Website Redesign Cost: The Complete 2026 Breakdown

Table of Contents

Website redesign quotes for the same project can range 5x in price. £20k on one proposal, £100k on another for an identical brief. That variance isn’t random. This guide breaks down what drives website redesign cost in 2026 — strategy vs execution costs, SEO vs conversion prioritisation, platform choice, and realistic budgets by business size.

Website Redesign Cost by Business Stage

Startup / Pre-Product (5–10 pages):

UK: £8,000–18,000
USA: $10,000–25,000
Timeline: 6–10 weeks
Includes: Strategy, design, build, basic CMS, analytics setup, launch.

Growth-Stage B2B / SaaS (15–30 pages):

UK: £20,000–50,000
USA: $25,000–65,000
Timeline: 10–16 weeks
Includes: Full strategy + positioning, design system, CMS architecture, CRO roadmap, analytics instrumentation, launch + monitoring.

Scale-Stage or B2B Complex (25–50 pages, migrations):

UK: £40,000–100,000
USA: $50,000–130,000
Timeline: 14–24 weeks
Includes: Full audit, repositioning, multi-team discovery, content migration, SEO-safe redirect strategy, advanced integrations, training, post-launch CRO program.

Enterprise (50+ pages, multi-regional, high integration):

UK: £80,000–300,000+
USA: $100,000–400,000+
Timeline: 20–32 weeks
Includes: Full strategy, multiple design systems, content audit + migration, advanced CRM/tech stack integration, international SEO, white-glove support.

What Actually Drives Cost

Cost multipliers (add 20–50%):

Content migration from old site (100+ pages).
SEO-safe migration with 301 redirect strategy.
Platform change (WordPress → Webflow, etc.).
Repositioning or messaging strategy (adds discovery phase).
Complex CRM/tech integrations.
Multi-regional or multi-language variants.
Custom CRO program post-launch.

Cost reducers (subtract 20–40%):

Design already complete (just building).
No platform migration (same CMS).
Limited integrations (forms + analytics only).
Pre-aligned messaging (no repositioning needed).
Smaller scope (under 15 pages).

Fixed-Price vs Time-and-Materials

Fixed-price (best when): Scope is locked, timeline is predictable, changes are defined upfront. Protection for both parties, but quoter needs buffer for unknowns.

Time-and-materials (best when): Scope is open, discovery is ongoing, or complexity is uncertain. Flexibility, but budget risk on your side. Always cap with a total ceiling.

Hybrid (best for real projects): Fixed discovery phase + T&M build phase with capped hours. Balances clarity and flexibility.

Post-Launch Costs Often Overlooked

Retainer support: £500–2,000/month for ongoing updates and monitoring.
CRO program: £2,000–8,000/month for structured conversion testing (often more valuable than the initial redesign).
Content updates: £1,000–5,000/month for active publishing and refresh cycles.
Performance monitoring: Included in retainers or £200–500/month separately.

Total cost of ownership over 24 months: redesign cost + 12–24 months of retainers = often 2–3x the initial redesign budget.

Negotiating Better Rates

Lock scope early. Scope creep adds 30–50% to final cost. Define what’s in, what’s out, and what costs extra upfront.
Bundle design + build with one agency. Two separate vendors (designer + developer) adds coordination overhead.
Bundled retainer can reduce rates. “£40k project + £3k/month retainer for 12 months” might be quoted lower than separate engagements.
Longer commitment = lower rates. 12-month retainer usually costs 15–20% less per month than month-to-month.

FAQ

Why do redesign quotes vary so much?

Platform choice, scope complexity, agency location/tier, approach (template vs custom), post-launch support. All of these swing price 2–3x.

Is a cheap redesign ever a good idea?

No. Redesigns that are “cheap” usually cut SEO, CRO planning, or post-launch support. You end up with a beautiful site that loses traffic or doesn’t convert. Spend appropriately.

Should I include CRO in the redesign budget?

Yes. Post-launch CRO usually returns 2–3x the initial redesign investment. Don’t treat redesign and CRO as separate projects.

What’s included in a retainer post-launch?

Usually: hosting monitoring, plugin/tool updates, bug fixes, minor content changes. Define upfront: what’s included, what’s billed hourly, what’s out of scope.

Can I DIY a redesign on Webflow or WordPress?

If you have design and technical skills, yes for a small site. For anything client-facing or conversion-focused, the time cost usually outweighs budget savings.

Conclusion: Budget Based on Scope, Not Platform

Website redesign cost is determined by what you’re actually redesigning (strategy, content, positioning, technical migration) — not the platform itself. Two teams on Webflow can price 5x apart based on scope and approach.

Use this breakdown to evaluate proposals and negotiate confidently. The right cost is the cost that matches your actual scope and includes post-launch support.
