Retention Money Guarantee (Kenya)

A Retention Money Guarantee in Kenya binds a guarantor to satisfy another party's obligation if that party defaults.

In standard construction practice in Kenya, an employer withholds a retention percentage — typically between 5% and 10% of the value of certified work — from each interim payment certificate issued under the building or engineering contract. This cash retention fund is held by the employer as security against defective workmanship and incomplete work during the defects liability period following practical completion. The retention is conventionally released in two equal tranches: one half is released at the date of practical completion, and the balance is released at the end of the defects liability period once the contractor has rectified all notified defects to the employer's satisfaction.

A Retention Money Guarantee allows the contractor to receive the full certified value of interim payments — including the retention component that would otherwise be withheld — in exchange for providing the employer with a bank or surety guarantee for an equivalent amount. The guarantee assures the employer that, if the contractor fails to rectify defects during the defects liability period, the employer may call on the guarantee and recover the guaranteed amount directly from the issuing bank, without needing to pursue the contractor through litigation or arbitration.

The Public Procurement and Asset Disposal Act No. 33 of 2015, administered by the Public Procurement Regulatory Authority (PPRA), governs public sector construction contracts in Kenya. Standard Government of Kenya procurement contract forms issued by the PPRA contemplate the use of retention money guarantees in major public works contracts procured by National Government Ministries, State Corporations, and County Governments. The Kenya Institute of Supplies Management (KISM) recognises retention money guarantees as standard procurement instruments.

The Joint Building and Civil Engineering (JBCE) Conditions of Contract, widely used in Kenya for building works, and the NEC Engineering and Construction Contract (NEC ECC), increasingly adopted for major road and infrastructure projects by Kenya National Highways Authority (KeNHA), Kenya Urban Roads Authority (KURA), and Kenya Rural Roads Authority (KeRRA), both make specific provision for retention money guarantees as an alternative to cash retention. The guarantee must conform to the requirements of the relevant contract — particularly as to maximum amount, expiry date, calling conditions, partial demand rights, and governing law.

The Stamp Duty Act Cap. 480, administered by the Kenya Revenue Authority (KRA), applies to guarantee and bond instruments in Kenya. A bank guarantee operating as a deed of indemnity attracts stamp duty under the First Schedule to the Stamp Duty Act Cap. 480, and the applicable duty must be paid before the guarantee is presented to the beneficiary employer. An unstamped guarantee instrument is inadmissible as evidence in civil proceedings under Section 19 of the Stamp Duty Act Cap. 480 until the outstanding duty plus the prescribed penalty is paid. Stamping is conducted at KRA Stamp Duty offices or through the KRA iTax portal for eligible instruments.

A Retention Money Guarantee in Kenya is required across a wide range of construction, engineering, and supply contract scenarios where an employer holds cash retention and the contractor seeks to replace that withheld cash with a bank-backed or surety-backed guarantee instrument.

A Retention Money Guarantee is needed when a contractor working on a public sector infrastructure project — a road, dam, school, hospital, or government building — procured under the Public Procurement and Asset Disposal Act No. 33 of 2015 has accumulated a substantial cash retention fund and wishes to free up working capital by substituting a bank guarantee. Public employers in Kenya, including State Corporations, County Governments, and National Government Ministries contracting under standard PPRA forms, routinely accept Retention Money Guarantees from contractors operating through licensed commercial banks in Kenya.

A Retention Money Guarantee is required when a private sector employer — a property developer, mining company, hospitality group, or industrial plant operator — insists on cash retention under the building contract at tender stage, and the contractor either negotiates retention bond provisions into the contract at the outset or seeks to substitute the accumulated cash retention partway through the project after practical completion is certified.

A Retention Money Guarantee is needed when a contractor wishes to use a more favourable banking or bonding facility, using the guarantee as an off-balance-sheet financing instrument rather than having the employer hold cash. For small and medium enterprises (SMEs) and medium-sized contractors registered with the National Construction Authority (NCA) under the National Construction Authority Act No. 41 of 2011, cash retention withheld by employers over the course of long projects can represent a substantial portion of working capital. Replacing that cash with a Retention Money Guarantee from a commercial bank or an insurance company licensed by the Insurance Regulatory Authority (IRA) under the Insurance Act Cap. 487 frees that capital for deployment on other contracts.

A Retention Money Guarantee is required when the defects liability period under the building or engineering contract is extended — for example, because the employer has issued a defects notification list and the contractor has not completed all rectifications within the original defects liability period. The employer is entitled to require the guarantee to remain in force through the extended period, and the guarantee must be formally extended by an amendment instrument before the original expiry date to prevent a gap in cover.

