How to Read a Tradesperson Quote. And Not Get Caught Out.
Key Takeaways
A quote is legally binding once accepted. An estimate is not. Always get a quote in writing and the most detailed quote is usually the most reliable, not the cheapest.

Quote vs estimate: the difference that actually matters
A quote (or quotation) is a fixed price for a specific piece of work. Once you accept it, it becomes a legally binding contract under UK law. The tradesperson must complete the work for the price stated, unless you agree to changes in scope.
An estimate is a ballpark figure. It's non-binding, can change without prior agreement, and offers very limited legal protection if the final bill comes in significantly higher.
A tradesperson can technically give you a verbal quote, and it may still be enforceable, but verbal quotes are extremely difficult to prove in a dispute. Always get it in writing. Always.
What a tradesperson quote should include
A professional, trustworthy quote is a document you can hold someone to. Here's what should appear:
- Tradesperson's full details: Name, trading name, company address, phone, email.
- VAT number: Required if VAT registered. If VAT is being charged without a number, that's a red flag.
- Your details: Your name and property address.
- Quote reference and date: Essential for correspondence and any future dispute.
- Detailed scope of works: The most important element. A proper scope specifies every task, the materials to be used, and what the finished result will look like.
- Labour costs broken out: This is the day rate × days budgeted, or a fixed labour fee.
- Materials itemised with specifications: Unspecified materials can mean low-quality substitutions.
- Exclusions explicitly stated: On complex jobs, its absence leaves room for extras.
- Timeline: Estimated start date and duration.
- Payment terms: Deposit amount, stage payments, final payment trigger.
- Public liability insurance: Ask for the certificate if not mentioned.
- Workmanship warranty: Reputable tradespeople will offer at least 12 months.
- Acceptance field: Space for both parties to sign and date. Without this, the quote is a document, not a contract.
What Hey Alfie homeowners get wrong about their quotes
Here are some common misconceptions that come up consistently that are worth addressing directly.
"I need to contact the tradesperson directly to discuss price or scope."
You don't. That's what Alfie is for. If you have questions about the cost breakdown, want to explore a cheaper materials option, or need to query something in the scope, just ask me. I'll go back to the tradesperson, get the answer or a revised figure, and bring it back to you.
"The cheapest quote is the best deal."
Not in our experience. The cheapest quote is often the least detailed one and a quote without a breakdown is one where you'll discover the missing items mid-job, not before it starts.
"The quote is just an estimate, the final price will probably be different."
Every quote from a Hey Alfie trusted tradesperson is a fixed-price quote, not a ballpark estimate. The Hey Alfie Guarantee (T&Cs apply) backs that commitment up.
"If something goes wrong after the job, I have no recourse."
You do. Every job is covered by our £1,000 Hey Alfie Guarantee, with options up to £5,000 for Premium members (T&Cs apply). Aftercare protection runs for three months after job completion.
"The price is fixed, full stop, nothing can change it."
For straightforward jobs with a clear scope, yes. But if a tradesperson uncovers genuinely unforeseen conditions mid-job, the scope may need to change. With Hey Alfie, you'll always be notified before any additional cost is agreed. Nothing is charged without your approval.
Decoding the cost breakdown: what you're actually paying for
Understanding the line items of a scope of work is what separates a homeowner who gets fair value from one who pays over the odds or gets a nasty surprise.
Labour
Usually the largest single cost. Some tradespeople quote a day rate (typically £150–£350/day depending on trade and region); others quote a fixed fee for the whole job. Fixed labour is generally better for you, it removes the incentive to drag the job out.
Materials
Most tradespeople mark up the cost of materials, typically by 15–30%. This is standard practice and entirely legitimate. But it matters when a quote says "materials as specified" without itemising them. Always ask for materials to be listed separately so you can see what spec you're being quoted for.
VAT
Standard rate is 20%. However, some work qualifies for a reduced 5% VAT rate, notably energy efficiency improvements such as insulation, solar panels, and heat pumps. If a tradesperson is not VAT registered, they cannot legally add VAT to your bill.
Additional costs to check for
- Skip hire or waste disposal: often excluded from the headline price, even on jobs that generate significant waste
- Scaffolding: for any work at height, this can add hundreds or thousands to the cost
- Permit and notification fees: e.g. highway licences, Part P notifiable electrical work, or Building Regulations sign-off
Trade jargon decoded
Prime cost (PC) sum: a provisional allowance for materials you'll choose yourself (e.g. tiles, sanitaryware). The tradesperson sets a budget; if you choose something more expensive, the quote price increases accordingly.
Provisional sum: an allowance for work that can't yet be fully scoped, usually because it depends on what's found once work starts. These should always be clearly labelled and explained upfront.
Day works: work charged at a daily or hourly rate rather than a fixed price. Usually used for unforeseen extras. If day works appear on a quote before work has started, ask why that element can't be scoped and priced properly.
Red flags to watch for before you sign
Research published in 2025 found that only 26% of homeowners aged 18–29 said they'd never had a problem with a tradesperson, compared to 55% of over-60s. Knowing what to look for is a reasonable substitute for experience.
- No written quote offered. A tradesperson who insists on verbal only, or sends a single figure with no breakdown, is giving you nothing to hold them to.
- No company address. Every legitimate trade business has a registered address. A phone number and a first name is not enough.
