The verdict in three sentences
A premium B2B website redesign for a London firm costs between GBP 7,000 and GBP 18,000 in 2026, for a scope of 12 to 25 pages. The realistic timeline runs from 6 to 10 weeks, with annual maintenance between GBP 900 and GBP 2,400. The line item that really moves the quote is not the code but UX and content strategy, which alone absorb 25 to 30 % of the budget.
The 2026 price grid by tier
An industrial or professional B2B firm has different needs from a local shop: product catalogue, technical datasheets, documentation area, qualification form. Here are the ranges observed in London in 2026.
| Redesign tier | Pages | Price | Timeline |
|---|---|---|---|
| Design reskin (structure kept) | 8-12 | GBP 5,000 - 7,500 | 3-4 wks |
| Standard premium redesign | 12-18 | GBP 7,500 - 12,500 | 6-8 wks |
| Full redesign + advanced CMS | 18-25 | GBP 12,500 - 18,000 | 8-10 wks |
| Redesign + technical catalogue + multilingual | 25-40 | GBP 18,000 - 28,000 | 10-14 wks |
The jump between standard and full comes from information architecture: a firm with 60 product references needs a taxonomy, datasheet templates and a filterable search engine.
What each line item actually covers
An honest quote itemises the lines below. Be wary of a single lump sum with no breakdown.
| Line item | Share of budget | Indicative cost |
|---|---|---|
| Discovery + UX / wireframes | 25-30 % | GBP 2,000 - 5,000 |
| UI design (mockups) | 15-20 % | GBP 1,500 - 3,500 |
| Integration + development | 25-30 % | GBP 2,500 - 6,000 |
| CMS integration (WordPress/Strapi) | 12-18 % | GBP 1,500 - 4,000 |
| Technical SEO included | included | vs +GBP 2,000 as option |
| Copywriting / content migration | 8-12 % | GBP 800 - 2,500 |
| QA + go-live | 5-8 % | GBP 500 - 1,200 |
Technical SEO (heading structure, speed, structured data, 301 redirects from the old site) is too often sold as an option at +GBP 2,000. On a redesign it must be included: without a redirect plan you lose the ranking built over years.

Mini case study
Claire, finance director of a 40-employee B2B firm in London, must settle her 2026 marketing budget. Her old site dates from 2018, non-responsive, with a 71 % mobile bounce rate. She picks a standard premium redesign at GBP 9,800, plus maintenance at GBP 1,400/year.
Her site currently generates 12 qualified quote requests a month, with a 22 % close rate and an average deal of GBP 8,500. By going mobile-first and clarifying the CTAs she targets +25 % leads, i.e. 3 extra requests a month. At 22 % close and GBP 8,500 per deal, that is roughly GBP 5,600 of additional monthly revenue. The GBP 9,800 investment pays back in under two months of marginal gain — before any long-term SEO effect.
FAQ
What is the minimum price for a credible redesign in 2026? Below GBP 5,000 you get a shallow reskin, not a redesign. A real B2B redesign with rethought UX starts around GBP 7,000.
How much is annual maintenance? Budget GBP 900 to 2,400/year: security updates, backups, fixes and small evolutions. A contract without maintenance exposes you to known WordPress flaws within 3 to 6 months.
How much does bilingual EN/FR add? About +15 to +20 % of the budget: translated templates, hreflang, and GBP 800 to 1,500 of professional translation depending on volume.
Why does UX cost 25-30 % of the budget? Because it determines your conversion rate. A poorly designed journey can halve your leads regardless of the development budget behind it.
How long before an SEO return? Budget 3 to 6 months after go-live to recover then exceed organic traffic, provided you have a clean 301 redirect plan.
