How scoping works

How website projects get scoped in the UK

Website development costs in the UK vary wildly because no two projects are the same. A brochure site with eight pages, existing copy and an existing brand sits at one end. A custom build with new branding, written-from-scratch copy and programmatic landing pages sits at the other. Most agencies hide this by giving you a single number; we'd rather be transparent about the variables that actually drive cost.

The five biggest cost drivers are platform (Headless versus WordPress versus a like-for-like migration), page count (how many unique templates and content pages you need), content production (whether we write the copy or you supply it), brand assets (whether we build the brand foundation or apply your existing guidelines), and integrations (forms, CRMs, third-party data, analytics).

Everything else - performance targets, SEO setup, schema markup, analytics, training and handover - is included as standard on every Aeonix build. That keeps the pricing conversation honest: you're paying for the bits that change project to project, not for the foundations that should come with any modern build.

Cost drivers

What pushes a website price up

  • Higher page count. Each unique template adds copywriting, design and build time.
  • Programmatic pages. Templated landing pages auto-generated at scale (location pages, integration pages, comparison pages).
  • New brand work. Logo system, colour, type, components - building the foundation from scratch.
  • Copywriting. Research, interviews, writing and editing for every page rather than supplying your own.
  • Third-party integrations. HubSpot, Salesforce, bespoke APIs, custom CRMs, advanced analytics setups.
  • Multilingual setup. Separate content trees, locale routing, translation workflow.
  • Complex information architecture. Deep navigation, faceted filtering, member areas, gated content.
  • Multiple stakeholder rounds. Bigger teams, more sign-offs, more revisions.
Cost reducers

What brings the price down

  • Like-for-like migration. Keeping the existing design and copy, just moving platform. Starts at £4,500.
  • Existing brand guidelines. Skip the brand foundation step, we apply what you have.
  • You supply the copy. Saves around £150 per page versus us writing it.
  • Simple page structure. A handful of core templates instead of bespoke layouts per section.
  • Single decision-maker. Fewer rounds, faster sign-off, lower agency time.
  • Clear content and IA upfront. Discovery moves faster when you already know what every page needs to do.
  • Phased delivery. Launch the core site first, add programmatic pages or extra templates in a follow-up phase.
Always included

  • Technical SEO setup (sitemap, robots, canonicals, redirects)
  • GA4 and Search Console configuration
  • Up to 2 forms with lead capture
  • One round of revisions per page
  • 30 days post-launch support

Migrations

What migrations specifically cover

Migration projects are like-for-like rebuilds: same design, same copy, same URLs, new platform. Cheaper because we're not rethinking anything - we're translating what works onto a faster stack.

  • Page-for-page rebuild on Astro + Keystatic or Sanity
  • Existing copy migrated, not rewritten
  • Existing design translated, not redesigned
  • Full redirect map from old URLs to new URLs
  • SEO preservation (meta tags, schema, canonicals)
  • Aeonix AEO foundations layered in (llms.txt, upgraded schema, Core Web Vitals)
  • GA4 and Search Console migration
Out of scope

What we don't include (and where we refer out)

Being honest about what we don't do matters as much as being clear about what we do. The list below is quoted separately or referred to specialists who do it better than we would.

  • Ecommerce functionality (we refer to specialists)
  • Content migration beyond standard scope
  • Custom illustration or photography
  • Third-party integrations (HubSpot, Salesforce, bespoke APIs)
  • Multilingual setup
  • Additional forms beyond two
  • Ongoing maintenance retainer (separate retainer matrix)
  • Landing pages or microsites (custom scope, case by case)
Common questions

Frequently asked questions

How much does a website cost in the UK?

Most UK business websites land somewhere between £5,000 and £25,000 depending on platform, page count, copywriting and brand work. A like-for-like migration starts at £4,500. A custom Headless build with brand foundations, copy and programmatic pages can push past £20,000. The calculator above gives you a real range based on your inputs in under a minute.

What's the difference between a Headless build and WordPress?

Headless (our default) decouples the front end from the CMS. You get sub-second loads, perfect Core Web Vitals and a clean, editor-friendly back end. WordPress is the right call when you specifically need it - heavy plugin ecosystem, existing team familiarity, or a hard requirement from your stack. Both come with the same Aeonix AEO foundations baked in.

When is a migration the right option versus a new build?

Choose a migration when your existing design, copy and information architecture are working. We rebuild page-for-page on a faster platform, preserve every URL with redirects, and layer in AEO foundations. If you want a redesign, new copy, restructured navigation or new functionality, it's a new build - we'll tell you that upfront.

Why does the calculator show a price range rather than a fixed quote?

Software estimates without a scoping conversation are usually wrong by 20-30%. The range is our way of being honest about that: the centre of the range is what we'd quote for an average project at that scope, with £2,000 of headroom either side for the things we don't know yet. A 30-minute call closes that gap.

How do payments work?

We split every project 50/50: 50% at kickoff, 50% at launch. No hidden fees, no surprise change requests. If scope shifts mid-project, we agree it in writing before any work starts. For projects over £20,000 we can structure milestone payments instead - just ask.

Are hosting and ongoing maintenance included?

Builds include 30 days of post-launch support and full handover. Hosting is yours (we recommend Cloudflare Pages for Headless, ~£0-£15/month, or your existing host for WordPress). For ongoing updates, monitoring and improvements after the first 30 days, we offer a separate retainer matrix - pick the tier that matches how active you want us to be.

What happens after I get my estimate?

You'll get the breakdown by email and a one-click link to book a 30-minute scoping call. On that call we walk through your inputs, flag anything we'd quote differently, and send a fixed-price proposal within 48 hours. No obligation, no follow-up drip if you're not ready.
