Bid Security and Tender Security in Kenya: Complete Guide (2026)
Everything Kenyan SMEs need to know about bid security — what it is, how much it costs, where to get it, and how AGPO applicants can get reduced requirements.
Bid security (also called a tender bond or bid bond) is a guarantee you submit with your tender document assuring the procuring entity you are serious about your bid. It is essentially a promise: if you win this tender and then withdraw or fail to sign the contract, the entity can claim this amount. Kenya's procurement regulations set a ceiling of 2% of the estimated contract value — so a KES 10,000,000 tender can require up to KES 200,000 in bid security.
Accepted forms of bid security in Kenya include bank guarantees (issued by licensed commercial banks, cost 0.5-2% of guarantee value per annum, processing 1-5 business days), insurance bonds (issued by licensed insurance companies via brokers, cost 1-3% flat fee, processing 1-3 business days), and cash deposits (full amount deposited, tied up until award). For most SMEs, insurance bonds are the most accessible route — lower fees, faster processing, and no capital lockup.
AGPO-registered businesses have a significant advantage: PPADA Section 159(3) allows Youth, Women, and PWD enterprises to be exempt from or have their bid security requirements reduced. Many tender documents specify 'AGPO-registered bidders are exempt from bid security.' Check Section 4 (Evaluation Criteria) and Section 6 (Instructions to Bidders) specifically for this language — it is one of the most underutilised advantages of AGPO registration.
Common bid security mistakes that get Kenyan SMEs disqualified: wrong validity period (the guarantee must remain valid beyond the tender validity period), wrong currency, wrong amount even by KES 1, conditional guarantees (must be unconditional and irrevocable), submitting a photocopy when an original is required, wrong beneficiary name (must match the exact procuring entity name in the tender document), and not keeping a certified copy for your records.
Once you win a tender, bid security is replaced by performance security — typically 5-10% of contract value, compared to bid security's 2% maximum. Plan your finances accordingly: the cost of winning a large tender includes significant guarantee fees. Apply for bid security at least a week before the bid deadline for bank guarantees, or 2-3 days before for insurance bonds.
