Business Name Registration in Kenya: Step-by-Step Guide
How to choose, search, and register a business name in Kenya through eCitizen — including what names are allowed, how reservation works, and how to handle conflicts.
Business name registration in Kenya is the legal process of registering a trading name for a sole proprietorship or partnership under the Registration of Business Names Act. Total cost is KES 950, total time is 4–6 business days, and the entire process happens online through eCitizen. This guide walks you through choosing a name that will be approved, conducting the search, reserving it, and completing registration without delays.
Business Name Registration vs Company Registration
These terms are often confused. Here's the difference:
- Business name registration: Registers a trading name for a sole proprietorship or partnership. The business is not a separate legal entity. Cheap (KES 950), fast (4–6 days).
- Company registration: Specifically refers to registering a limited liability company — a separate legal entity with shareholders and directors. More expensive (KES 10,000–15,000), slower (5–10 days).
Both are managed through the Business Registration Service (BRS) on eCitizen, but they use different application paths. For a full comparison of all business types, see our complete company registration pillar guide.
Choosing a Business Name That Will Be Approved
Most rejected applications fail at the name search stage. Avoid wasted KES 150 fees by following these rules:
What works
- Descriptive names: "Mwangi Plumbing Services", "Kibera Mama Cooperative Stores"
- Owner-named with descriptor: "Wanjiku Catering Enterprises"
- Made-up names with descriptor: "Vibez Boutique", "Tamasha Events"
- Place + activity: "Westlands Coffee Roasters", "Nairobi Cycle Hub"
- Adding suffixes for differentiation: "Solutions", "Ventures", "Holdings", "Group", "Enterprises"
What gets rejected
- Restricted words: "Bank", "Sacco", "Insurance", "Trust", "Government", "Ministry", "National", "Royal", "Imperial", "President", "Federal" — these require special clearances
- Identical or near-identical names: "Safaricomm Solutions" will be rejected for sounding like Safaricom
- Misleading names: "Tax Refund Office" implies KRA association
- Offensive or obscene words: Self-explanatory
- Names suggesting royal/state patronage: "Kenya National Builders" without authorization
- Pure individual names without descriptors: "John Mwangi" — needs at least "Enterprises" or similar
Best practice: prepare 3–5 name options
Even a well-chosen name might conflict with something on the register. Always have backups ready ranked by preference. The search costs KES 150 per attempt, so each rejected name costs you both time and money.
How to Conduct the Name Search on eCitizen
Step 1: Log into eCitizen
Go to accounts.ecitizen.go.ke and sign in. From the dashboard, click "Business Registration Service".
Step 2: Click "Make Application" → "Name Search"
Choose "Name Search" from the BRS application options. Enter your top-choice business name. The form lets you submit up to three name options ranked by preference for one fee — useful if you suspect your first might be taken.
Step 3: Pay KES 150
Payment is processed instantly via M-Pesa (recommended), Visa, or Mastercard. Save the receipt — you may need to reference it.
Step 4: Wait 24 Hours for Result
The Registrar checks your proposed names against the active register. You'll receive an email with one of these outcomes:
- Approved: Move on to registration
- Approved with conditions: Slight change required (e.g., add "Ltd" or remove a word)
- Rejected: Try another name
Name Reservation: How It Works
When your name is approved, eCitizen automatically reserves it for you for 30 days. During this window, you must complete the full business registration — otherwise the name returns to the available pool and someone else can take it.
For sole proprietorships and partnerships, there is no separate reservation fee — it's included in the search cost. For limited companies, an additional reservation fee may apply depending on the share capital structure.
Completing the Business Registration
Once your name is approved and reserved, you complete the registration application. The form asks for:
- Business type: Sole proprietorship or partnership
- Owner / partner details: National ID, KRA PIN, photo, contact info for each person
- Nature of business: Specific activity codes (e.g., "Retail trade in clothing and apparel")
- Registered address: Physical building, street, town
- Date of commencement: When you plan to start operating
Pay the KES 800 registration fee. Submit. Approval typically arrives within 3–5 business days. Total elapsed time from name search start to certificate in hand: 4–6 business days.
What If Your Name Is Already Taken?
You have three options:
- Modify the name: Add a descriptor ("Solutions", "Ventures", "Group") or geographic anchor ("Nairobi", "Mombasa") to differentiate
- Choose a backup name: Submit your second-choice option (this is why having 3–5 ready saves time)
- Check if the existing name is dormant: If the registered name hasn't been active for years, you can apply for it to be struck off — but this is a slow legal process taking 3–6 months
Updating a Registered Business Name
After registration, you can update certain details by submitting an amendment through eCitizen:
- Address change: KES 200 fee
- Adding or removing partners: KES 500 fee
- Change of nature of business: KES 200 fee
- Change of name: Requires a fresh name search and re-registration; costs KES 950 essentially
What to Do After Getting Your Certificate
- Open a business bank account using your certificate, KRA PIN, and ID
- Apply for a Single Business Permit from your county government (mandatory before operating)
- Register on iTax for the right tax regime: Turnover Tax (1%) for sub-KES 5M revenue, or graduated income tax otherwise
- Build your online presence: Get a domain matching your business name (e.g., yourbusinessname.co.ke) and a professional website

Trademark Protection vs Business Name Registration
Business name registration on eCitizen does not protect your name as a trademark. To prevent others from using a similar mark across Kenya (or East Africa), you need to file a trademark with the Kenya Industrial Property Institute (KIPI). Trademark registration costs KES 4,000–10,000 per class and takes 6–12 months. It's worth doing for businesses building a brand identity.
Frequently Asked Questions
What is business name registration in Kenya?+
Business name registration is the process of formally registering a trading name under the Registration of Business Names Act. It applies to sole proprietorships and partnerships — businesses that operate under a name different from the owner's personal name. The certificate proves you have the legal right to trade under that name.
Is business name registration the same as company registration?+
No. Business name registration creates a registered name for a sole proprietorship or partnership — but the business is not a separate legal entity. Company registration (specifically a limited company) creates a distinct legal entity separate from its owners. Both are done through eCitizen but use different application paths.
How much does business name registration cost in Kenya?+
KES 950 total: KES 150 for the name search and KES 800 for the registration. There is no separate name reservation fee for sole proprietorships and partnerships — the search fee includes the reservation.
Do I need to renew business name registration in Kenya?+
Business name registrations under the new BRS system don't require periodic renewal of the name itself. However, you must keep your details updated with the Registrar (changes in address, partners, etc.) and renew your county Single Business Permit annually.
Can two businesses have the same name in Kenya?+
No. The eCitizen system prevents identical or confusingly similar names. The Registrar checks proposed names against the existing register. Names that sound the same, are spelled similarly, or imply association with another registered business will be rejected.
How long does it take to register a business name in Kenya?+
Name search results come within 24 hours. Once approved, the full registration process takes 3–5 business days. Total time from start to certificate: typically 4–6 business days, faster than limited company registration which takes 5–10 days.
What names are not allowed for business registration in Kenya?+
Names with restricted words like "Bank", "Sacco", "Insurance", "Trust", "Government", "Ministry", "National", "Royal", "Federal" require special approval and are typically rejected for ordinary applicants. Names too similar to existing trademarks or registered businesses are also rejected.
