How to Choose a Verified Contractor in Kenya

Introduction

"Verified" means different things depending on who's saying it. Before hiring any construction contractor in Kenya — whether through a platform or directly — here's what's actually worth checking yourself.

Registration and licensing

For general building contractors, checking National Construction Authority (NCA) registration is standard practice — this confirms the contractor is legally permitted to operate at the scale of your project (NCA registration tiers correspond to project value ranges). You can check a contractor's registration status yourself using the NCA's Search Registered Contractors tool — search by company name or registration number to confirm license and certificate status directly, rather than relying on the contractor's own claim. For architects, structural engineers, and quantity surveyors specifically, the relevant checks are with their own professional bodies rather than NCA. This is general industry practice in Kenya, not specific to any one platform.

References and past work

Ask for at least two references from projects of similar scale to yours, not just testimonials already curated for a website or profile — a contractor willing to connect you directly with a past client is signaling more confidence than one who only offers pre-written quotes.

What questions should you ask a contractor before hiring them?

Ask for their NCA registration number (and verify it independently, not just take their word for it), request references from two comparable-scale projects, and ask directly how disputes or delays were handled on a past job — the answer to that last question often reveals more than a portfolio does.

Red flags to watch for

A contractor unwilling to provide a registration number, one who pressures you to skip a written contract, or one whose quote is dramatically below every other quote you collected (see how to compare multiple quotes) are all worth pausing on before proceeding.
