Timesheets for Trade Businesses UK 2026 — Tracking Labour Hours for Job Costing and Payroll

Why Timesheets Matter for Trades

Plenty of trade businesses run for years without proper timesheets and seem to get by. The problem is they're flying blind on the one number that decides whether they're profitable. Here's what accurate hours give you.

Accurate Job Costing

The real cost of a job is materials plus labour plus a share of your overheads. Materials are easy to track. Labour is where most operators guess — and guessing is how an apparently profitable job turns out to have lost money once you count the three extra days nobody logged. If you record the hours each person spent on each job, you can multiply by their true hourly cost (wage plus employer's National Insurance, pension, holiday and tool allowance) and see the actual labour cost per job. That single figure tells you more about the health of your business than almost anything else.

Payroll Accuracy for Employees and Subcontractors

If you employ people, their pay depends on the hours they worked — including overtime, weekend rates and any travel time you pay for. Without a timesheet you're relying on memory, which leads to overpayment, underpayment and arguments. For CIS subcontractors you're usually paying against an agreed price or day rate rather than hours, but you still want a record of days and dates worked to reconcile against their invoices, support your CIS deductions and verification, and spot when a "day" was actually a couple of hours.

Proving Hours for Variations and Disputes

On day-rate and time-and-materials work, the timesheet is your evidence. When a client queries an invoice or disputes that a variation took as long as you say, dated hours signed off on site are far harder to argue with than a number you've quoted from memory weeks later. The same applies to contra-charges, delay claims and main-contractor accounts. A clean record of who was on site, when, and doing what protects you when the relationship gets tense.

Spotting Unprofitable Jobs and Underquoting

Once you have real hours against real jobs, patterns appear. You find that bathrooms always overrun your estimate by 20%, that a particular client's "quick" jobs never are, or that one type of work consistently eats labour for thin margins. That's the feedback loop that fixes underquoting: you stop pricing from optimism and start pricing from what the work actually takes. Without timesheets, you repeat the same costing mistakes indefinitely because nothing ever tells you they were mistakes.

What to Capture on a Timesheet

A good trade timesheet records enough to cost a job and run payroll, without being so fiddly that nobody fills it in. The core fields are:

• Employee or operative name: who did the work.
• Date: one row per person per day is the cleanest structure.
• Job or site: the job number, client name or address, so hours land against the right job in your costing.
• Start and finish times: actual clock-on and clock-off, not rounded guesses.
• Breaks: unpaid breaks taken, so you can calculate paid hours correctly.
• Travel time: recorded separately if you pay for it or want to cost it — van time to a distant site is a real labour cost even when the customer isn't charged for it.
• Overtime: hours beyond standard, flagged so the right rate applies.
• Materials or notes: a line for anything bought on the day or relevant to the job (a delay, a snag, a variation) that helps you reconcile later.

Capturing the job or site reference is the single most important field for costing. A timesheet that records hours but not which job they belong to is fine for payroll and useless for working out what each job cost. If you only add one discipline, make it this one.

Paper vs Spreadsheet vs App-Based Time Tracking

There's no single right method — it depends on your team size, how spread out your work is, and how much you trust the data. Here's how the three common approaches compare.

Paper Timesheets

A paper book or printed weekly sheet is cheap, needs no signal and works for a sole trader or a tight two-person outfit. The downsides show up as you grow: sheets get lost, smudged or filled in on a Friday from memory, the hours are often rounded, and someone has to retype everything into payroll and costing. Paper is fine as a starting point, but it scales badly and the data is only as honest as a tired memory at the end of the week.

Spreadsheet Timesheets

A shared spreadsheet is the natural next step. It does the maths for you, you can total hours by job, and it's free if you already have the software. The weaknesses are that times are still entered manually (so still guessable), version control gets messy with several people editing, and there's no proof anyone was actually on site. For a small organised team it's a big improvement on paper and often good enough for a long time.

App-Based Time Tracking

A dedicated app turns timesheets into something the team does in seconds from a phone. The features that matter for trades are:

• Clock-in/out: the operative taps to start and stop against a specific job, so the time is captured live rather than reconstructed later.
• GPS: a location stamp on clock-in confirms the person was at the site, which settles "were we actually there" questions and supports billing.
• Photo proof: a quick site photo at the start or end of the day gives you a visual record alongside the hours.

The payoff is that hours flow straight into job costing and payroll without re-keying, and the data is captured in real time rather than guessed. The trade-off is the monthly cost and getting the team into the habit. For anything beyond a handful of people across multiple sites, app-based tracking usually pays for itself in recovered hours and tighter costing.

