mis­sions and check which en­cryp­tion, mon­it­or­ing and recovery features are included. Ideagen Col­lab­or­a­tion Portal, for example, provides con­trolled work­spaces for sharing documents with employees, clients and external partners, while Civo offers cloud services for technical workloads, including UK sovereign cloud options.

Security, privacy and data-handling ar­range­ments differ between UK cloud providers. Or­gan­isa­tions that value greater data sov­er­eignty should therefore check where their data and backup copies are stored and processed, which laws and con­trac­tu­al terms apply and what control they retain over access, deletion and in­ter­na­tion­al transfers. A provider’s UK headquar­ters do not ne­ces­sar­ily mean that every service auto­mat­ic­ally stores all customer data in the UK.

Ideagen Col­lab­or­a­tion Portal

Ideagen Col­lab­or­a­tion Portal (formerly known as Ideagen Huddle) is a secure cloud col­lab­or­a­tion platform designed primarily for busi­nesses, gov­ern­ment bodies and other or­gan­isa­tions that need to share and manage documents with internal and external users. Rather than func­tion­ing as a general-purpose personal drive, it provides con­trolled online work­spaces for document col­lec­tion, review, approval and col­lab­or­a­tion.

Col­lab­or­a­tion Portal is par­tic­u­larly suitable for or­gan­isa­tions that work with clients, suppliers or public-sector partners and require greater control over how documents are accessed and managed. Its key features include:

• Secure work­spaces for employees, clients and external partners
• Document sharing, review and approval
• File version control and change tracking
• Tasks, comments and file requests

Redstor

Redstor is a UK cloud backup and recovery brand, now part of Cy­ber­Sentriq, the cy­ber­se­cur­ity and data pro­tec­tion platform formed in 2025 through Redstor’s merger with TitanHQ. It continues to serve busi­nesses, IT teams and managed service providers. Its platform is designed to protect data held across servers, endpoints, cloud platforms and software-as-a-service ap­plic­a­tions.

Unlike con­ven­tion­al UK cloud storage designed mainly for everyday file syn­chron­isa­tion, Redstor focuses on pro­tect­ing business data and restoring it following ac­ci­dent­al deletion, hardware failure, cy­ber­at­tacks or other incidents. Its main features include:

• Automated cloud backup for servers and endpoints
• Backup and recovery for Microsoft 365 ap­plic­a­tions, including OneDrive, Share­Point, Teams and Exchange

Costs: Redstor provides tailored packages for or­gan­isa­tions and managed service providers. Costs depend on the volume and type of data protected, the required retention period and the selected recovery features.

Ex­po­nen­tial-e

Ex­po­nen­tial-e is a UK tech­no­logy provider offering managed con­nectiv­ity, cloud, security and com­mu­nic­a­tions services. Its cloud storage solutions are aimed at or­gan­isa­tions that require scalable capacity, con­trolled data locations and support for business-critical workloads.

Ex­po­nen­tial-e is par­tic­u­larly suited to busi­nesses looking for a managed cloud in the UK rather than a consumer file-storage service. Its storage portfolio covers different workload types and can be combined with con­nectiv­ity, backup, security and disaster-recovery services. Key features include:

• Cloud object storage for large volumes of un­struc­tured data
• File and block storage for different business ap­plic­a­tions

• Solutions for or­gan­isa­tions with data-sov­er­eignty and com­pli­ance re­quire­ments

Costs: Ex­po­nen­tial-e provides cus­tom­ised business solutions. Pricing depends on the storage type, capacity, per­form­ance, con­nectiv­ity and managed services required.

iomart

iomart is a UK-based managed cloud and data centre provider. It offers cloud in­fra­struc­ture, storage, backup, cyber recovery and disaster-recovery services for busi­nesses that want expert support managing their data and IT en­vir­on­ments.

Rather than providing a con­ven­tion­al personal cloud drive, iomart focuses on managed business in­fra­struc­ture. It operates a na­tion­wide network of wholly owned data centres and supports or­gan­isa­tions using private, public and hybrid cloud en­vir­on­ments. Its services and features include:

Costs: iomart creates tailored solutions based on each or­gan­isa­tion’s in­fra­struc­ture, storage and support re­quire­ments. Costs vary according to capacity, data pro­tec­tion, recovery ob­ject­ives and the level of man­age­ment required.

Civo

Civo is a UK-headquartered cloud platform designed primarily for de­velopers, tech­no­logy teams and busi­nesses running cloud-native ap­plic­a­tions. Its services include compute, Kuber­netes, databases and scalable object storage.

Civo is not a con­ven­tion­al file-sync platform for private users. Its UK cloud storage is aimed at technical workloads and ap­plic­a­tions that need scalable storage accessed through an S3-com­pat­ible interface. Civo also offers a UK Sovereign Cloud for or­gan­isa­tions that require in­fra­struc­ture hosted and operated within the United Kingdom. Its main features include:

• UK Sovereign Cloud services hosted and operated ex­clus­ively within the UK

Costs: Civo uses usage-based pricing for its cloud in­fra­struc­ture and storage services. Costs depend on the selected region, storage capacity, computing resources and ad­di­tion­al platform services.

Bonus solution

The providers above are headquartered in the United Kingdom. However, UK customers are not limited to UK-based services. IONOS HiDrive is included as a bonus option because it is available in the UK while offering an al­tern­at­ive from a Germany-based company, with ISO 27001-compliant European data centres, encrypted data transfer and optional end-to-end en­cryp­tion.

IONOS HiDrive

IONOS HiDrive cloud storage offers a privacy-focused solution for cloud storage. Your data is stored in ISO 27001–certified data centres and fully complies with data pro­tec­tion re­quire­ments to ensure the highest level of data pro­tec­tion for your cloud.

• Automatic backups and syn­chron­isa­tion of data
• Sharing features for easy col­lab­or­a­tion in teams
• TLS/SSL-secured transfer (AES-256)
• Optional end-to-end en­cryp­tion for ad­di­tion­al security (included in the Pro package)

Costs: Prices vary depending on the selected package and the storage space included

Cloud storage plus online backups for optimal security

Whichever cloud storage service you choose, storing your files in the cloud alone is not enough to provide complete pro­tec­tion. Regular backups are also essential because they allow you to restore data after hardware failures, malware attacks, ac­ci­dent­al deletion or other un­ex­pec­ted problems.

For greater re­li­ab­il­ity, your cloud service should include an automatic backup feature. This ensures that copies of your data are created regularly without requiring manual action, making recovery easier when something goes wrong.

A strong backup strategy should also follow the 3-2-1 backup rule, a widely re­cog­nised approach to pro­tect­ing data:

• Keep 3 copies of your data: the original and two separate backups.
• Store them on 2 different types of storage media, such as a local hard drive and cloud storage, to reduce the risk of a single failure affecting every copy.
• Keep 1 copy off-site, for example in the cloud or at another physical location, so your data remains protected if a local incident occurs.

The 3-2-1 rule provides multiple copies across different storage systems and locations, helping protect your data against hardware failures, cy­ber­at­tacks, ac­ci­dent­al loss and natural disasters.
