The verdict
20i is a UK-based cloud hosting company offering reseller-friendly infrastructure, StackCP control panel, and a rare pay-monthly billing model with no lock-in contracts, popular among UK developers and agencies.
The full picture
20i is a British host founded in 2011 by the team behind Stack Group, which also runs the long-established reseller platform Heart Internet and the wholesale brand TSOHost. It operates its own cloud infrastructure from United Kingdom data centres, and its distinguishing feature is that almost every plan is effectively unlimited: unlimited websites, unlimited bandwidth, unlimited email, unlimited free SSL, and no fixed disk quota on many tiers.
The second distinguishing feature is the reseller platform. 20i is one of the most capable white-label hosting platforms in Europe, with a well-built control panel, automated billing integration, per-client resource management, free migrations of entire portfolios and a genuinely good API. A large number of United Kingdom web agencies run their client hosting on it.
The platform includes a proprietary caching layer, StackCache, a free global CDN, malware scanning and a one-click WordPress toolkit. Support is United Kingdom based and available around the clock. The limitations are geographic: the infrastructure is British, so audiences elsewhere depend on the CDN.

Performance in practice
Good for a United Kingdom and European audience. StackCache plus the free global CDN produces fast cached responses, and the platform runs on modern hardware in British data centres rather than resold capacity. Because plans have no hard disk quota and unlimited bandwidth, there is no artificial ceiling on a growing site — the limits are CPU and memory, applied per account.

Moving a site in
Free migrations including bulk transfers of entire reseller portfolios, handled by the 20i team. This is a genuine strength — moving a hundred client sites is a supported, routine operation rather than a project.
The trade-off
In its favour
- Flexible pay-monthly billing
- Strong reseller feature set
- UK data residency
Worth knowing
- Brand less known outside UK
- Learning curve for StackCP
Who should look elsewhere
- Audiences far outside Europe wanting a local origin
- Buyers who require cPanel specifically
- Enterprise workloads needing formal account management
- Anyone wanting email and hosting bundled with a large brand name

Yes, its pay-monthly plans have no long-term lock-in contracts.
The bottom line
The best reseller and multi-site platform in the United Kingdom, and a very good value for anyone hosting more than a couple of sites. Unlimited everything, free CDN, free SSL, free bulk migrations and honest pricing. Look elsewhere only if you need cPanel or a non-European origin.
