About Nerpax Systems
One team, from site survey to handover
We supply, install and commission electrical, security and power systems for homes, businesses and institutions across Nairobi and the surrounding counties.
The problem with fragmented contractors
Most property owners in Kenya know the story. One fundi wires the house, another firm fits the CCTV, a third person installs the gate motor and someone else does the electric fence. When something fails, everyone blames everyone else, and you are left paying for the same fault twice.
Cameras stop recording because the power supply was undersized. A gate motor burns out because nobody fitted surge protection. Breakers trip because the wiring was never sized for the load. These are not bad luck. They are the result of nobody owning the whole system.
The same happens with materials. Fake cables, counterfeit breakers and low-grade cameras look fine on the day they are fitted, then fail months later. By then the contractor has moved on and the cost lands on you.
Nerpax Systems exists to fix that. We take responsibility for the complete job, so you have one team to call and one team accountable for the result.
Supply, install and commission: how we work
Every project follows the same three stages, whether it is a single CCTV camera or a full electrical and security fit-out.
- Supply: we specify and supply genuine equipment that suits your site and budget, not whatever is cheapest on the day. You can also buy materials directly from our online shop.
- Install: our team installs neatly and safely, following the Kenyan wiring regulations and safety standards. Cables are routed, labelled and protected properly.
- Commission: we test and configure everything, then walk you through how it works before handover. A system is not finished until it is proven to work.
It starts with a conversation. Send us a quote request or book a site visit and we will assess what you actually need.
Because the same team handles the CCTV, the wiring, the backup power and the gate, everything is planned to work together. Cameras get a protected power supply, gate motors get surge protection and battery backup, and the distribution board is laid out with room for what you add later. When you need support after handover, you call one number and speak to people who know your installation.
Who we serve and what we stand for
We work with homeowners, landlords, contractors, businesses, companies and institutions such as schools, churches and clinics. We also supply materials to resellers and contractors who need genuine stock and honest advice.
Whether you are securing a family home in Kiambu, fitting out rental units, upgrading a shop or office, or planning power backup for a school or clinic, the approach is the same: understand the site, recommend what fits the need and budget, and do the work properly the first time.
Our values are simple and they show in the work:
- Safety first: correct cable sizes, proper protection and earthing, and no shortcuts that put people or property at risk.
- Genuine equipment: no fake or low-grade products that fail within months.
- Neat work: tidy cable runs, clean terminations and a site left as we found it.
- Clear quotes: itemised pricing in KES, so you know exactly what you are paying for before work starts.
