The verdict in three sentences
For a borehole drilling contractor in Nairobi bidding on tenders from NGOs, county governments and donor-funded projects, an effective website costs KES 450,000 to 800,000 (about USD 3,500 to 6,200) and takes 6 weeks. Roughly 50% of contracts go through donors whose procurement officers check the website before shortlisting: geolocated project references and certifications matter more than design. Every page should weigh under 1 MB so it opens on 3G, in Nairobi as on a site in Turkana or Kitui.
The pages that win contracts
A water and sanitation programme officer checks three things: the company really exists, it has drilled comparable boreholes, and it has the rigs and staff. The website must answer those three questions in under two minutes.
| Page | Expected content | 2026 budget | What the donor checks |
|---|---|---|---|
| Home and key figures | Boreholes completed, metres drilled, counties covered | KES 60,000 to 100,000 | Real size and experience |
| Geolocated project map | 50 to 200 sites, depth, yield, client, photos | KES 115,000 to 210,000 | Experience on similar works |
| Equipment and capacity | Drilling rigs, compressors, trucks, team | KES 50,000 to 90,000 | Ability to deliver the lot |
| Certifications and documents | NCA registration, WRA licence, tax compliance, completion certificates in PDF | KES 40,000 to 75,000 | Administrative compliance |
| Tender enquiry form | Lot, county, deadline, file upload | KES 60,000 to 110,000 | Responsiveness |
| Service pages | Hydrogeological survey, drilling, solar pumping, rehabilitation | KES 75,000 to 125,000 | Fit with the terms of reference |
| 3G optimisation and local SEO | WebP images, pages under 1 MB, Google listing | KES 50,000 to 90,000 | Fast access from the field |
| Total | KES 450,000 to 800,000 | Delivered in 6 weeks |
The bottom of the range covers 50 references entered by the company itself. The top includes entering 150 to 200 references, a Swahili summary for county audiences and a photo shoot on two sites.
Light website, credible website: the technical choices
Mobile coverage in Kenya remains uneven outside the main towns, and an engineer checking the website from a drilling site gives up after 6 to 8 seconds of loading.
| Technical choice | Common heavy version | Recommended version | Measured effect |
|---|---|---|---|
| Home page weight | 4 to 6 MB | Under 1 MB | 3G load time cut by about 4 |
| Site photos | 3 MB JPEG | 80 to 150 KB WebP | Gallery readable outside town |
| Project map | Full Google map loaded by default | Light map loaded on click | 700 KB saved |
| PDF documents | 8 MB scans | Compressed PDFs under 1 MB | Downloadable on 3G |
| Hosting | Slow shared server | Hosting with CDN | Response time under 500 ms |
| Languages | English only | English + Swahili summary | Better reach with county officials |
Hosting and maintenance run around KES 7,000 to 15,000 a month, depending on how often new references are added and how documents are backed up.
Mini case study
James, managing director of a drilling contractor in Nairobi, bids on about 24 tenders a year and wins 4, with an average margin of KES 1,500,000 per contract. He invests KES 620,000 in a website with 120 geolocated references. If the site lifts his win rate from 4 to 5 contracts a year, so one more contract, the extra margin reaches KES 1,500,000. The website pays for itself on that first additional contract, about 2.4 times the investment in year one.

FAQ
How many references should we publish?
Aim for at least 30 to 50 documented sites with county, depth, yield and client. Below 20, a donor may doubt the company's real experience.
Can we publish NGO references without their consent?
Written consent is better, especially for logo use. Otherwise, write "international NGO" plus the county, without a logo, which remains credible for 80% of evaluators.
Should the site be translated into French?
Only if you bid regionally in francophone countries or for French-speaking donors. The extra cost is KES 75,000 to 125,000 for the key pages.
How do we add new sites after delivery?
A simple back office lets you add a reference with photos and GPS coordinates in 10 minutes. A 2-hour training session is included at handover.
Does the tender form replace official submission?
No. It handles restricted consultations and quotation requests. The official bid is still submitted through the client's procurement procedure.
