The verdict in three sentences
A premium B2B website redesign for a London company runs between £20,000 and £40,000 with UK agencies in 2026, while the same scope costs €14,000-€24,000 through a French-speaking nearshore agency. The heaviest line is rarely design or development — it is usually the content and UX scoping that decision makers underestimate. Plan for 8 to 12 weeks and budget for VAT (20 %), since agency quotes are stated ex-VAT.
Where each pound goes: the line-by-line breakdown
The instinct when receiving a £30,000 lump-sum quote is to find it opaque. Here is the typical split of a premium project, with the ranges observed in the UK market in 2026.
| Line item | 2026 range (ex-VAT) | Share of budget |
|---|---|---|
| Discovery & UX (workshops, IA, wireframes) | £3,000 - £6,000 | 18-20 % |
| UI design (Figma mockups, design system) | £3,500 - £7,000 | 22 % |
| Headless front-end build (Next.js) | £5,000 - £10,000 | 28 % |
| Content & SEO copywriting | £1,800 - £4,000 | 12 % |
| QA, testing, go-live | £1,200 - £2,500 | 8 % |
| Project management & training | £1,500 - £3,000 | 10 % |
A firm that supplies its own copy and photography can save £2,000-£4,000 on content, but at the cost of a longer timeline if deliverables lag.
The recurring costs nobody quotes
The upfront quote is only the visible part. A premium site then lives through maintenance and hosting. Over three years, these recurring items often represent 30-40 % of the build cost.
| Recurring item | Monthly 2026 | 3-year cost |
|---|---|---|
| Maintenance (updates, security, fixes) | £300 - £520 | £10,800 - £18,720 |
| Managed hosting | £35 - £110 | £1,260 - £3,960 |
| Domain + SSL certificate | £3 - £7 | £108 - £252 |
| Monthly SEO & content (optional) | £450 - £1,100 | £16,200 - £39,600 |
Budgeting maintenance from day one avoids the "abandoned site" effect after 18 months, the leading cause of premature redesigns.

Mini case study
Take James, managing director of a precision-engineering SME in London (52 staff). His 2019 site generates 4 quote requests a month. He approves a redesign at €18,000 ex-VAT through a nearshore French-speaking agency (versus a £32,000 local quote), adds maintenance at €400/month and hosting at €75/month. Total year-one cost: €18,000 + (€475 × 12) = €23,700. If the new site lifts requests from 4 to 9 per month with an average contract of €12,000, the investment pays back within the second quarter on the first signed deals.
FAQ
Why does a premium site cost 3-5x a £5,000 site? The difference is UX scoping, bespoke design and a high-performance headless build. A £5,000 site uses a generic theme; a £24,000 site is engineered to convert an industrial visitor into a qualified lead, loading in under 1.5 s.
Do I need to budget VAT? Yes. B2B quotes are ex-VAT. On a €18,000 net project you disburse €21,600 incl. VAT, reclaimable but still a cash-flow hit.
What payback period is reasonable? For a premium B2B site, expect 9-18 months depending on your average contract value and the extra lead volume generated.
Can payment be staged? Most agencies offer a 30/40/30 schedule (deposit, mid-project, delivery). Some allow spreading over 6-12 months for a small premium.
Why is nearshore cheaper? A French-speaking agency in Dakar bills day rates of €350-€550 versus £700-£1,100 in London, a 40-55 % gap at equal quality (2026 order of magnitude).
