Website Redesign Cost: What Agencies Quote and Why It Varies

Website redesign cost is the total investment to rebuild an existing site, ranging in 2027 across Europe from €1,500 to €3,000 for a high-converting landing page relaunch, €4,500 to €9,000 for a multi-page corporate website redesign, and €12,000 to €25,000+ for custom web portals and SaaS platforms.

Headline figures alone rarely tell a buyer why two agencies price the same brief so differently. What follows is the operational breakdown underneath every proposal: how budget is allocated across engineering and UX phases, which hidden technical costs agencies leave out, and how to separate a lean quote from an incomplete one. The step-by-step execution workflow is covered in our website redesign guide.

In 2027, European agency quotes fall into three deliverable tiers based on architecture, template count, and system integrations. At Vezert, benchmark budgets run from €1,500 to €3,000 for a landing page relaunch, €4,500 to €9,000 for a corporate website redesign, and €12,000 to €25,000+ for custom web portals, with full deliverables listed on our pricing page.

For a focused single-page or campaign relaunch (€1,500 to €3,000), the budget covers conversion-focused wireframing, custom visual design, responsive frontend build, analytics event tracking, and Core Web Vitals optimization. A multi-page corporate website redesign (€4,500 to €9,000) typically spans ten to twenty-five pages with a modular UI design system, headless or modern CMS configuration, structured data markup, and a verified 301 redirect map.

When a redesign involves a custom web portal, SaaS product marketing ecosystem, or multi-system enterprise architecture, budgets start at €12,000 to €25,000+ and can reach €35,000 to €80,000 in broad traditional agency tenders that bundle forty-page copywriting, five-language localization, and custom ERP middleware. Two rules apply to every tier: the lower bound assumes approved copy is ready before build starts, and a well-scoped €6,000 to €9,000 rebuild with a proper migration protocol always outperforms a €30,000 rebuild that drops URL equity.

Most disputes about a redesign invoice trace back to a quote that never itemized what it covered. A quote worth comparing separates the project into discrete engineering and UX phases, each with a clear cost share and an explicit assumption attached, so that removing a line visibly removes work rather than quietly removing quality.

Across our 2027 corporate redesign benchmarks, a balanced budget allocates 30% to frontend and CMS engineering, 25% to the UI design system and interactive prototyping, 20% to UX research and information architecture, 15% to content migration and 301 SEO redirect protocols, and 10% to quality assurance, accessibility, and Core Web Vitals testing. The table and chart below show how those phases break down.

Two agencies given the same brief will routinely quote €6,000 to €9,000 on one side and €18,000 to €25,000+ on the other, and both can be acting in good faith. The gap almost never comes from hourly rates. It comes from four assumptions that the brief did not pin down and each supplier resolved differently.

Who writes the content. One quote assumes you deliver approved copy for forty pages ready for import. The other assumes the agency researches, writes, and edits every commercial page. That single assumption regularly shifts a quote by 25% to 35%.

Whether SEO migration is in scope. Crawling legacy URLs, mapping 301 redirects, and running post-launch verification take real engineering hours. A quote that never mentions them has either absorbed them silently or excluded them, and you cannot tell which by looking at the bottom line.

How many unique templates. Six modular templates powering forty pages is a completely different engineering scope from forty bespoke page layouts, even though the final URL count is identical.

What happens to connected systems. Embedding a simple contact form takes hours; building a two-way CRM or ERP integration with validation and consent gating takes weeks.

Pin those four variables down in the brief and the spread between quotes collapses to a comparable range. Leave them open and you are comparing four different projects that happen to share a title.

The most expensive overruns in a website redesign come from four technical workstreams that low-cost proposals routinely omit: SEO equity preservation during migration, legacy CMS data cleanup, third-party CRM and ERP integrations, and WCAG 2.2 AA accessibility compliance. Together, these four areas account for 25% to 40% of total engineering effort on an established corporate domain.

