Finding the best cloud storage for business UK in 2026 is one of the most practical decisions a small or medium business owner can make. Whether you are replacing a local file server, enabling remote working, or simply trying to stop employees emailing documents back and forth, the right cloud storage platform will save time, reduce risk, and keep your team on the same page from any device or location.
The UK market has several strong contenders, each with different pricing models, integration strengths, and compliance considerations. This guide covers the platforms most relevant to UK SMBs in 2026: Microsoft OneDrive for Business, SharePoint Online, Dropbox Business, Google Drive for Work (via Google Workspace), and Box for Business. We have also included a brief look at a self-hosted alternative for businesses that prefer to keep data on-premises. Read on for a full breakdown, honest pros and cons, and a clear recommendation at the end.
What to Look For in Business Cloud Storage
Before comparing platforms, it helps to know what actually matters for a business context. Storage capacity per user is an obvious starting point, but equally important are collaboration features (real-time co-editing, version history, folder sharing), security controls (admin permissions, audit logs, two-factor authentication), UK or EU data residency for GDPR compliance, integration with the tools your team already uses, and total cost of ownership including per-user licensing. Mobile app quality, offline access, and the ease of migrating existing files are also worth weighing up before you commit.
1. Microsoft OneDrive for Business
Microsoft OneDrive for Business is the default cloud storage layer bundled into Microsoft 365 subscriptions, making it the most commonly adopted platform among UK SMBs almost by default. Each user gets 1 TB of personal cloud storage as standard on most plans, with that storage syncing seamlessly with File Explorer on Windows and Finder on Mac. Files are accessible from any browser or via the mobile app, and the sync client is mature, reliable, and tightly woven into the Windows operating system in a way no third-party tool can quite match.
For a business already paying for Microsoft 365 Business Basic, Business Standard, or Business Premium, OneDrive is effectively included at no extra cost. This makes it extremely compelling from a value perspective. Version history goes back up to 180 days on paid plans, and features like Personal Vault (an extra layer of PIN or biometric protection for sensitive files) and ransomware recovery add meaningful security layers. If you want a deeper look at whether the wider Microsoft 365 bundle is worth it for your business, our guide on Microsoft 365 for Small Business UK: Is It Worth It? covers the full picture.
The main limitation is that OneDrive for Business is a personal drive rather than a true team document library. It works best when combined with SharePoint (covered next) for shared team content. On its own, it is excellent for per-user storage, but it is not designed as a centralised shared drive in the same way Dropbox or Google Drive are.
| Plan | Storage Per User | Approx. Price (Per User/Month) | Key Feature |
|---|---|---|---|
| Microsoft 365 Business Basic | 1 TB | From around £4.90 | OneDrive + Teams + web apps |
| Microsoft 365 Business Standard | 1 TB | From around £9.90 | Full desktop Office apps included |
| Microsoft 365 Business Premium | 1 TB | From around £18.60 | Advanced security and Intune MDM |
2. Microsoft SharePoint Online
SharePoint Online is Microsoft’s team-focused document management and collaboration platform, and it sits alongside OneDrive as part of the Microsoft 365 ecosystem. Where OneDrive handles personal storage, SharePoint is designed for shared document libraries, team sites, and departmental content. In 2026, it remains the most feature-rich option for businesses that need granular permission controls, document workflows, and a structured intranet-style environment for organising files by project or department.
Each Microsoft 365 tenant gets a pool of SharePoint storage (typically 1 TB plus 10 GB per licensed user), and this shared storage is accessible to all team members with appropriate permissions. SharePoint integrates directly with Microsoft Teams, meaning files shared in a Teams channel are actually stored in SharePoint behind the scenes. This makes the two tools effectively inseparable for most Microsoft-first businesses. Version control, check-in and check-out functionality, and metadata tagging make SharePoint a serious choice for businesses with compliance or document management requirements.
The honest downside is complexity. SharePoint has a reputation for being difficult to set up and maintain without IT support, and casual users often find the interface less intuitive than Dropbox or Google Drive. For a small team without an IT administrator, OneDrive alone may be sufficient. For growing businesses with 20 or more users who need proper document governance, SharePoint is hard to beat within the Microsoft ecosystem.
| Feature | Detail |
|---|---|
| Shared storage (per tenant) | 1 TB + 10 GB per licensed user |
| Version history | Up to 500 versions per file |
| Included in | All Microsoft 365 Business plans |
| Best for | Team document libraries, intranets, compliance |
| Admin complexity | Medium to high |
3. Dropbox Business
Dropbox Business remains one of the most polished and user-friendly cloud storage platforms available in 2026. It has built its reputation on a sync engine that is exceptionally fast and reliable, a clean cross-platform experience across Windows, Mac, iOS, and Android, and an interface that genuinely requires very little training for new users. For UK businesses that want something that just works without extensive IT configuration, Dropbox Business is a strong contender.