- No mention of insurance. Ask before you accept. If they can't produce a public liability certificate on request, don't proceed.
- Vague scope of works. Ambiguity in the quote is ambiguity in the job and you'll pay for it later.
- One quote significantly cheaper than all others. According to Zoopla, this often signals low-quality materials, a misunderstanding of scope, or a deliberate low-ball to win the work and charge extras later.
- High-pressure tactics. "I can only do this week" or "price only valid 24 hours" is designed to stop you doing your due diligence.
- Large upfront cash deposit. Anything over 25 to 30% upfront is unusual for most jobs, according to the Contractor Protection Association. Cash only requests remove the paper trail entirely.
- A cash for discount offer. If a tradesperson offers a discount in exchange for cash to keep turnover below the VAT threshold, they're asking you to participate in tax evasion.
- No mention of warranties. A tradesperson confident in their work stands behind it.
How to compare multiple quotes properly
The comparison of quotes is rarely as simple as looking at the bottom line, and treating it that way is where most homeowners go wrong.
"The single biggest mistake when comparing quotes is assuming they're all pricing the same job. They often aren't." - Alfie
Before you compare prices, confirm that every quote:
- Is priced against the same written brief or scope of works
- Specifies equivalent material grades and brands
- States the same exclusions (or lack of them)
- Covers the same start and end point of the job
For example, a quote that's £800 cheaper may have excluded scaffolding if you are doing exterior house work. A quote that looks expensive may include significantly better materials, sometimes you might not need that. The most detailed quote, not the cheapest, is usually the most reliable indicator of what the job will actually cost.
Also check quote validity. Most quotes are valid for 30–90 days. Materials prices, particularly timber, copper, and insulation, have fluctuated significantly in recent years. A quote issued in January may not be honoured in April if you don't move quickly.
Can you negotiate a tradesperson quote?
Yes. And it's more normal than most homeowners assume.
A quote is the opening of a conversation, not a take-it-or-leave-it position.
What's typically negotiable:
- Labour rate: particularly for longer or multi-phase jobs
- Materials specification: there's often a quality tier below the default spec that still meets the job requirement and costs less
- Payment timing: offering to pay promptly sometimes creates room for a small reduction
What isn't negotiable:
- VAT: if they're VAT registered, it's a legal requirement on the invoice
- Insurance overheads: these are fixed costs
- Their minimum margin: a tradesperson who quotes too low will either cut corners or come back for more mid-job
The most effective way to negotiate is to ask for a breakdown if one wasn't provided, then identify the specific line you want to discuss. "Can we look at the materials cost here?" is a far more productive conversation than "can you do it cheaper?"
Deposits, payment terms and your rights
A 25% deposit is the standard and safest benchmark.
According to the Contractor Protection Association, you should never pay more than 25% of the total job value, or £7,500, (whichever is lower) upfront. If a tradesperson asks for 50% or the full amount before work begins, that's outside standard practice.
For large projects, stage payments tied to defined completion milestones are best practice. A typical structure can be: 25% on start, 25% at first fix, 25% at second fix, 25% on satisfactory completion.
Under the Consumer Rights Act 2015, services must be performed with reasonable care and skill. Once you've accepted a fixed quote, a tradesperson can only charge more than the agreed amount in three specific circumstances:
- You request additional work outside the original scope
- Genuinely unforeseen conditions are discovered mid-job and you agree in writing to the additional cost before the work proceeds
- There was a genuine clerical error in the original calculation
Always get any agreed variation confirmed in writing before the additional work starts. Keep everything: quotes, emails, texts, receipts, and invoices. If a dispute arises, your paper trail is your evidence.
Frequently asked questions
How big of a problem are rogue tradepseople in the UK?
The scale of the problem is significant. Cowboy builders alone have cost British homeowners a staggering £14.3 billion over the past five years, according to the HomeOwners Alliance. And research from TrustMark found that incompetent tradespeople cost UK homeowners £1.9 billion in a single year. It's better to be safe than sorry.
Is a tradesperson quote legally binding in the UK?
Yes. Once you accept a written quote, it becomes a legally binding contract. The tradesperson must complete the work for the stated price, unless the scope changes and you agree to any additional cost in advance.
What's the difference between a tradesperson quote and an estimate?
A quote is a fixed price, legally binding once accepted. An estimate is a non-binding approximation that can change. Always ask for a quote, not an estimate, before agreeing to any work.
How many quotes should I get for a home improvement job?
At minimum, three. And all three should be priced against the same written brief. Without that, you're comparing different interpretations of the job, not different prices for the same one.
Can a tradesperson charge more than their quote?
Only in three circumstances:
- You've asked for additional work outside the original scope
- Genuinely unforeseen conditions are discovered and you agree in writing before they proceed
- There was a genuine clerical error in the original calculation
What's a fair deposit to pay a tradesperson?
No more than 25% of the total job value as a starting payment, according to the Contractor Protection Association. Anything above 50% upfront for straightforward work is a warning sign.
What should I do if a tradesperson quote seems too high?
Ask for an itemised breakdown if you don't have one. Identify the specific line item you want to discuss. A specific question gets a useful answer; "can you do it cheaper?" rarely does.
How long is a tradesperson quote valid for?
Typically 30–90 days, after which materials costs may have changed. The validity period should be stated on the quote itself.
