The verdict in three sentences
For a 15-consultant London firm, a website that generates meetings with C-suite executives costs EUR 12,000 to 30,000 (about GBP 10,000 to 26,000) and ships in 8 to 12 weeks. The value does not come from design but from proof content: 10 to 20 quantified case studies and publications signed by partners. With an average engagement around EUR 60,000, a single contract won through the site repays the project two to five times.
What an agency quote contains in 2026
B2B-focused agencies structure their proposal in work packages. Price gaps come mainly from content production and the depth of CRM integration.
| Work package | Range (EUR) | Duration | Deliverable |
|---|---|---|---|
| Strategy and positioning | 2,000 to 4,500 | 1 to 2 weeks | CEO and CFO personas, sitemap, key messages |
| Custom UX/UI design | 3,000 to 7,000 | 2 to 3 weeks | Desktop and mobile mock-ups, web style guide |
| Development (headless CMS or WordPress) | 4,000 to 9,000 | 3 to 4 weeks | 15 to 30 templates, bilingual |
| Writing 10 to 20 case studies | 2,000 to 6,000 | 3 to 4 weeks in parallel | Partner interviews, anonymised client figures |
| HubSpot integration | 800 to 2,500 | 1 week | Forms, lead scoring, email sequences |
| SEO and analytics | 600 to 1,500 | 1 week | Markup, GA4 or Matomo, dashboard |
| Total | 12,000 to 30,000 | 8 to 12 weeks | Site ready to generate meetings |
The low end is a WordPress site on an adapted theme with 10 case studies written by the firm. The high end includes fully custom design, 20 cases written by an editorial consultant and HubSpot integration with visitor scoring.
Showing your day rate or not: a strategic choice
This question divides firms. Displaying a day rate filters prospects but can anchor negotiation too low. The table below summarises options seen in London.
| Strategy | Example shown | Effect on leads | Best-fit firm |
|---|---|---|---|
| Day rate shown | EUR 1,200 to 2,500 per day | Volume down 30 to 40 %, quality up | Specialist firms, short engagements |
| Engagement range | EUR 40,000 to 150,000 | Better-qualified prospects | Firms of 10 to 50 consultants |
| Packaged offers | 4-week strategic diagnostic, EUR 25,000 | Meeting booking rate of 3 to 6 % | Firms with proprietary methodology |
| No price, proof through cases | Quantified results only | More leads, filtering in calls | Premium firms with strong networks |
| ROI calculator | Estimated gain by company size | Strong engagement, 2 to 4 minutes per visit | Operational performance consulting |
For a 15-consultant firm targeting mid-market CEOs, the "packaged offers plus quantified case studies" option usually gives the best balance between volume and quality.
The pages that generate meetings
A mid-market executive spends on average 2 to 3 minutes on a consulting firm's site before deciding to get in touch. They look for three things: sectors they recognise, quantified results and faces. Prioritise one page per sector expertise, case studies in a problem, approach, result format with a figure in the headline (for example "18 % lower logistics costs in 9 months"), partner pages with photos and publications, and a short 4-field form connected to HubSpot that triggers an email from the relevant partner within 24 hours.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Isabel, partner at a 15-consultant strategy firm in Mayfair, invests EUR 22,000 in a new site with 15 case studies and HubSpot. The site attracts 1,800 qualified visitors a month, 0.8 % of whom book a meeting, or 14 meetings monthly. With a 10 % conversion rate into engagements, she wins about 1.4 engagements a month at an average of EUR 60,000. Even if only a quarter of these is directly attributable to the site, that is EUR 21,000 of monthly revenue: the project pays for itself in the second month.
FAQ
How many case studies are needed at launch?
Ten at minimum to cover 3 to 4 sectors, ideally 15 to 20. Each case takes 2 to 4 hours of interviews and EUR 150 to 300 of writing.
Is HubSpot essential?
No, but it shows which pages a prospect read before the meeting. Starter costs about EUR 20 per user per month, while Marketing Pro exceeds EUR 800 per month.
WordPress or headless CMS for a consulting firm?
WordPress is enough up to 30 templates and 2 publications a month. A headless CMS such as Sanity adds EUR 3,000 to 6,000 but delivers better performance and approval workflows.
How do you handle client confidentiality in case studies?
Anonymise the name, keep the sector, size and result figure. Around 70 % of cases published by consulting firms are anonymised.
What timeline should I really plan for?
Eight to twelve weeks, half of which depends on partner availability to approve content. Block 2 hours per week per partner.
