If you want to embark on an electrical wiring project or upgrade an electrical system to the modern design, it is crucial you have a rough idea of the project’s cost before you proceed with it. Although, The cost of electrical wiring depends on many factors; considering them to get a rough budget for the project could be of great help to you. So, Below are some of the various factors you must look into;
Size of the House
The size of the building is one of the major factors to consider when embarking on an electrical wiring project because other factors depends on it, such as:
The duration of time it will take to complete the job
The materials that will be needed for the job
The numbers of fixtures — such as outlets and lights — to install
And if you have any attached structures, such as storage sheds or garages, that will be wired, then it needs to be considered also in the overall size of the house.
Configuration of the House
The layout or configuration of the house also contributes to the challenge of the work and hence the total cost of an electrical wiring project. The configuration refers to;
The total numbers of rooms and how they are dimension
The ceiling height of each room
The number of stories
The total number of special rooms.
The total numbers of bathroom
The number of stores and kitchen etc
For example, when wiring the bathrooms it has to use water-resistant materials and ground fault circuit interrupter (GFCI) outlets, which are more costly than standard materials. And that is not the same materials for wiring a storage room or bedroom, which implies that having many bathrooms in the building may increase the cost more than an additional storage room.
Quality of Material
Just like other construction materials electrical material also differs in quality, and high-quality materials are relatively expensive. For example;
copper and brass wiring is usually of high quality than aluminum wiring
Some low-quality outlets accessories and fittings have thin electrical contacts that don’t last for long compare to high-quality outlets accessories and fittings.
Also Some low-quality accessories and fittings outlets have fewer hole configurations than their high-quality counterparts
So careful consideration is to be given into this factor because the lifespan of the electrical wiring installation is determined by this factor and also if the wrong choice is made here you might even lose your entire building due to fire outbreak which might result from inferior electrical material.
Scope of the Work
Electrical wiring includes different jobs; the nature and number of jobs you need the contractor to provide determines the cost of the job. For example, a wiring project may encompass;
Pipping of the building to create cable rout in walls, floors, and ceiling. Also, fixing accessories for each outlet either power or lighting point.
Running of cable from the consumer unit panel to different parts of the outlets in the house
Installation of light accessories/ fittings
Installation of electrical power accessories such as cooker unit, 13amps socket 15amps socket etc.
Installation of electrical fitting such as ceiling fans, water heater, washing machine, etc.
The more of these things you need the electrician to do the higher the wiring cost will go.
Electrical Permits and Inspections
A sizable electrical wiring project is likely to require many permits from the relevant authorities. Some permits may include:
A permit to install a low-voltage system in the building such as a security system(not be applicable in all countries)
A permit to install additional circuit if the previous ones were not enough for your usage (not applicable in all countries)
A permit to upgrade the circuit box in the house ( not applicable in all countries)
In addition to acquiring the permits, you may also require inspections once the wiring is complete by the government authority in charge of that, The inspection will be done to certify that the work is up to the standards the government requires. Although Permits cost money, the more permits you require, the higher the overall cost you will get.
Electrical Code Issues
If the upgrade is to be done in the electrical wiring of your house or replace your current wiring, then you may have to update your electrical wiring design and codes to match the current ones. In some countries, the Electrical codes change all the time, and each time you upgrade your electrical wiring, the government requires you to keep your electrical codes up to date to match the current ones.
For example, if you had normal power outlets in the bathroom, it is crucial you should upgrade to outlets with GFCI protection when you upgrade your bathroom wiring. And if this is not done, Your house will not pass the electrical inspection test, if you don’t upgrade the wiring to the new codes.
