Earthing & Lightning Protection
Proper earthing and lightning protection are non-negotiable safety infrastructure, particularly for buildings with sensitive equipment or exposed locations. We design, install, and test earthing systems and lightning protection to measured, documented standards.
Scope of work
- Earth electrode design and installation
- Earth loop impedance testing
- Lightning protection system design and installation
- Surge protection device installation
- Compliance testing and certification
Technical considerations
- Earth electrode design matched to the measured soil resistivity
- Lightning protection assessed for the building’s height and exposure
- Surge protection coordinated with earthing so it has somewhere real to discharge to
How this work comes together
Earth electrode design
Earthing arrangement designed and installed to suit the site’s actual soil conditions.
Lightning protection installation
Air terminals, down conductors, and earth termination installed to the building’s exposure level.
Surge protection
Surge protection devices fitted and coordinated with the earthing system.
Testing & certification
Earth loop impedance tested and results documented for compliance records.
Properties that typically need earthing & lightning protection
How we scope, install, and hand over the work
Assess
Site survey, load assessment, and diagnostics. We measure the actual conditions before proposing a scope.
Design
A written design based on the assessed load: circuit schedules and single-line diagrams you keep.
Install
Work executed by our certified team to the documented design, with safety isolation and site protocols observed throughout.
Test & Handover
Commissioning tests, compliance checks, and as-built documentation handed over. Not just a completed job, a documented one.
You get the paperwork, too
Depending on scope: installation records, circuit or equipment schedules, testing results, and as-built information where produced. See what we hand over on every project.
Common questions
What services does Kell Electricals provide?
A full range of electrical engineering services: wiring and installation, panel repair and upgrades, solar and hybrid inverter systems, home automation, CCTV and security, generator installation and maintenance, industrial electrical systems, and scheduled preventive maintenance. The full list is on our Services page.
Do you offer ongoing maintenance, or only one-off jobs?
Both. We handle one-off installation and repair work, and also offer scheduled preventive maintenance contracts (panel inspection, thermal imaging, generator and solar system checks) for clients who want faults caught before they become outages.
Do you work on both residential and commercial projects?
Yes, and industrial too. Scope, documentation, and compliance requirements differ by property type, which is why we treat residential, commercial, and industrial work as distinct engineering problems rather than the same job at different sizes.
Can you work alongside my architect or contractor on a fit-out?
Yes. Commercial and office fit-out electrical work is a regular part of our scope, coordinated with architects, M&E consultants and the wider construction timeline.
Do you have examples of completed commercial electrical work?
Yes. For example, we delivered the complete electrical decking, conduit piping, wiring, and fixture installation and finishing for a cooperative society's building in Garki II, Abuja. See our Projects page for more recent work across residential, commercial, and industrial properties.
How much does house rewiring cost in Abuja?
It depends on the property's size, current wiring condition, and how many circuits, sockets, and fixtures are involved. Rewiring a two-bedroom flat and a multi-storey house aren't comparable jobs. We don't quote a number without a site visit, since guessing risks under- or over-pricing the actual scope. Request a quote and we'll assess the property directly.
What do hybrid inverter systems cost in Nigeria?
Hybrid inverter and battery system pricing depends on inverter capacity, battery chemistry and bank size, and whether it's a backup-only setup or one designed to carry most of your daily load (see our guide on sizing a hybrid inverter system for why that distinction matters). We size and quote from a real load assessment.
How much does smart home automation cost?
It scales with scope. A few automated lighting circuits costs far less than whole-property lighting, climate, and access control on one platform. Retrofitting an existing property also typically costs more than wiring automation into a new build from the start. We scope and quote after understanding what you actually want to control.
Read full review on Trustpilot →Kell Electricals did an outstanding job at my Gwarinpa home! They professionally installed my inverter and solar panels, set up my CCTV system, and replaced my home's switches, all of which are working perfectly. Their team was incredibly professional, and their work was remarkably clean and precise. For top-notch electrical services, I highly recommend Kell Electricals!
