B2B Website Redesign Cost Benchmark: What London Firms Pay in 2026

The verdict in three sentences

A premium B2B website redesign of 8 to 15 pages costs between GBP 6,500 and GBP 15,000 in 2026 London, depending on custom design and SEO depth. A simple restyle (same content, new theme) stays at GBP 3,800 but fixes neither structure nor commercial performance. The gap reads line by line: design 30%, build 40%, SEO/content 20%, QA 10%.

The 2026 ranges in London

London B2B agencies bill day rates of GBP 500 to GBP 750 for a senior profile. Here are the 2026 orders of magnitude for a redesign by ambition level.

A premium quote is usually stated ex-VAT; add 20% VAT where applicable. For a VAT-registered SME the tax is recoverable, which is why buyers reason in ex-VAT figures.

Breaking down a premium quote

A readable quote splits the budget into four items. On a GBP 12,000 premium redesign, the typical 2026 split looks like this.

Line itemShareAmount (GBP)What it covers
UX/UI design30%3,600Wireframes, art direction, component system
Build40%4,800Responsive dev, CMS, performance
SEO / content20%2,400Structure, tags, 8-10 pages of copy
QA / launch10%1,200Browser tests, accessibility, go-live

When an agency quotes a day rate far below market, check who actually delivers: unmanaged offshore subcontracting often explains the gap, at the expense of QA and SEO.

Mini case study

James, managing director of a 40-person industrial SME in Croydon, runs a 2019 site that generates 6 quote requests a month. He invests GBP 11,000 in a premium redesign, targeting 15 requests/month. His average B2B deal is GBP 8,000 at a 20% close rate. The 9 extra requests yield 1.8 sales/month, or GBP 14,400 in additional monthly revenue. The redesign pays back in under one month of incremental revenue, before margin.

FAQ

What is the real difference between a GBP 3,800 restyle and a GBP 12,000 redesign?

A restyle changes the skin without reworking structure or SEO; it does not move conversions. A premium redesign reworks structure, journeys and performance, with a measurable +50% to +150% lift on inbound enquiries.

How long does a premium redesign take?

Budget 8 to 10 weeks in 2026 for 12-15 pages, including 2 weeks of scoping and design. A 3-week timeline quoted for premium work is a red flag on depth.

Does bilingual delivery change the price much?

Yes: a second full language adds around 25%, because it doubles QA, SEO and editorial upkeep, not just translation.

Is maintenance included?

Warranty typically covers 3 months after launch. Beyond that, a maintenance contract at GBP 90 to 220/month covers updates, backups and small changes.

Can payment be staged?

Usually across 3 milestones: 30% on order, 40% on design sign-off, 30% on delivery. Some agencies offer a monthly spread over 6 to 12 months.
