How to Write a Quote as a Tradesman UK: What to Include and How to Win More Work (2026)

Quick Answer

A professional tradesman quote must include your contact details, the customer name and address, a clear description of the work with separate labour and materials costs, payment terms, and a 30-day validity period. Always send it in writing within 24 hours of the site visit. A written quote that is accepted by the customer forms the basis of a legally binding contract and gives you full protection if a dispute arises.

A professional written quote is one of the most powerful tools a self-employed tradesman has. It protects you legally, sets clear expectations with the customer, and significantly increases your conversion rate over handwritten or verbal estimates. This guide covers exactly what to include in a tradesman quote, how to structure it, and how to write and send it fast enough to win the job before a competitor does.

Verbal Estimates vs Written Quotes: The Difference

A verbal estimate is not binding and gives you no legal protection whatsoever. If a customer decides at the end of a job that they thought the price was going to be lower, and you only ever discussed it on the doorstep, you have very little recourse. A written quote, once accepted by the customer, forms the basis of a contract. That distinction matters enormously when disputes arise, and they do arise, even with customers who seemed perfectly reasonable at the outset.

Always follow up a site visit with a written quote, even for small jobs. For a job under £200, a brief email summarising the work and the price is sufficient. For anything larger, a properly formatted PDF quote is worth the extra five minutes it takes to produce. The customer feels more confident in you, they have something concrete to refer to, and you have a paper trail if a dispute arises later.

Beyond the legal protection, professional presentation often makes the difference between winning and losing a job to a competitor who gave the same price. A customer receiving a typed, clearly structured PDF quote on headed paper from one tradesman and a WhatsApp message with a number from another will almost always feel more comfortable with the former, even if the figure is slightly higher. You are not just quoting for the work; you are demonstrating how you run your business.

There is also a practical benefit to writing things down. Going through the process of itemising labour, materials, and exclusions forces you to think carefully about the scope. It is much harder to miss something or underprice a job when you have to commit it to paper. Tradesmen who quote verbally tend to give vague numbers that they later regret when the reality of the job costs more than they remembered pricing for.

What Every Tradesman Quote Must Include

A professionally written tradesman quote should cover the following items as a minimum. Missing any of these is a risk, either to your legal position or to the customer relationship.

The exclusions section is the one most commonly skipped, and it is also the one that causes the most problems. If you do not state explicitly that your price excludes making good plasterwork after chasing cables, for example, the customer will assume it is included. Write down everything that is outside your price and you save yourself a great deal of awkward conversation later.

How to Structure a Quote by Trade

The right structure for a quote varies by trade. What matters in every case is that the customer can follow the logic of the price, that the sections correspond to recognisable parts of the job, and that labour and materials are shown separately so neither party is in any doubt about what they are paying for.

Plumbing quotes

Section by location: bathroom, kitchen, airing cupboard. Within each section, list the specific fixtures being installed or repaired, the labour hours for that area, and the materials required. Where you are fitting customer-supplied goods, note this explicitly and state whether your warranty covers installation only. Include the cost of any testing, such as pressure testing a new system before commissioning.

Electrical quotes

Section by circuit or by area of the property. List each circuit, socket run, or lighting circuit separately. Include testing and certification costs as a separate line, and be explicit that the price includes Part P notification and an Electrical Installation Certificate where required. Customers often do not know these costs exist and can be surprised if they appear on the invoice but were not on the quote.

Roofing quotes

Specify the tile or slate type, the underlay specification, and the ridge and valley details. List scaffolding as a separate line item; it is a significant cost and customers need to see it clearly rather than have it hidden in a total. State whether your price includes taking up and disposing of the existing covering. If there is any risk of rotten decking boards being found on strip-off, cover this with an explicit day rate for additional timber works.

Building and groundworks quotes

Separate groundworks from structure from finishes. This matters because each phase has a natural completion point, which makes it easier to tie stage payments to recognisable milestones. Include a contingency allowance of at least 10% on groundworks specifically, since ground conditions can change once you start excavating and no site survey covers every eventuality. Make this allowance visible on the quote rather than hiding it in your margin.

Plastering quotes

List each room and the surface type being plastered: wall area in m2, ceiling area in m2, and whether the work is a skim over existing plaster or a full set on bare blockwork or dot-and-dab board. These have very different labour rates and material requirements. A full set takes significantly longer and uses considerably more material than a skim, so they must be priced separately if both are involved.

Whatever trade you work in, the principle is the same: structure your quote so that removing one section gives the customer a clear view of what that element costs. This is useful both for your own pricing discipline and for any negotiation conversation where a customer wants to phase the work or reduce the scope.

