What You Need Before You Start Quoting
Before you price anything, you need the right information. Turning up to a job without asking the right questions is like measuring twice and cutting once, then realising you measured the wrong wall. You need to know the full scope of work, the site conditions, who else is involved, and what the customer actually expects to happen, not just what they think they want.
Get the answers to these questions before you produce any figures. What is the exact scope? Are there access issues, asbestos risks, or third-party sign-offs needed? Who is the customer, a homeowner, a landlord, or a business? That last point matters legally. The Consumer Rights Act 2015 applies to contracts with consumers, meaning private individuals not acting in a business capacity. Section 49 of that Act implies a term that all services will be carried out with reasonable care and skill, and you cannot contract out of it. Knowing you are dealing with a consumer rather than a commercial client changes the legal framework you are operating in.
You also need your own numbers sorted before you quote a single job. Know your day rate, your material markup, your overhead contribution per hour, and your minimum job charge. If you do not have those figures, you are not quoting, you are guessing, and guessing is how sole traders end up working at a loss.
- •Full written scope from the customer or your own site survey notes
- •Confirmed customer type: consumer, landlord, or commercial client
- •Access and site condition details including parking, power availability, and working hours
- •Subcontractor or specialist involvement and their costs
- •Any regulatory or compliance work required (notifiable electrical, gas certification, planning, building control)
- •Your up-to-date material prices from your supplier
- •Your own labour rate, overhead recovery figure, and target margin
Step 1: Do the Site Visit Properly
A quote done without a site visit is a guess with a number on it. For any job above a few hundred pounds, go and see it. Take photos, take measurements, and take notes. Walk the job in your head while you are standing there. Where is the boiler going to discharge? Where will the first fix cables run? Can you get the bath panel off or is it tiled in? These are the things that kill your margin later if you have not clocked them at the quoting stage.
While you are on site, look for scope creep triggers. These are the things the customer has not mentioned but which you can already see will need doing or will cause problems. An old consumer unit that will need upgrading before you can run the new circuits. A soil stack that looks cracked. Render that will need making good after the flue goes through. Flag these at the visit, not after you have started the job. If you spot something and stay quiet, you either wear the cost yourself or you have an awkward conversation midway through the work.
A common pitfall at this stage is being too eager to give a number on the doorstep. Customers often ask, and it feels rude not to answer. Give them a ballpark range only if you must, but make it clear it is subject to your written quote. Never commit to a price verbally on site. Under the Consumer Rights Act 2015, if the price is not adequately covered in writing, Section 51 implies the customer pays a reasonable price, which may not be what you had in mind.
Step 2: Calculate Your Costs Without Cutting Corners
Sit down with your notes and work through the job systematically. Split it into labour and materials, and price each separately. For labour, count the hours realistically including travel to the merchants, waiting time for deliveries, and any making-good. Most tradespeople undercount by 20 to 30 percent because they price the best-case scenario rather than the realistic one. Price the realistic one.
For materials, get current prices. Do not work from memory or last year's price lists. Supplier costs have shifted significantly in recent years and a price you quoted on three months ago may now be five to fifteen percent out. Add your material markup on top. A markup of 20 to 30 percent on materials is standard and entirely legitimate. You are sourcing, collecting, transporting, and warranting those materials. That has a cost.
Do not forget your overheads. Insurance, tool replacement, van costs, fuel, phone, software, accountancy, and your own downtime between jobs all need to be recovered across your billable hours. If you work 1,000 billable hours a year and your annual overheads are £12,000, that is £12 per hour you need to add before you make a single penny of profit. Sole traders routinely forget this and wonder why they are busy but not making money.
If CIS applies because you are working for a contractor rather than a direct customer, factor in how the deduction affects your cash flow. Under the Finance Act 2004 and the Income Tax (Construction Industry Scheme) Regulations 2005, contractors must deduct 20 percent (or 30 percent for unverified subcontractors) at source. You will get it back via your tax return, but it affects your working capital in the meantime.
