The verdict in three sentences
A premium business website redesign in London costs roughly GBP 14,000-34,000 (EUR 16,000-40,000) in 2026, versus GBP 2,500 for a lightly reskinned template. The gap comes from four measurable line items: UX/UI, engineering, content and SEO. Scoped well, a redesign pays for itself by driving +30-60% more qualified leads within 6-12 months.
Anatomy of a premium redesign quote in 2026
A credible quote itemises each cost rather than hiding behind one opaque figure. Here are the ranges seen in London for an 8-25 page site, as a 2026 order of magnitude.
| Line item | Range (GBP) | Cost drivers |
|---|---|---|
| Discovery & UX (IA, wireframes) | 1,800 - 4,000 | Number of templates, user workshops |
| UI / custom design | 3,500 - 8,000 | Art direction, motion, design system |
| Next.js engineering | 7,000 - 16,000 | Page count, CMS, integrations |
| Content & copywriting | 1,300 - 3,500 | Volume, photography/video |
| On-page SEO & migration | 1,800 - 4,500 | Redirects, semantic overhaul |
| Total | 14,000 - 34,000 | 8 to 25 pages |
Engineering concentrates the largest share because it governs performance (Core Web Vitals), maintainability and search ranking. That is what separates a premium site from a generic WordPress theme.
Low-cost at GBP 2,500 or premium: the honest comparison
| Criterion | Low-cost template (~GBP 2,500) | Premium redesign (GBP 14,000-34,000) |
|---|---|---|
| Delivery time | 2-3 weeks | 8-14 weeks |
| Performance (LCP) | often > 3.5 s | < 1.8 s target |
| Design | shared theme | bespoke, own identity |
| Technical SEO | basic | full migration + semantics |
| Qualified leads at 12 months | flat | +30-60% |
| Cost to redo at 2 years | high (rebuild) | low (extensible) |
Low-cost is fine to test an idea. But for a company earning a meaningful share of revenue online, under-investing is paid back in lost leads and an early rebuild.
Mini case study
Sarah, COO of a 24-person industrial supplier in London, gets 40% of her quote requests through the site. The old site converted 1.2% of 3,000 monthly visitors, or 36 leads. After a premium redesign at GBP 22,000, conversion rose to 2.0%: 60 leads/month, 24 more. With a 12% close rate and an average deal of GBP 6,000, that is about 2.9 won deals/month × GBP 6,000 = GBP 17,400 in extra monthly revenue. The build is recouped in under two months of margin.

Why does a premium redesign cost 5-10x a template?
Because bespoke design, Next.js engineering and SEO take 8-14 weeks of expert work versus a few days of template assembly. The price reflects performance, maintainability and durable commercial impact.
How long does an 8-25 page redesign take?
Between 8 and 14 weeks in 2026, driven by content readiness and approval cycles. Discovery and content production are usually what stretch the timeline.
Do we need to rewrite all the content?
Not necessarily. Budget GBP 1,300-3,500 if you outsource copy. Provide ready text and this drops sharply, but plan an SEO review of GBP 700-1,300.
What ROI is realistic?
Well-scoped redesigns average +30-60% qualified leads at 12 months (2026 estimate). The main lever is the pairing of technical performance and a rebuilt conversion path.
Can payment be phased?
Yes. The common structure is 30% on order, 40% at midpoint, 30% on delivery. Larger projects are split into lots to smooth cash flow.
