What Actually Ships When You Work With a Modern London Agency

Your site goes live in six weeks with a production-ready Next.js build, integrated headless CMS your team can edit without opening a support ticket, and Core Web Vitals scores above 90. You're not waiting on contractors in three time zones or paying £800/day for scope creep. Your London agency commits to fixed-fee delivery: £5,000 gets you a marketing site with Sanity CMS, Stripe checkout, and full mobile responsiveness. £12,000 gets you a custom web app with API integrations and user authentication. Every project includes staging environment, Git version control, and two weeks of post-launch support. No retainers for basic edits. No surprise invoices when your developer takes holiday. Your business runs on infrastructure that costs £40/month to host, not £400. That gap between promise and deploy? It closes the day you commit to modern tooling and a team that actually finishes what it starts.

Wo Projekte scheitern

Your site scores below 50 on Google Lighthouse Poor Core Web Vitals hurt your organic rankings and cost you qualified London traffic every single day.
Agencies keep missing deadlines and blowing budgets Delayed launches mean delayed revenue — every week without a working site is money left on the table.
Your WordPress site is slow and constantly needs security patches Plugin vulnerabilities expose customer data, and a single breach can destroy brand trust in a competitive London market.
You can't update content without bothering a developer Marketing bottlenecks slow your campaigns and kill the agility you need to compete in the UK market.
Your site looks fine on desktop but breaks on mobile Over 60% of London users browse on mobile — a broken experience sends them straight to a competitor.
You're paying monthly retainers for basic hosting and maintenance Thousands in recurring costs for infrastructure that should run at a fraction of the price with modern serverless architecture.

Compliance

GDPR-Compliant by Default

Every site we build includes proper cookie consent, data handling workflows, and privacy-first analytics. UK and EU data protection is built in from day one — not bolted on afterward.

Performance-First Architecture

We build on Next.js with edge deployment, so your London users get sub-second load times. Static generation and ISR keep pages fast without sacrificing dynamic content.

Accessibility Standards (WCAG 2.1)

Semantic HTML, keyboard navigation, screen reader support, and contrast ratios that meet AA standards. Accessible sites convert better and reduce legal risk.

SEO Technical Foundation

Structured data, proper heading hierarchy, canonical tags, and server-rendered content that search engines can actually crawl. No client-side rendering black holes.

Headless CMS Integration

Content editors get a clean, intuitive interface. Developers get full control over the frontend. Sanity, Contentful, or Strapi — we pick the right tool for your team.

Analytics & Conversion Tracking

Privacy-respecting analytics with real conversion attribution. Know exactly what's working so you can put budget into the right channels for your London audience.

Häufige Fragen

How much does web development cost in London?

Custom web development in London typically ranges from £5,000 for a brochure site to £25,000+ for complex web applications. We work on fixed-fee pricing so you know the total cost before we start. No hourly billing, no scope creep surprises. Your quote covers design, development, CMS setup, and 30 days of post-launch support.

How long does it take to build a website in London?

Most projects ship in 6–8 weeks from signed proposal to live deployment. Simple marketing sites can launch in 4 weeks. Complex web apps with custom integrations and e-commerce typically take 10–12 weeks. We give you a detailed timeline during discovery and hit our deadlines consistently.

Do you only work with London-based businesses?

No. We work with businesses across the UK and internationally. Being London-based means we're available for in-person meetings when it makes sense, and we operate in GMT/BST for straightforward scheduling with European and US East Coast clients. Most collaboration happens asynchronously via shared project boards.

Why do you use Next.js instead of WordPress?

Next.js delivers faster page loads, better security, and stronger SEO performance compared to WordPress. There are no plugin vulnerabilities to patch, no database to maintain, and pages load in under a second on edge infrastructure. We pair Next.js with a headless CMS so content editing stays simple and intuitive for non-technical teams.

Will my new site rank well on Google in the UK?

We build every site with technical SEO built in — server-rendered HTML, structured data, proper heading hierarchy, fast Core Web Vitals, and clean URL architecture. These are the foundations Google rewards. We don't guarantee rankings, but we do guarantee the technical infrastructure gives you the strongest possible starting position for UK search.

Do you offer ongoing maintenance after launch?

Every project includes 30 days of post-launch support covering bug fixes, performance monitoring, and content assistance. After that, we offer monthly retainers for ongoing development, security updates, and performance optimisation. Most London clients opt for our lightweight maintenance plan to keep their site current and fast.
