Web design & development agency

Most website design and development projects are completed within approximately 16 weeks, although timelines vary depending on build complexity, scope and the speed of feedback and content delivery. Clear milestones are agreed from the start, with regular updates throughout the process so you always know where the project stands and what comes next.

Each stage of the process includes clear opportunities for feedback and approval, with agreed review points before the project progresses. Designs are shared openly for discussion and refinement, and development only begins once sign-off is in place, helping ensure changes are made collaboratively and at the right stage.

Once your website goes live, we remain on hand to support it as it becomes part of your everyday operations. From post-launch aftercare to optional ongoing website support and maintenance, we help ensure the site remains secure, reliable and well maintained as your business grows and changes.

The cost of a website depends on the scale and complexity of the build, with requirements varying significantly between simple brochure sites and more advanced eCommerce platforms. Elements such as integrations, content requirements, template volume and technical detail all affect the overall scope. Instead of fixed pricing tiers, we create bespoke proposals that clearly outline what is included and how the investment aligns with your business objectives.

We use industry-leading tools throughout the design and development process to ensure clarity, collaboration and efficiency. Website designs are produced in Figma, making it easy to review layouts and interactions before development begins, while builds are delivered using our proprietary SDK and a carefully chosen technical stack tailored to each project.

A custom WordPress website uses a traditional CMS where content and presentation are closely connected, making it ideal for businesses that want control and easy day-to-day editing for their marketing teams. A headless website separates the backend from the frontend, enabling faster performance, the use of modern technologies such as React or Next.js, and greater flexibility when integrating with third-party tools and platforms.

Yes, every website we build is developed with SEO in mind from day one. This includes fast loading times, mobile-first design, clean semantic code, schema markup and properly optimised metadata. If you are migrating from another platform, we manage redirects carefully and preserve existing rankings to protect visibility throughout the transition.

It depends on your goals and how your current site was built. If your site has a strong foundation, we can often make performance, design and usability improvements without starting from scratch. But if it’s holding back your growth, whether due to bloated code, poor structure or limited flexibility, investing in a brand new website may be more cost-effective in the long run.

Yes, mobile-first design is a core part of how we build websites. Every site is tested across multiple devices and browsers to ensure fast load times, usability and consistency, reflecting how users now browse, research and convert online.

Not at all. While we’re based on the South Coast and have a strong local presence in Portsmouth, Southampton, Winchester, Chichester, Fareham, Basingstoke, Guildford and across Hampshire, we partner with brands nationwide. From Bournemouth to Bristol, Manchester to Edinburgh, we deliver fast, UX-led and secure websites for clients across the UK.

We take a strategic, user-first approach. Our process starts with discovery and planning, where we explore your goals, customers and target audience. From there we develop wireframes and design concepts that align with your branding services and business needs. We then build clean, high-performing websites that support long-term growth.

Once your site is live, we can support you through our ongoing packages that include technical maintenance, performance checks, UX/CRO improvements and SEO audits. We offer monthly retainers or ad hoc support depending on your needs, all with the same team who built the site staying involved.

With nearly two decades of experience building websites here in the UK, our approach is shaped by a deep understanding of what businesses need to grow online. All work is carried out by our in-house team of designers, developers and SEO specialists, ensuring quality and continuity from start to finish. The result is websites that perform technically, align with audience expectations and drive measurable results through stronger visibility and conversion.

We’re happy to scope projects of different sizes and suggest phased approaches where possible. If a full custom build isn’t viable right now, we can offer scaled-down solutions or roadmap support to help you move forward strategically.

Integrity, creativity and client focus sit at the heart of how we work at boxChilli. We take a transparent approach, focus on solving real problems and shape our recommendations around evidence and commercial priorities. Rather than treating websites in isolation, our work supports your wider digital strategy and the services that drive day-to-day business performance.