- •Labour hours, multiplied by your realistic day or hourly rate
- •Materials at current supplier prices, plus your markup
- •Plant hire, skip hire, or specialist equipment if needed
- •Subcontractor costs if you are bringing anyone else in
- •Your overhead contribution per hour, calculated from your annual overheads
- •Your target net profit margin on top of all of the above
Step 3: Decide on a Quote, Not an Estimate
There is a legal distinction between a quote and an estimate that most tradespeople either do not know or do not apply. A quote is a fixed price offer. Once accepted, it becomes a binding contract at that price. An estimate is an approximation, and the final cost can vary. Using the wrong word on your paperwork can put you in a difficult position later. If you write 'estimate' but you intend it to be fixed, the customer may expect you to honour a lower number. If you write 'quote' but you know the price will move, you have either got to deliver at that price or negotiate a variation.
For most domestic jobs where the scope is clear, give a fixed quote. It gives the customer confidence and it gives you protection. If the scope is genuinely uncertain, for example remedial work where you do not know what you will find once you open a wall, then quote a day rate with an estimated total, and be clear in writing what triggers additional charges.
A common pitfall here is giving a verbal quote followed by a written confirmation that says something different. If there is a dispute, courts will look at what was communicated and when. Keep your written document as the definitive record. The Limitation Act 1980 gives a customer six years to bring a claim under a contract, so your paperwork needs to be clear and retained.
Step 4: Write a Quote Document That Does the Selling for You
Your quote document is not just a price. It is a sales document, a scope of work, and a legal record all at the same time. A single figure on a text message is not a quote. A proper written document sets you apart from the competition before the customer has even spoken to anyone else.
The document needs to include your business name, address, and contact details, the customer's name and address, the date, a clear description of the work to be done, the price (broken down where possible), what is not included, your payment terms, your cancellation terms, and a validity period for the quote. For domestic customers, you are required under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 to provide certain information before the contract is concluded, including the right to cancel within 14 days if the contract was agreed off-premises, for example at the customer's home. Failing to provide this notice means the cancellation period is extended to 12 months.
Your exclusions section is as important as your inclusions. Be specific. If your bathroom refit quote does not include making good the plasterwork, say so. If it does not include removing and disposing of the old suite, say so. Every ambiguity is a future argument.
On pricing, a line-by-line breakdown gives the customer clarity and makes it harder for them to cherry-pick the cheap parts and get another trade in for the rest. It also demonstrates that you know your costs, which builds trust. You do not have to show your labour rates and margins separately, but breaking it into logical work stages helps.
- •Your full business details including any trade registration numbers (Gas Safe, NICEIC, etc.)
- •Customer name and property address
- •Date of quote and validity period (typically 30 days)
- •Detailed scope of work, written in plain English
- •Clear list of exclusions
- •Total price including VAT if you are VAT-registered
- •Payment terms including deposit amount, stage payments if applicable, and final payment due date
- •14-day cancellation rights notice for off-premises domestic contracts
- •Your terms and conditions or a reference to where they can be found
Step 5: Price to Win Without Racing to the Bottom
The most common mistake tradespeople make when pricing is assuming the lowest price wins. On some jobs with some customers, it does. But most domestic customers are not actually shopping purely on price. They are shopping on trust, clarity, and confidence that the job will be done right. A well-written quote from a professional-looking sole trader at a slightly higher price will beat a scribbled number from someone who looks disorganised, most of the time.
Position your price with brief explanations of value where it helps. Not marketing waffle, but practical statements. 'Price includes full certification and notification to building control under Part P of the Building Regulations 2010.' That one sentence tells the customer you know what you are doing and that the job will be legal and insurable, which matters enormously to homeowners who are planning to sell or remortgage.
If you are significantly more expensive than what the customer expects, do not hide from it. Address it directly in a covering note or when you present the quote. Explain what is included, what the certification covers, how long the work will take, and what guarantee you provide. Customers who go with the cheapest and get burnt come back to the professional. Make it easy for them to choose you first.