The Business and Business Plus tiers offer shared team folders, granular admin controls, account transfer tools (useful when staff leave), and integrations with Slack, Zoom, Microsoft 365, and Google Workspace. Dropbox Paper, the built-in collaborative document tool, is included but rarely replaces a full office suite. Extended version history (up to 180 days on Business, one year on Business Plus) is a valuable safety net for accidental deletions or ransomware incidents. Dropbox also stores data in EU data centres, which is relevant for UK businesses assessing post-Brexit data residency requirements.
The main drawback is cost. Dropbox Business starts at around £12 per user per month (when billed annually), which is noticeably more expensive than comparable Microsoft or Google plans once you factor in what those bundles include. If your team already uses Microsoft 365 or Google Workspace, you are essentially paying for a second platform. Where Dropbox earns its premium is in the quality of the sync experience and cross-platform consistency, particularly for teams that mix Windows and Mac devices.
| Plan | Storage | Approx. Price (Per User/Month) | Version History |
|---|---|---|---|
| Dropbox Business | Unlimited (fair use) | From around £12 | 180 days |
| Dropbox Business Plus | Unlimited (fair use) | From around £20 | 1 year |
| Dropbox Enterprise | Unlimited | Custom pricing | Custom |
4. Google Drive for Work (Google Workspace)
Google Drive for Work is the cloud storage component of Google Workspace, Google’s suite of business productivity tools. In 2026, Google Workspace remains a serious rival to Microsoft 365, particularly for businesses that are comfortable working primarily in a browser and value real-time collaboration above almost everything else. Google Docs, Sheets, and Slides offer genuinely excellent multi-user editing, and files stored in Drive are immediately accessible from any device with a Google account.
The Business Starter plan gives each user 30 GB of pooled storage, which is modest by modern standards. The Business Standard plan steps up to 2 TB of pooled storage per user and adds recorded Meet calls stored directly to Drive, which is a practical feature for distributed teams. Google’s AI-powered search across Drive is genuinely impressive and makes finding files significantly faster than browsing folder structures. Shared drives (formerly called Team Drives) allow content to be owned by the organisation rather than individual users, solving a common problem when staff leave. For a full breakdown of what the platform includes, our guide to Google Workspace: What Is It? is a useful starting point.
Google stores data in its global infrastructure, and UK and EU data residency options are available from Business Standard upwards via data region policies. One consideration for UK businesses is that Google Workspace relies heavily on web-based apps, which may not suit teams accustomed to full desktop Office applications. If you are weighing up the two major ecosystems directly, our Microsoft 365 vs Google Workspace comparison covers the key differences in detail.
| Plan | Storage Per User | Approx. Price (Per User/Month) | Key Feature |
|---|---|---|---|
| Business Starter | 30 GB pooled | From around £5.20 | Gmail + Drive + Docs |
| Business Standard | 2 TB pooled | From around £10.40 | Meet recordings, larger storage |
| Business Plus | 5 TB pooled | From around £15.60 | Advanced audit and eDiscovery |
5. Box for Business
Box is a cloud content management platform that sits in a slightly different space to the consumer-origin tools above. It was built specifically for enterprise and business use, with compliance, security, and workflow features front and centre from day one. For UK businesses in regulated industries such as legal, financial services, or healthcare, Box offers a compelling set of controls including granular access permissions, data loss prevention, detailed audit trails, and compliance certifications including ISO 27001, SOC 2, and GDPR data processing agreements.
Box Business plans offer unlimited storage, robust external sharing controls, custom branding for shared links, and integrations with over 1,500 third-party applications including Salesforce, Slack, Microsoft 365, and Google Workspace. Box Sign, included in higher tiers, allows legally binding e-signatures directly within the platform, which is a practical addition for contract-heavy businesses. The interface is clean and relatively intuitive, though it lacks the deep operating system integration that OneDrive offers on Windows.
Box is not the cheapest option on this list. Business plans start at around £13 per user per month, and the feature set most suited to regulated businesses sits in the Business Plus or Enterprise tiers. For a typical five-person marketing agency or retail business, Box may be more platform than you need. For a 30-person accountancy firm or legal practice where compliance is non-negotiable, it is well worth evaluating.
| Plan | Storage | Approx. Price (Per User/Month) | Key Feature |
|---|---|---|---|
| Business | Unlimited | From around £13 | Full collaboration and admin tools |
| Business Plus | Unlimited | From around £20 | Advanced workflows and metadata |
| Enterprise | Unlimited | Custom pricing | DLP, compliance, custom security |
6. Sync.com for Business
Sync.com is a privacy-focused cloud storage provider that often flies under the radar compared to the major platforms but deserves consideration for UK SMBs with strong data privacy requirements. It offers end-to-end encryption by default, meaning even Sync.com itself cannot access your files. For businesses handling sensitive client data, legal documents, or financial records, this zero-knowledge architecture provides a meaningful additional layer of protection beyond what Microsoft or Google offer in their standard configurations.
