Overview — 01

Social Animal is a London web development agency building production-grade Next.js and Astro sites on fixed-price contracts from £8K. We scope before we quote, ship in weeks not quarters, and you meet the engineer doing the work on day one.

No hourly billing means no incentive to drag timelines. No offshore handoffs means your brand decisions don't get lost in a Slack thread at 3am.

Every build targets Lighthouse 90+ because Google's Core Web Vitals have been a ranking signal since 2021, and a slow site on WordPress is quietly bleeding your visibility every day. Your project gets a guaranteed timeline, a single point of contact, and a team you can meet in person when the details matter.

What A Fixed-Price London Web Build Actually Includes -- And Why It Stops Scope Creep

Your brief lands with a London team. Within 48 hours you're talking to the developer who'll build your site -- not a project manager, not a sales team, the person writing your code. We scope it, price it fixed, and ship it on Next.js or Astro with SEO architecture baked in from commit one.

The gap — 02

What is holding your current website back?

Common gaps we find in nearly every audit.

Here's the thing about London web agencies -- they'll quote you £120,000 for a site that should cost £30,000
Risk: We've seen it dozens of times. Bloated account management teams, junior developers doing the actual work, and hourly billing that somehow expands to fill whatever budget you walked in with. Nobody's accountable for the final number because everyone's just logging time. And the worst part? You often can't tell until the invoice lands. The web development market in London is genuinely opaque, and agencies know it. So they pad. They add "discovery phases" and "stakeholder alignment workshops" that produce a 40-page PDF nobody reads. We scope every build ourselves and know exactly what things cost to do properly -- which is why we work fixed-price. No hourly rates, no scope creep surprises, no account manager in the middle inflating everything they touch. Just a real number, upfront, before we start.
Your current agency built on WordPress and your Lighthouse score is sitting at 45
Risk: That's not a minor issue. Google's been using Core Web Vitals as a ranking signal since 2021, and a score that low is actively costing you search visibility every single day. Plus, visitors notice. A slow site -- especially on mobile -- kills trust faster than bad copy ever could. And the frustrating bit is it's usually fixable. It's just that most WordPress shops don't have the incentive to fix it.
You want someone you can actually sit down with
Risk: Not a Slack thread at 2am, not a project manager in a different timezone interpreting your brief for a developer you've never spoken to. Brand decisions are nuanced. UX calls require real conversation. And honestly, those details get mangled in offshore handoffs -- the brief says one thing, the build delivers another, and you're three revisions deep before anyone admits there's a miscommunication.

Safeguards — 03

How we build this right

Every safeguard, built in from Day 1.

Fixed Price, Written Contract

Every engagement is governed by a plain-English contract with a locked price and defined deliverables. If scope does not change, the price does not change.

GDPR-Ready by Default

Cookie consent, data handling, and third-party script loading are configured correctly on every build we ship, so you are not creating compliance debt before launch.

Performance Benchmarked at Handoff

We supply a Lighthouse and Core Web Vitals report at delivery. If the scores do not meet the agreed thresholds, we fix it before we close the project.

Scope — 04

Working with London clients — 05

London-specific delivery

London market context

London's web development market is shaped by a dense fintech corridor around Old Street and Shoreditch, heavy regulatory requirements (FCA compliance for finance, GDPR for data handling), and a startup ecosystem that expects production-grade infrastructure from day one. We see two buyer profiles: well-funded seed/Series A startups moving fast with VC runway, and established SMEs migrating off legacy WordPress or Drupal to modern stacks. Competition is fierce--lots of agencies promising 'digital transformation' but shipping bloated React apps that score 30 on Lighthouse mobile. Clients here increasingly expect headless CMS, serverless deployment, and sub-200ms TTFB across Europe.

How we work with London

We're based in London, so London clients get proper in-person access--kickoff workshops, face-to-face sprint reviews, whiteboard sessions when architecture needs hashing out. Day-to-day we run Slack for comms, Linear for task tracking, Loom for async design reviews. Most projects involve 2-3 in-person sessions across discovery and launch, with the rest over video. Timezone is GMT, same as you, so no 9pm calls.

Budget context for London projects

London web dev projects typically range £18k–£65k depending on scope. A brochure site with headless CMS and basic SEO setup sits around £22k–£28k. SaaS migration (Bubble/Webflow to Next.js + Supabase) with auth, billing, and API integrations usually lands £45k–£65k. Startups with VC funding move faster and care more about scalability than cost; bootstrapped SMEs want fixed-price with phased delivery. We quote in GBP, invoice through a UK Ltd, VAT-registered. Most London clients expect Net 30 payment terms and detailed milestone breakdowns.

