How to Estimate Electrical Work: Step-by-Step Guide for Electrical Contractors

Table of Contents

As an electrical contractor, you must correctly estimate the costs that you will incur in a project and make a bid to win the contract. However, for most contractors in the industry, preparing estimates can be quite challenging.

That’s why you should follow the right approach and use modern tools to make the process smooth and easy. When making an estimate, you have to figure out the materials, labour, and other costs that you need to incur to complete a project.

In this guide, we’ll break down the step-by-step process so that you can easily make estimates for your electrical work. We’ll also show you how the best software for electrical contractors and other tools can help streamline the entire workflow.

Initial project assessment

How to Estimate Electrical Work: Step-by-Step Guide for Electrical Contractors

Before starting a project, there are a couple of things that you must do to assess the job. Let’s break them down into three areas and look at them individually.

Reviewing project scope

Before you even think about starting an electrical project, it’s important to get a handle on the full scope of work. Therefore, you should go over the project requirements, blueprints, and timelines to figure out exactly what the client expects.

As an electrical contractor, you should figure out what kind of wiring, panels, or other fixtures you need for the job. Are there any complex installations like custom lighting or security systems? How long will it take for you to complete the job? All these details matter because they help you to build an accurate estimate that can cover the costs that come up down the line.

Site inspection

A site visit is where the real understanding happens. Seeing the project space in person helps you assess challenges like tricky wiring paths, outdated electrical systems, or access issues. You might even find things like tight spaces or older structures that could affect your approach and, ultimately, the estimate.

Is the space already wired, or will you need to start from scratch? Are there areas that might require extra safety measures? Inspecting the site in person helps you to figure out what materials you’ll need and how much labour will be required.

Gathering client requirements

Every client has their vision and requirements, so it’s important to sit down with them and get a clear idea of their expectations. Do they want energy-efficient solutions? Maybe they’re looking to add smart home systems or need specific outdoor lighting for their backyard.

It’s important to get these details at the beginning to customise your estimate to fit their preferences and budget. Further, discussing these facts upfront will help to avoid misunderstandings down the road and ensure both parties are on the same page about what’s expected.

Make sure to take some time to look at your competitors and find out what they are offering and, more importantly, what they aren't offering.

Calculating material costs

As you know, you need various types of materials to complete an electrical project. You should account for all these materials correctly when making your estimates. Let’s look at how you can do this easily step-by-step.

List of required materials

When it comes to calculating material costs, the first step is to make a detailed list of everything you’ll need for the project. Make sure to include all the essentials like wiring, switches, outlets, panels, circuit breakers, and even smaller items like connectors or fasteners. Take your time to figure out the precise quantities of materials that you would need to complete the job.

As you already know, the type and quality of the materials you choose can also have a big impact on your costs. So, it’s important to have a clear idea about the requirements of the project to allocate a cost for the materials.

Sourcing material costs

Once you know what kind of materials you need, the next step is to figure out how much they cost. There are a couple of methods that you can use to check the prices.

On top of the head, you can look up the prices online, check with local suppliers, or even use historical data from past projects to get an idea. It’s always better to build strong relationships with suppliers because it can help you get better deals or discounts, especially for bulk purchases. You have to always keep in mind that the material costs can fluctuate. So, it is better to stay updated about the current prices to avoid any surprises.

Accounting for waste

Let’s face it, no project will ever go perfectly according to the plan. This is why you should account for some waste and unexpected expenses. Leave a buffer in your estimate to account for extra wiring or even a couple of damaged materials.

A general rule of thumb is to add around 10% to your material costs to cover wastage or unexpected issues. Planning for this upfront can save you headaches down the road and help you stick to the project’s budget.

Estimating labour costs

Now that you have calculated the material costs, you should correctly estimate the labour costs. There are three simple steps that you can follow to calculate the cost. Let’s look at them one by one.

Labour hours calculation

When estimating labour costs, you should figure out how many hours each task will take. As electrical contractors, you have to break down the project into tasks like wiring, installing panels, or setting up lighting, and estimate how long each will take based on your team’s experience.

When you have a detailed breakdown of labour hours, you can make the estimate more accurate and ensure that your overall costs are accurate and realistic.

Make sure to factor in things like set-up and cleanup time, which often get overlooked but can increase your labour hours. Further, don’t forget that you may need extra time to complete larger and more complex projects.

Labour rates

Once you’ve nailed down the number of hours, the next step is to apply the relevant labour rates. These rates will vary depending on the skill level and experience of your team members.

For instance, electricians with more experience or specialised skills will command higher rates than junior team members or apprentices. Make sure you’re using accurate rates that reflect local industry standards, so you’re not underestimating costs. It’s also helpful to have an updated rate card for your team to make this process smoother.

Overtime and specialised labour

As you already know, some projects need a bit more than the standard work time. So, if your project has tight deadlines, you should factor in overtime charges, which will affect your labour costs.

Additionally, you may need to bring in outside contractors with the right expertise. For example, you might need specialised labour to handle high-voltage installations or custom smart home set-ups. These specialised skills often come with premium rates, so it’s essential to include them in your overall labour estimate.

Adding overhead and profit margins

The next step on our list is to add overhead costs and profit margins. Let’s take a look at how you can do this easily without stressing out.

Overhead Costs

These are the fixed expenses like office rent, utilities, transportation, insurance, and the maintenance of your equipment that keep your business running. As you can see, these expenses are not directly tied to a specific job or contract, but you still must incur them to run your business.

That’s why you still have to consider them in every estimate to keep your business profitable. You must calculate these costs accurately and spread them out across your different projects, so you’re not leaving money on the table.

Profit margin calculation

Once you’ve accounted for overhead, it’s time to set your profit margin. This is where you determine how much profit you want to make on top of the project’s costs.

Your profit margin will depend on your business goals, industry standards, and what the competition is charging. Typically, contractors aim for a margin between 10-20%, but this can vary depending on the project’s complexity and market conditions. 

Setting the right profit margin will help your business grow and stay competitive in the market without undervaluing your work.

Reviewing and finalising the estimate

This is the final step of preparing a solid estimate. At this stage, you should make sure that your figures are accurate. Let’s look at how you can do this easily.

Cross-checking for accuracy

This step helps ensure you haven’t missed anything, that could throw off your entire budget. As an electrical contractor, you must make sure everything from material costs to labour hours and overhead has been accurately calculated.

It’s also helpful to get a second opinion or use estimation software to verify your calculations. By cross-checking for accuracy, you can avoid costly mistakes and provide a more reliable estimate to your clients.

Presenting the estimate to clients

Once everything is reviewed and polished, it’s time to present the estimate to your client. A clear, transparent, and well-organised estimate helps build trust and gives clients confidence that they’re getting good value for their money. 

Break down the costs, materials, labour, and overheads in a way that’s easy to understand. Offering an itemised estimate can also make clients feel more informed and reduce the chances of disputes later. 

Use the best software for electrical contractors

As you already know, electrical contractors need more efficient and accurate solutions to stay ahead of the competition in the modern, fast-paced world. That’s where estimation software comes in.

The right software solution can significantly improve the speed and accuracy of your estimates. It allows you to quickly adjust numbers if materials change or labour rates fluctuate, saving you time and hassle.

Plus, these tools help ensure that you don’t miss any critical details, so your estimates are always reliable. Software that handles time-consuming tasks like preparing estimates will free you up to focus on what matters: doing the jobs efficiently.

Key software features
