10 Common Forms of Construction Fraud in Kenya – And How to Avoid Them 

Building your dream home or investing in a commercial property is a significant financial commitment. Unfortunately, the construction industry in Kenya has earned a reputation for being riddled with dishonest players. Studies show that developers lose more than 30% of their project expenditure to swindlers and fraudulent practices.

While there are many genuine and reputable construction professionals in Kenya, the unfortunate reality is that dishonest individuals often outnumber the honest ones. The result? Poor workmanship, inflated costs, delayed projects, and in some cases, total abandonment.

The good news is that you don’t have to be a victim. By understanding the most common forms of construction fraud, you can protect your investment and ensure your project is completed to the highest standards.

In this comprehensive guide, we reveal the 10 most common construction fraud schemes in Kenya and provide practical tips on how to safeguard your project.

1. Inflated Payment Applications

The Scam: Your contractor, supplier, or subcontractor bills you for materials or services at rates significantly higher than the prevailing market costs. Sometimes, the trick is more subtle—contractors invoice you separately for equipment hire that was already included in the original contract.

How to Protect Yourself:

  • Engage a reputable construction project manager to review all contract bills and quantities

  • Ensure your project manager conducts market comparisons before approving any payment

  • Have all payment applications independently verified before release

2. Material Swapping and Omission

The Scam: Contractors and suppliers know that most developers cannot tell the difference between various grades of construction materials. They may substitute high-grade materials with cheaper, low-grade alternatives while charging you for the premium version.

For example, aggregates account for 65% to 75% of concrete volume. The grade of aggregate determines concrete strength, durability, and water absorption. Yet many site workers acquire cheaper aggregates to cut costs—at the expense of your building’s structural integrity.

How to Protect Yourself:

  • Insist on material testing and quality assurance at every stage

  • Engage a project manager to verify that delivered materials match specifications

  • Request certificates of compliance from suppliers

3. Charging Outside the Contract Bills

The Scam: Contractors may bill you for work or materials not included in the original contract bills. Without a detailed program of works, you become vulnerable to extra charges for activities that were either unnecessary or already covered.

How to Protect Yourself:

  • Ensure your contract includes a comprehensive Bill of Quantities (BoQ)

  • Require a detailed program of works before construction begins

  • Reject incomplete documents—and withhold up to 50% of payments until the contractor complies

4. Falsifying Variations

The Scam: During construction, changes (variations) often occur due to site conditions. Dishonest contractors may falsify variation orders to inflate costs, adding unnecessary items or overestimating quantities.

For instance, if foundation depth increases, the contractor might exaggerate the additional labor, concrete, and steel required—leaving you with no choice but to trust their numbers.

How to Protect Yourself:

  • Have a quantity surveyor independently assess all variation orders

  • Balance variations by ensuring additions are offset by subtractions

  • Document every variation and ensure all consultants sign off

5. Downgrading the Construction Labor Force

The Scam: Many developers only interact with the main contractor and never review the qualifications of the site workforce. Contractors exploit this by hiring cheap, unskilled laborers instead of skilled craftsmen. This allows them to convert low bids into high profits—while delivering poor workmanship.

How to Protect Yourself:

  • Request CVs and credentials of key site personnel

  • Conduct random site visits to observe work quality

  • Insist that your contract specifies the minimum skill levels required

6. Evading Construction Liabilities

The Scam: Unlicensed contractors and unqualified consultants often operate without liability insurance. If an accident occurs or structural failure happens, they simply disappear—leaving you to bear the full cost of damages.

Licensed professionals, on the other hand, carry insurance against site accidents, structural failure, fire, floods, and other risks.

How to Protect Yourself:

  • Only engage NCA-registered contractors and licensed consultants

  • Verify that your contractor has valid insurance policies (CAR insurance, WIBA, public liability)

  • Ensure the contract indemnifies you against all potential liabilities

7. Unbinding Upfront Payments

The Scam: Contractors often request an upfront “deposit” before starting work. While this is common practice, it becomes dangerous when there is no binding contract in place. Many contractors have collected deposits and vanished, leaving clients to start over at an additional cost.

Even when contractors stay, upfront payments can reduce their incentive to deliver quality work.

How to Protect Yourself:

  • Have a legally binding contract drafted before making any payment

  • Reject upfront payments—instead, remit funds after interim certificates are issued

  • Request a contract bond as compensation guarantee

  • For smaller projects, consider using an escrow account

8. Avoiding Quality Testing and Assurance

The Scam: Contractors may try to convince you to skip critical quality tests to save time and money. They may show you past projects or offer complimentary works to build trust—then deliver substandard work.

Critical tests that are often skipped include:

  • Compressive strength tests (concrete)

  • Slump tests

  • Water absorption tests

  • Rebound hammer tests

  • Vibration tests

How to Protect Yourself:

  • Insist on all standard quality tests being conducted

  • Have results documented and signed off by your project manager

  • Never accept verbal assurances—demand written test reports

9. Underestimating Repair Works

The Scam: A contractor bids for a repair job at a seemingly low price. After demolitions begin, they “discover” that the problem is much bigger than anticipated—and request a revision of the contract sum. In some cases, they use scare tactics to pressure you into approving additional costs.

How to Protect Yourself:

  • Ensure the contract explicitly states that additional works may arise

  • Split repair projects into two phases: demolition and rebuilding

  • Complete the demolition phase before bidding for the repair works

10. Prolonging the Project Period

The Scam: Dishonest contractors may deliberately delay your project to juggle multiple jobs simultaneously. They pull resources off your site to prioritize other “better-paying” projects, then offer excuses—delayed materials, subcontractor issues, or personal problems.

How to Protect Yourself:

  • Include penalty clauses for late completion in your contract

  • Monitor progress against the program of works

  • If delays persist, exercise your right to terminate the contract
