Electrical wiring in Nairobi: new installations, rewiring and fault-finding

Why choose this service
Safer buildings
Correct cable sizing, protective devices and earthing reduce the risk of overheating, shock and fire.
Fewer faults
Neat terminations and tested circuits prevent the nuisance tripping and dead sockets that come from rushed work.
Easier maintenance
A labelled distribution board and clear circuit layout save time and money on every future job.
Ready for upgrades
We leave capacity for solar, generator changeover and added loads where you plan them.

What affects the price
- Number of lighting, socket and appliance points
- Concealed (in-wall) or surface conduit and trunking
- Cable size and type needed for each circuit
- Size and quality of the distribution board and protective devices
- Building size, number of floors and access
- Whether it is new work or a rewire in an occupied building
Wiring is usually quoted per project from a site visit, because points, cable runs and finishes vary widely. We provide an itemised quotation so you can see materials and labour separately.

Why does my breaker keep tripping?
The usual causes are an overloaded circuit, a faulty appliance, a short circuit, an earth leakage fault, damp or a loose connection. Do not replace the breaker with a larger one. Read <a href="/blog/why-does-my-breaker-keep-tripping/">Why does my breaker keep tripping?</a> or call us to diagnose it.
How do I know if my house needs rewiring?
Warning signs include frequent tripping, warm or discoloured sockets, burning smells, flickering lights, no earthing, brittle cable insulation and an old board with rewirable fuses. See <a href="/blog/signs-your-house-needs-rewiring/">Signs your house needs rewiring</a>.
Can you rewire an occupied house?
Yes. We plan the work in stages, so you can keep using parts of the property, and test each circuit as we go.
Do you wire buildings that are still under construction?
Yes. First-fix wiring is done before plastering and second-fix after finishing. We coordinate with your contractor to match the building schedule.
Do you install earthing and RCD protection?
Yes. Earthing, RCD protection and surge protection are part of a correct installation. Read <a href="/blog/earthing-and-rcd-protection-explained/">Earthing and RCD protection explained</a>.
Can you wire a house for solar or a generator?
Yes. We can separate essential circuits, install changeover switching and prepare the distribution board so solar or a generator can be added cleanly.
