How Tender Evaluation Works in Kenya: What Government Evaluators Look For in 2026
Most Kenyan suppliers lose tenders because they don't understand how evaluators score bids. This guide breaks down the full evaluation process — technical scoring, financial evaluation, and common mistakes that knock out strong bids.
Kenya government tender evaluation follows a structured three-stage process under PPADA 2015: (1) Opening stage — all bids opened publicly, names and prices recorded; (2) Preliminary evaluation — compliance check, pass/fail; (3) Detailed evaluation — technical scoring for qualifying bids, financial comparison among technically qualified bidders. The award recommendation goes to the technically qualified bidder with the lowest evaluated price, subject to negotiations on exceptional grounds. Understanding this sequence helps you prioritise where to invest your bid preparation effort.
At the bid opening stage, all submitted bids are opened publicly in the presence of bidders or their representatives. Bidders are legally entitled to attend the public opening and record the prices submitted by competitors. This is valuable market intelligence — attending bid openings lets you calibrate your pricing for future bids in similar categories. The opening stage reveals who else is bidding and at what price range, even if you don't win the current tender.
Technical evaluators are typically a committee of 3-5 internal staff with relevant expertise. They score each bid independently and then reconcile scores. The evaluation criteria are fixed — they cannot add new criteria after opening, and they cannot change the weighting. This is why bidders who read the entire tender document and understand the evaluation matrix have a structural advantage. Every criterion in the scoring table is an instruction on what your technical proposal must address. Missing a criterion loses you points.
The most common technical evaluation mistakes: (1) Submitting the same generic proposal for every tender — evaluators can tell; (2) Referring to company experience without providing evidence — claims without supporting documents score zero; (3) Naming staff who don't have the qualifications specified; (4) Describing a generic methodology rather than a project-specific approach; (5) Underestimating the importance of the work plan — a clear, realistic timeline with milestones scores significantly better than vague descriptions.
Financial evaluation methodology varies by tender type. For straightforward goods supply, it is simply the lowest offered price. For services, evaluators may use the Quality and Cost Based Selection (QCBS) method — combining a weighted technical score (e.g., 70%) with a weighted financial score (e.g., 30%). Under QCBS, a higher-priced bid that scores 90 on technical can beat a lower-priced bid that scores 70 on technical, depending on the weighting. Read the specific evaluation methodology in your tender document before finalising your price strategy. TenderAI helps you analyse tender evaluation criteria to structure your bid for maximum scoring.
