About UmbHost

UmbHost has been hosting sites since 2009. We started as TerrabitHost, became Terrabit.Host, and in 2021 rebranded as UmbHost - by then the customer base was almost entirely Umbraco, and the name needed to say so.

The rebrand was led by Aaron Sadler, an Umbraco MVP and Certified Master who's still at the helm today. From the beginning the proposition has been the same: deep specialism in one CMS, run by people who contribute to it.

In 2024, we took on the hosting and development of Wholething's customers when illness forced them to close. The brief was simple: keep their clients online, supported, and unaffected by the transition. Most of those customers are still with us today.

In 2025, UmbHost joined the Growcreate Group, bringing together specialist Umbraco hosting and the Umbraco development expertise of our sister agency under one roof. Customers now have access to both sides of the platform from one team.

In January 2026 we launched GreenStack, our modern containerised hosting platform, alongside UmbPanel, the proprietary control panel we built specifically for Umbraco. GreenStack is the platform of the next decade for us, multi-datacentre, load-balanced, zero-downtime deployments on Umbraco 17+, all on infrastructure powered by 100% renewable energy.

Legacy Windows hosting still serves Umbraco v4–v12 customers and will continue to do so. From the oldest installs to the newest, we're the only hosting company built to run every version of Umbraco there is.

UmbHost is run by people who work with Umbraco every day, not generalists who happened to add Umbraco support to a wider hosting business. The team includes Umbraco Certified Masters and an Umbraco MVP, with sixteen years in web infrastructure and ten-plus working specifically with Umbraco.

Every ticket is handled by someone who works with the platform daily. No first-line triage. No generalist helpdesk. The person who replies to your support request is the same kind of person who built the infrastructure underneath it.

UmbHost is also part of the Growcreate Group, which means access to a wider pool of Umbraco development expertise and engineering capacity when a project needs more than hosting alone.

Open source isn't just what we host on, it's how we work. Umbraco itself is open source. So are most of the tools we build on top of it. Where we can contribute back, we do, through code (UmbCheckout, uCaptcha and other Umbraco packages), through sponsorship (we sponsor Skrift Magazine and individual Umbraco package authors), and through free hosting for community sites that wouldn't otherwise have a home.

Sustainability isn't a marketing line, it's an operational decision. Every server we run is on 100% renewable energy. We're partnered with Ecologi to plant trees and offset carbon for every customer at no cost to them. We chose data centre partners specifically because of their renewable commitments, not despite them. The Petersfield Awards 2023 runner-up for Green Business of the Year and the SME News 2025 Best Eco-Friendly Hosting & Development Provider award reflect that, but the operational decisions came first.

Specialism isn't a niche, it's a commitment. We've stayed Umbraco-focused for over a decade because being deep beats being broad. We don't take on customers we can't serve well, and we'd rather refer a project elsewhere than half-deliver it.