Setting Your Price Correctly

A common mistake is to work out a rough total and then adjust it based on gut feel about what the customer will accept. This approach leads to inconsistent margins and a tendency to undercharge on complex jobs. The correct method is to build the price from the bottom up, starting with your actual costs.

Calculate your quote using this structure: labour hours multiplied by your hourly rate, plus materials at your sell price with a markup, plus any subcontractor costs, plus a contingency of 5 to 10% for complexity and unforeseen minor issues. Your hourly rate needs to cover your van, insurance, tools, tax, and a margin above that. If you are not sure what your rate should be, the hourly rate calculator will work it out based on your actual costs.

Materials markup is a legitimate and necessary part of your price. When you supply materials, you carry the risk of price changes, you spend time sourcing and collecting them, and you take on responsibility for their suitability for the job. A markup of 15 to 25% on materials is standard and fair. For guidance on what an appropriate markup looks like across different scenarios, see the material markup guide for UK tradesmen.

Never quote just to win the job at a price that will not cover your costs. It is better to be the higher quote and lose the job than to win it and work at a loss. When you win a job at too low a price, you end up rushing it to minimise your losses or resenting the customer before you even start. Neither outcome benefits anyone.

If you are consistently losing quotes on price, the answer is rarely to drop your rate. Review whether you are targeting the right customers, whether your quote presentation communicates quality and professionalism, and whether your follow-up process is giving quotes the best chance of converting. For a broader view of how to think about pricing overall, the guide on how to price a job as a tradesman covers the full framework in detail. The profit margin calculator is also useful for checking that the margin on any given quote is actually worth winning.

Sending the Quote and Following Up

Send your quote the same day as the site visit, or at the absolute latest within 24 hours. Customers contact multiple tradesmen simultaneously, which is perfectly normal and entirely sensible from their perspective. Whoever responds fastest and most professionally often wins the job regardless of price. A same-day quote tells the customer you are organised, on top of your workload, and serious about the job. A quote that arrives a week later sends the opposite message, even if the price and quality of work would be superior.

Send the quote as a PDF by email or share it via a link if you are using quoting software. A PDF on headed paper with your logo looks significantly more professional than a typed WhatsApp message or a handwritten note photographed on a phone. It is also easier for the customer to forward to a partner or save for reference. First impressions matter, and the quote is often the first formal document a customer sees from you.

When you send the quote, keep the covering message brief and direct. Something like: "Hi [name], please find attached the quote for the work we discussed on [date]. The quote is valid for 30 days. Please let me know if you have any questions or would like to discuss anything." No hard sell, no pressure, just clarity and professionalism.

Follow up 3 to 5 days later with a brief message asking whether the customer has had a chance to look at the quote and whether they have any questions. This single step converts 10 to 20% of quotes that would otherwise go cold simply because the customer got busy or forgot to respond. Do not wait for the customer to come to you. Most people are not ignoring your quote deliberately; they just have other things going on.

If the quote is declined, it is worth asking politely whether there was a specific reason. Sometimes the answer will tell you something useful: they went with someone they already knew, the specification changed, or they decided to delay the project. Occasionally they will say the price was higher than expected, in which case you can decide whether to offer an alternative scope. What you should not do is reduce the price of the original quote without changing the scope, because that signals to the customer that your pricing was not serious in the first place.

Common Mistakes to Avoid

Most disputes between tradesmen and customers stem from one of a small number of avoidable errors. These are the ones that come up most often.

Quoting without visiting the site first

Always visit the site before committing to a price, if the job is anything more than straightforward. Photos sent by customers rarely tell the full story. Access problems, awkward pipe runs, the condition of the existing structure, and the difficulty of parking and getting materials in all affect your price and cannot be assessed remotely. A quote that is based on a WhatsApp description will almost always turn out to be wrong in some material way.

Being vague about the scope of work

"Bathroom refurbishment" is not a scope of work. "Supply and fit new bath, toilet, basin and shower enclosure; retile floor and walls to existing layout; update extraction fan; supply and fit heated towel rail" is a scope of work. The more specific you are, the less room there is for the customer to argue that something was included when it was not. Vague quoting is the number one source of customer disputes in the trades.

Not including exclusions

If your quote does not include making good after plastering, painting, moving furniture, disposing of old materials, or obtaining permits, say so. Customers are not trying to catch you out: they simply do not know what is and is not standard. A clear exclusions list prevents the "I assumed that was included" conversation, which is never a pleasant one to have when the invoice arrives.