How Timesheets Feed Job Costing and Quoting

Timesheets are only worth the effort if the numbers go somewhere. The loop looks like this. Hours are recorded against a job. Each person's hours are multiplied by their true hourly cost — not just their wage, but wage plus employer's NI, pension contributions, holiday accrual and a share of tools, insurance and van costs. Add materials and a slice of overhead and you have the real cost of the job. Compare that to what you charged and you have your actual margin, not the one you hoped for at quote stage.

That actual margin is the feedback that makes your next quote better. When you can see that a job type reliably takes 40 hours and your estimate assumed 30, you adjust. Over time your estimates converge on reality, your quotes stop leaking money, and you can walk away from work that the numbers show never makes sense. Quoting accuracy isn't a one-off skill — it's the output of consistently comparing quoted hours to actual hours, and that comparison is impossible without timesheets.

The Legal Angle: Records You're Expected to Keep

Beyond running a tidy business, there are record-keeping expectations around working time and pay. None of the below is a substitute for current GOV.UK guidance or professional advice, but it shows why keeping hours matters.

• Working time records: the Working Time Regulations 1998 set limits such as the 48-hour average working week (which workers can opt out of) and rest break entitlements. Employers are expected to keep adequate records to show they're complying, and timesheets are the obvious source of that evidence.
• National Minimum Wage record-keeping: minimum wage law requires employers to keep records sufficient to prove each worker was paid at least the relevant rate. Records generally need to be kept for several years, and HMRC can ask to see them. For workers near the minimum, accurate hours are what proves the hourly rate was met once you divide pay by time worked.
• Holiday pay: holiday entitlement and pay are usually based on hours and average pay over a reference period. For workers with variable hours, you can't calculate holiday pay correctly without a reliable record of the hours actually worked.

The practical point is that good timesheets do double duty: they cost your jobs and they form the backbone of the records you're expected to hold anyway. Confirm the specifics for your situation with an accountant or HR adviser.

Getting a Small Team to Actually Fill Them In

The best system is the one that gets used. Trades people are not famous for paperwork, so the barrier to entry has to be low and the reasons have to be honest.

• Make it quick: if filling in a timesheet takes more than a minute, it won't happen consistently. A phone clock-in beats a paper sheet every time on this measure.
• Capture it daily, not weekly: reconstructing a whole week on Friday afternoon produces fiction. Logging at the end of each day, or live, keeps it accurate.
• Explain the why: "this is how we make sure we're pricing jobs properly so the business stays healthy and your wages get paid" lands better than "head office wants it".
• Lead by example: if the owner or supervisor fills theirs in, the team follows. If they don't, nobody will.
• Close the loop: share back what the data showed — "that job ran over, here's what we learned" — so the team sees their input being used rather than disappearing into a drawer.
• Tie it to getting paid: a simple rule that hours have to be in before payroll runs gives a natural, fair deadline.

Frequently Asked Questions

Do I need timesheets if I only have subcontractors?

You won't run payroll for CIS subcontractors, but you still benefit from recording days, dates and which job they worked on. It lets you reconcile their invoices, support your CIS deductions, cost the labour against the job, and prove who was on site if a client query comes up.

Should I pay for travel time?

Whether you pay for travel depends on your contracts and arrangements with your team, and the rules around minimum wage and travel can be nuanced. Either way, it's worth recording travel separately, because van time is a genuine labour cost on a job even when the customer isn't billed for it. Take advice on the pay side.

How long should I keep timesheet records?

Pay and minimum wage records generally need to be kept for several years, and other records have their own retention periods. Check the current GOV.UK guidance or ask your accountant for the periods that apply to you — keeping them longer rather than shorter is the safer habit.

Is an app worth it for a small team?

Often yes, once you're beyond a sole trader. The time saved re-keying hours, the accuracy of live capture, and the job-costing insight usually outweigh the monthly cost. For a one-person business a spreadsheet may be all you need.

The Bottom Line

Timesheets aren't admin for its own sake — they're how you turn vague effort into hard numbers. Capture who worked, on what job, for how long, and you unlock accurate job costing, correct pay, evidence for disputes, and the feedback that fixes underquoting. Whether you start with a paper sheet, move to a spreadsheet, or jump straight to an app, the discipline matters more than the tool. Get the hours right and you stop guessing about the single biggest cost in your business — which is the foundation of running a profitable, organised trade.
