The verdict in three sentences
For a London engineering consultancy, the website is first of all a reference library an evaluator can scan in 30 seconds before scoring a Selection Questionnaire or a framework bid. A budget of 25,000 to 55,000 GBP (about 29,000 to 64,000 EUR) covers quantified project case studies, a map of delivered schemes and downloadable expert CVs in client formats. One additional commission won on the back of that credibility repays the investment several times over.
What public clients and frameworks actually check
Under the Procurement Act 2023 regime, contracting authorities such as National Highways, local councils, the Environment Agency or Network Rail shortlist suppliers on experience, people and social value. Evaluators cross-check written submissions with what they find online: real scale, relevant schemes, named experts, consistent figures. A thin brochure site raises doubts. A site organised by sector (highways, water, structures, rail) and by client reassures immediately.
| Evaluation criterion | Indicative weight | What the website must show |
|---|---|---|
| Organisational experience | 20 to 30 % | Years trading, fee income, accreditations (ICE, IStructE, CHAS) |
| Comparable projects (last 5 years) | 30 to 40 % | Case studies with value, client, duration, role |
| Key personnel | 25 to 35 % | CVs in client format, chartered status, years of experience |
| Geographic coverage | 5 to 10 % | Map of schemes across London, the South East, the UK |
| Technical capability | 5 to 10 % | BIM Level 2 / ISO 19650, software, in-house survey |
| Quality, carbon and social value | 5 to 10 % | ISO 9001, ISO 14001, PAS 2080, social value reporting |
The goal is not to replace the bid document but to make every claim in it verifiable online. That is often what moves a firm from ninth to sixth on a shortlist.
Website components and their 2026 cost
An engineering consultancy does not need e-commerce or a complex client portal. It needs a clean, filterable reference database and a back office the bid coordinator can update after each project completion.
| Module | 2026 range | Lead time |
|---|---|---|
| Bespoke design, 15 to 25 pages | 7,500 to 13,000 GBP | 3 weeks |
| Filterable reference database (sector, client, region, value) | 6,000 to 11,000 GBP | 2 weeks |
| Interactive map of geotagged projects | 2,500 to 5,000 GBP | 1 week |
| Expert profiles with CVs generated in client format | 4,000 to 8,500 GBP | 2 weeks |
| Internal, password-protected bid tracker page | 3,500 to 7,000 GBP | 1 to 2 weeks |
| Migration of 40 to 80 existing case studies | 1,500 to 4,000 GBP | 1 week |
| SEO, hosting for 1 year, backups | 1,500 to 2,500 GBP | ongoing |
An essential scope (design, references, map, CVs) sits around 25,000 GBP. The full version, with automated CV generation and an internal bid tracker, approaches 55,000 GBP. Annual maintenance runs between 3,500 and 8,000 GBP.
Mistakes that cost shortlist places
First mistake: publishing references with no value and no precise role. Evaluators want to know whether the firm led the commission or was a subconsultant, and on what construction value. Second mistake: CVs as images or in free format, impossible to reuse. Third mistake: a slow site whose project pages weigh 8 MB, which reads badly on the phone of a client project manager on site. A CDN and pages under 1.5 MB fix that.
Finally, accessibility matters: public sector buyers increasingly expect WCAG 2.2 AA on supplier sites, and it signals the same rigour they expect in deliverables.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
James, managing director of a 22-engineer civil and structural consultancy in London, bids on 40 tenders a year and wins 5, with average fees of 140,000 GBP. He invests 38,000 GBP in a site with 60 case studies, 14 expert CVs and a project map. If his shortlisting rate rises from 30 % to 38 % while his post-shortlist win rate stays stable, he wins roughly one more commission per year. Additional fee income: 140,000 GBP, about 3.7 times the cost of the site. Even at a 15 % net margin, the extra profit (21,000 GBP) covers more than half the site in year one and all of it, plus maintenance, within two years.
FAQ
How much does an engineering consultancy website cost in London in 2026?
Budget about 25,000 GBP for a professional site with references and CVs, and up to 55,000 GBP with client-format CV generation and an internal bid tracker. Annual maintenance is 3,500 to 8,000 GBP.
Can we publish public contract values?
Yes for contracts already published on Find a Tender or Contracts Finder, which are public. For private clients, show a range (for example 5 to 10 million GBP) after written client approval.
How long does it take to go live?
Between 8 and 12 weeks, including 1 to 2 weeks on the firm's side to gather case studies, site photos and current CVs. Migrating 60 references takes about 5 days of data entry.
Are expert CVs online a GDPR issue?
Publish a summary profile (degree, chartered status, 3 to 5 key projects) and protect the full CV behind a private link sent to evaluators. Each expert's written consent is required under UK GDPR.
Does the site also help recruit engineers?
Yes: a careers page with 3 to 5 roles a year attracts qualified candidates and cuts agency fees, usually 15 to 25 % of first-year salary.