1. SEO equity preservation during migration (10% to 15% of budget). Rebuilding a site that already ranks in search engines requires a formal website redesign SEO protocol before a single URL changes. Engineers must export a complete crawl inventory from screaming frog or log files, merge it with Google Search Console traffic data and backlink targets, and map every obsolete URL 1:1 to its new destination using single-hop 301 redirects. Dropping canonical tags, stripping structured data schemas, or breaking hreflang clusters across locales can wipe out 30% to 50% of organic pipeline within weeks of go-live.

2. Legacy CMS data cleanup and asset modernization (€800 to €2,500). Older WordPress, Drupal, or custom databases rarely export cleanly into a modern component architecture. Years of inline CSS overrides, broken page-builder shortcodes, duplicate taxonomy tags, and unoptimized PNG or JPEG uploads must be stripped and normalized before import. Automating script cleanup, converting legacy media into responsive WebP and AVIF formats, and backfilling missing alt attributes and meta descriptions require dedicated migration scripts rather than copy-paste intern hours.

3. Third-party CRM, ERP, and marketing automation integrations (€1,200 to €5,000+). Modern B2B sites act as data routers between the visitor and internal revenue systems. Connecting forms to HubSpot, Salesforce, Pipedrive, or an ERP catalog involves API authentication, custom field mapping, server-side payload validation, webhook retry queues, and strict GDPR cookie consent gating so tracking scripts only fire after explicit opt-in. Every external endpoint requires both development hours and sandbox testing against malformed inputs.

4. WCAG 2.2 Level AA compliance and European Accessibility Act readiness (€750 to €2,000). Under European accessibility regulations, public-facing commercial websites must meet verifiable WCAG 2.2 Level AA criteria. Building accessibility into the design system from day one means enforcing 4.5:1 text contrast ratios, engineering keyboard focus rings and focus-trap management for modals and menus, maintaining semantic heading hierarchies, and sizing interactive touch targets to at least 24 by 24 CSS pixels. Retrofitting accessibility after launch costs three to four times more than engineering it directly into the UI component library.

Read a quote from its operational assumptions rather than the total at the bottom. The final price is the least informative part of the document because it only carries meaning once you verify what the supplier assumes about your copy, your template count, your redirect map, and your connected systems.

Five written questions turn any proposal into a document you can audit:

• How many total pages, and how many unique templates? Pages tell you editorial volume; unique templates tell you design and frontend cost.
• Who writes each page, and by what deadline? If the answer is your internal team, that work carries an internal payroll cost and a high schedule risk even if it never appears on the agency invoice.
• Is the 301 redirect map included, and who verifies it? According to Google Search Central, redirects should resolve in a single hop without chains, and someone must build, deploy, and test that mapping table before launch.
• What is explicitly excluded? A trustworthy quote includes a clear exclusions section covering stock photography, paid font licenses, third-party SaaS subscriptions, or copywriting. The absence of an exclusions list is the warning sign.
• What happens after launch, and for how long? Warranty and hypercare windows vary from zero to three months and rarely appear in the headline figure.

If a supplier cannot answer these five questions in writing, the figure on the page is a rough estimate dressed up as a fixed quote.

A low quote is not automatically a bad one when it reflects a focused scope and reusable component architecture. It becomes a problem only when the price is low because mandatory technical work has been silently stripped out, shifting those costs onto your team weeks after the final invoice is paid.

The five omissions that cost the most after launch, ranked by impact:

1. No SEO migration line. The single most damaging omission because it surfaces as lost search rankings weeks after go-live. Google's documentation on site moves with URL changes details the required mapping steps, and none happen automatically.
2. No content production or formatting. Forty pages of copy quietly become your internal team's weekend project, delaying launch by months.
3. No Core Web Vitals performance budget. Sites get heavier during a redesign unless engineering sets strict asset limits. According to Google's guide to Core Web Vitals, LCP, INP, and CLS measure real user experience, meaning regressions surface after launch when cheap contractors have left.
4. No WCAG 2.2 accessibility verification. Fixing contrast failures, keyboard focus traps, and unlabelled inputs after launch requires rebuilding finished templates.
5. No cross-device QA. Cutting testing hours lowers the quote immediately and breaks mobile forms on day one.

