How to Start an ISP in Kenya: CAK Licence Types, Costs and Requirements (2026)

By the ECA Networks technical desk · Last updated 21 September 2026

Most first-time founders get the equipment budget roughly right and then get caught out by licensing timelines and working capital. Here is the full path, in order, from paperwork to your first paying customer.

Short answer

To start an ISP in Kenya you need a Communications Authority of Kenya (CAK) licence, either an ASP licence to sell internet access or an NFP licence if you are also building your own infrastructure, plus core network equipment and enough working capital to run for three to six months before you break even.

What licence do you actually need?

Kenya splits telecom licensing by what you do, not just that you sell internet.

  • ASP (Application Service Provider) licence covers the service of providing internet access to customers. This is the one almost every ISP or WISP needs, whether you own infrastructure or ride on someone else's.
  • NFP (Network Facilities Provider) licence covers building and operating network infrastructure such as towers, fibre and backhaul links. You need this if you are laying your own fibre or running your own wireless network, not just reselling capacity.

Most small ISPs end up holding both

An ASP licence to serve customers, and an NFP licence, usually Tier 3 and county level, to legally operate the physical network. If you only plan to resell a larger provider's capacity with no infrastructure of your own, the ASP licence alone may be enough to start. Confirm your specific case directly with CAK, since requirements are updated periodically.

NFP licence tiers: what coverage costs you

The NFP licence is tiered by geographic reach, and the tier you apply for should match where you actually plan to operate. Applying for national coverage before a single site is live is a common and costly first-year mistake.

Fees and specific documentation requirements change from year to year, so treat any figure you see quoted, including here, as a starting estimate. Always confirm current fees directly on the Communications Authority of Kenya's licensing page before budgeting.

Tier 3Single countyMost first-time WISPs, start here
Tier 2Regional, multiple countiesOnce you have proven demand beyond one county
Tier 1NationalEstablished operators scaling infrastructure nationally

What CAK will ask for

Across ASP and NFP applications, expect to prepare:

  • Certificate of incorporation and company KRA PIN
  • A technical and business plan describing your intended service area, technology and rollout timeline
  • Proof of technical capacity, such as staff qualifications or a technical partner
  • Application and licence fees for your chosen tier
  • Compliance undertakings covering data protection, consumer protection and numbering where applicable

Equipment you need before your first customer

Licensing runs in parallel with equipment planning. Do not wait for the licence to land before speccing your network, or you will lose months.

  • Backhaul: fibre, a microwave or wireless link, or Starlink to reach your upstream provider
  • Core network gear: an OLT if you are building FTTH, or a MikroTik-class router and distribution switch if you are wireless-first
  • Client-side CPEs: ONTs for fibre customers or CPE radios for wireless customers, stocked for your first 20 to 50 signups rather than your five-year target
  • Backup power: grid power in Kenya is not guaranteed uptime, so budget for UPS or solar backup at every active site from day one

Budgeting realistically

Most new ISPs underestimate one line item specifically: working capital. Licensing and equipment are costs you can plan for precisely. What catches founders out is the three to six months between the network going live and revenue covering costs, during which staff, site rent, bandwidth commitments and support all run regardless of whether you have hit your customer target. Budget for this explicitly, separate from equipment spend.

A realistic launch timeline

  1. 1Weeks 1 to 4: file ASP or NFP applications, finalise the technical plan, start equipment sourcing in parallel
  2. 2Weeks 4 to 10: site preparation, backhaul agreement, core equipment installed and tested
  3. 3Weeks 8 to 12: licence approval (timelines vary, confirm current CAK processing times), first pilot customers connected
  4. 4Month 3 onward: scale customer acquisition against the equipment and capacity you have already proven works

Frequently asked questions

Do I need an NFP licence if I'm just reselling another provider's internet?+

Not necessarily. If you have no infrastructure of your own and are purely reselling capacity, an ASP licence may cover you. Confirm your specific model with CAK, since the line between reselling and operating facilities depends on exactly what equipment you own and control.

How much does it cost to start an ISP in Kenya?+

It depends heavily on scale and whether you are wireless-first or fibre-first, with licensing, equipment and three to six months of working capital as the three main buckets.

Can I start with a wireless network and add fibre later?+

Yes. Many Kenyan WISPs start wireless because it is faster and cheaper to deploy, then extend fibre to high-density areas once the customer base justifies the investment.

How long does CAK take to approve a licence application?+

Processing times vary by licence type and are set by CAK, not fixed industry wide. Check current timelines on the Communications Authority's licensing page before building a launch date around an assumption.