Forgetting to address VAT clearly

If you are VAT-registered, the quote must show whether prices are exclusive of VAT or inclusive of VAT. The safest approach is to show a net subtotal, the VAT amount at 20%, and the gross total. If you are not VAT-registered, do not mention VAT at all. A quote that says "£3,000 + VAT" from a non-registered tradesman is illegal. If you are approaching the £90,000 registration threshold, factor this into your planning and pricing well in advance. For guidance on call-out fees and how VAT interacts with those, see the tradesman call-out fee guide.

Not setting a validity period

Material prices change, your diary fills up, and a site you visited in January may have changed by March. Always include a validity period of 30 days. This protects you from a customer who accepts a quote three months later and expects you to honour the original price. It also creates a natural reason to follow up before the deadline.

Giving a number verbally and not following up in writing

Even if a customer verbally says yes to a price on the doorstep, always follow up with a written confirmation before you start. People misremember numbers, especially when they have been speaking to several tradesmen in the same week. A written confirmation, even a brief email, eliminates ambiguity and gives you both something to refer to.

Frequently Asked Questions

Should a quote be signed by the customer?

For significant jobs over £500, it is good practice to ask the customer to confirm acceptance in writing before you start. An email reply saying "I accept your quote" or "Please go ahead with the work as quoted" is legally sufficient in the UK and creates a clear record of the customer's agreement to the price and scope. For larger projects above £2,000 or £3,000, a formally signed quote or a simple one-page contract is preferable, particularly for customers you have not worked with before. A signed acceptance that references the specific quote document protects you completely if the customer later disputes the price, claims the scope was different, or refuses to pay for work that was clearly within what was quoted. It also makes the debt more straightforward to recover through the Small Claims Court if the worst happens.

How long should a quote be valid for?

State a validity period of 30 days on all quotes, and include this clearly near the top of the document rather than buried in small print at the bottom. Beyond 30 days, material prices may have risen, your diary may have filled up with other work, and the original site conditions may have changed in ways that affect the price. Including a phrase such as "This quote is valid for 30 days from the date above. After this period, we reserve the right to revise the price" sets clear expectations and creates a natural sense of urgency for the customer to commit. It also gives you a legitimate reason to follow up before the deadline and a clear basis for reissuing a revised price if they come back three months later and expect you to honour the original figure.

Do I need to include VAT on a quote?

If you are VAT-registered, you are legally required to charge VAT on your supplies and you should show the net price, the VAT amount at 20%, and the gross total as clearly separate line items on the quote. This avoids any confusion about whether the figure the customer agreed to was inclusive or exclusive of VAT. If you are not VAT-registered, which means your taxable turnover is below the current registration threshold of £90,000, do not charge VAT and do not mention it on the quote at all. Charging VAT when not registered is illegal and can result in serious penalties from HMRC. If you are approaching the VAT threshold and expect to cross it within the next year, this is the time to factor potential registration into your pricing decisions, because the transition will affect your competitive position relative to non-registered competitors.

What should I do if the job ends up costing more than the quote?

If unforeseen work arises that was genuinely outside the original scope, stop work and notify the customer before proceeding with the additional items. The key word here is genuinely: if you missed something on your site visit that a more thorough inspection would have identified, that is your responsibility to absorb, not the customer's. But if you open a wall and find pipework that needs replacing before the new installation can proceed, and that was not visible or identifiable at the quote stage, you have a legitimate basis for a variation. Issue a variation order, a short written note or email describing the additional work and the cost, and get the customer's written agreement before doing the extra work. Never simply complete additional work and add it to the invoice without agreement first, because the customer can legitimately refuse to pay for anything outside the original quoted scope, and you will have limited legal recourse if they do.

How do I handle a customer who wants to negotiate the quote?

Start by understanding what the customer is actually asking before you respond. Do they want a lower price, or do they want something taken out of the scope to reduce the cost? These are very different conversations. If they want to reduce the scope, ask them specifically what they would like to remove and reprice accordingly. This protects your margin entirely and makes clear that your original price was fair for the work it covered. If a customer insists on a lower price for exactly the same scope of work, that is usually a sign that they are price-driven in a way that will not make them a good customer, and it is often better to let that job go than to win it by cutting into your margin. If you want to offer something as a goodwill gesture, you can offer a small discount of around 5% for upfront payment or early settlement, but do not reduce your rate significantly just to win a single job. It sets a precedent and undermines your pricing credibility with that customer going forward.