Business plans include team folder sharing, granular user permissions, remote device wipe, version history, and audit logs. Storage starts at 1 TB per user and scales upward. Pricing is competitive, typically coming in below Dropbox Business for comparable storage. The trade-off is a more limited integration ecosystem and a collaboration experience that is functional rather than exceptional. Sync.com does not offer anything equivalent to real-time co-editing in Google Docs or Microsoft 365, so it works best as a secure file repository rather than an active collaboration hub.
| Plan | Storage Per User | Approx. Price (Per User/Month) | Key Feature |
|---|---|---|---|
| Teams Standard | 1 TB | From around £5 | End-to-end encryption |
| Teams Plus | 4 TB | From around £8 | Extended version history |
| Teams Advanced | 10 TB | From around £12 | Full admin and compliance tools |
7. Self-Hosted NAS as a Cloud Alternative
For businesses that prefer to keep their data entirely on-premises rather than trusting a third-party cloud provider, a Network Attached Storage (NAS) device with remote access capabilities offers an alternative worth considering. Synology and QNAP are the leading NAS vendors in the UK market, and their business-grade units can be configured to behave very much like a private cloud, with web and mobile access, sync clients for desktops, shared folder permissions, and even Microsoft 365 or Google Drive integration for hybrid workflows.
The upfront hardware cost is higher than a monthly subscription, but for businesses with large data volumes or data sovereignty concerns, the total cost of ownership over three to five years can be lower than paying per-user cloud fees. The tradeoff is that you are responsible for hardware maintenance, backups, and physical security. Remote access also depends on your internet connection quality and uptime. This option suits businesses with an IT-literate owner or a part-time IT manager rather than those wanting a fully managed service. For more on NAS options, see our guide to the Best NAS for Small Business.

Our Recommendation
For the majority of UK small and medium businesses in 2026, the best cloud storage for business UK comes down to which productivity suite you are already using. If you are on Microsoft 365, lean into OneDrive for Business and SharePoint Online. You are already paying for both, they are deeply integrated with the tools your team uses daily, and the combination of personal OneDrive storage plus shared SharePoint libraries covers almost every business storage scenario. If you are on Google Workspace, Google Drive for Work is equally well-suited and offers excellent value at the Business Standard tier. For businesses without an existing suite, or those mixing Mac and Windows devices and wanting the simplest possible shared folder experience, Dropbox Business justifies its higher price point through sheer reliability and ease of use. If compliance is your primary concern, Box or Sync.com deserve serious evaluation. And if you want to keep your data entirely in-house, a quality NAS device remains a viable and cost-effective alternative.

Frequently Asked Questions
What is the best cloud storage for small business in the UK in 2026?
For most UK small businesses, the best option is whichever platform aligns with their existing productivity suite. OneDrive for Business is ideal if you are already on Microsoft 365, while Google Drive for Work suits Google Workspace users. Dropbox Business is the best standalone choice for teams wanting a simple, reliable shared folder experience across mixed devices. All three offer strong UK data residency options and GDPR-compliant data processing agreements.
Is OneDrive good enough for business use?
Yes, OneDrive for Business is genuinely well-suited to most small and medium business needs, particularly when combined with SharePoint for shared team content. It provides 1 TB of storage per user, strong security features, seamless Windows integration, and is included in all Microsoft 365 Business plans. For teams already invested in the Microsoft ecosystem, it offers outstanding value and reliability.
Does UK GDPR affect which cloud storage I should choose?
UK GDPR requires that any personal data you store about clients, employees, or prospects is handled securely and that you understand where that data is stored. All major business cloud platforms offer data processing agreements (DPAs) that help satisfy GDPR requirements. Microsoft, Google, and Box all offer UK or EU data residency options on business plans. Sync.com’s end-to-end encryption means your data is unreadable even to the provider, which adds another layer of protection for sensitive data.
What is the difference between OneDrive and SharePoint for business?
OneDrive for Business is personal cloud storage assigned to each individual user, similar to a private drive in the cloud. SharePoint is a shared document management platform designed for team and departmental content, with libraries that the whole organisation or specific groups can access. In practice, most Microsoft 365 businesses use both: OneDrive for personal and in-progress files, and SharePoint for team-shared documents, project folders, and company-wide resources.
Is Dropbox Business worth the cost compared to OneDrive or Google Drive?
Dropbox Business is more expensive than OneDrive or Google Drive on a like-for-like basis, but it earns its premium through superior sync reliability, an exceptionally clean cross-platform experience, and consistent performance across Windows and Mac devices. If your team is already paying for Microsoft 365 or Google Workspace, adding Dropbox is likely unnecessary. However, for teams without an existing suite or those frustrated by sync issues with other platforms, Dropbox Business remains one of the most dependable options available.
