What Is a Performance Bond and Why Kenyan Contractors Cannot Afford to Ignore It

When a contractor wins a tender in Kenya, the celebration is usually short-lived. What follows is a list of documents to produce before the contract can be signed. Near the top of that list, on almost every public sector and donor-funded project, is the performance bond.

Many contractors know the name. Fewer understand what the document actually does.

A performance bond is a financial guarantee issued by a bank or licensed insurer on behalf of a contractor, assuring the client that the contractor will fulfil their contractual obligations. If the contractor defaults, abandons the project, or fails to complete the works to the required standard, the client can call on the bond and receive compensation up to the bonded amount without having to go to court first. It is not insurance for the contractor. It is protection for the client, funded by the contractor.

In Kenya, performance bonds are a standard requirement in public procurement, donor-funded projects, and large-scale private sector developments. The Kenya National Highways Authority (KeNHA), the Kenya Rural Roads Authority (KeRRA) and most government ministries include a performance bond form as a mandatory tender document. The bond value is typically set at 10 percent of the contract sum, though some contracts specify higher percentages depending on the risk profile of the project.

There are two main types of performance bonds operating in Kenya's construction market. The first is an on-demand bond, also called an unconditional bond. This allows the client to call the bond and receive payment simply by making a written demand, without needing to prove that the contractor has actually defaulted. Kenyan courts have upheld on-demand bonds as enforceable on their face, meaning a contractor cannot easily stop a client from calling one unless there is clear evidence of fraud.

On-demand bonds are the preferred form in public and donor-funded projects precisely because of this enforceability. The second type is a conditional bond, which requires the client to demonstrate actual breach of contract before a payment is triggered. These are more common in private sector contracts and offer the contractor slightly more protection against unfair calls.

Performance bonds in Kenya are issued by two categories of institutions: commercial banks and licensed insurance companies. Banks typically issue bonds in the form of a bank guarantee, which is backed by the contractor's credit facility with the bank. Insurers issue surety bonds, which are underwritten against the contractor's financial standing and track record.

For contractors without strong banking relationships or sufficient credit limits, insurance-backed surety bonds can provide access to bonding that a bank might decline. Providers active in this space include commercial banks such as KCB, Equity Bank, Co-operative Bank and Stanbic Bank, as well as surety and financial institutions including Discount Capital, Recolte and Sidian Bank.

The cost of obtaining a performance bond varies. Bank guarantees typically attract a facility fee of between one and two percent of the bond value annually. Insurance-backed surety bonds are similarly priced, though rates depend on the contractor's financial profile, contract value and project duration.

The bond remains in force for the duration of the contract and is typically released once the engineer or architect issues the practical completion certificate. Some contracts also require a separate defects liability bond to cover the period after completion during which the contractor is responsible for rectifying faults.

One point contractors frequently miss is the renewal obligation. If a project overruns its original programme, the performance bond expiry date may fall before practical completion. A bond that has lapsed is effectively no bond at all. The client can claim the contractor is in breach of the bonding requirement, which itself can constitute a default under the contract. Contractors should track bond expiry dates as carefully as they track any other contractual deadline and apply for extensions proactively when delays are anticipated.

For contractors bidding on their first formal tenders, securing a performance bond is also an early test of financial credibility. A bank or insurer that agrees to back a bond is effectively vouching for the contractor's ability to deliver. Building that relationship early, before the pressure of a tender deadline, is one of the more practical steps any growing construction business in Kenya can take.
