The verdict in three sentences
For a 220-person construction contractor in London, the website exists first to prove its track record to clients, cost consultants and frameworks assessing tender submissions. The realistic 2026 budget is GBP 35,000 to 75,000 for the site (about USD 44,000 to 95,000), plus GBP 8,000 to 15,000 for photography and drone footage, with 40 filterable project case studies and a solid health, safety, environment and quality section. Plan 10 to 14 weeks and maintenance of GBP 1,000 to 2,000 a month.
What a client checks on your website
Before shortlisting a bid, a public or private client (local authorities, housing associations, developers, procurement frameworks) checks your website for three things: projects comparable to theirs, credible figures and an HSEQ policy. A dated site without recent photos casts doubt on your real capability.
| Website element | What the client checks | Indicative 2026 budget |
|---|---|---|
| 40 case studies (value, duration, client, photos) | Comparable references | GBP 7,500 to 15,000 |
| Filters by sector, borough, value, year | Find a similar project in 10 seconds | GBP 4,000 to 7,500 |
| Interactive map of projects across London | Geographic coverage | GBP 3,000 to 6,000 |
| HSEQ section (ISO 9001, 45001, 14001, AFR, CHAS, Constructionline) | Risk control | GBP 2,500 to 5,000 |
| Plant and workforce capacity | Delivery capability | GBP 2,000 to 4,000 |
| Careers section (engineers, site managers) | Employer appeal | GBP 3,000 to 6,000 |
| Downloadable PDF capability statement | Faster bid preparation | GBP 2,500 to 5,000 |
A PDF capability statement generated automatically from the case studies is a direct gain: your bid team no longer rebuilds references for every PQQ or tender.
The budget line by line
Visual storytelling weighs heavily on perception: drone shots of a completed school or residential block say more than long copy. Drone filming in London, however, requires CAA operator authorisation and, in much of the city, permission linked to the Heathrow and London City flight restriction zones.
| Item | Low range | High range | Comment |
|---|---|---|---|
| Scoping, sitemap, design | GBP 7,500 | GBP 15,000 | Workshops with directors and estimating |
| Build + CMS + filterable case studies | GBP 17,500 | GBP 37,500 | 25 to 40 pages + 40 projects |
| Copywriting for case studies and HSEQ | GBP 5,000 | GBP 12,500 | Figures validated by project managers |
| Additional pages (social value, ESG reporting) | GBP 4,000 | GBP 10,000 | Increasingly scored in tenders |
| Photography and drone footage | GBP 8,000 | GBP 15,000 | 8 to 15 sites, flight permissions |
| Monthly maintenance | GBP 1,000 | GBP 2,000 | New projects, security, backups |
Order-of-magnitude 2026 total: GBP 42,000 to 90,000 in year one excluding maintenance. The 10 to 14 week timeline splits into 2 weeks of scoping, 3 weeks of design, 4 to 6 weeks of build and case study entry, and 1 to 3 weeks of acceptance. Drone filming is planned in parallel, ideally on live sites to show activity.
The mistakes that lose contracts
Three mistakes come up often: projects without value or date (the client cannot compare), an HSEQ section reduced to a certification logo, and a slow mobile site, even though many decision makers browse on their phone between meetings. Aim for a load time under 2.5 seconds with images compressed to WebP.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
James, managing director of a 220-person contractor in London, bids for 25 tenders a year with a 16 % win rate, i.e. 4 contracts won at an average margin of GBP 400,000 each. His team spends 12 hours per bid gathering references. With the automatic PDF capability statement, he saves 8 hours per bid, i.e. 200 hours a year. If a credible website lifts the win rate to 20 %, he wins one extra contract a year, worth around GBP 400,000 of margin. A GBP 70,000 project plus GBP 18,000 of annual maintenance pays for itself with that first contract.
FAQ
Can we publish contract values for public projects?
Yes for awarded public contracts, whose values are published on Contracts Finder or Find a Tender. For private clients, get written consent or show a range (for example GBP 5 to 10 million).
How many projects do we need at launch?
Aim for 25 to 40 complete case studies. Fewer than 15 looks like a small firm; beyond 40, add them gradually, which GBP 1,000 to 2,000 monthly maintenance covers.
Is drone footage essential?
For civil engineering, infrastructure and large buildings, yes: an aerial view shows scale. The GBP 8,000 to 15,000 budget covers 8 to 15 sites, with flight permissions built into the plan.
Should we cover social value?
Yes. Public tenders in the UK now weight social value at 10 % or more under the Procurement Act 2023 regime. A dedicated page costs GBP 4,000 to 10,000 and feeds every bid.
How much lead time before a major tender?
At least 10 weeks. If your deadline is closer, we deliver the 15 strongest case studies in 6 weeks, then the rest in phase 2.
Let's scope your project. Send us your project list and certifications: we will price your portfolio website between GBP 35,000 and 75,000, drone footage optional, delivered in 10 to 14 weeks. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
