What is Simon Antony?
Simon Antony is an Umbraco Silver Partner agency based in North Wales, led by Simon Steed — an Umbraco specialist with over 20 years of hands-on .NET development experience. We deliver bespoke Umbraco CMS solutions for businesses and agencies across the UK and internationally.
As one of fewer than 100 Umbraco Silver Partners worldwide, we have direct access to Umbraco HQ technical support and early access to new platform releases. Our work spans custom builds, white-label agency partnerships, legacy site rescues, performance optimisation, and ongoing retainer support.
According to BuiltWith, Umbraco powers over 730,000 live websites globally, including organisations like Microsoft, the NHS, and Carlsberg. We specialise in helping mid-market businesses and agencies take advantage of Umbraco's open-source flexibility without the overhead of enterprise CMS licensing. Based in Llandudno, we work remotely with clients across the UK and beyond.
As an Umbraco Silver Partner, we deliver specialist development support for businesses and agencies looking for clean, scalable, and well-architected Umbraco solutions.
From white label builds and performance audits to new site launches and legacy rescue work, we bring the technical clarity and hands-on support you need – without the agency overhead or jargon.
Whether you need help with a new site build, a legacy rescue, or white label development support, we’ve got the experience to handle it – with none of the agency overhead. We’re based in North Wales and work with clients across the world.
Our expertise covers custom Umbraco builds, performance audits, integrations, templating, architecture guidance, and ongoing support. We focus on long-term results, not quick fixes, and bring technical clarity to every project.
OUR SERVICES
Why choose an Umbraco specialist over a generalist agency?
Umbraco is a developer-first CMS built on ASP.NET Core and C#. Unlike WordPress or Drupal, it has no plugin dependency, every feature is custom-coded, which means you need a developer who understands the platform deeply, not a generalist who treats it like another CMS.
According to G2's 2025 peer review data, Umbraco consistently outscores WordPress, Sitecore, and Drupal for ease of customisation and developer satisfaction. But those advantages only materialise when the implementation is done properly. A poorly architected Umbraco site is harder to fix than a poorly built WordPress site because there are no plugins to fall back on.
That's why working with an Umbraco Certified Master matters. We bring architectural clarity, clean code, and long-term maintainability to every project, whether it's a new build, a migration, or a rescue of an existing site that's gone off the rails.

Our latest news
What should you know about Umbraco in 2026?
The CMS landscape is shifting. AI-powered search engines now drive over 527% more referral traffic year-on-year according to SparkToro, and Google AI Overviews reach 1.5 billion users monthly. Traditional SEO alone is no longer enough, websites need to be optimised for both human visitors and AI systems.
At the same time, the Umbraco platform continues to mature. Version 17 LTS, released in late 2025, brings .NET 10 support, improved content delivery APIs, and better performance out of the box. For organisations still running Umbraco 8 or earlier, end-of-life support deadlines are past, you need to be looking at upgrading.
Our articles cover practical guidance on Umbraco upgrades, CMS migration decisions, AI readiness, and web performance, written from direct project experience, not theory.

TESTIMONIALS
What do clients say about working with Simon Antony?
We've worked with organisations ranging from the British Red Cross and the Scottish NHS to specialist recruitment firms and marine science bodies. Our client relationships typically span multiple years. Most of our retainer clients have been with us for over three years, which we believe says more about our work than any sales pitch.
Client feedback consistently highlights three things: we communicate clearly without jargon, we deliver on time, and we're honest about what a project actually needs rather than upselling unnecessary work. As a small, senior-led team, every project gets direct access to the architect who built it, there's no junior handoff after the sales call.
We're happy to provide references and case studies on request. You can also see examples of our work in our portfolio.

Andrew Tedder
Head of Customer Services - Yes Telecom (Vodafone company)
I worked with Simon for 18 Months between Aug 2006 and Feb 2008 in this time I found Simon to be a friendly and approachable person. Simon had high standards and expected his colleagues to meet or exceed these standards. He was also especially good at asking the right questions so he was in possession of all the facts. Armed with these facts he was able to consistently push projects past the finishing post.
