How to Price a Job as a Self-Employed Tradesman UK: A Step-by-Step Guide for 2026

Step 1: Visit the Site Before Quoting

Never quote from a phone description or an email alone. Visit every job before pricing, even for what sounds like a simple job. It costs you 30 to 60 minutes but protects you from the single biggest source of pricing errors: inaccurate information about the site and the scope of work.

On site, you will discover access issues that affect labour time, for example a loft conversion with a narrow hatch that makes carrying materials up significantly slower, or a rear extension where the only access for a skip is through the house. You will also spot existing materials or conditions that need addressing before you can start, such as damp, asbestos-containing materials in older properties, or non-standard fittings that require adaptors.

Scope differences are extremely common. A customer might describe a "small rewire" but on inspection the consumer unit is non-compliant, the earthing arrangement is inadequate, and there are two additional circuits not mentioned. Conversely, what sounds like a full bathroom refit sometimes turns out to be a straightforward like-for-like replacement that takes half the time anticipated.

The site visit also gives you a chance to assess the customer. Are they organised and clear about what they want, or are they vague and likely to keep changing their mind mid-job? Do they have realistic expectations about timescales and cost, or are they fishing for a cheap price after already getting a quote they found too high? These impressions matter when you are deciding whether to quote at all and at what margin.

If a customer refuses a site visit for a significant job, treat that as a warning sign. Either they are shopping for the lowest possible number without regard for accuracy, or they have something to hide about the condition of the property. In both cases, any quote you give without seeing the job is a guess, and a guess always favours the customer at your expense.

Step 2: Calculate Labour Hours Accurately

Labour is usually the largest single component of your quote, and it is also the most commonly underestimated. The key discipline here is to break the job down into individual tasks and estimate each one separately rather than arriving at a rough total figure for the whole job.

For example, if you are quoting to install a new bathroom, break it into: strip out and disposal, first fix pipework, fitting the bath, fitting the toilet, fitting the basin and vanity unit, tiling, second fix and testing, and snagging. Estimating each task individually will almost always produce a higher and more accurate total than estimating the job as a whole, because it forces you to think about each operation in turn rather than relying on a general impression.

Once you have your task-by-task breakdown, add 10 to 15% to the total to account for minor complications, additional trips to the merchant, time spent talking to the customer, and general admin overhead that belongs to the job but is hard to itemise. This contingency is not padding: it reflects reality on almost every job.

Multiply your estimated hours by your target hourly rate. If you work from a day rate, convert it to an hourly figure by dividing by your productive hours per day, which is typically 6 to 7 hours, not 8. The difference matters: if your day rate is £280 and you assume 8 productive hours, your hourly rate appears to be £35. But if you only bill 6.5 productive hours, your real rate is £43. Use the realistic figure when checking whether your quote stacks up. Our hourly rate calculator can help you work out the right figure based on your actual costs and targets.

Do not forget travel time if the job is out of your usual area. Travel is a genuine cost of doing the job and is entirely reasonable to include in your labour calculation. If you are driving an hour each way to reach a site, that is two hours of your day that belong to this job and should be reflected in the price.

Step 3: Price Materials at Your Sell Price

Materials need to be priced at your sell price, not your cost price. This is a point many newer sole traders get wrong, either because they feel awkward about marking up materials, or because they assume the customer will check and push back. In practice, a reasonable markup on materials is entirely standard in every trade and reflects the real costs you incur in sourcing, collecting or ordering, managing, and warranting the materials.

List every material the job requires and find the trade price for each item. Do this properly: check current prices at your merchant rather than relying on memory, especially for materials like copper pipe and fittings, timber, or cable where prices can shift significantly from month to month in 2026.

Apply your markup on top of trade cost. A typical markup range is 15 to 25%, with the higher end applied to specialist items, items that require additional handling, or materials with a high risk of waste or breakage. On top of the markup, add a wastage allowance of 5 to 15% depending on the material: tiles typically need 10 to 15% wastage for cuts and breakages, paint needs 10%, cable might need 5 to 10% for drops and offcuts.

For jobs where you cannot determine exact quantities until work starts, for example when you are opening up a wall and do not yet know the extent of the pipework replacement required, use an allowance figure and make this explicit in your quote. A phrase like "materials allowance based on visible scope; actual cost adjusted at completion" is clear and protects you. If the job ends up cheaper, the customer benefits; if it runs over, you are not absorbing the difference. Our material markup calculator can help you work out the right sell price for any material.

One practical tip: keep a copy of your quote materials list so that when the job is done, you can compare what you quoted against what you actually spent. Over a few jobs, this gives you real data to refine your wastage estimates and markup levels.

Step 4: Add Overhead and Profit

Overhead is a real cost of running your business that many sole traders either forget to account for or treat as something they absorb personally rather than recover through their pricing. This is a significant and common mistake. If your overhead costs are not built into your quotes, you are subsidising your customers from your personal income.

Overhead costs include: van finance or leasing payments, vehicle insurance and road tax, fuel not directly attributable to specific jobs, tool replacement and maintenance, public liability insurance, professional memberships and certifications (Gas Safe, NICEIC, NAPIT, CHAS, etc.), phone and data, accounting and bookkeeping fees, any trade association fees, PPE and workwear, and any advertising or marketing spend.

