Web applications built for speed, search and scale.

Web application development is the process of designing and building software that runs in a web browser, from corporate websites with a CMS to complex multi-user platforms. Unlike static websites, web applications have user authentication, dynamic data, API integrations and interactive interfaces. We design them to be fast, secure and able to scale.

A corporate website costs £3,000–£12,000. A full web application with authentication, a database and integrations costs £15,000–£60,000+. The main cost drivers are the number of user roles, integrations, custom design work and content migration. We provide a written quote, with scope and exclusions agreed up front, after a free discovery call.

A corporate website typically takes 2–4 weeks. A web application with user authentication and integrations typically takes 6–16 weeks. We work in two-week sprints, so you see progress and working software continuously rather than at the end.

If visitors mainly read, compare and contact you, you need a website. If they need to log in, place orders, manage bookings, see their own data or work with others, you need a web application. Many businesses need both: a fast marketing site in front of a portal or app. We will recommend the smallest option that does the job.

Ask to see live sites and check their load speed yourself, confirm technical SEO is part of the build rather than an extra, insist on a written quote with clear exclusions and code ownership set out in the contract, and read verified reviews on independent platforms.

Yes. Every site we build is mobile-first by design and tested across device sizes. We target 90+ Google Lighthouse mobile scores and optimise for Core Web Vitals, because most visitors arrive on a phone.

We use headless CMS platforms such as Contentful, Sanity or Strapi for performance and flexibility, or WordPress — standard or as a headless backend — when your team already knows it. We choose based on who will edit content and how often, not on our preference.

No one can honestly promise rankings, and we don’t. What we do is build the technical foundations search engines look for: structured data, semantic HTML, Core Web Vitals optimisation, canonical URLs, hreflang and XML sitemaps. Rankings then depend on your content, competition and links, which we can advise on.

Yes. We redesign and rebuild existing websites while preserving your SEO equity: mapping every old URL to a redirect, migrating content and metadata, and monitoring Search Console after launch — planned to give you a faster, better-converting site while protecting the traffic you already have.

Yes — custom ecommerce platforms, Shopify and WooCommerce builds, and headless commerce architectures. We also build B2B wholesale portals, product configurators and custom checkout flows with Stripe and multi-currency support.

You do. On full payment, as set out in your contract, you receive the full source code, CMS and hosting access and documentation, with accounts in your company’s name. There is no licence fee, and any developer can maintain the site after us.

Support after launch is available through optional monthly maintenance retainers agreed with you, covering bug fixes, security updates, performance monitoring and content changes — or we can provide a documented handover to your own team.
