The verdict in three sentences
A truly conversion-focused UX redesign costs 9,000 to 25,000 EUR excl. VAT in 2026 and targets a +15 to +35% uplift on key conversion points (forms, contact, quote requests). The lever is not aesthetic: it comes from the heuristic audit, user testing (5-8 participants) and friction reduction in the funnel. You measure before/after with A/B testing to attribute the gain, otherwise the budget is a belief, not an investment.
Cost per deliverable
| Deliverable | 2026 cost | What it produces |
|---|---|---|
| Heuristic audit + analytics | 1,500-3,500 EUR | Prioritized friction list |
| User testing (5-8 participants) | 1,500-3,500 EUR | Verbatims, blockers |
| Wireframes of key pages | 2,000-5,000 EUR | New journeys |
| UI + design system | 3,000-8,000 EUR | Final reusable mockups |
| Integration + A/B testing | 2,000-5,000 EUR | Uplift measurement |
| Total | 9,000-25,000 EUR | Measurable redesign |
A budget below 9,000 EUR delivers cosmetics with no measurement; above 25,000 EUR you enter a structural multi-journey overhaul.
Expected uplift by page type
| Page type | Average uplift | Main lever |
|---|---|---|
| Contact / quote form | +20-35% | Fewer fields, reassurance |
| Product / service page | +15-25% | Hierarchy, social proof |
| Booking funnel | +18-30% | Fewer steps, mobile |
| Homepage | +10-18% | Value proposition clarity |
| Pricing page | +12-22% | Readability, comparison |
These 2026 ballparks assume an improvable starting point and rigorous measurement. An already-optimized site plateaus lower.
Before / after: the effect of friction reduction
| Metric | Before | After redesign | Gain |
|---|---|---|---|
| Form fields | 11 | 5 | -55% |
| Funnel steps | 4 | 2 | -50% |
| Form conversion rate | 2.1% | 2.8% | +33% |
| Service page bounce rate | 61% | 48% | -13 pts |
| Time to first contact | 3 min | 1 min 20 | -55% |
Prioritization: quick wins first
You do not rebuild everything at once. The method: tackle the high-impact, low-effort quick wins first (fewer fields, clear CTAs, reassurance) which often deliver half the uplift in 2-3 weeks, then iterate on the rest via A/B testing.

Mini case study
Julian, B2B e-business manager in Amsterdam (industrial components distribution), wants more quote requests from his site.
- Redesign budget: 16,000 EUR excl. VAT (audit + tests + UI + A/B)
- Traffic: 9,000 visits/month, starting form conversion 2.0%, i.e. 180 leads/month
- After redesign, conversion at 2.7% (+35%): 243 leads/month, i.e. +63 leads
- With a lead-to-client rate of 8% and an average deal of 4,500 EUR, that is ~5 more clients per month, or ~22,500 EUR of additional monthly revenue.
The redesign pays back in less than one month of extra revenue. The UX budget is not a design expense but a measurable commercial lever.
FAQ
Does a prettier site convert better? Not mechanically. Conversion comes from friction reduction and clarity, not aesthetics alone. A gorgeous site with an 11-field form converts poorly.
How many participants for useful user testing? 5 to 8 are enough to surface most major issues. Beyond that, returns drop sharply for an SME budget.
What uplift should I promise my management? A ballpark of +15 to +35% on key pages, subject to A/B measurement. Avoid anyone guaranteeing a precise figure with no audit.
How long to see results? Quick wins show effect in 2-3 weeks. Full uplift stabilizes over 2-3 months of A/B iterations.
Is A/B testing mandatory? To attribute the gain, yes. Without before/after measurement, you will never know if the redesign paid off or if it was a seasonal effect.
