The average UK web design agency still builds on WordPress, charges premium fees for a business website, takes 8–12 weeks to deliver, and hands over a site that scores 60–80 on Google Lighthouse. FactoryJet builds every website on Next.js 15 and Tailwind CSS 4 — the same technology stack behind Stripe, Vercel, and Linear — delivering sites that score 90+ on Lighthouse, load in under two seconds, at a fixed price scoped to your build.
We work with businesses across the entire United Kingdom, from London startups to Leeds financial firms to Edinburgh tech companies to Bristol aerospace innovators. Whether you need a bespoke website design for a professional services firm, a custom website development project with React and headless CMS architecture, a JAMstack development build for maximum performance, or an affordable web design package for a growing small business, our web development agency delivers at a quality and speed that traditional traditional agencies simply cannot match.
Every website we build is mobile-responsive, SEO-optimised from day one, and structured for AI search visibility — meaning your site is built not just for Google rankings, but for ChatGPT citations, Perplexity references, and Google AI Overview mentions. We also specialise in industry-vertical web design, with experience building high-converting sites for law firms, restaurants, healthcare organisations, real estate businesses, and professional services.
How much does a website cost in the UK? Traditional agencies tend to charge premium fees for both standard and custom builds. FactoryJet works on a fixed-price model scoped to your project, with the main drivers being page count, design depth, and any integrations you need. Every project is quoted up front after a free discovery call, so you know the full cost before work starts. Our pricing is competitive because our AI-augmented development workflow eliminates the inefficiencies that inflate traditional agency costs. And for UK business owners, web design is a legitimate business expense claimable against your corporation tax or income tax with HMRC, reducing the effective cost.