A common pitfall is discounting to win work without adjusting the scope. If you must move on price, take something out of the scope rather than cutting your margin. Offer to remove the old materials at cost rather than included. Offer a staggered payment plan. Never just knock money off without a reason, because it tells the customer your original price was inflated and that you can be negotiated down further on the next job.
Step 6: Set Out Your Payment Terms Clearly
Payment terms are not an afterthought. They are part of the contract, and vague payment terms lead directly to late payment disputes. Be specific. State the deposit amount (typically 25 to 40 percent for larger jobs), when stage payments fall due, and when the final balance is payable. For larger residential or commercial projects, you may want to use stage payments tied to completion milestones, which is consistent with the Housing Grants, Construction and Regeneration Act 1996, which provides rights to stage payments on construction contracts above a de minimis threshold.
State your due dates clearly. 'Payment due on completion' is fine for smaller jobs. For anything over a week's work, break it into stages. State that ownership of materials does not pass to the customer until full payment is received. This is a retention of title clause and it protects your materials if a customer defaults before the job is finished.
If you are dealing with a late payer, you have statutory rights under the Late Payment of Commercial Debts (Interest) Act 1998. For business-to-business debts, you can charge interest at 8 percent above the Bank of England base rate from the day after the payment was due. You can also claim fixed compensation of £40 for debts under £1,000, £70 for debts between £1,000 and £9,999, and £100 for debts of £10,000 or more. Note that this Act applies to business-to-business contracts. For consumer contracts, your contractual interest terms govern instead.
For VAT-registered tradespeople working as subcontractors on construction projects, check whether the domestic reverse charge applies under VAT Notice 735. Introduced in March 2021, the domestic reverse charge means that in certain construction supply chains, the VAT is accounted for by the customer rather than the supplier. Getting this wrong leads to HMRC penalties, so if you are unsure, speak to your accountant before quoting.
Step 7: Follow Up Without Being Pushy
Sending the quote and waiting in silence is not a strategy. Most customers do not respond immediately, not because they have gone elsewhere, but because life gets in the way. A single follow-up call or message three to five days after sending the quote is professional and expected. Keep it brief. Ask if they have had a chance to look at it, whether they have any questions, and whether they would like to go ahead.
If they are comparing quotes, which most customers do on larger jobs, your follow-up is an opportunity to reinforce the value in your quote, not to lower the price. If they raise concerns, answer them honestly. If they mention a lower competitor quote, do not immediately match it. Ask what is included in the other quote. Often the cheaper price covers less, or the other tradesperson has not included materials, VAT, or certification.
Set a validity period on your quote, typically 30 days, and mention it gently during the follow-up. Material prices move and your diary fills. A validity period is not a pressure tactic, it is a practical statement of fact. If 30 days pass and the customer comes back, you are entitled to requote based on current material prices.
A common pitfall is following up too aggressively or too many times. One follow-up call and one follow-up message is enough. If they have gone with someone else, let it go and move on. Not every job is worth winning, and chasing an unresponsive customer wastes time you could spend winning better ones.
Step 8: Know the Legal Bits That Protect You Once the Job Is Accepted
Once your quote is accepted, you have a contract. Under the Consumer Rights Act 2015, Section 49, you are legally obliged to carry out the service with reasonable care and skill. Section 52 implies a term that the service will be carried out in a reasonable time if no time was fixed. That is why your quote should state an estimated start date and completion timeframe, even if approximate. It protects both parties and avoids the customer having unrealistic expectations about when their kitchen will be finished.
For notifiable electrical work under Part P of the Building Regulations 2010, you must notify the work to a competent person scheme or to local building control before carrying it out, unless you are registered with an approved scheme. Failing to notify is a criminal offence and can result in improvement notices, fines, and problems for the homeowner when they sell the property. Include your scheme registration number on your quote and confirm in writing that the work will be notified and certificated.
