The verdict in three sentences
A credible consulting firm website quote in London sits between 12,000 and 28,000 EUR (excl. VAT), delivered in 8 to 12 weeks. A professional quote always itemizes: UX/UI 25-35%, build 30%, content and SEO 15%, project management 10%, the rest in testing and warranty. Demand a clear code-ownership transfer clause and a 30/40/30 schedule: that is what separates a serious proposal from an opaque flat fee.
Breaking down a readable quote
A partner presenting the budget to the board wants to understand where each euro goes. Here is the typical split for a 20,000 EUR project.
| Item | Budget share | Amount (of 20,000 EUR) | Deliverable |
|---|---|---|---|
| Scoping + UX | 15% | 3,000 EUR | Sitemap, wireframes |
| UI design | 18% | 3,600 EUR | Mockups, design system |
| Build/dev | 30% | 6,000 EUR | Responsive site, CMS |
| Content + SEO | 15% | 3,000 EUR | Written pages, markup |
| Project management | 10% | 2,000 EUR | Tracking, meetings, testing |
| Testing + warranty | 12% | 2,400 EUR | Tests, 3-month fixes |
This transparency reassures a board far more than a lump sum with no detail.
Ranges by level of ambition
A firm's premium positioning justifies a higher investment than a standard small business: the site is a credibility tool in front of large-account clients.
| Firm profile | Pages | 2026 budget (excl. VAT) | Timeline |
|---|---|---|---|
| Boutique (1-5 partners) | 8-10 | 12,000-16,000 EUR | 8 wks |
| Established firm | 12-18 | 17,000-22,000 EUR | 10 wks |
| Premium multilingual firm | 18-25 | 23,000-28,000 EUR | 12 wks |
Multilingual (EN/FR) adds on average 2,000 to 4,000 EUR; an insights/publications section with editorial CMS, 2,500 to 5,000 EUR.

Mini case study
Marie, partner at a strategy consulting firm in London (12 consultants), must defend a budget to the board. She receives a 21,000 EUR (excl. VAT) quote for a 16-page bilingual site with an insights section. The 30/40/30 schedule smooths cash flow: 6,300 EUR on order, 8,400 EUR on mockup sign-off, 6,300 EUR on delivery. The firm bills on average 2,500 EUR/day of engagement; if the site generates 2 extra 15-day engagements over the year, the return exceeds 75,000 EUR, more than 3 times the investment.
FAQ
Why break the quote down into percentages? Because a board approves a budget faster when it understands the structure. Seeing that 30% goes to development and 15% to content makes the spend tangible and comparable across providers.
What does the code-ownership clause mean? It states that the source code developed belongs to you after full payment. Without it, you can remain dependent on the agency for any future change.
Is SEO included in this budget? Technical and on-page SEO (markup, speed, structure) is included. Ongoing content SEO (articles, link building) is a separate monthly retainer of 600 to 1,500 EUR.
How long is the warranty? The 2026 norm is a 3-month defect-fixing warranty after delivery, included. Beyond that, maintenance of 200 to 500 EUR/month takes over.
Can we start before all content is ready? Yes, but content is the main cause of delay. Budgeting for copywriting support (included in the content item) avoids blocking delivery by 3 to 4 weeks.
