Design and strategy for Umbraco websites
Need more than an Umbraco build or support? Our in-house design and strategy team also covers UX, creative direction and brand identity. Whether you're rethinking how users move through your website or refreshing your brand alongside a rebuild, it's all handled by the same team. That keeps your design, brand and Umbraco build working together from day one.
From first build to long-term care, here's how we support your Umbraco website at every stage:

Our creative team sets the visual direction for your website, so every page feels consistent, distinctive and true to your brand.

Our processes are built for multiple stakeholders and fast-moving requirements, with clear communication and planning that makes room for change.

FAQs
Is Umbraco free to use?
Yes, the Umbraco core CMS is completely open-source, meaning there are zero ongoing software licensing fees. You only pay for our bespoke design, development, and integration services.
Why choose an Umbraco Gold partner?
As a certified Gold Partner, our team includes 3 Umbraco Certified Experts and 2 Umbraco Certified Professionals. You gain guaranteed best-practice coding, direct support from Umbraco HQ, and a future-proof website built to scale safely.
Can you upgrade our older Umbraco website?
Yes. We routinely migrate older setups (like Umbraco 7, 8 or 13) to Umbraco 17, the current long-term support (LTS) release, seamlessly transferring your content, assets, and data with minimal downtime and zero data loss.
Is Umbraco secure for enterprise brands?
Absolutely. Built on Microsoft’s robust .NET framework, Umbraco features rigorous built-in protection against common security vulnerabilities, making it a top choice for global brands and public sector organisations.
Do you provide ongoing Umbraco support?
Yes, we view clients as long-term partners. We offer flexible, dedicated support packages covering routine security patching, performance optimisation, and feature updates to keep your site running flawlessly.
How long does an Umbraco build take?
The timeline depends on complexity, custom integrations, and data migration needs. Once we scope your specific goals, we provide a transparent, milestone-based timeline so you know exactly what to expect.
How much does an Umbraco website cost?
Umbraco itself is free, so you only pay for design, development and any integrations. Every project is scoped individually, so we don't publish set prices. The main things that shape the cost are the size of your website, how many templates and integrations you need and how much content needs migrating. Upgrades and support plans are usually smaller, clearly defined pieces of work, while a full new build is a bigger investment. After an initial conversation, we'll give you a clear, itemised quote and can phase the work to fit your budget.
Can you migrate us to Umbraco from WordPress?
Yes. We manage WordPress to Umbraco migrations from start to finish, including content migration, URL redirects and SEO, so you keep your search visibility. We also set Umbraco up around how your team works, so editors feel at home from day one.
Do you work with Umbraco clients in London?
Yes. We work with organisations across London and are around an hour from the city, so we regularly meet clients in person when it helps a project. London teams get senior Umbraco expertise without the overheads of a large city agency.
Can you support large-scale or complex Umbraco projects?
Yes. We regularly deliver Umbraco projects with multisite structures, custom functionality, third-party integrations and large volumes of content. We manage complexity through clear planning and realistic delivery phases, keeping your website maintainable as it grows.
