A decorator finishes a two-room job. He'd worked the price out at the kitchen table over a coffee and written £500 on a sheet of paper before walking out. Final invoice, £550 — he'd forgotten to include the woodwork primer. The customer points at the original number and says she's only paying the £500. He absorbs the £50, mutters about it for a week, and tells himself he'll be more careful next time.

He thinks the issue is that he forgot the primer. The actual issue is that he wrote the word "quote" at the top of that sheet instead of "estimate". One word. Big difference.

Most UK tradespeople use these two words interchangeably. Most customers do too. Then a price moves and a dispute starts and someone ends up out of pocket. Here's what each word actually means in the UK, what the law says when there's a row about it, and the phrases that get one-man bands in trouble without them realising.

The Short Answer

Citizens Advice, in both England and Scotland, is direct about it. A quote is a fixed price. An estimate is the trader's best guess. A trader cannot charge more than a quote unless the customer asks for extra work, or the trader explains extra work is needed and the customer agrees to pay for it.

Translated for the tools:

The thing most tradies miss is that the word at the top of the document is what determines whether the price is allowed to move later. Get that wrong and you're either eating costs you didn't expect, or having an awkward conversation when the customer pulls out their phone and shows you a screenshot.

Why Customers Get This Confused (and Why It Bites You)

Most homeowners use "quote" to mean any kind of price. "Quote me for the bathroom" usually means "give me a number for the bathroom". They're not making a legal distinction. They want to compare three traders and pick one.

Section 50 of the Consumer Rights Act 2015 is the bit that tradies almost never know about. In plain English: anything you say or write to the customer can become a contract term if the customer relied on it when deciding to go ahead. So a verbal "shouldn't be more than £600" while you're standing in the kitchen counts. A WhatsApp "I reckon about £4k" counts. A line on a scrap of paper that says "quote: £500" counts.

That's why "rough quote" doesn't really exist as a legal idea. It's either a fixed price or a guess with assumptions. Calling it both at once is what gets people in court.

Worth knowing: in the UK around 14,000 small businesses close every year because of late payments and disputes. Material costs in late 2025 were still rising — the all-work index was up about 3% year on year, with imported timber up around 7-8%. A quote written for one set of conditions and accepted six months later has eaten right through your margin before you've turned up.

When You Should Use the Word "Quote"

Use "quote" when you've actually seen the job, the scope is clear, and you can price it confidently. That generally means:

If those are all true, write "QUOTE" at the top, fix the price, and stand by it. Add a validity date so the number doesn't sit open forever. Add a payment schedule. State what's included and, more importantly, what isn't. Add a written process for changes — that's a "variation" — so if the customer asks for an extra socket or a different tile halfway through, you've already agreed how that gets priced and signed off.

For the full breakdown of what goes inside the document — sections, scope wording, payment terms, validity dates — there's a separate guide: how to write a quote that wins the job. This article focuses on getting the word right in the first place.

When You Should Use the Word "Estimate"

Use "estimate" when something genuinely isn't known yet. That's not a cop-out. It's an honest signal to the customer that the final figure may move, and a real protection for you when it does.

An estimate is not a "charge whatever you like" card. The final price still has to be reasonable, and you still need a paper trail that explains why it changed. The protection comes from naming the assumptions on the page itself: "estimate based on assumption that battens are sound. If they need replacing, additional cost is £X per metre, agreed in writing before that work begins." That's the bit that turns an estimate from a hopeful number into a defensible one.

The Phrases That Get One-Man Bands in Trouble

A short list of wording I'd cut from every tradesperson's vocabulary and every quote template:

None of this is theoretical. A pricing dispute on an extension, a £15k argument over an undercharged build, a decorator who added £50 because he forgot something — they all start with one of these phrases or with no phrase at all because nothing was written down. The fix in every case is the same: write it down, date it, and pick the right word at the top.

