A guard covers another site at short notice. The shift finishes the next morning, the cover rate differs from their usual rate, and the supervisor who saw the handover is off when payroll needs approval.
A weekly total of “40 hours” cannot explain all of that. Payroll needs to know which work those hours represent, what the employer agreed to pay and who checked the record.
For security companies, a practical starting point is to keep each overnight shift intact from the original record through to the approved earnings. This guide follows one fictional guard's week, then shows the checks to complete before payroll closes.
The payroll preparation principles apply across the UK. The working-time discussion below uses Great Britain guidance; Northern Ireland has separate legislation and guidance. The example covers an adult employee doing hourly paid, waking security work, not a sleep-in arrangement or self-employed subcontractor.
What security payroll needs from each site
Ask the site supervisor to approve a record that answers five questions:
- When did the work happen? Record both dates, start and finish times, and breaks actually taken.
- Which assignment was covered? Keep the site and shift reference alongside the employee's record.
- What rate was agreed? Distinguish the normal assignment rate, a different cover rate and any additional premium.
- What changed? Explain late relief, extra handover time or a corrected clocking entry.
- Who checked it? Name the approver and complete approval before the payroll cut-off.
Choose a deputy for overnight and weekend approvals. The person authorising the cover rate may be different from the supervisor confirming attendance: payroll needs both decisions. A client's invoice rate is not evidence of what the guard should earn.
Worked example: one guard, two sites and a night premium
Alex is a fictional guard aged 30, paid weekly. In this illustrative week, the employer agrees £14 an hour for ordinary Site A work, £15 an hour for a distinct Site B cover assignment, and an extra £2 an hour for eight qualifying night hours at Site A.
The cover rate is the agreed ordinary rate for that assignment, not an overtime enhancement. The night premium is additional pay for the same eight hours already included in basic night earnings.
| Approved earnings item | Hours used in calculation | Rate | Gross earnings |
|---|---|---|---|
| Site A daytime work | 24 | £14.00 | £336.00 |
| Site B cover assignment | 8 | £15.00 | £120.00 |
| Site A night work: basic pay | 8 | £14.00 | £112.00 |
| Additional premium on those same night hours | 8 | £2.00 | £16.00 |
| Total for 40 hours worked | 40 unique hours | — | £584.00 |
Figures show gross earnings before deductions. They exclude expenses, leave, other payments and employer costs. The premium row does not add eight more working hours.
Alex's night attendance runs from 22:00 on Tuesday 13 October to 06:30 on Wednesday 14 October 2026. During it, Alex takes a genuine 30-minute unpaid break with another guard providing relief. That leaves eight worked and paid hours. In this example, the contract awards the premium for all eight working hours; that is an illustrative agreement, not a statutory night rate. Any required handover is already included in the recorded working time.
Before approval, the supervisor checks the cross-midnight dates and actual break. The cover manager confirms Site B's eight hours and £15 rate. Payroll can then reconcile £336 + £120 + £112 + £16 = £584.
Applying Alex's usual £14 rate to all 40 hours would produce £560, missing £8 from the cover assignment and £16 of agreed night premium. That £24 difference is why a total-hours figure alone is insufficient.
Record overnight shifts without losing or duplicating time
Keep the start and finish date visible. A shift beginning on Tuesday and ending on Wednesday should remain traceable as one assignment, even if a system allocates its hours across calendar days or pay periods.
At a payroll boundary, document how each portion is allocated and reconcile back to the original shift. Do not include the full shift in one period and its after-midnight hours again in the next. A late clock-out or delayed relief should trigger a check of what actually happened, including required handover time.
Breaks also need evidence. Do not automatically deduct a scheduled break when the guard remained responsible for the post. Check actual duties and availability when deciding how time should be treated. GOV.UK explains what counts as working time for hourly paid workers' minimum-wage calculations.
When a shift crosses a UK clock change, check actual elapsed time and the time zone recorded. A simple subtraction of displayed local clock times can miss the repeated hour when clocks go back, or overstate elapsed time when clocks go forward. Alex's example does not cross a clock change.
Agree premiums, then check minimum wage separately
A night shift does not automatically attract a higher statutory minimum-wage rate. Pay any enhancement required by the employment agreement, and record which hours qualify. GOV.UK's night-working guidance explains that there is no separate higher night minimum wage.
Similarly, check the contract's overtime terms instead of assuming every extra shift is paid at time-and-a-half. Keep the basis for each rate available to the person reviewing earnings. See GOV.UK's overtime guidance.
For minimum-wage purposes, gross pay and qualifying pay are not always the same. For time work and output work, the premium element of overtime or shift pay is excluded. In Alex's hourly paid example, the £16 night premium must therefore be excluded from minimum-wage pay. Do not use £584 divided by 40 as a complete compliance check. Other pay elements, deductions and all qualifying hours also need assessment for the relevant pay reference period. Follow HMRC's minimum-wage calculation guidance.
Our minimum-wage employer guide covers the wider review. This article's earnings table is a payroll preparation example, not a minimum-wage compliance certificate.
Keep night-work responsibilities alongside payroll preparation
Correct pay does not establish that a shift pattern meets working-time requirements. In Great Britain, the general night-work limit is an average of eight hours in each 24-hour period; special hazards and heavy mental or physical strain have stricter rules. The general rule is not simply an eight-hour maximum for every individual shift.
Exceptions can apply, including to some security and surveillance arrangements, with compensatory-rest requirements. Do not assume that employing security guards removes all working-time obligations. Check the specific arrangement against GOV.UK's exceptions guidance, and get advice where its application is unclear.
Employers must also offer free health assessments before night work starts and regularly afterwards. Keep confidential health information separate from routine payroll handover notes. See night-worker health assessments. For Northern Ireland, use nidirect's working-at-night guidance and the Labour Relations Agency for employment guidance.
How Workmax connects approved hours and payroll
With Workmax Time Tracking and Payroll enabled, approved hours feed payroll preparation. Your payroll team reviews rates and earnings, calculates pay and checks exceptions before completing the run. Explore Workmax Payroll for the workflow and module options.
For a security business, the useful demonstration is your own representative week: an overnight shift, a cover assignment with a different rate, an agreed premium and a correction. Bring those inputs to the walkthrough and check how each appears in the earnings review. Confirm how your setup handles overnight allocation and premium entry before relying on it for a live pay run.
The £584 example above is an illustrative calculation, not a completed Workmax security-company pay run. It does not demonstrate automatic night-premium rules or automatic splitting of cross-midnight shifts.
Connected records can reduce repeated entry and the time spent investigating differences. Measure that benefit using time spent collecting hours, checking approvals and preparing payroll before and after a change. Staff time released creates capacity; cash savings depend on costs actually avoided and the software and setup costs incurred. There is no fixed saving promised here.
Before the payroll cut-off
Use this handover checklist for the week's security assignments:
- Confirm both dates and actual working time for every overnight shift.
- Check breaks actually taken and any late relief or additional handover.
- Match cover hours to the authorised assignment rate.
- Identify qualifying premium hours without counting the hours twice.
- Resolve missing clocking entries with an explanation and named reviewer.
- Complete site-manager approval, with deputy cover where needed.
- Reconcile unique hours and gross earnings; perform the separate minimum-wage check.
- Include leave, absence and other authorised pay changes before final review.
For the wider process, use the Workmax payroll hub. If your business also supplies cleaning teams, the cleaning-company payroll guide covers travel and holiday considerations for that workflow.
