UK Timesheets for Trade Businesses: What to Record and How to Choose Software

UK employers need sufficient records to demonstrate minimum-wage compliance, but no particular timesheet format is prescribed. For trade businesses, aim for a consistent record of actual hours that the office can review alongside job information, without chasing everyone’s best guess.

This guide provides a practical template, a worked example and criteria for choosing software. At Intrflex, we bring timesheets and leave logging into the same system as jobs and scheduling, keeping time records within your wider operational workspace.

The requirement is sufficient evidence, not a prescribed timesheet

Choose a recording method that preserves actual hours and lets the office review them alongside the relevant pay records. Start with the evidence you need, not the software’s feature list.

For minimum-wage purposes, employers must keep sufficient records for each worker and every pay reference period. GOV.UK explains that pay reference periods are usually linked to how often someone is paid, such as weekly or monthly. This is the period over which minimum-wage pay is assessed. No particular record format is prescribed, as HMRC’s minimum-wage record guidance makes clear.

Paper and computer records are both permitted. The practical requirement is that you must be able to produce the information for one worker and one pay reference period in a single document on request.

A contract or payslip isn’t a substitute for evidence of time worked: contracted hours and payslip totals alone don’t demonstrate actual hours. Choose a process that records what happened, rather than simply copying what the rota said should happen.

Build a timesheet that captures the whole working day

A daily total tells the office how long someone recorded, but not which job, break or activity needs checking. Split the day into clear intervals so a manager can follow the sequence without piecing it together from messages. “Eight hours” shouldn’t need a detective attached.

Use this copyable checklist as a starting point. These are recommended operational fields, not universally mandated timesheet columns:

- Worker identifier: name and a consistent staff reference.
- Date: the day the activity took place.
- Job or site reference: enough detail to identify where the activity belongs.
- Activity start and finish: actual times for each interval, rather than scheduled times.
- Actual break intervals: when each break started and ended.
- Activity category: record site work, inter-site travel, waiting and training separately where relevant. These reflect categories in GOV.UK’s recommended minimum-wage records, which explain that the necessary detail varies by worker and type of work.
- Leave or absence: keep these entries distinguishable from time worked.
- Total duration: the duration of each activity, with a daily total for checking.
- Overtime classification and applicable rate: include these where relevant to the pay calculation.
- Exception notes: explain interruptions, missing information or an unusual sequence.
- Correction details: retain the original and revised values, reason, editor and date.

Record what happened first, then decide its pay or billing treatment. Keeping those steps separate gives the office a clear account of the day to work from.

• Use intervals, not just a daily total. “Eight hours” can hide which job, break or activity needs checking. Treat these as recommended operational fields, not universally mandated timesheet columns.
• Worker identifier and date: enter the worker’s name, a consistent staff reference and the date the activities took place.
• Job or site reference: identify the relevant job or location clearly enough for the office to recognise it without chasing messages.
• Activity start and finish: record actual times for each activity rather than copying scheduled hours. Keep the day’s sequence clear.
• Actual break intervals: enter when each break started and ended, rather than automatically inserting a standard deduction.
• Activity category: separate site work, inter-site travel, waiting and training where relevant. GOV.UK’s recommended minimum-wage records cover these categories and explain that the necessary detail varies by worker and work type.
• Leave and absence: identify these separately so they remain distinguishable from time worked when the office reviews the record.
• Total duration and exception notes: calculate each interval and the daily total. Explain interruptions, missing details or unusual sequences while they’re fresh.
• Overtime classification and applicable rate: include these where relevant to the pay calculation. Record what happened before deciding its pay or customer-billing treatment.
• Correction details: preserve the original entry, revised value, reason, editor and date. Final check: can a manager understand the day without reconstructing it from texts and calls?

Separate recorded time, payable hours and customer billing

A customer invoice and a worker’s pay calculation answer different questions. One concerns what you can charge under the customer agreement. The other concerns which hours count for the relevant pay calculation. Keep both separate from the record of what happened.

Consider this hypothetical two-site day: site A work from 08:00 to 10:30, inter-site travel until 11:00, waiting until 11:30, then site B work until 12:30. A break runs from 12:30 to 13:00, followed by more site B work until 15:30 and training until 16:00. That’s an eight-hour span, including a 30-minute break. These intervals illustrate recording, not a legal determination of payable hours.

Use that record to make three separate decisions. First, establish the activities and their durations. Second, determine which hours count for the pay calculation, using the relevant rules, including working hours for minimum-wage purposes. Third, check what the customer agreement allows you to bill. Don’t assume one classification answers all three questions.

