Your London Site is Losing Customers While You're Waiting on Dev
If you're a London founder watching competitors ship while your agency misses deadlines, we close your launch gap in 6 weeks -- fixed price, no retainer drift.
We build fast websites and web apps for London businesses. Next.js, headless CMS, and modern infrastructure -- delivered on time.
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.
What is holding your current website back?
Common gaps we find in nearly every audit.
What Your Website Could Look Like
Custom-designed for your industry. No templates. No stock photos.
How We Build This Right
Every safeguard, built in from Day 1.
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.
What We Build
Purpose-built features for your industry.
Deploy production-ready React and Next.js builds with TypeScript -- type-safe, maintainable, and ready for your next feature sprint
Your site scores above 90 on Lighthouse within two weeks of launch -- Google rewards fast sites with better rankings and your bounce rate drops immediately
Integrate headless CMS that your marketing team edits without Slack requests -- structured content, version history, preview modes built in
Your marketing team publishes new landing pages, updates pricing, and schedules blog posts without waiting on developer capacity or paying hourly rates
Connect Stripe or Shopify Storefront APIs with custom checkout logic that matches your actual business rules, not a template's assumptions
Your checkout converts 18–22% higher when payment flows load in under 1.2 seconds and match your brand, not a generic Stripe embed
Build API bridges between your CRM, booking platform, payment processor, and analytics stack so data flows without manual exports
Your sales team pulls live data from HubSpot, sends it to your dashboard, and triggers Slack alerts without building custom Zapier chains that break every update
Migrate off WordPress or legacy monoliths to JAMstack architecture without losing organic rankings, redirects, or six years of blog posts
Your site keeps its Domain Authority, backlink profile, and organic traffic after migration -- we map every URL, test every redirect, and monitor rankings for 90 days post-launch
Run monthly Core Web Vitals audits and ship incremental performance fixes so your site stays faster than the competitor who launched last quarter
Your hosting bill drops from £400/month to £40/month on Vercel or Netlify, and you stop paying retainers for plugin updates that should be automated
Built on a Modern, Secure Stack
London-specific delivery
London market context
London's web development scene splits between legacy enterprise systems in the Square Mile and fast-moving startups clustered around Old Street and Shoreditch. We see a lot of fintech, proptech, and healthtech clients navigating FCA compliance, GDPR data residency, and UK accessibility regulations. The market expects production-grade infrastructure--not prototypes--with AWS eu-west-2 deployments, Stripe UK integration, and proper Companies House API work. Competition is fierce, but most agencies still push WordPress or expensive custom stacks. Clients here want Next.js performance, Vercel edge caching, and developer handoff they can actually maintain.
How we work with London
Social Animal's HQ studio is in London, so you'll work directly with Aryan and the core team in person when it makes sense--kickoffs, design reviews, UAT sessions. Day-to-day runs through Slack and Linear, with Loom recordings for async updates. We're in GMT, which means real-time collaboration during your working hours. No timezone gymnastics, no 9pm calls. For London clients, we'll meet at your office or ours for strategy sessions, then shift to remote delivery with weekly check-ins. You get the speed of a remote-first team with the trust of a local partner.
Clerkenwell Physio Collective
healthcare / physiotherapyMulti-location physio clinic with a Wix site that couldn't handle online booking or patient forms. Built them a Next.js 14 app with Supabase backend, integrated with their existing Cliniko practice management system via API. Headless CMS (Sanity) for the clinical team to update treatment pages and therapist bios. Stripe for membership payments, GDPR-compliant form handling, and a custom booking flow that syncs with Cliniko availability in real-time. Deployed on Vercel with ISR for near-instant page loads.
Lighthouse mobile score went from 34 to 97. Booking conversion rate improved by 40% in the first two months, and their admin team saved roughly 6 hours per week previously spent on manual appointment entry. The Sanity CMS meant their content editor could update treatment pages without developer support.

London projects typically range £12k–£45k depending on scope. A brochure site with headless CMS and basic integrations starts around £12k–£18k. E-commerce or SaaS product builds with Supabase backend, Stripe billing, and custom dashboards run £25k–£45k+. Fintech or regulated industries add compliance overhead. We quote in GBP, invoice through our UK entity, and don't charge VAT to VAT-registered businesses. Most clients budget for a 6–12 week build, then optional retainer (£2k–£5k/month) for ongoing feature work and maintenance.
