The verdict in three sentences
For an engineering consultancy, the website is read by clients and lead consultants during bid evaluation, long before the first meeting. A site with 50 filterable case studies, team profiles and service pages costs 18,000 to 40,000 GBP in 2026, delivered in 8 to 10 weeks, with maintenance from 200 GBP a month. Return is measured in tender win rate, not traffic.
What public and private clients check on your site
A project sponsor at a housing association or a developer in London reviewing 8 submissions for a design team appointment checks three things: comparable projects (same typology, construction value and procurement route), clear capabilities (structures, MEP, sustainability, civils, BIM) and a credible team. A site showing six projects without dates or values weakens the bid instead of supporting it.
Each project should become a structured case study: client, location, construction value, RIBA stages covered, floor area, target rating (BREEAM, NABERS UK, Passivhaus), year and visuals. Filters then let a reader find 'residential, Greater London, over 10 m GBP' in ten seconds.
| Element | Essential | Standard | Advanced |
|---|---|---|---|
| Case studies | 20 pages | 50 filterable pages | 50+ with interactive map |
| Filters | Sector | Sector, RIBA stage, value, region | + rating, year, procurement route |
| Service pages | 4 | 8 | 12 with SEO content |
| Team | Single page | Director and lead profiles | Profiles + downloadable CVs |
| Careers | External link | Jobs page + application | Careers hub linked to ATS |
| Languages | English | English + French | English + 2 languages |
| 2026 budget (GBP) | 18,000 to 24,000 | 24,000 to 32,000 | 32,000 to 40,000 |
Detailed budget and timeline
The most underestimated item is writing the 50 case studies: without a fixed template and an internal owner, projects slip by weeks. We supply a template for project leads to fill in from week 1.
| Line item | Estimated cost (GBP) | Week |
|---|---|---|
| Discovery, sitemap, case study template | 2,000 to 4,000 | W1 |
| Design (brand, desktop and mobile mock-ups) | 4,500 to 9,000 | W2 to W3 |
| Development and CMS | 6,000 to 13,000 | W4 to W7 |
| Entry and formatting of 50 case studies | 2,500 to 6,000 | W4 to W8 |
| Site photography or render retouching | 1,200 to 3,500 | W3 to W5 |
| Technical SEO and service pages | 1,800 to 4,500 | W8 to W9 |
| QA, training, launch | 0 (included) | W10 |
| Maintenance and hosting | 200 GBP / month | After launch |
Mini case study
Tom, managing director of a 70-engineer multidisciplinary consultancy in London, bids on 60 tenders a year at an 18 % win rate, or 11 appointments. Average fees per appointment are 95,000 GBP. He invests 30,000 GBP in a Standard site. If the site, combined with stronger case studies in bid documents, lifts the win rate to 21 %, he wins 2 more appointments a year, or 190,000 GBP in fees. Even at a 10 % net margin, the site pays back within the first year, including 2,400 GBP of maintenance.
FAQ
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Can we show confidential projects?
Yes, by anonymising the client ('housing association, South London') while keeping typology, value and scope. Around 20 to 30 % of a consultancy's case studies are usually shown this way.
Can the site generate case studies for our bid documents?
The Advanced tier exports selected case studies as branded PDFs, saving 2 to 4 hours per submission. Across 60 bids a year, that is over 150 hours.
Do we need a French or other language version?
Yes if you target international clients or projects in Africa and the Middle East. Translating 50 case studies and key pages costs 2,500 to 5,000 GBP.
How long does it take to update a case study?
With the CMS, a new page takes about 15 minutes. We recommend adding 1 to 2 projects a month to keep the site active.
What does maintenance at 200 GBP a month cover?
Security updates, daily backups, hosting, uptime monitoring and 1 hour of changes per month. Additional work is billed at 95 GBP per hour.