For example, if the agreement makes inter-site travel non-billable, retain that travel interval in the underlying record. “Not charged to the customer” mustn’t become “never happened”.

Labour-cost analysis needs another input: an appropriate cost rate. Decide whether you’re measuring wages alone or a broader employment cost, then use a rate that matches. A customer charge-out rate is neither the worker’s wage nor their full employment cost. Keep those rates distinct so your job-cost figures answer the question you intended.

Set a review process that catches gaps before payroll

A deadline only helps when someone owns the follow-up. Name a reviewer who’ll chase missing submissions, raise queries and check that corrections are resolved before payroll preparation. Treat this as an operational routine, not a statutory procedure: everyone should know what to record, when to submit it and who handles questions.

Ask crews to record time daily, then set a clear submission deadline that leaves room for review. The reviewer should check overlapping intervals, missing job references, unexplained differences from the schedule, break entries and unusual overtime. Use the schedule to prompt questions, not to replace actual hours. A planned finish time isn’t evidence that someone packed up then.

When an entry needs correcting, preserve the original entry alongside the revised value, reason, editor and date. Give workers a clear route to query a change, such as contacting the named reviewer, and keep unresolved questions visible until someone has followed them through.

For a hypothetical example, suppose a timesheet shows a 16:30 finish but the schedule says 16:00. That 30-minute difference should trigger a conversation, not an unexplained overwrite. If the worker stayed to complete a task, retain the actual finish and note the explanation. If they confirm an entry error, document the correction and its reason. The aim is a resolved record, not a tidy-looking total.

• Name the person who owns follow-up. A deadline only helps when someone chases missing records and resolves questions. Treat this as a practical review routine, not a statutory procedure.
• Record time daily. Ask crews to enter actual activities, breaks and exceptions while the details are fresh, rather than reconstructing the week on Friday afternoon.
• Set a clear submission deadline. Leave enough time before payroll preparation for the named reviewer to raise queries and workers to respond.
• Check the day’s sequence. Look for overlapping intervals, missing job references, unclear break entries and unusual overtime. Flag gaps for discussion rather than filling them with assumptions.
• Compare records with the schedule. Use differences to prompt questions, not to replace actual hours. A planned finish time doesn’t tell you when someone stopped working.
• Preserve correction details. Keep the original entry, revised value, reason, editor and date. Give workers a clear route to question changes through the named reviewer.
• Discuss discrepancies before changing entries. In a hypothetical example, a 16:30 recorded finish against a 16:00 scheduled finish triggers a conversation. Retain genuine extra time with an explanation, or document a confirmed entry error and its correction.
• Track queries through to resolution. Keep an owner and next action against each outstanding question so missing information doesn’t disappear into a message thread.

Keep records for the right period and make them retrievable

Retention follows the record’s legal purpose, not whether it lives in a spreadsheet or an app. Set your retention schedule around the obligations each record supports, rather than using one deletion date for everything.

Under GOV.UK’s minimum-wage retention guidance, relevant records must be kept for at least six years if they were created on or after 1 April 2021, or still had to be retained on 31 March 2021. The clock starts on the last day of the pay reference period following the one covered, not the date you created the record. For a worker paid each calendar month, GOV.UK’s example means May 2021 records must be retained until the end of June 2027.

PAYE record retention generally runs for three years from the end of the relevant tax year. That’s a separate rule, not permission to delete records still needed for minimum-wage evidence or another purpose.

Test retrieval before you need it: can the office assemble one worker’s hours and supporting pay information for one pay reference period into a single document? That single-document requirement makes accessibility as important as storage. Try retrieving a completed period now and resolve any gaps.

Choose proportionate timekeeping, not unnecessary surveillance

Collect the information needed to solve a defined problem, not everything a tool can capture. If you need reliable start and finish records, assess options against that purpose rather than choosing the most monitoring features.

The ICO’s guidance on monitoring workers requires an appropriate lawful basis, a clear purpose and the least intrusive effective approach. Give workers privacy information explaining what you collect, why and how you’ll use it. Make this part of the rollout, not a policy document everyone discovers afterwards.

For location data, distinguish a check at a relevant event from continuous tracking throughout the day. Examine when collection operates, who can access the information and how long you’ll retain it against your stated purpose. Don’t treat either approach as automatically lawful.

Before introducing monitoring, assess whether you need a data protection impact assessment (DPIA): a structured assessment of privacy risks and safeguards. The ICO requires a DPIA before processing likely to pose a high risk.