Process — 06

Our development process

From discovery to launch. Quality at every step.

01

Paid Discovery and Scoping

1 week

We meet with your team to map goals, user flows, content structure, and third-party integrations. The output is a documented scope, a fixed quote, and a start date. This session costs £950 and is credited against the project if you proceed.

02

Design in the Browser

1-2 weeks

We produce component-level designs as working code on a staging URL, not layered Figma files that never survive contact with development. You review and approve in the environment your users will actually experience.

03

Build and Integration Sprints

2-4 weeks

Development runs in two-week sprints with a deployed preview at the end of each cycle. CMS setup, API integrations, analytics, and performance optimisation are completed within the sprint plan, not tacked on afterwards.

04

QA, Handoff, and Go-Live

1 week

We run cross-browser and device testing, deliver the Core Web Vitals report, and walk your team through the CMS and deployment pipeline before handing over repository access. Post-launch support is available on a retained or per-request basis.

Questions — 08

Frequently asked questions

We're a London-based team, and we meet in person for kickoffs, sprint reviews, or to hash out technical decisions face-to-face--at your office or a space that suits. We don't run a walk-in studio or hot-desk setup, so in-person sessions are scheduled around project milestones. Day to day, delivery runs remotely through Slack, Linear, and Loom.
Most builds take 6–10 weeks from signed contract to production launch. Discovery and architecture usually need 1–2 weeks (faster if you've got detailed specs and designs ready). Development sprints run in two-week blocks. We don't do 'MVP in 3 weeks' promises--that's how you end up with technical debt and a 40 Lighthouse score. If you need something live for a funding round or event, tell us the date upfront and we'll scope honestly about what's achievable.
Yes, but we're engineers, not compliance consultants. We've shipped platforms for FCA-regulated clients where we handle the technical requirements: audit logging, data residency in EU regions, encryption at rest, SOC 2-ready infrastructure. You'll need your own legal/compliance advisor to sign off on regulatory obligations. We'll build to the technical spec they provide--Supabase RLS for data isolation, server-side session handling, secure API design--but we don't write your compliance documentation.
All the time. About half our London clients are non-technical founders who've prototyped in Webflow or Bubble and need a production rebuild. We'll translate your business logic into technical architecture, explain tradeoffs in plain English, and avoid jargon-heavy proposals. You don't need to know what 'SSR' or 'edge functions' mean--we'll recommend what fits your growth plan and explain why. In-person kickoffs help a lot here; easier to whiteboard user flows than explain over Zoom.
We're London-based and plugged into the city's startup ecosystem, from accelerator cohorts to bootstrapped founders who skipped that route. We get how VC-backed timelines work (tight deadlines around Demo Day or next funding round) versus bootstrap pace (phased launches, MVP then iterate). We're also realistic about what 'scalable' actually means at seed stage--you don't need Kubernetes when you've got 200 users.
We're based in London -- so yes, we can actually meet. Whether that's a proper discovery workshop, a coffee to talk through a brief, or ongoing collaboration as your product evolves, face-to-face is always an option. We work with businesses across London regularly, but we've also delivered projects across the UK and internationally. Location's never been a blocker.
We build frontends in Next.js and Astro, backends on Supabase and Payload CMS, and we deploy on Vercel. Every project ships with a Lighthouse score above 90, structured data baked in, and Core Web Vitals that actually pass. That's not a bonus -- it's the baseline. And we don't build on WordPress. Full stop.
Fixed-price, always. Marketing sites start at £8,000 and enterprise platforms go to £80,000 and beyond -- but whatever the number is, you'll know it before we start. No hourly billing, no "it depends on what comes up." You get a fixed price, a fixed timeline, and a site built to rank. That's pretty much the opposite of how most London agencies operate, which is honestly why clients come to us after a bad experience elsewhere.
Yes -- and most clients do. Once a build wraps up, we offer retained support packages from £1,500/month. That covers hosting management, performance monitoring, content updates, and ongoing SEO maintenance. So the site doesn't just launch well -- it stays that way. The real kicker is that we already know your codebase inside out, so there's no expensive handover to a third party who has to figure out how everything works.