Gas engineers working on gas fittings must be Gas Safe registered under the Gas Safety (Installation and Use) Regulations 1998. Regulation 36 requires a Landlord Gas Safety Record (CP12) to be issued after inspection of gas appliances in rented accommodation. If your quote involves gas work in a rental property, confirm in writing that you will issue the appropriate certification. This protects you and demonstrates to the landlord that you understand their legal obligations.
For larger projects, be aware of the Scheme for Construction Contracts (England and Wales) Regulations 1998, which provides default payment and adjudication terms where the Housing Grants, Construction and Regeneration Act 1996 applies but the parties have not agreed their own terms. If you are working on a construction project worth more than a few thousand pounds, having your own clear payment terms in writing is essential, otherwise the Scheme's default terms may apply and they may not suit you.
Worked Example: Bathroom Refit Quote from Start to Finish
Here is a realistic worked example. Gary is a sole-trader plumber based in Leeds. A homeowner contacts him about a full bathroom refit. Gary visits the property on a Tuesday, takes measurements, photographs the existing layout, and notes that the existing pipework is in poor condition and will likely need partial replacement. He identifies that the customer is a homeowner (consumer, not commercial) and that the job is entirely within the existing bathroom footprint so planning permission is not required.
Gary calculates his costs as follows. Labour: 3 days at £280 per day, total £840. Materials: new suite, tiles, adhesive, grout, pipe fittings, waste fittings, sundries, total at cost price £1,150. Gary applies a 25 percent materials markup, bringing the materials total to £1,437.50. He identifies that he will need to hire a tile cutter for one day at £45. His overhead contribution at £15 per hour for 24 hours is £360. He wants a 20 percent net profit margin on top of all costs. His total cost base is £840 plus £1,437.50 plus £45 plus £360, which equals £2,682.50. His 20 percent margin on cost is £536.50, giving a total quote price of £3,219, which he rounds to £3,200 excluding VAT. Gary is not VAT-registered, so no VAT applies.
Gary sends a typed quote document on headed paper the following day. The document includes his full name, trading name, address, mobile number, and his Gas Safe registration number (included even though this is a plumbing job, because it builds credibility). The quote is dated and valid for 30 days. It sets out the full scope in plain English across six bullet points. Exclusions state clearly that wall tiling to areas outside the shower enclosure, electrical work, and structural repairs are not included. Payment terms state a 30 percent deposit of £960 on acceptance, a stage payment of £1,280 when the first fix is complete, and the balance of £960 on completion. The quote includes a paragraph notifying the customer of their right to cancel within 14 days of acceptance under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, because the contract was agreed at the customer's home.
Gary follows up by phone on the Friday, three days after sending the quote. The customer says she has one other quote which is £2,600. Gary asks what it includes. It turns out the other quote does not cover making good the tiling after the waste pipe replacement and does not include the tile cutter or the materials markup transparency Gary had provided. Gary explains this briefly without criticising the competitor, and the customer accepts Gary's quote the following Monday. Job won at £3,200. Gary's margin covers his overheads and leaves him with a realistic profit on the work.
How TradeDoc Can Help You Quote Faster
Putting together a properly structured quote document from scratch takes time, and it is often the last thing you feel like doing after a day on site. TradeDoc (tradedoc.co.uk) is a tool built for UK sole-trader tradespeople that generates professional quote documents in around two minutes. You enter your job details, your pricing, and your terms, and it produces a formatted document you can send straight to the customer.
It handles the legal requirements automatically, including the Consumer Contracts Regulations cancellation notice for domestic off-premises contracts, so you do not have to remember to include it every time. For tradespeople who are sending multiple quotes a week, the time saving is significant and the consistency across documents protects you legally.
It is not a replacement for knowing your costs or doing a proper site visit. Those parts are still on you. But the document itself, the thing the customer reads and judges you on, can be done properly without spending half an hour at the kitchen table every evening.
