Umbraco

Looking to upgrade from Umbraco 13?

Umbraco 13 ends on 14 December 2026. We make the move to 17 LTS straightforward.

Umbraco 13 reaches end-of-life on 14 December 2026. After that date it receives no security patches, no bug fixes and no support. The practical deadline is earlier still: Umbraco 13 runs on .NET 8, which Microsoft stops supporting on 10 November 2026, so we plan to the November date.

The recommended destination is Umbraco 17 LTS, released in November 2025 and supported until November 2028. For most sites already on Umbraco 13 this is a direct path, and the editor experience in 17 is an incremental change rather than a wholesale relearn.

Nimbus moves large content sets across with far less manual effort, which shortens the timeline and cuts the error rate. DXA gives the build a tested starting point. On the Marshalls replatform, Nimbus migrated 763 content items in an eight-week window with zero errors and no loss of SEO, and reduced migration costs by 28%.

Proven across regulated and complex sectors

We've built Umbraco sites across financial services, healthcare, manufacturing and professional services, for organisations including Asda Money, Morgan Advanced Materials, NHS Blood and Transplant, Simpson Millar and Turner & Townsend. Marshalls runs on a complex Umbraco Cloud implementation we deliver, combining custom search, commerce and personalisation.

Asda Money, in financial services, came to us for a build where compliance and governance mattered as much as performance; the work delivered a 109% increase in non-brand organic sessions alongside gains in form submissions and product-page engagement. The Marshalls replatform drove a 92% increase in B2C sample requests. Over 15 years we have delivered more than 30 Umbraco enterprise websites.

Sustainability that is measured, not asserted

Our Head of Sustainability, Neil Clark, sits on Umbraco's Community Sustainability Team, one of a small number of agency representatives helping shape how the platform measures and reduces the carbon footprint of Umbraco websites. We co-created the open-source umbraco.community.sustainability package, now used across the Umbraco community to estimate page-level emissions.

Lower-carbon websites are lighter, which means they load faster, rank better and cost less to run. As part of B Corp certified MSQ, we provide emissions data alongside the build, so for organisations with Net Zero commitments or ESG reporting obligations, sustainability is something you can measure rather than something we simply claim.

Active in the Umbraco community

We co-run UmbLeeds, the Umbraco Leeds meetup, which has brought the community together on the first Thursday of most months for more than ten years, across in-person, hybrid and social events. We have spoken at Codegarden, Umbraco's annual conference, and we contribute packages and improvements back to the platform.

Our team includes Umbraco MVP Jonathan Wood, who leads our technical thinking, alongside strategic subject-matter experts Ibrar Hussain and John Prior who shape platform strategy across complex engagements. This kind of continuous involvement keeps our teams close to where Umbraco is heading, which is the difference between implementing the platform and helping shape it.

AI-ready Umbraco, without vendor lock-in

We position every Umbraco build for the AI era through the platform's "Bring Your Own AI" approach. Rather than locking clients into embedded features, Umbraco's Model Context Protocol makes the CMS accessible to any AI client, so organisations keep control of their AI strategy as it evolves. We advise on both the MCP platform approach for technically mature teams and marketplace AI packages for immediate editor value, matched to each client's needs. Our Umbraco MVP, Jonathan Wood, and Umbraco subject matter experts lead our technical thinking here.
