A decorator sends a WhatsApp message: "Paint hallway, stairs, landing — £620." Three words, one number. The homeowner has two other quotes. Both arrived the same week. Both are one-page PDFs with the scope written out clearly, a breakdown of prep and coats, what's excluded, a start date, and a 14-day validity. The WhatsApp message sits at the bottom of the list.
The price is fine. It's competitive. But the message doesn't feel like a proper business. So the job goes to someone else.
Most tradespeople lose quotes before anyone even looks at the number. It's not the price that's the problem. It's everything around it.
Quote or Estimate — The Difference Actually Matters
Most tradespeople use the words interchangeably. Their customers don't. And legally, they're not the same thing.
A quote is a fixed price. Once a customer accepts it, it's a binding agreement. If the job takes longer than you expected, that's your problem to absorb — unless extra work comes up that you've agreed in writing beforehand. A quote is a commitment.
An estimate is a rough figure. It can change. Both parties are supposed to know that going in.
The problem is that most tradespeople send "estimates" but their customers read them as quotes. That gap is where disputes start. A customer who was expecting a fixed price and then gets hit with a bigger final invoice has a genuine grievance, even if you called it an estimate.
A written quote, once accepted, is a binding agreement. Citizens Advice is clear on this. So is the law. That's not a reason to avoid written quotes — it's a reason to write them properly, with the right scope, the right exclusions, and the right terms.
Use the word quote when you mean a fixed price. Use estimate only when you genuinely need wiggle room, and say upfront why the number might move. Don't use both words in the same document. Pick one and mean it.
What a Winning Quote Actually Contains
A one-line price invites comparison on nothing but the number. A quote that gives the customer something more to go on shifts the decision away from pure price. Here's what that looks like in practice:
- Who you are.Name, business name, phone number, email. Obvious, but it's missing from a lot of quotes. If there's a dispute, the customer needs to know who they're dealing with.
- The date and a validity period."This quote is valid for 30 days." Material costs move. Your diary fills. A quote sent in February and accepted in June can put you in a difficult position if you haven't put a time limit on it.
- The full scope of work.Exactly what you're doing. "Supply and fit Worcester Bosch 30i Combi, remove existing boiler and flue, new pipework to kitchen" is a scope. "New boiler" is not.
- What's included.Labour, materials, VAT if you're registered, any certification you're providing — Gas Safe certificate, NICEIC completion certificate, building control notification. Say what they're getting.
- What's excluded.Making good, skip hire, specialist groundwork, access equipment, any work contingent on opening up existing structure. Write it down. This is the single biggest source of post-job disputes.
- Payment terms.Deposit amount and what it covers, any stage payments for longer jobs, and when the final invoice is due. Vague payment terms lead to slow payment or no payment.
- A start date or lead time.Even a rough window. "Earliest start: week commencing 19 May" is better than silence. It tells the customer you've actually thought about their job, not just fired off a number.
None of this needs to be a formal legal document. A clean one-page PDF or a well-laid-out email covers everything above. The point is that the customer can read it and actually understand what they're agreeing to.
Why Detail Beats Cheap
Customers don't always pick the cheapest quote. That's worth saying plainly because a lot of tradespeople assume they do.
When someone gets three quotes for a job on their house, they're not just comparing numbers. They're trying to work out who they can trust. The price is part of that calculation. But so is how professional the quote looks, whether the scope is clearly written, and whether the person who sent it seems to know what they're talking about.
A more expensive quote that references the specific fittings being fitted, explains the compliance standard being met, or sets out a clear approach can beat a cheaper quote that just says "supply and fit — materials and labour." Not every time. But more often than most tradespeople think.
The customers who always choose the cheapest quote will always find someone cheaper. The customers worth having — the ones who value a tidy job, pay on time, and recommend you to their neighbours — are making a trust decision as much as a price decision. Your quote is part of how you make that case.
This is the same reason a professional-looking website builds credibility with customers before they've even spoken to you. The presentation of your business matters. A well-built trades website and a properly written quote are both doing the same job: showing that you run your business like a professional.
Speed and Follow-Up
Seven tradespeople say they're interested in a job. A few days later, half of them haven't sent a quote. The customer is getting frustrated and starting to wonder what working with them would actually be like.
Speed matters. Not because it's the most important thing, but because it tells the customer something. Sending a clear quote quickly says: I'm organised, I actually want this job, and working with me will probably feel like this.
The follow-up is the bit most tradespeople skip. They send the quote and wait, not wanting to seem pushy. But customers who've asked several people to quote and heard back from two of them are not put off by a polite message a couple of days later. They're waiting for it. Silence reads as lack of interest.
A simple follow-up: "Just checking you received my quote — happy to talk through anything." That's it. Not a sales pitch. Just a confirmation that you're still there and still want the work.
Deposits, Payment Stages, and Expiry Dates
A chunky deposit request can kill a conversion if the quote doesn't explain it. A customer seeing "35% deposit on booking" with no context doesn't know if that's for materials on order, to hold your diary, or just because you want cash upfront. It reads as a risk.
