If you're planning a construction project in Kenya, chances are you’ve heard about NCA categories. But do you really know what they mean—or why they’re worth your attention?
Let’s break it down simply and practically.
What is the NCA?
The National Construction Authority (NCA) is the government body that regulates the construction industry in Kenya. One of its key roles is registering and classifying contractors.
NCA doesn’t just list contractors. It ranks them based on their technical capacity, financial strength, equipment, and experience.
What Are NCA Categories?
There are eight categories: NCA1 is the highest, and NCA8 is the entry-level. These categories apply to three main classes of construction:
- Building Works
- Roads and Civil Works
- Water Works
Each category defines the project size and complexity a contractor is allowed to handle.
What Do These Categories Mean?
Here’s a quick breakdown:
| Category | Estimated Contract Value (KES) | Typical Projects |
|---|---|---|
| NCA1 | 1 billion and above | Highways, dams, airports |
| NCA2 | 500 million – 1 billion | Hospitals, shopping malls |
| NCA3 | 200 million – 500 million | Schools, apartments, factories |
| NCA4 | 100 million – 200 million | Banks, office blocks |
| NCA5 | 50 million – 100 million | Mid-sized residential projects |
| NCA6 | 20 million – 50 million | Homes, commercial fit-outs |
| NCA7 | 10 million – 20 million | Minor buildings, renovations |
| NCA8 | Up to 10 million | Small house projects, maintenance |

Why Should You Care?
Hiring a contractor outside their NCA category can expose your project to serious risks.
Here’s why it matters:
1. Legal Protection
Only registered contractors can legally take on building works. If your contractor isn’t compliant, your site could be shut down or blacklisted.
Would you risk your investment over a missing license?
2. Project Safety
Higher NCA categories often have:
- Qualified staff
- Proper insurance
- Safer working conditions
A low-category contractor working on a high-value project may lack the capacity to ensure safety and quality.
3. Workmanship and Quality
Categories reflect past performance and capability. For example, a contractor in NCA4 has likely completed larger and more complex projects than one in NCA7.
Would you trust a small maintenance firm to build a multi-storey commercial block?
4. Avoiding Delays and Budget Blowouts
Contractors with the right category know how to manage materials, workers, and time. If your project requires permits and reports, they’ve dealt with that before.
Those without the experience often struggle to coordinate teams, causing delays, poor planning, or inflated costs.
How to Check a Contractor’s NCA Status
It’s fast and free.
- Go to the NCA Contractor Search Tool.
- Enter the registration number.
- Check their registered categories and status.
Don’t rely on verbal confirmation. Always cross-check.
Does a Higher Category Mean Better Work?
Not always. A higher category shows capacity, not guaranteed quality.
You still need to:
- Review their previous projects
- Visit their office
- Speak to past clients
- Ask about their team (foremen, project managers, quantity surveyors)
A contractor might be NCA3 but still deliver poor work. Others in NCA6 may be more dedicated and transparent. Category is just one factor—use it alongside other checks.
What If You Have a Small Project?
If you're building a single home or doing renovations, you don’t need an NCA1 contractor. You’ll likely be fine with NCA6 to NCA8, depending on your project size.
Just make sure they’re registered, insured, and trackable.
Should the Client or Contractor Handle NCA Registration?
Contractors are required by law to be registered. If your contractor tells you they’re working “under another company’s license,” that’s a red flag.
Ask for proof:
- Registration certificate
- Valid annual practicing license
- Their name on the NCA search list
It’s your right to know who’s working on your property.
What About Specialized Works?
Some works (like electrical, plumbing, or HVAC) may not fall under NCA but require separate licenses (e.g., EPRA for electrical). Ask your contractor to clarify who handles those parts—and if they’re certified.
Final Thought
If you're spending millions on a project, take five minutes to check your contractor’s NCA category.
Would you let an unlicensed driver take you across the country?
Then don’t let an unlicensed builder handle your dream project.
Your structure depends on more than concrete. It starts with choosing the right people.
