Simon Antony

An Umbraco Silver Partner agency based in Llandudno, North Wales, Simon Antony is led by Simon Steed, a specialist with more than 20 years of .NET development experience. Operating as a small team, the agency works with businesses and other agencies across the UK and internationally, focusing on mid-market organisations that want the flexibility of Umbraco's open-source CMS without the licensing overhead associated with enterprise platforms. As one of fewer than 150 Umbraco Silver Partners worldwide, it has direct access to Umbraco HQ technical support and early access to new platform releases, and it also takes on white-label development work on behalf of other agencies. Services cover custom Umbraco development built on ASP.NET Core and C#, including greenfield builds, integrations and API-driven architectures, alongside Umbraco website design, content management, audits, performance optimisation, and SEO and content strategy work specific to the platform. Additional offerings include Umbraco migrations and upgrades, legacy site rescues, infrastructure and DevOps support, and ongoing retainer-based support and maintenance. A current fixed-price service covers upgrading sites from Umbraco 13 to 17, priced at £8,999 plus VAT, positioned ahead of the end of Umbraco 13 security support in December 2026, with the upgrade delivered over roughly 21 days without downtime and followed by 30 days of post-launch cover. The broader service model emphasises architectural clarity, clean code and long-term maintainability across new builds, migrations and site rescues, rather than quick fixes.