To calculate your overhead rate, add up all annual overhead costs and divide by your total billable hours in a year. For a sole trader working 46 weeks with 6 billable hours per day and 5 days per week, that is roughly 1,380 billable hours annually. If your annual overheads total £20,000, your overhead recovery rate is approximately £14.50 per billable hour, which should be added on top of your direct labour cost.

As a rough guide, overhead recovery typically adds 20 to 30% on top of direct labour cost for a sole trader. On top of overhead, add your profit margin. Profit is not the same as overhead recovery: it is the return for the risk you take as a business owner and funds growth, investment in tools, and your buffer against slow periods. A reasonable profit margin for trade work is 5 to 20% depending on competition, the complexity of the job, and demand in your area. Use our profit margin calculator to see how margin affects your final price and net return per job.

Many tradesmen find it easier to build overhead and profit into their day rate or hourly rate rather than adding them as explicit line items on a quote. Either approach works as long as the total reflects all costs. What matters is that you know your numbers.

Step 5: Check Your Quote Covers Your Minimum Rate

Before you send any quote, carry out a quick sense-check to make sure it stacks up against your target rate. Take the total labour portion of the quote and divide it by the estimated labour hours. The result is your effective hourly rate for this job.

If the effective hourly rate is below your target, you have one of two problems: either you have underestimated the hours, or you have underpriced the labour. Both are common and both are fixable before the quote goes out. Go back through your task breakdown and check whether any items look optimistic. If the hours look right, increase the labour rate to bring the effective hourly figure up to your target.

This check is also useful when you are under pressure to match a competitor's price. If you know your minimum rate is £38 per hour and matching the other quote would require you to work at £29 per hour, declining the job is the rational decision. Winning a loss-making job is worse than not winning it: you spend days at site earning below your costs while missing other opportunities.

Some tradesmen use a job costing tool to run this check automatically as part of building the quote. Our job costing calculator lets you enter hours, materials, and overhead to see the effective rate and total profit in real time before you commit to a price.

Getting into the habit of running this check on every quote, even ones that feel obviously profitable, will catch underpricing before it costs you. Most tradesmen who discover they have been undercharging find the problem in jobs that felt straightforward rather than the complicated ones they took more care with.

Step 6: Include Exclusions and Contingencies

A quote without a clear exclusions section is a liability. Whatever is not explicitly excluded will eventually be claimed by a customer as something you should have included. Writing exclusions is not about being difficult: it is about being precise so that both you and the customer agree on exactly what the job covers before any work starts.

Common exclusions for most trades include: redecoration after works (making good plaster is often included, but painting and wallpapering should be explicitly excluded unless quoted separately), disposal of waste materials if this is not in scope, work outside normal hours, any structural or hidden work not visible until existing materials are removed, and work that is dependent on other trades completing first.

For electricians specifically, it is worth excluding: making good walls and ceilings after chasing, any upgrading of earthing or bonding not listed in the quote, and any remedial work to the existing installation beyond what is described. For plumbers, commonly missed exclusions include: drain clearance where blockages are found once work starts, removal of existing concealed pipework in poor condition, and any groundwork or structural alterations required to reroute pipes.

A well-written exclusions section combined with a clear scope description prevents the vast majority of invoice disputes. Customers who dispute invoices almost always do so because the final cost exceeded what they expected, and the most effective way to manage expectations is to be explicit upfront. See our guide on how to write a quote as a tradesman for templates and wording you can use.

Contingency provisions are separate from exclusions. Where scope is uncertain, for example when you are opening up old floors, walls, or roofs and do not know what you will find, include a contingency allowance in the quote and state it clearly. Something like "a contingency allowance of £350 has been included for unforeseen conditions; this will be fully itemised and any unused portion credited at completion" is both transparent and commercially sound.

Common Pricing Mistakes to Avoid

Even experienced tradesmen fall into recurring pricing traps. Being aware of them in advance is the easiest way to avoid them.

• Quoting from memory on materials. Material prices change constantly, and quoting copper fittings at last year's price can turn a profitable job into a marginal one. Always check current merchant prices before building a materials quote.
• Underestimating travel time between jobs. On days with multiple jobs or a site visit followed by work elsewhere, travel time is a real cost. If your schedule means the job will eat into travel time between other appointments, the effective rate on this job is lower than the hourly figure suggests.
• Not accounting for waiting time. On busy jobs with multiple trades, waiting for materials deliveries, waiting for a customer to arrive, or waiting for another trade to finish before you can start is real time that costs you. On reactive maintenance jobs especially, factor in the likely waiting time.
• Forgetting call-out or diagnostic time. If you attend a site to assess and diagnose a problem before quoting the fix, that time has a cost. Either charge a call-out fee upfront or ensure the diagnostic time is recovered in the quote for the repair work.
• Assuming best-case conditions in old properties. Properties built before 1980 routinely have non-standard pipe sizes, wiring systems, fixings, and structural configurations. What takes an hour in a modern build can take three hours in a Victorian terrace. Price accordingly.
• Accepting a customer's estimate of how quick a job should be. Customers often have no idea how long trade work actually takes. "It should only take you an hour" is not a basis for pricing. Your estimate of the hours is what matters, not theirs.
• Quoting low to win work and hoping to recover margin elsewhere. This approach rarely works. You win loss-making jobs and miss better opportunities. Price each job on its own merits.
