The verdict in three sentences
In 2026, an 8 to 15 page B2B website redesign for a London SME lands between 6,000 and 18,000 EUR, depending on whether you adapt a premium theme or build a fully bespoke UI. The realistic timeline is 6 to 10 weeks, with an agency day rate of 450 to 650 EUR that drives 70% of the invoice. Done well, a redesign lifts inbound quote requests by an average of +35%, paying for itself within 8 to 14 months.
What you actually pay: the 2026 line items
An industrial SME (20 to 80 staff) isn't buying a website: it's buying a B2B lead channel. The price gap between two quotes comes mostly from design (theme vs bespoke) and the volume of technical content to produce (product sheets, references, case studies).
| Line item | Entry level | Bespoke premium |
|---|---|---|
| UI design (mockups) | Premium theme 60-200 EUR | Bespoke UI 3,000-6,000 EUR |
| Integration / development | 2,500-4,000 EUR | 5,000-8,000 EUR |
| SEO copywriting | 80-120 EUR/page | 120-180 EUR/page |
| Pro photo / video | 600-1,200 EUR | 1,500-3,500 EUR |
| Annual maintenance | 900-1,400 EUR | 1,600-2,400 EUR |
| Project total | 6,000-9,000 EUR | 12,000-18,000 EUR |
The classic trap: underestimating content migration. Moving 40 product sheets off an old WordPress easily adds 1,500 to 3,000 EUR that few entry-level quotes include.
Premium theme or bespoke UI: the real trade-off
| Criterion | Premium theme | Bespoke UI |
|---|---|---|
| Design cost | 60-200 EUR | 3,000-6,000 EUR |
| Time to build | 3-5 weeks | 7-10 weeks |
| Visual differentiation | Low | High |
| Performance (Lighthouse) | 70-85 | 90-98 |
| Scalability | Limited by theme | Full |
| Lifespan before redesign | 3-4 years | 5-7 years |
For an industrial SME selling in a competitive market (engineering, food processing, plastics), bespoke is justified as soon as the website is the first commercial touchpoint. If it mainly serves as a business card, a well-integrated premium theme is plenty.
Mini case study
Claire, CFO of a precision engineering SME in North London (55 staff), runs a 6-year-old WordPress generating 12 quote requests a month. Average contract value: 18,000 EUR, quote-to-order conversion 22%. She invests 13,500 EUR in a bespoke redesign. At 6 months: +35% requests, i.e. 4 extra leads a month. At 22% conversion that's 0.9 more contracts monthly, roughly 16,000 EUR of added monthly revenue. The redesign is repaid in under a month of marginal revenue, even at a 20% margin.

How long does a redesign take?
Between 6 and 10 weeks for an 8-15 page site: 2 weeks of scoping/UX, 3-4 of design and build, 2-3 of content and QA. A rush job can drop to 4 weeks with a theme.
What annual maintenance should I budget?
