The verdict in three sentences
A premium B2B website redesign in London in 2026 costs between GBP 9,000 and 25,000 depending on page count, animation and technical SEO depth. A restyle at GBP 4,000-7,000 only refreshes the surface: it fixes neither the architecture, the Core Web Vitals, nor the conversion strategy. If your current site converts poorly or loads in more than 2.5 s, a full redesign is the only profitable investment — expect payback in 8 to 14 months.
Restyle or redesign: what are you really paying for
The classic trap is comparing two quotes on headline price alone. A restyle repaints the facade; a redesign rebuilds the foundations (information architecture, technical stack, conversion funnel). Here is the breakdown observed on the London market in 2026.
| Service | Restyle | Premium redesign |
|---|---|---|
| Average price | GBP 4,000 - 7,000 | GBP 9,000 - 25,000 |
| Timeline | 2 - 4 weeks | 6 - 10 weeks |
| Pages reworked | 5 - 8 | 12 - 25 |
| New technical stack | No | Yes (Next.js / headless) |
| Core Web Vitals optimisation | Partial | Complete |
| Conversion funnel rebuild | No | Yes |
| Post-launch warranty | 1 month | 3 - 6 months |
The price gap is not a comfort upgrade: it funds a stack that halves load time and doubles the site's lifespan (5-7 years versus 2-3 for a restyle).
Line items of a GBP 16,000 redesign
To frame a budget, here is how a typical premium redesign at GBP 16,000 breaks down for a London industrial or services SME.
| Line item | Share | Amount |
|---|---|---|
| Scoping, UX and site map | 12 % | GBP 1,920 |
| UI design (mockups + design system) | 20 % | GBP 3,200 |
| Front-end build (Next.js) | 28 % | GBP 4,480 |
| CMS and back-office | 15 % | GBP 2,400 |
| Technical SEO + optimised content | 13 % | GBP 2,080 |
| QA, accessibility, go-live | 8 % | GBP 1,280 |
| Project management | 4 % | GBP 640 |
On top of this, budget an annual maintenance of 12 to 18 % of the initial cost, i.e. GBP 1,920 to 2,880/year, covering security, updates and minor evolutions.
The performance gain that pays for the redesign
A heavy WordPress site loaded with plugins often shows an LCP (Largest Contentful Paint) of 2.4 to 3.2 s. A well-optimised Next.js redesign brings that LCP down to 0.9 - 1.2 s. In 2026, the measured effect on B2B sites is +18 to +30 % contact-form conversion, plus better Google ranking driven by performance signals.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Mark, managing director of an industrial joinery SME in East London, receives 22 quote requests per month through his old site (LCP 2.8 s, 1.4 % conversion). He invests GBP 16,000 in a redesign. The new site reaches an LCP of 1.0 s and a 1.9 % conversion rate (+35 %), i.e. roughly 30 requests/month. At a 20 % quote-to-sale rate and an average order value of GBP 6,500, those 8 extra requests generate 1.6 additional sales per month, or GBP 10,400 in extra monthly revenue. The redesign pays for itself in under 2 months of margin.
FAQ
How long does a premium website redesign take?
Expect 6 to 10 weeks in 2026, depending on content availability and sign-offs. A 12-page project usually ships in 7 weeks; beyond 20 pages, allow 9 to 10 weeks.
Can I keep my rankings during a redesign?
Yes, provided you build an exhaustive 301 redirect plan and preserve the URL structure of high-performing pages. A well-run redesign limits traffic loss to under 5 %, recovered within 6 to 10 weeks.
What is the price difference between WordPress and Next.js?
A Next.js stack costs 15 to 25 % more to build but halves load time and reduces annual maintenance. Over 5 years, total cost of ownership is often lower.
Do I have to pay annual maintenance?
Yes: 12 to 18 % of the initial cost, i.e. GBP 1,920 to 2,880/year for a GBP 16,000 redesign. It covers security, backups and minor changes — essential for site longevity.
At what budget does a redesign become profitable?
As soon as your site generates more than 15 requests/month: a 25 to 35 % conversion gain repays a GBP 16,000 redesign in under 6 months of additional margin for most B2B SMEs.