A Retention Money Guarantee is also needed when a contractor subcontracts major works packages and the main contractor withholds retention from the subcontractor. The subcontractor may offer a back-to-back Retention Money Guarantee to release the retained funds, mirroring the arrangement between the main contractor and the employer.

Under the Central Bank of Kenya Act (Cap. 491), the Central Bank of Kenya (CBK) regulates banking. The Capital Markets Authority (CMA) regulates securities under the Capital Markets Act (Cap. 485A). Section 84 of the Bills of Exchange Act (Cap. 27) governs promissory notes. The Kenya Revenue Authority (KRA) administers tax obligations. The Microfinance Act No. 19 of 2006 regulates microfinance institutions. The Hire Purchase Act (Cap. 507) governs credit sale agreements.

A Kenya Retention Money Guarantee under the Law of Contract Act Cap. 23 must contain the following essential elements to be commercially effective, legally enforceable, and acceptable to Kenyan public and private sector employers.

Parties and Authorisation: Full legal name, registered address, and contact details of the guarantor (the issuing bank or licensed surety); full legal name and address of the employer (the beneficiary); and full legal name, address, and Business Registration Service (BRS) number of the principal (the contractor on whose behalf the guarantee is issued). Where the guarantor is a commercial bank, its CBK banking licence number should be stated to confirm it is a licensed institution under the Banking Act Cap. 488. Insurance companies issuing retention bonds in Kenya must be licensed by the Insurance Regulatory Authority (IRA) under the Insurance Act Cap. 487 and should quote their IRA licence number.

Underlying Contract Reference: The precise name, date, and contract reference number of the underlying building or engineering contract between the employer and the contractor. The Retention Money Guarantee is an accessory instrument tied to that specific contract, and must identify the contract with sufficient particularity that no doubt arises about which project the guarantee covers. Where the contract is a public procurement contract under the Public Procurement and Asset Disposal Act No. 33 of 2015, the PPRA tender number and contract award reference should also be stated.

Guarantee Amount: The maximum amount payable under the guarantee, expressed in Kenya Shillings (KES), representing the aggregate cash retention money that would otherwise have been withheld by the employer from interim payment certificates. The guarantee amount typically equals the retention percentage — commonly 5% or 10% — applied to the certified contract sum at the time of issue or at practical completion. The guarantee amount must be stated as a fixed maximum figure, not a formula.

On-Demand Character and Demand Conditions: A standard Retention Money Guarantee in Kenya is an autonomous on-demand instrument. The employer need only present a written demand certifying that the contractor has failed to rectify notified defects within the required period — no proof of actual loss, no court judgment, and no arbitration award is required before the guarantor must pay. This on-demand character reflects the autonomous nature of bank guarantees as recognised in Kenyan banking practice and mirrors international standby letter of credit principles. The demand conditions must state clearly what the demand letter must contain: the contract name, the specific breach alleged, and the amount demanded.

Expiry Date and Defects Liability Period Alignment: The guarantee expiry date must align with the end of the defects liability period under the underlying contract, plus a reasonable claims presentation window of at least 28 days. The defects liability period in Kenya building contracts is commonly 12 months from the date of practical completion, so the guarantee expiry is typically 12 months plus 28 days from practical completion. The guarantee must remain continuously valid throughout the defects liability period without any gap.

Partial Demands and Reduction: Whether the employer may make multiple partial demands up to the maximum guarantee amount, or whether the guarantee is callable only in full at once. Partial demand provisions protect the contractor against losing the full guarantee for a single minor defect, while still protecting the employer against cumulative defects. Where partial demands are permitted, the guarantee should state how the remaining available amount is calculated after each demand.

Extension Mechanism: A provision specifying the procedure for extending the guarantee before the expiry date — typically requiring a written request from the employer and the guarantor's agreement to issue an amendment instrument — to address extensions to the defects liability period under the building contract.

Governing Law, Jurisdiction, and Stamp Duty: The guarantee is governed by the laws of Kenya, including the Law of Contract Act Cap. 23, the Banking Act Cap. 488, and the Stamp Duty Act Cap. 480 administered by the Kenya Revenue Authority (KRA). Disputes are subject to the exclusive jurisdiction of the High Court of Kenya (Commercial Division). The guarantee instrument must be duly stamped under the Stamp Duty Act Cap. 480 before presentation to the employer beneficiary to confirm admissibility as evidence under Section 19 of the Act.
