Electrical quotation: what to include so the customer signs

In short

Build every electrical quotation in the same order: scope, materials, labor, exclusions, validity, then payment terms. Use that layout each time so customers can compare you line by line and variations attach to a specific line.

An electrical quotation needs seven things, in this order: your details and the customer's, a scope of work, a materials schedule, labor, exclusions, validity, and payment terms. Put them in that fixed sequence every time and the customer can compare your price line by line against others. You can also price a variation later by pointing at the exact line it changes. This guide sets out what goes in each section, what to write, and the mistakes that cost electrical contractors margin.

Why the order matters

Most customers do not read an electrical quote the way you wrote it. A facilities manager or homeowner often holds two or three quotes side by side and looks for the differences. If yours puts the total first, buries exclusions in small print and mixes labor into the materials, they cannot compare it. They pick the one they understand, which is not always the cheapest.

A fixed order also helps you. When scope comes before price, the price is tied to something specific. When exclusions sit right after labor, nobody can say they did not see them. And when every job follows the same layout, a variation is simply an edit to one section rather than a new argument about the whole job.

1. Header: who, for whom, and which job

Start with your business name, address, contact details and any registration your market expects. In the UK that means your NICEIC, NAPIT or similar scheme number. Add a unique quote number and the date, then the customer's name and the site address. Sequential numbering such as EQ-2026-047 lets you find the quote again when the customer rings six weeks later.

Put the drawing or specification revision here too if you are pricing from plans. A quote based on "Drawing Set E-1 to E-6, Revision 2" gives you a fixed baseline. If the architect issues Revision 3, you have a clean reason to reprice.

2. Scope of work: what you will deliver

The scope is the section where most quotes fall short. One sentence such as "rewire the property" is not a scope. Describe the work in the terms the customer will check it against. Say what the customer will have when you finish, not just what you will do.

For a domestic rewire, that means a circuit schedule: how many socket circuits, how many lighting circuits, which appliances have dedicated circuits, the consumer unit type and the number of sockets, switches and light positions. For a commercial fit-out, list the new distribution board, the number of circuits, the fixture schedule and the final connections to other trades' equipment.

State the testing and certification you will provide. In the UK, notifiable domestic work ends with a BS 7671 certificate and, where required, a Building Regulations compliance certificate. Other countries have their own inspection and sign-off rules, so name the one that applies to the job. A quote that never mentions certification leaves the customer to guess whether it is included.

3. Materials: itemized and priced separately

List materials as their own block, apart from labor. Show the consumer unit or distribution board, cable by type and run, accessories, fittings and containment. Where the customer chooses the finish or the fittings, say whether you are supplying them or allowing a provisional sum.

Separate materials matter for two reasons. Commercial customers often need to get budget approval, and a visible breakdown makes that easier. And when the scope grows, you are adjusting specific lines rather than revising a lump sum with no history.

If you sell or specify lighting, say so line by line. Fixtures, drivers, controls and emergency units are often the largest material cost and the most likely to change. Contractors working on lighting and electrical projects can see how this looks in practice on the lighting and electrical industry page. If you offer a choice of specification, a good, better, best layout works well. Tiered quotes let you present the options in one document so the customer picks a tier rather than asking for three separate quotes.

4. Labor: hours, rates and phases

Show labor as a separate section, broken into phases where the job has them: first fix, second fix, testing and commissioning. State whether you are pricing a fixed sum per phase or hours at a stated rate. Fixed sums per phase are easier for the customer to compare. Hourly rates are easier for you to adjust when something changes.

Whichever you choose, write it down. Underpriced labor is the most common way electrical jobs lose margin, because the hours that vanish are the ones nobody listed: travel, waiting for other trades, access difficulties and testing. Include allowances for them or state the conditions that would trigger extra time.

Access is the biggest variable. Rewiring a house with lifted floors and open walls takes far less time than rewiring a finished property where every cable run means lifting carpets and chasing plaster. Say which you assumed.

5. Exclusions: what you are not doing

A scope tells the customer what you will do. Exclusions tell them what you will not. This short section prevents more disputes than any other. Give it its own heading and write each exclusion as a plain line.

Common electrical exclusions include:

• Making good plasterwork, patching and painting after first fix.
• Low voltage, data or structured cabling, unless listed in the scope.
• Utility or network operator fees, meter work and service connection charges.
• Work outside the stated drawings or specification revision.
• Demolition beyond what the electrical work needs.
• Hazardous material removal, such as asbestos found behind walls.
• Supply of fittings and appliances the customer is providing.

Anything electrical and not mentioned is an argument waiting to happen. Either include it in the scope or exclude it here. In the UK, who pays for the network operator to disconnect and reconnect the supply is a frequent gap, so name the party responsible.

6. Validity: how long the price holds

State a validity period and give a reason for it. Many UK templates use 30 days. Some sources suggest as little as 15 days for jobs with heavy cable content, because copper-driven cable prices can move and a quote accepted two months late at old rates can erase the margin. Pick a period that matches how fast your supplier prices change, and add a line saying that material prices are reviewed if the quote is accepted after that date.

Put the expiry date on the quote itself, not just a phrase like "valid for 30 days". An actual date removes any doubt and prompts the customer to decide.

7. Payment terms: when the money arrives

Close with how and when you are paid. For small domestic jobs, a deposit on acceptance and the balance on completion is usual. On larger work, tie payments to milestones such as first fix, second fix and certification. Commercial jobs may also carry retention, so state the percentage and the release condition.

One published template for larger jobs suggests a deposit of 10 to 30 percent, milestone payments, and retention of 5 to 10 percent on contractor work. Treat figures like these as starting points and use your own policy. The point is that the schedule is written before work starts. Specialty contractors in the US are reported to wait more than three months on average to be paid, and a written schedule is the clearest protection against that.

Add your terms for variations here too: any change to scope must be agreed in writing, and priced using the rates and lines already on the quote. That sentence is what makes later variations quick to price, because the labor rates and materials lines they refer to are already agreed.

Pricing variations from the same structure

Because every section is separate, a variation is easy to write. A customer asks for six extra sockets. You do not rewrite the quote. You add a variation that cites the circuit schedule, adds the materials lines, adds the labor hours at the agreed rate, and states the effect on the programme and total. The customer sees the same layout they already accepted.

Use an approval step for anything that changes price. With approvals, a discount or a margin below your floor can be held for a manager's sign-off before the quote leaves the building, so the numbers you send are numbers you can stand behind.

Making the structure repeatable

A fixed order only works if you actually follow it every time. Build the layout once as a standard document, then reuse it. Document templates let you lock the section order, wording for exclusions and payment terms, and branding. Your estimators then fill in the job-specific content rather than starting from a blank page or an old quote with the wrong customer name in it.

If you quote regularly, quote software keeps materials, labor and totals in one place, so the arithmetic is right and a revision does not overwrite the version the customer accepted. Whatever tool you use, check each quote against the seven sections before it goes out.

Final check before you send

Read the quote as the customer would. Can they find the scope in under a minute? Do materials and labor add up to the total shown? Is every exclusion visible? Is the expiry date on the page? Are payment terms stated? If any answer is no, fix it first. A clear quote is faster to approve, easier to defend and simpler to change.