Biometrics need additional safeguards. Fingerprints or facial data used to uniquely identify workers are special-category data. You need both a lawful basis and an appropriate special-category processing condition, plus a DPIA completed before processing begins, as the ICO’s biometric timekeeping guidance explains. Consider less intrusive alternatives before choosing this route.

Choose Intrflex when timesheets are part of a wider job-management problem

Paper or a spreadsheet can serve as your recording method for minimum-wage evidence. But when you’re coordinating mobile crews, also consider where jobs, schedules and field updates are managed. A timesheet won’t solve the wider problem if the office still has to search several places to understand what’s happening on site.

At Intrflex, we bring timesheets and leave logging together with job management, scheduling, quotes, invoicing and field updates. That gives your team one operational system rather than separate tools for each stage of the work. The practical benefit is less fragmentation between office and site, with fewer places to check when organising the day.

Think about a schedule change. The office needs to coordinate the revised plan, while the crew needs the right job details. Later, someone may need to understand how the work progressed. Managing these activities in one system helps keep the operational context accessible instead of scattered across paperwork and message threads. Friday afternoon shouldn’t depend on everyone’s best guess.

That’s the reason to consider Intrflex: not simply to replace a paper form with a screen, but to bring time recording into the system you use to run the work. Focus on the handoffs that currently create chasing, duplicated admin or communication gaps. Those are the problems a broader job-management system should help you address.

Decide whether you need an hours record or a shared operational workspace

Recording time answers “what hours did someone work?” Coordinating a trade business also means deciding who’s going where, giving crews the right instructions and keeping the office informed. Choose based on which problem you need to solve, not how many features fit on a pricing page.

A consistent manual record may suit a straightforward process if one person can collect entries, resolve questions and prepare the records without repeated chasing. The deciding factor isn’t team size. It’s whether the process stays manageable when work changes.

Intrflex is the stronger fit when you also need one place for jobs, schedules, crew coordination, quotes and invoices. Our real-time updates, photos and on-site task lists or sign-offs help teams share progress and instructions without relying on a relay of phone calls. That’s a broader operational need than collecting an hours total.

Keep the purchasing decision separate from the evidence test. More features don’t automatically make records legally sufficient: they still need to demonstrate minimum-wage compliance for each worker and pay reference period. Choose the workspace for how you run the business, and maintain a clear process for the records you need.

Evaluate the software with one real working week

Run a short evaluation using representative work, rather than turning the decision into a feature-count contest. Bring an anonymised week with multiple sites, a schedule change, leave and an hours query. The useful test is whether your team can follow the work and handle the handoffs without another round of “who’s got that information?”

Use that week to guide the walkthrough:

- Identify the people involved. Name who records time, who reviews it and who prepares pay information. Include the office and field perspectives, not just the person buying the software.
- Follow a change through the workspace. Move a planned job and review how the team uses schedules, job details and field updates to coordinate the revised day. Judge how easily people can find what they need.
- Review the operational picture. Look at whether jobs, leave and crew coordination are easier to manage together. Note which existing calls, messages or duplicate records you could replace.
- Document specialist requirements separately. Write down what your process needs for payroll handoff, record retrieval, corrections and any specialist timekeeping. Keep these requirements distinct from your assessment of the wider job-management workspace.

Finish with a short decision note: which handoffs become simpler, which processes still need a named owner and what needs changing before rollout.

Book an Intrflex demo and bring that working week. We’ll walk through how jobs, scheduling, timesheets and field updates fit into the way your team runs its work.

• Run a short, practical evaluation. Use representative work to judge the fit, not a feature-count contest.
• Bring an anonymised working week covering multiple sites, schedule changes, leave and an hours query. Give the walkthrough something real to work with.
• Name who records time, who reviews it and who prepares pay information. Include both office and field perspectives.
• Follow a schedule change through the workspace. Assess how easily the office and crew can find job details, share updates and coordinate the revised plan.
• Keep a separate requirements checklist for payroll handoff, record retrieval, corrections and specialist timekeeping. Don’t let the wider workspace assessment obscure these needs.
• Book an Intrflex demo and bring that working week. We’ll walk through jobs, scheduling, timesheets and field updates using the work your team actually handles.

Complete the suggested record for one representative working day. Then trace its route from site to office: where do details go missing, and who has to chase them? Use those gaps to decide what needs fixing first.

If you’re choosing a broader operational system, book an Intrflex demo with that example ready. Give the walkthrough a real problem to solve.