Explain it. "35% deposit on booking — this covers materials ordered specifically for your job and reserves your start date." That's a completely different read. Same number, very different feeling.
For jobs running over a week, stage payments make sense and most customers will accept them. Tie them to visible milestones — first fix complete, second fix complete, snagging signed off — not arbitrary dates. Progress the customer can see and verify is progress they'll pay for without argument.
Always explain what it covers. Materials on order, diary hold, or both. Unexplained deposits kill conversions.
Tie to visible milestones, not calendar dates. First fix, second fix, completion. Progress they can see.
State the due date clearly — "on completion" or "within 7 days of completion." Don't leave it open-ended.
30 days is standard. Material costs move. A quote accepted months after it was sent can leave you badly priced.
Late payment is a persistent problem in UK construction — only around half of Scottish builders report invoices paid within agreed terms. Clear payment terms in the quote are your first line of defence. They set the expectation before any work starts, and they give you something to point to if payment drags.
When to Charge for the Quote Itself
For simple, clearly defined work — fitting a tap, replacing a boiler in a straightforward location, painting a room — a free quote is what customers expect. Going out to assess the job, writing it up, and sending the price is just the cost of doing business for work like that.
For complex, design-heavy, or diagnostic work — an extension that needs drawings, an electrical fault that needs investigation, a bathroom that needs full specification — a "free quote" can mean several hours of unpaid work. That's a different situation entirely.
If you want to charge for a quote, survey, or diagnostic visit, say so before you show up. Not after. A customer who receives an unexpected invoice for a quote they assumed was free will not use you again, and they'll say so publicly. The charge itself isn't usually the problem. The surprise is.
A workable position for most one-man bands: free ballpark on the phone for standard work; paid survey or design time for anything that genuinely requires professional preparation before pricing. Be clear about it upfront and most customers will accept it without complaint.
Mistakes That Cost You Jobs
- No scope, just a total. "Materials and labour — £1,850." No breakdown, no exclusions, no payment terms. Invites a comparison on price alone and creates disputes later.
- Quoting before the scope is mature. Extensions before drawings, rewires before a proper survey, major renovation work with nothing specified in writing. Fixed prices on half-defined jobs are where tradespeople lose money.
- Quote and estimate used interchangeably. If you call it a quote in the subject line and an estimate in the body, the customer will hold you to whichever interpretation suits them.
- No expiry date. A quote that lasts forever is a liability when material costs rise. Thirty days is the standard.
- Unexplained deposit requests. Say what the deposit covers. Always.
- No follow-up. Most customers expect to hear from you after you've sent a quote. Silence reads as disinterest.
- Pricing to avoid a job. Quoting high to dodge awkward work is a gamble — sometimes the customer accepts, and you're stuck on a job you didn't want at a price that doesn't account for why you didn't want it. Decline clearly or price it properly.
- VAT left out. If you're VAT registered, the quote should say whether the price includes VAT or is subject to it. Finding out at invoice stage is a bad experience for the customer.
Keep Track of What You've Sent
Every quote you send is a job you might win. Most tradespeople have no clear view of what's outstanding — quotes sitting in sent folders, jobs they meant to follow up on, customers they half-remember from three weeks ago.
At minimum, keep a simple log: who you quoted, how much, when it expires, and whether you've followed up. A lot of jobs are won just by being the only person who bothered to check in.
If you want something more structured, the portal we're building for GATW customers includes a quoting and job tracking tool built specifically for tradespeople. Raise quotes, track status, follow up on time — without the spreadsheet faff. Get in touch if you want to know when it's ready.
A professional quote is easier to manage when the rest of your business is running cleanly online too. A well-maintained Google Business Profile means the customers landing on your quote already have a good impression of your business before you've sent a word.
Common Questions About Quoting
Does a quote have to be in writing to be binding?
No, but a verbal quote is much harder to enforce in a dispute. A written quote accepted by email or text is a contract. That protects you as much as it protects the customer. Always send something written, even for smaller jobs.
What's a reasonable deposit to ask for?
There's no universal figure, but the key is explaining what it covers. A deposit for materials ordered specifically for the job, or to hold a start date in a busy diary, is entirely reasonable. Customers get suspicious when there's no explanation. Say why you're asking for it and most people will accept it without issue.
How long should a quote be valid for?
Thirty days is the standard for most trades work. Material costs move, your diary fills up, and a quote sent in March that gets accepted in July can leave you badly priced. If a customer comes back after the validity period, you can reissue — but you're not locked in if things have changed.
What do I do if the job turns out bigger than I quoted?
If you gave a fixed quote and the job is simply taking longer than expected, that's normally your problem to absorb. The protection is writing clear exclusions upfront: "this price excludes any remedial work discovered once existing structure is opened." If something genuinely outside scope does appear, agree the variation in writing before doing the extra work. Not after.
Should I quote before or after seeing the job?
For simple, clearly defined work, a phone call and some photos can be enough. For anything involving existing structure, complex layout, or significant specification — see it first. Quoting blind on complex jobs is one of the most common ways tradespeople end up underpriced and stuck.