The Bit Most Tradespeople Don't Know: 14-Day Cancellation

This one catches almost everyone. Under the Consumer Contracts Regulations 2013, if you accept a job at the customer's home, by phone, by email, by text, online, or anywhere away from your usual trade premises, the customer has a 14-day right to cancel.

That's most trade jobs. Almost no homeowner walks into a tradesperson's office and signs a contract there. They text. They sign at the kitchen table. They click accept on an emailed quote. All of that triggers the 14-day window.

Two things flow from that:

The bigger trap is that if you never even tell the customer they have a 14-day cancellation right (the regulations require you to provide that information in a "durable" form), the cancellation period can be extended by up to a year. A customer can come back nine months later, cancel, and ask for their deposit back.

It sounds onerous. The fix is a single paragraph on every quote that says: "You have 14 days to cancel this contract from the day you accept it. If you would like work to begin within that period, please confirm in writing that you understand you may be charged for any work carried out up to the point of cancellation." Done. Move on.

What Happens When Material Prices Move

Construction materials in the UK have been moving steadily up for the last few years. Bricks, blocks, timber, plumbing fittings, electrical components — pick any of them and the November 2025 number is materially different from the May 2024 one. A fixed quote written today and accepted in three months is exposed unless you've protected yourself.

Three protections, in plain English:

None of this needs a solicitor. It needs a paragraph in your quote template that you write once and never touch again.

A Plain-English Rule

If you can see the job, the scope is clear, and you can price the materials with confidence — write "QUOTE", fix the price, add a validity date, list inclusions and exclusions, set out a written variation process. That's the right word.

If parts of the job are genuinely unknown — hidden behind plaster, under floors, dependent on a third-party survey, exposed to volatile material prices — write "ESTIMATE", state your assumptions, give a range rather than a single number, and explain what would convert it to a fixed quote. That's also the right word.

What you should never do is write "quote" then try to argue afterwards that you meant something looser, or write "estimate" and try to bind the customer to it as if it were fixed. The word at the top sets the rules for the whole job. Pick it deliberately.

And when the customer is comparing your number against two others on her phone, the website is part of how she decides whether you're worth ringing for the survey in the first place. What you put on your trades website is the start of that conversation. The quote document is where it lands.

Common Questions

Is a verbal quote legally binding in the UK?

A contract can be formed verbally, and if you've called your number a "quote" the customer can usually hold you to it. Section 50 of the Consumer Rights Act 2015 means anything you say or write that the customer relied on when deciding to go ahead can become a contract term. Always confirm price and scope in writing on something the customer can save — text, email, PDF, or a portal message.

Can I charge more than my quote if I find unexpected problems?

Only if the customer agrees to the extra work in writing before you do it. Without that, you've fixed a price for the job as you defined it. Anything you didn't see coming is your problem unless you specifically excluded it. The clean fix is to either price the job as an estimate with named assumptions, or quote it with a tight scope and a written variation process for changes.

How long should a trades quote stay valid?

Twenty-eight days is a sensible default. Sixty days for bigger jobs where the customer needs time to decide. With UK construction material costs still moving, anything longer is asking for trouble. Always put the validity date on the document itself, not just in the email body.

Do trades quotes need to include VAT?

For homeowner jobs, yes. If you're VAT-registered, prices shown to consumers must be VAT-inclusive. Quoting "plus VAT" to a homeowner is a breach of consumer pricing rules. For business-to-business work, you can quote ex-VAT as long as it's clearly marked, and you'll need to flag whether the domestic reverse charge applies.

Can a customer cancel after accepting my quote?

Yes, if the contract was made off-premises or at distance — that means accepted in the customer's home, by phone, email, text, online, or anywhere away from your usual trade premises. They have a 14-day cancellation right. If they want you to start within that window, you need their explicit consent in writing on something they can save. Without that, if they cancel mid-job you may have to refund the deposit and absorb the materials cost.
