The verdict in three sentences
A premium website redesign in London sits between £6,000 and £18,000 in 2026 depending on the level of bespoke work, with an 8 to 12 week timeline. The line item that justifies the gap isn't the page count but technical performance and the design system: an LCP brought below 2.5s delivers +32% conversion on average. Reject any quote that fails to clearly separate design, build, content and ongoing maintenance.
What a premium redesign actually covers
A redesign is not a facelift. It includes an audit of the existing site (SEO, performance, accessibility), a new information architecture, a reusable design system, a performant build and a migration plan with no ranking loss. A serious London agency day rate sits between £380 and £550 in 2026; below £300 you are mostly funding a lightly customised template.
| Approach | Price 2026 | Timeline | For whom |
|---|---|---|---|
| Customised template | £2,500 – £5,000 | 3 – 5 weeks | Micro-business, tight budget |
| Semi-bespoke | £5,000 – £9,500 | 6 – 9 weeks | Established SMB, polished image |
| Full bespoke premium | £9,500 – £15,000 | 8 – 12 weeks | SMB/mid-market, strong differentiation |
| Design system + motion | £13,000 – £22,000 | 10 – 14 weeks | High-end brand |
Breakdown of a £10,000 budget
To understand where the money goes, here is a typical breakdown of a semi-bespoke premium project at £10,000. Use it as a reading grid to compare quotes.
| Line item | Share | Amount | Comment |
|---|---|---|---|
| Discovery & UX | 12% | £1,200 | Workshops, sitemap, wireframes |
| UI design | 22% | £2,200 | Mockups, design system |
| Build & dev | 38% | £3,800 | Performant front, CMS, responsive |
| Content & SEO | 15% | £1,500 | Copywriting, markup, migration |
| QA & launch | 8% | £800 | Testing, accessibility, deploy |
| Project management | 5% | £500 | Coordination, tracking |
On top of this comes maintenance: budget £130 to £350/month depending on service level (updates, security, small changes, monitoring). It is a recurring line to plan from day one, not an option.

Mini case study
Mark runs a 28-person London SMB in thermal engineering. His site dates from 2018, loads in 4.8s and converts 1.2% of visitors into quote requests. On 3,500 qualified visitors a month that means 42 leads. After a semi-bespoke redesign at £9,500 bringing LCP to 2.1s, conversion rises to 1.6% (+32%), or 56 leads/month, +14 leads. With a 20% sales close rate and an average deal of £4,000, those 14 extra leads generate about 2.8 jobs/month, or £11,200 of additional monthly revenue. The redesign pays for itself in under a month of commercial outperformance.
FAQ
Why does a premium redesign cost more than a £1,800 site? Because 60% of the work is invisible: audit, architecture, performance, accessibility and SEO. A £1,800 site is a filled-in template; it ages badly and needs redoing every two years.
How long does a redesign take in London in 2026? Expect 8 to 12 weeks for a semi-bespoke project, including 2 to 3 weeks of discovery and design. A timeline under 4 weeks usually signals a template with no UX work.
Will my rankings drop after the redesign? Not if a migration plan is in place: 301 redirects, keeping strategic URLs, clean markup. A well-run redesign usually gains traffic thanks to Core Web Vitals.
Do I really need a monthly maintenance plan? Yes. Without security and dependency updates, a premium site degrades within 12 to 18 months. Maintenance at £130–£350/month protects an investment of several thousand pounds.
Template or bespoke for a London SMB? If your brand image is a commercial differentiator, semi-bespoke (£5,000–£9,500) is the best value. Templates suit tight budgets with no positioning stakes.
