Hosting should be the thing you never think about. Here's what that takes.
Auto-balanced cloud
We left shared hosting behind in 2009. Your site uses the resources of an entire platform, and load is rebalanced in real time as traffic moves.
Our own CDN, free
Pages are edge-cached close to your visitors on our own network. Fewer hops means faster loads, less energy per request, and no separate Cloudflare bill.
30-day timeline backups
Every account, every day. Roll back to any of the last 30 days in two clicks, or ask us and we'll do it for you.
Migration, handled
We move your files, databases and email from cPanel, Plesk, WordPress, Fasthosts or Heart Internet. No downtime. No charge.
UK support
Staffed by people who have run this platform for years. Ticket, live chat or phone — you'll speak to someone who can actually fix it.
The price stays the price
No introductory rate that triples on renewal. No countdown timers. What you pay in month one is what you pay in year five.
The green credential, rendered as data.
No leaf icons. No stock photos of wind turbines. Every number below is independently verifiable, and each one carries its source.
Every figure here links to its source. The Ecologi ledger is public. The ISO certificate is downloadable. If a claim can't be evidenced, it isn't on this page.

We don't ask customers for star ratings. Here's what's actually running on the platform right now — and how long it takes us to actually fix things.
Figures as of July 2026, taken from the platform. We publish the count, not a rating — a number you can check beats a star you can buy. 37,324 customers have hosted with us since 1996.

It really depends on what you need. We offer a range of hosting packages from £3.50 per month for Startups and Personal Users, all the way to Corporate clients Dedicated Servers. We don't use introductory rates that jump on renewal, and we don't run countdown timers. Pricing is in pounds sterling, excluding VAT.

Power Usage Effectiveness measures how much of a data centre's energy actually reaches the servers, rather than being lost to cooling and overhead. A PUE of 1.0 would be perfect. Ours is 1.2, meaning roughly 83% of the energy drawn reaches the compute. The industry average sits around 1.5. Yes.
