Electrical installation is one of the essential stages of building a house.
It covers much more than sockets and light switches. A complete residential installation can include:
- wiring
- conduits
- sockets
- switches
- lighting points
- distribution boards
- circuit breakers
- earthing
- testing
- connection preparation
The final cost depends heavily on the size of the house, the number of electrical points, the quality of fittings, and the complexity of the system.
For the total project budget, see our guide to construction cost per square metre in Kenya.
How much does electrical installation cost in Kenya?
There is no single reliable national price for wiring a house.
Electrical contractors typically price installations according to factors such as:
- floor area
- number of rooms
- number of lighting points
- number of sockets
- cable sizes
- distribution-board requirements
- lighting specification
- backup-power provisions
- labour
- testing and certification
Kenyan electrical contractors commonly note that installation costs vary by project size and complexity rather than offering one universal house-wiring rate. Moffam Electricals
That means a compact bungalow with basic lighting and sockets will cost substantially less than a large maisonette with extensive lighting, outdoor circuits, electric showers, CCTV, networking and backup-power systems.
What does electrical installation include?
A typical residential electrical installation may include:
Wiring and conduits
Electrical cables are routed through conduits within walls, ceilings and floors.
The amount of cable required increases with:
- house size
- number of circuits
- socket locations
- lighting points
Distribution board
The distribution board controls and protects the circuits within the house.
It contains devices such as circuit breakers and other protective equipment.
Sockets and switches
A house with many sockets and switches will naturally cost more to wire.
This is particularly relevant in:
- kitchens
- home offices
- entertainment areas
- bedrooms
Lighting
Lighting cost can vary enormously.
A simple pendant light has a very different cost from:
- recessed downlights
- decorative fittings
- outdoor lighting
- feature lighting
- concealed LED systems
Earthing and protection
A safe electrical installation also requires appropriate earthing and circuit protection.
These are not sensible areas to economize through inferior workmanship.
Why do electrical costs vary so much?
1. House size
A larger house typically requires:
- more cable
- more conduits
- more sockets
- more switches
- more lighting points
- larger distribution systems
A 100 m² bungalow will therefore normally cost less to wire than a 250 m² maisonette.
2. Number of electrical points
Two houses of the same size can have very different electrical budgets.
One homeowner may request:
- one ceiling light per room
- basic sockets
- a simple kitchen layout
Another may request:
- multiple downlights
- bedside sockets
- USB outlets
- exterior lighting
- additional kitchen circuits
- CCTV
- data cabling
The second installation is substantially more complex.
3. Fittings and accessories
Switches and sockets vary greatly in price and quality.
Premium finishes, smart switches and designer fittings can materially increase the cost.
The same applies to lighting fixtures.
4. High-load appliances
Some appliances need dedicated circuits.
Examples can include:
- electric cookers
- ovens
- water heaters
- electric showers
- pumps
- air conditioning
The system needs to be designed around the electrical load of the house.
5. Backup power and solar
Many homeowners now also consider:
- inverters
- batteries
- generators
- solar systems
- automatic transfer systems
These should be treated as additional systems rather than assumed to be part of a standard wiring quote.
Who should carry out electrical installation in Kenya?
Electrical work should be handled by appropriately qualified and licensed professionals.
EPRA licenses electricians and registers electrical contractors. Verify the professional’s current licence and that it covers the work you need.
A completed installation may require tests covering matters such as:
- earth resistance
- insulation resistance
- continuity
- polarity
- earth-loop impedance
Ask your electrician to explain the inspection, testing and documentation required for your installation and connection. Include those responsibilities in the quotation.
What should an electrician’s quotation include?
Before comparing quotations, make sure you understand whether the price includes:
- cable
- conduit
- sockets
- switches
- distribution board
- breakers
- light fittings
- labour
- earthing
- testing
- certification
- external lighting
Otherwise, two quotations that appear very different may simply cover different scopes.
This same principle applies to contractor quotes generally. See What Should Be Included in a Building Contractor Quote?
First fix vs second fix
Electrical installation commonly happens in stages.
First fix
This usually happens before plastering and finishing.
It can include:
- conduits
- cable routes
- back boxes
- provision for circuits
Second fix
This usually happens later and may include:
- sockets
- switches
- fittings
- light fixtures
- final connections
Planning the electrical layout early helps avoid cutting into completed walls later.
How can you control electrical costs?
Plan socket locations before construction
Changing the layout after plastering or finishing can create unnecessary rework.
Decide your lighting strategy early
Do not wait until the end of construction to discover that you want dozens of additional downlights.
Separate essentials from upgrades
You might distinguish between:
Essential
- wiring
- sockets
- standard lighting
- distribution board
- safety systems
and:
Optional upgrades
- smart switches
- decorative fittings
- CCTV
- networking
- backup systems
That makes the budget easier to control.
Avoid unsafe shortcuts
Electrical work is not an appropriate place to prioritize the absolute lowest quote.
Poor workmanship can create:
- fire risk
- electric shock risk
- damaged equipment
- expensive repairs
Electrical work and house finishing
Electrical installation overlaps closely with the finishing stage.
Lighting fixtures, switches and visible accessories often form part of the final appearance of the house.
See our guide to house finishing costs in Kenya for the wider finishing budget.

Frequently asked questions
How much does it cost to wire a house in Kenya?
There is no universal figure. The cost depends on house size, number of electrical points, materials, fittings, labour and the complexity of the system. Kenyan contractors generally quote according to the project rather than a single national rate. Moffam Electricals
Is electrical installation priced per point?
Some contractors may use point-based pricing for parts of their quotation, but that should not be confused with a universal market rate. The total installation also includes cable, distribution equipment, earthing, testing and other work.
Should I use a licensed electrician?
Yes. Use an appropriately licensed electrician and confirm the testing and connection documentation for your project. See EPRA’s licensing guidance.
Does electrical installation include light fittings?
Not necessarily.
Some quotations may cover only the wiring and electrical points, while decorative light fittings are supplied separately. Always confirm the scope.
Final takeaway
Electrical installation costs in Kenya vary too much for one generic house-wiring price to be genuinely useful.
The biggest drivers are:
- size of the house
- number of electrical points
- quality of fittings
- lighting design
- appliance loads
- backup-power requirements
Plan the system early, compare quotations on the same scope, and use a qualified professional rather than choosing purely on price.
