What is L1 (lowest bidder)? How government tenders pick a winner
L1 means the lowest-priced eligible bid. Here's how the winner is chosen — and when lowest doesn't automatically win.

What L1 means
- L1 (Lowest-1) is the bidder who quotes the lowest evaluated price among all technically-qualified bids.
- Most government works and supply tenders are awarded to L1 — the lowest eligible price wins.
- L2, L3 and so on are the next-lowest; they only matter if L1 backs out or is disqualified.
How the evaluation works
- Bids are first checked for eligibility and technical compliance — non-compliant bids are rejected before price is even opened.
- Only technically-qualified bids reach the financial stage. Among those, the lowest is L1.
- The 'price' is usually the total evaluated cost — base price plus taxes and any loadings the tender specifies.
When lowest doesn't automatically win
- Quality-cum-Cost (QCBS) tenders — common for consultancy — score technical quality AND price together; the best combined score wins, not just the cheapest.
- Some tenders question 'abnormally low' bids that look unviable — you may be asked to justify your price.
- Always read the 'evaluation criteria' section; it tells you exactly how the winner is chosen.
Price to win without losing money
- Don't undercut blindly — quote below your real cost and you win a loss-making contract.
- Cost every BOQ line, add overhead and a thin but real margin, then check if you're competitive.
