Why registration matters to you
Registration is not a badge. It is your recourse
The National Construction Authority registers contractors and regulates construction works in Kenya. For a client, the practical significance is simple: a registered contractor exists in a system that can be checked, that records who they are, and that provides somewhere to go when something goes seriously wrong. An unregistered one does not.
It matters most at exactly the moment you least want to be dealing with it — a dispute, a structural failure, a contractor who has stopped attending site. At that point the difference between a registered firm and a man with a lorry is the difference between a process and a problem.
The honest caveat is that registration is a floor, not a guarantee of quality. It tells you a contractor is accountable within a framework. It does not tell you they will manage your budget well or supervise your reinforcement properly — which is why the rest of this page is about the things registration does not cover.
What registration does and does not protect you from
Five risks a registration number alone will not remove
Check the registration. Then check these.
A price with no measured basis
Registration says nothing about how a contractor arrives at a figure. A measured bill of quantities does, and it is the document that makes a budget defensible.
No qualified supervision on site
Whether someone technically competent is present when reinforcement goes down is a matter of how the contractor staffs the job, not of how they are registered.
Work that exceeds the registration category
Registration categories carry limits on the value and type of work. Verifying that a contractor's category covers your project is part of checking the registration, not separate from it.
Subcontracting to unregistered parties
A registered main contractor can still put unregistered subcontractors on your site. Ask who is actually doing the work.
Missing statutory approvals
NCA registration is one requirement among several. County approval and, where applicable, a NEMA licence are separate obligations with their own consequences.
What we do
The work itself, which is what you are actually buying
Five of our seven service lines, available together or separately.
Building Construction
Residential, commercial and mixed-use construction from substructure through superstructure to finishes and external works.
Architectural & Structural Design
Layouts and reinforced concrete or steel design, produced in-house rather than bought in from a consultant you never meet.
Bill of Quantities
Measured quantities so your budget is a document rather than a quotation, and variations have a basis.
Project Management
Programme, procurement, cost control and staged quality inspections as the client's representative.
Environmental Impact Assessment
The environmental documentation a development needs, handled as part of the same appointment rather than sent elsewhere.
How to check any contractor
Six things to verify before you sign
Use this on us and on everyone else you are considering.
Ask for the registration details
A registered contractor can give you their details without hesitation. Hesitation is itself an answer.
Verify them with the Authority
Check the details you were given directly with the National Construction Authority rather than taking a certificate at face value.
Check the category covers your project
Registration categories carry limits. Confirm the contractor's category permits work of your value and type.
Ask who will actually be on site
Who supervises, what their qualification is, and how often they attend. Get it in writing.
Insist on a measured bill
A price without a bill of quantities cannot be compared, checked, or used to settle a variation later.
Confirm the other approvals
County approval and any environmental licence are separate requirements. Establish who is responsible for each.
Why TopHall
What we bring beyond compliance
Registration gets a contractor onto the list. These are the reasons to choose from it.
Engineers, not just builders
Structural, environmental and water engineering are our own disciplines. The technical decisions on your site are made by people qualified to make them.
Measured pricing as standard
Quantity surveying is one of our service lines, so budgets come from measured quantities and variations are priced against them in writing.
Statutory work handled in-house
Environmental impact assessment and management planning are services we sell, so compliance is programmed rather than referred elsewhere.
Inspection before work is covered
Setting out, reinforcement and pours checked and signed off while they can still be corrected.
A traceable company

Before you call
What clients ask about contractor registration
Is TopHall Group registered with the National Construction Authority?
Yes. Ask us and we will give you our registration details in writing so you can verify them directly with the Authority rather than relying on our word or on a certificate image. We would encourage you to do the same with every contractor you are considering — it takes a few minutes and it is the single easiest piece of due diligence available to you.
What happens if I use an unregistered contractor?
Practically, you lose your recourse. Registration places a contractor inside a regulatory framework with a record of who they are and a route for complaints and enforcement. Without it, a dispute, an abandonment or a structural failure leaves you with a civil claim against someone who may be difficult to locate. There are also compliance consequences for the works themselves, which can affect approvals and financing.
Does registration category matter for my project?
Yes. Registration categories carry limits on the value and type of works a contractor may undertake, so a category appropriate for a boundary wall is not appropriate for an apartment block. When you verify a contractor's registration, confirm that their category covers the project you are asking them to do — it is a common gap and it is entirely checkable in advance.
