How to Write a Quote for Trade Work

Why a proper quote protects you as much as the customer

Knowing how to write a quote for trade work is really about writing down, clearly and in advance, exactly what you will and won't do, and exactly what it will cost. A vague verbal quote ("should be about eight hundred, give or take") is where scope disputes and unpaid extra work both come from. A written, itemised quote protects the customer from surprise costs and protects you when the job turns out to involve more than expected.

It doesn't need to be complicated. A solid trade quote is a short, structured document: who it's for, what's being done, what it costs broken into sensible line items, what's excluded, and how long the price is valid for.

What every trade quote should include

1. Your business details and the customer's. Name, contact info, and the job address if different from the billing address.
2. A clear job description. Specific enough that there's no ambiguity about scope — "rewire kitchen circuit and install 6 new outlets," not just "electrical work."
3. Itemised pricing. Materials and labour broken out, or at minimum grouped by task, so the customer can see where the cost comes from.
4. What's excluded. Anything that would trigger extra cost if discovered mid-job — e.g. "excludes any rewiring found to be non-compliant with current regulations."
5. Deposit and payment terms. Whether a deposit is required, and when the balance is due.
6. Validity period. Material costs move — a quote valid for 14 or 30 days protects you from honouring an old price on materials that have since gone up.

Quote vs. estimate vs. invoice

These three terms get used loosely, but they mean different things and it's worth being precise with customers about which one you're giving them.

• Estimate. A rough, non-binding figure given before you've fully assessed the job — useful for an early conversation, but not something you should be held to exactly.
• Quote. A fixed, binding price for defined work. Once a customer accepts a quote, you're committing to that price for that scope.
• Invoice. The bill issued after the work is done (or at agreed milestones), based on the accepted quote.

Giving a customer a rough number over the phone and calling it a "quote" is a common source of disputes later. If you haven't seen the site or confirmed scope, say "estimate" — and follow up with a proper written quote once you have.

Worked example: a kitchen rewire quote

Here's an example of how a real line-item quote might look for an electrician rewiring a kitchen and adding outlets. Treat every number as an example — your own rates and material costs will differ.

Following up after a quote is sent

Sending a quote isn't the end of the process — a well-timed follow-up often makes the difference between a quote that gets accepted and one that quietly goes cold. A short check-in a few days after sending (by phone, text or email, whatever the customer used to first contact you) gives them an easy opening to ask questions or raise concerns about scope or price, rather than silently deciding to go with someone else. It also signals that you're organised and responsive, which matters to customers comparing multiple tradespeople on more than just price.

If a customer goes quiet, it's worth asking directly whether the price was the issue, the timeline, or something in the scope — the answer tells you something useful either way. Sometimes the honest answer is that your price simply wasn't competitive for that job, and that's fine; not every quote should convert, and trying to win every single one by cutting your price is usually a sign your baseline pricing needs revisiting rather than a reason to discount this one job.

When to revise a quote mid-job

Even a carefully scoped quote can run into something unexpected once work starts — old wiring that doesn't meet current code, rot behind a wall, a foundation issue under a floor. When that happens, the quote you already gave doesn't need to be honoured for work that wasn't in its scope, but how you communicate the change matters as much as the change itself.

1. Stop and document before continuing. A photo of the unexpected issue removes any ambiguity later about what was actually found.
2. Explain the finding and the cost impact clearly. Plain language, not just a new number — customers accept scope changes much better when they understand why.
3. Get sign-off in writing before proceeding with the extra work, even if it's just a quick text reply confirming the new cost.
4. Issue a revised written quote or a clearly labelled variation rather than folding the extra cost silently into the final invoice.

This is exactly why the exclusions section of your original quote matters so much — a clear exclusion list is what gives you the standing to say "this wasn't part of the original scope" without it feeling like a dispute.

Common quoting mistakes that cost tradespeople money

• Quoting from memory instead of from a site visit. Unseen access issues, old wiring, or non-standard fittings are exactly the kind of thing that blows up a phone-quoted price.
• No exclusions listed. Without a written exclusion list, "that wasn't included" arguments default in the customer's favour.
• No expiry date. An unquoted-for material price spike between quoting and starting the job comes straight out of your margin if the quote never expires.
• Underquoting to win the job. A quote that doesn't reflect real cost and time isn't competitive — it's a loss with extra steps.
• No deposit on larger jobs. A deposit isn't just cash flow — it also filters out customers who aren't serious before you've committed materials or schedule time.
• Reusing an old quote template without checking the numbers. Copying last year's line items and swapping the customer name is fast, but it silently carries forward material and labour costs that may no longer be accurate.

Most of these mistakes share a root cause: treating the quote as a formality to get through quickly rather than as the document that actually protects your margin on the job. A few extra minutes spent itemising properly, listing exclusions, and setting a realistic expiry date almost always pays for itself the first time a job doesn't go exactly to plan.

Once your quote template is solid, the harder question is often how to price the job itself — hourly vs fixed price, and what overhead to build in as a solo operator. Our guide on pricing jobs as a solo tradesman covers exactly that, with its own worked example.