Ask every supplier to price missing lines as add-on options rather than haggling over the total. A quote that scales transparently when you add migration and QA back is a sign of an honest partner.

Comparing three agency proposals is straightforward once they describe the exact same engineering scope, and impossible before that. The real buyer work lies in normalizing the underlying assumptions rather than judging the graphic layout of the PDF, and the entire exercise takes about one hour.

Build a comparison sheet with one row per phase from the budget table above and one column per agency. Fill in every cell, paying special attention to blank ones, because an empty cell is your primary finding. Where a supplier left migration, accessibility testing, or CMS training unpriced, ask them to assign a euro figure rather than assuming it is free.

Next, lock the operational variables across all three vendors: set the same page count, the same number of unique templates, the same copywriting split, and the same CRM integration list. Request updated numbers on that baseline. Most of the artificial spread vanishes at this step, leaving genuine differences in technical architecture and seniority.

Only after normalization does the bottom-line figure mean anything. Comparing unadjusted totals is how organizations select the supplier who read the brief least carefully.

Certain project requirements raise a website redesign budget for sound commercial reasons, while others inflate the invoice through avoidable process friction. Separating legitimate scope drivers from preventable waste protects both your capital expenditure and your post-launch total cost of ownership.

Legitimate cost drivers include the number of unique UI templates, the volume of original copywriting, multi-language architecture, authenticated portal features, complex CRM or ERP data syncs, and high-stakes URL restructurings on sites with strong organic authority. Each of these items represents measurable design, engineering, and QA hours.

Avoidable cost drivers include commissioning bespoke layouts for pages that should share a standard template, rewriting the brief after Figma sign-off, adding new executive stakeholders mid-build, and altering URL slugs simply because a new CMS formats paths differently by default. Changing URLs without a structural reason creates pure migration overhead and unnecessary ranking risk.

Multilingual rollouts and ongoing upkeep also require upfront math. Every additional language multiplies content entry, hreflang validation, and QA across every template. Equally important, buyers should pair their build quote with a realistic forecast of post-launch website maintenance cost covering hosting, security patching, CMS updates, and continuous performance monitoring over the next twenty-four to thirty-six months.

Content production and structured content migration are the most underestimated items in every redesign budget, and the ones most frequently omitted from initial agency proposals. UI design is bounded work: six to ten modular templates, approved once in Figma and reused across the site. Writing or restructuring forty commercial pages is unbounded work until someone scopes it page by page.

This asymmetry is why content is the number-one cause of delayed website launches. Frontend engineering and CMS configuration progress against a predictable technical specification, whereas unwritten copy has no specification and stalls final assembly. Our website redesign checklist assigns a named owner, source data, and a delivery deadline to every single URL before design begins for exactly this reason.

For your budget, decide who writes and formats the copy before requesting agency quotes, not after signing a contract. If your internal team handles copywriting, assign a realistic hour count and internal cost to their calendar rather than treating their time as free. If the agency handles copywriting, expect it to represent 15% to 25% of the total quote, and treat any suspiciously cheap content line as a sign that they plan to paste old text into new boxes.

Preparing a tight request for quotes takes a single afternoon and stops agency proposals from scattering across incompatible price bands. Four concise documents give any serious supplier enough precision to price your project accurately without requiring you to hire a consultant or draw wireframes first.

First, export your current URL inventory: list every live page alongside its twelve-month organic traffic and conversion count, plus the new pages you plan to add. Second, state explicitly who writes the copy and prepares the media for each page tier. Third, list every external tool the site must integrate with, naming the exact CRM, form handler, analytics platform, and cookie consent manager. Fourth, define the primary commercial metric the relaunch must improve, with your current baseline number next to it.

Send those exact four documents to three agencies and ask them to itemize their quote across the five core budget phases shown in this guide. You will receive proposals that can be compared line for line, shifting your selection calls from guessing what is included to evaluating engineering quality.

If you prefer to scope your project through a direct technical review rather than a formal tender, that is how our corporate website engagements begin.
