The verdict in three sentences
A premium brand website redesign in London sits between 8,000 and 22,000 EUR excl. VAT in 2026, depending on UX depth and page count. The heaviest line item remains development (40% of budget), followed by design and UX. Done well, a redesign lifts qualified leads by +30 to +60% within twelve months: it's a commercial investment, not a cosmetic expense.
2026 price ranges in London
The London market is mature: agencies charge a day rate of 550 to 750 EUR excl. VAT for a senior profile. Here are the 2026 orders of magnitude for a full redesign.
| Redesign type | Pages | Budget excl. VAT | Timeline |
|---|---|---|---|
| Visual refresh | 5-8 | 8,000 - 11,000 EUR | 6-8 wks |
| UX + design overhaul | 8-15 | 12,000 - 16,000 EUR | 8-10 wks |
| Premium custom redesign | 15-25 | 17,000 - 22,000 EUR | 10-12 wks |
| Annual maintenance | - | 1,200 - 3,600 EUR/yr | ongoing |
A serious redesign takes 8 to 12 weeks including scoping and QA. Beware quotes at 4,000 EUR: they usually hide an unpersonalised template with no conversion work.
How the budget breaks down
A well-built redesign budget always splits the same way. Understanding it helps you challenge a vague quote.
| Line item | Share | On 16,000 EUR |
|---|---|---|
| UX (audit, IA, wireframes) | 20% | 3,200 EUR |
| UI design (mockups, brand) | 25% | 4,000 EUR |
| Development (build, CMS) | 40% | 6,400 EUR |
| Technical SEO + content | 15% | 2,400 EUR |
If an agency bills 60% development and 5% UX, be wary: the site will look good but won't guide visitors to contact. UX is what turns a visitor into a lead.
Mini case study
Marc, director of an industrial trading SME in London (24 staff), rebuilds his six-year-old website for 15,000 EUR excl. VAT. His old site generated 8 quote requests per month. After the redesign (reworked UX, solution pages, optimised forms), he reaches 13 requests per month, up +62%. Each quote converts at 25% into an order with 4,200 EUR average margin. The 5 extra leads per month yield 5 x 0.25 x 4,200 = 5,250 EUR monthly margin, or 63,000 EUR per year. The redesign pays for itself in under three months.

FAQ
Why does a redesign cost more than a new site?
Not always, but you must audit the existing site, migrate content and often handle 301 redirects to preserve earned SEO. This migration work runs 1,000 to 2,500 EUR depending on page volume.
How long does the project really take?
Expect 8 to 12 weeks. The biggest delay factor is client-side sign-off: prepare your content and approvals upfront to hold to 8 weeks.
Do I need to redo SEO after a redesign?
Yes, technical SEO is included (15% of budget), but plan a 3-to-6-month support phase to secure rankings, typically 300 to 600 EUR/month.
Is the CMS included?
In a premium redesign, yes: you edit pages without a developer. A headless CMS or well-configured WordPress is part of the 40% development.
What ROI should I realistically expect?
A realistic 2026 order of magnitude: +30 to +60% qualified leads over twelve months if UX and SEO are handled well. ROI depends mostly on your average deal value.
