Introduction — Powering your home and business the right way
Electricity keeps modern life and business running — but a poor installation or a DIY job can cost you time, money and safety. GossTech understands that every wiring plan, distribution board, solar tie-in and earthing system must be designed and installed to code, with efficiency and long-term reliability in mind.
Whether you’re building a new home in Karen, upgrading a shop in the CBD, fitting a factory on the outskirts of Nairobi, or installing solar + battery backup in Kisumu, GossTech brings certified electricians, proven processes and a safety-first mindset to every job. This pillar post explains who we serve, the full scope of our electrical services, how we work, and why clients across Nairobi and Kenya choose GossTech.

Detailed service descriptions — what we do in each area
Below we break down the major service areas and describe what GossTech delivers for each, including typical deliverables, technical approach and what clients can expect.
1. Residential electrical installations
What we do: Full house wiring for new builds, extensions, complete rewiring for older properties, distribution board upgrades, earthing & lightning protection, lighting design & installation (indoor/outdoor), power sockets, dedicated appliance circuits (cookers, electric water heaters), RCDs and safety devices.
How we work: We start with a site survey and load assessment, produce a wiring diagram and bill of materials, propose a quote, then proceed with staged installation and inspection. Final handover includes testing, labeling, and a compliance checklist.
Why it matters: Correctly sized cables, protective devices, and properly earthed systems prevent fire risk, nuisance tripping and expensive future repairs.
2. Commercial installations (shops, offices, restaurants)
What we do: Fit-out power and lighting, emergency lighting and signage, small sub-distribution boards, metering coordination, data/comms cabling coordination (with your IT partner), UPS backups, access control power supplies.
How we work: We coordinate with interior designers and MEP teams, submit layouts, and schedule installations to not disrupt trading hours. We also provide after-hours installation where required.
Typical deliverables: Single-line diagrams, labeled circuits, energy-efficient LED lighting retrofits, and workplace safety compliance certificates.
3. Industrial & factory electrical works
What we do: Design and install high-current distribution systems, motor control centers (MCC), variable speed drives (VSDs), three-phase power, heavy machinery hook-ups, industrial earthing systems and surge protection.
How we work: Industrial jobs begin with a detailed electrical load audit and risk assessment. We deliver electrical schematics, provide protective relay settings where necessary, and commission equipment with factory acceptance testing.
Safety & compliance: Thermal imaging, harmonic analysis and power factor correction services are available to optimize energy use and ensure reliability.
4. Solar PV & hybrid systems (grid-tied & off-grid)
What we do: Design, supply and install solar PV arrays, inverters, batteries and battery management systems, AC coupling for backup, metering integration and system monitoring.
How we work: We perform site solar assessments (shading, tilt, azimuth), size PV and storage to match load profiles, and provide a return-on-investment and payback estimate. Installations include DC string wiring, inverter installation, AC integration and earthing per standards.
Maintenance: Battery health checks, inverter firmware updates and cleaning plans.
5. EV charging installations
What we do: Install home and commercial EV chargers, dedicated circuits, load studies, and charging infrastructure for apartments and offices.
How we work: We evaluate supply capacity, recommend single-phase or three-phase chargers, and, if needed, upgrade distribution boards or arrange for metered sub-circuits.
Safety: RCD type A protection, correct cable sizing and segregation of circuits to prevent overloads.
6. External & street lighting
What we do: Design and install street lighting, pole-mounted luminaires, garden and security lighting, and programmable lighting controls for efficiency.
How we work: We handle civil coordination, pole foundations, cable trenches and supply remote monitoring for public or estate lighting projects.
7. Testing, inspection & certification
What we do: Full electrical testing: insulation resistance, continuity, earth loop impedance, RCD tests, thermal scans and PAT testing for portable appliances. We issue compliance reports and certificates where required.
Why it matters: Scheduled testing reduces unexpected downtime and ensures compliance with regulatory requirements.
8. Preventive maintenance & emergency response
What we do: Scheduled maintenance contracts — inspections, cleaning of DBs, tightening of connections, thermal imaging to catch hotspots early. Emergency 24/7 fault-finding for trips, outages and dangerous faults.
Response: We maintain skilled teams for rapid diagnostics and safe restoration.
