Before you hand over a single shilling, ask one question that can spare you the heartbreak so many diaspora investors have endured: is this an NCA registered contractor, and are they legitimate?
In Kenya, every contractor performing construction work must be registered with the National Construction Authority (NCA). It is not optional. Yet countless unregistered operators and outright fraudsters still take on projects — collecting deposits, cutting corners, and leaving behind substandard structures or abandoned sites. The good news is that verifying a contractor's legitimacy takes just a few minutes, and recognising the warning signs of a rogue operator can protect your entire investment.
Why NCA registration matters
The NCA exists to regulate and build the capacity of Kenya's construction industry — and, crucially, to ensure that the people building your home or investment property are competent, accountable and legitimate. A properly registered contractor:
Has been vetted for technical capacity, financial standing and the right personnel.
Is officially permitted to carry out work up to a defined value and complexity.
Can be held accountable through a formal, traceable regulatory body.
An unregistered contractor offers none of this. If they vanish with your money or deliver dangerous work, you have little recourse — because, in the eyes of the law, they should never have been building in the first place.
Understanding NCA categories: NCA 1 to NCA 8
The NCA grades contractors into eight categories based on their capacity:
NCA 1 — the highest category, for the largest and highest-value projects.
NCA 8 — the entry-level category, for the smallest works.
Contractors are also registered under specific classes of work — such as building, civil (roads and water), electrical and mechanical.
Why this matters to you: A contractor registered as NCA 8 for small works is neither qualified nor legally permitted to undertake a large, complex development. Always confirm that the contractor's category and class match your project's scale and type. A contractor registered for minor works taking on a major build is a serious red flag.
How to verify an NCA registered contractor: step by step
Option 1: Search the NCA registered contractors database
Go to the official NCA website: www.nca.go.ke.
Navigate to the Contractors section and select Search Registered Contractors.
Enter the contractor's company name or registration number.
Review the results.
The results show:
Registration number
Category (NCA 1–8)
County
Licence status — is it active and valid?
Certificate status
Option 2: Verify the certificate directly
The NCA portal includes a Verify Certificate tool. Enter the contractor's registration number to confirm that their certificate and licence are genuine and current, or scan the QR code on the certificate to view all the contractor's details.
What to confirm
The contractor appears in the database. If they don't, that's an immediate stop sign.
Their licence status is active — not expired or suspended. Registration must be renewed, and a lapsed licence means they are not currently permitted to work.
Their category and class match your project.
The registered company name matches the name on their quotes, contracts and bank details exactly.
Diaspora tip: Don't take a contractor's word — or even a photo of a certificate — as proof. Certificates can be forged or expired. Always verify directly on the NCA portal yourself, or ask a trusted, independent person in Kenya to verify on your behalf.
Eight red flags of a rogue contractor
NCA registration is the baseline — but even some registered contractors behave badly, and many fraudsters operate entirely outside the system. Watch for these warning signs:
1. They can't (or won't) prove their NCA registration
A legitimate contractor will readily share their registration number and welcome verification. Evasiveness, excuses, or "I'll send it later" are major red flags.
2. They require large upfront payments
This is the classic fraud pattern. A rogue contractor seeks as much money as possible before any work begins — then disappears or stalls. Legitimate contractors follow a payment schedule tied to progress, not a large deposit upfront.
3. The quote seems suspiciously cheap
If one quote is dramatically lower than the others, be very cautious. It often signals that corners will be cut, inferior materials will be used, or there is a plan to inflate costs later with "unexpected" extras.
4. No written contract, or vague terms
A refusal to sign a detailed, written contract — or one that's vague on scope, timeline, payments and specifications — leaves you exposed. Professionals put everything in writing.
5. No physical address or verifiable track record
Rogue operators are hard to pin down. No registered office, no verifiable past projects, and no references you can actually contact — these are signs you're dealing with a ghost.
6. No professional team or documentation
Legitimate projects involve architects, engineers and a quantity surveyor, along with proper drawings, a bill of quantities and approvals. A contractor who dismisses these requirements as unnecessary is dangerous.
7. Pressure and urgency
"Pay today, or you lose the price." "We must start immediately." High-pressure tactics are meant to stop you from doing your due diligence. Walk away from anyone who won't let you take the time to verify.
8. Reluctance to use escrow or milestone payments
A rogue contractor hates any system that ties payment to verified work — because that's exactly what prevents them from taking your money and running. An honest contractor welcomes it.
Your diaspora due-diligence checklist
Before committing to any contractor, confirm:
Verified on the NCA portal — active licence, correct category and class
Company name matches across certificate, contracts and bank details
Written contract with clear scope, schedule, specifications and payment terms
References from past clients
A physical office
A proper professional team (architect, engineer, quantity surveyor) and approved drawings
Payment tied to milestones — never a large sum upfront
Willingness to work through an escrow arrangement
If a contractor fails to meet even one or two of these criteria, pause and investigate before you part with any money.
