Els Labs
Web Development

Websites and web apps that perform, convert and scale.

We design and build custom websites and web applications using Next.js and React — optimised for speed, accessibility and search engines. From marketing sites to complex platforms, every project is engineered to grow with your business.

What we deliver

Built for performance, scale and clarity.

Next.js & React expertise

We build every project on Next.js and React — the same stack trusted by Vercel, the BBC and countless high-growth startups — so you get server-side rendering, static generation and edge caching out of the box.

Performance-first architecture

Every site ships with a sub-second Largest Contentful Paint target. We optimise images, fonts, JavaScript bundles and third-party scripts to keep Core Web Vitals firmly in the green.

SEO built into the foundation

Semantic HTML, structured data, canonical URLs and automated sitemap generation are wired in from day one — not bolted on as an afterthought. Your pages are built to rank.

Accessible & standards-compliant

We follow WCAG 2.2 AA guidelines throughout the build process. Keyboard navigation, screen-reader support and colour-contrast checks are part of every pull request review.

CMS & headless integration

Whether you prefer Sanity, Contentful, Strapi or a custom headless CMS, we integrate content management seamlessly so your team can publish without touching code.

Responsive across every device

From mobile-first layouts to wide-screen dashboards, we test across real devices and browsers to guarantee a polished experience at every breakpoint.

How we build it

A structured approach, every time.

01

Discovery & requirements

We run a focused discovery sprint to map your goals, audience and technical constraints. The output is a prioritised feature backlog and a clear project brief signed off by all stakeholders.

02

Design & prototyping

Interactive Figma prototypes let you click through every key journey before a line of production code is written. We iterate quickly, incorporating your feedback in real time.

03

Development & testing

We work in two-week sprints with fortnightly demos. Automated tests, code reviews and CI/CD pipelines ensure that every deployment is stable, secure and fully auditable.

04

Launch & continuous improvement

After go-live we monitor performance, fix any edge-case issues and hand over comprehensive documentation. Optional retainer plans keep your site updated, secure and performing at its best.

FAQ

Common questions.

How much does web development cost in the UK?+

A typical custom website built with Next.js ranges from £8,000 for a marketing site to £50,000+ for a complex web application. The final cost depends on the number of unique page templates, integrations, content migration needs and ongoing support requirements. We provide a fixed-price quote after a free discovery call so there are no surprises.

How long does a website take to build?+

Most marketing websites are delivered within 6–10 weeks from kick-off. Larger web applications with user authentication, payment processing or third-party integrations typically take 12–20 weeks. We agree a timeline during discovery and provide weekly progress updates throughout the build.

Do you build WordPress websites?+

We specialise in Next.js and React because they deliver superior performance, security and scalability compared to traditional WordPress. However, if your team already relies on WordPress for content editing, we can integrate it as a headless CMS behind a modern Next.js front end — giving you the best of both worlds.

Will my website be optimised for search engines?+

Absolutely. Every site we build includes semantic HTML, server-rendered pages, automated meta tags, structured data markup and a dynamically generated sitemap. We also run Lighthouse audits before launch to ensure Core Web Vitals are in the green, which directly impacts your Google ranking.

Can you redesign my existing website without losing SEO rankings?+

Yes. We map all existing URLs and set up 301 redirects, transfer structured data and preserve meta information so search engines recognise the new site as a continuation of the old one. We also monitor Google Search Console post-launch to catch and fix any indexing issues quickly.

What technologies do you use for web development?+

Our core stack is Next.js, React and TypeScript, deployed on Vercel or AWS. For styling we use Tailwind CSS, and for data we integrate with PostgreSQL, Supabase or headless CMS platforms. Every project includes automated testing with Vitest and Playwright, plus CI/CD via GitHub Actions.
